# Bump Version Skill

Automate the complete OSS version bump and release workflow for Skyvern.

## What this does


1. Validates and updates version in `pyproject.toml`
2. Builds Python SDK with Fern
3. Builds TypeScript SDK with Fern
4. Creates commit with all changes
5. Optionally runs SDK tests
6. Pushes branch and creates PR

## Version argument

The version can be provided as an argument or you'll be prompted:

- If `$ARGUMENTS` is provided, use it as the new version
- If not provided, ask user for the new version number
- Validate it follows semver format: `MAJOR.MINOR.PATCH` (e.g., `1.0.14`, `1.1.0`, `2.0.0`)

**Semver guidance:**
- PATCH: Bug fixes, backwards compatible (e.g., 1.0.13 → 1.0.14)
- MINOR: New features, backwards compatible (e.g., 1.0.13 → 1.1.0)
- MAJOR: Breaking changes (e.g., 1.0.13 → 2.0.0)

## Step-by-step process

### 1. Get and validate version

- Read current version from `pyproject.toml` line 3
- Determine new version from `$ARGUMENTS` or prompt user
- Validate semver format using regex: `^\d+\.\d+\.\d+$`
- Confirm with user: "Bumping version from {current} to {new}. Continue?"

### 2. Create feature branch

```bash
git checkout -b bump-version-$ARGUMENTS
```

Branch naming: `bump-version-{version}` (e.g., `bump-version-1.0.14`)

### 3. Update pyproject.toml

Update line 3 in `pyproject.toml`:

```toml
version = "{new_version}"
```

Use the Edit tool to make this single-line change.

### 4. Build Python SDK

```bash
bash scripts/fern_build_python_sdk.sh
```

- Wait for completion
- Check output for errors
- Fern reads version from `pyproject.toml`

### 5. Build TypeScript SDK

```bash
bash scripts/fern_build_ts_sdk.sh
```

- Wait for completion
- Check output for errors
- Verify `skyvern-ts/client/package.json` version matches new version

### 6. Review changes

```bash
git status
git diff --stat
```

Show user:
- Number of files changed
- Which files were modified
- Summary of changes

### 7. Commit changes

```bash
git add .
git commit -m "Bump version to {version}

- Update version in pyproject.toml
- Regenerate Python SDK with Fern
- Regenerate TypeScript SDK with Fern

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>"
```

### 8. Verify SDKs (optional)

Ask user: "Would you like to run SDK tests to verify nothing broke?"

If yes:
- Python SDK tests: `pytest tests/sdk/python_sdk/`
- Note that TypeScript tests require manual Chrome setup (see `tests/sdk/README.md`)
- Display test results
- If tests fail, STOP and report errors - do not proceed to push

If no:
- Skip to push step

### 9. Push and create PR

Ask user: "Ready to push and create PR?"

If yes:

```bash
git push -u origin bump-version-{version}

gh pr create --title "Bump version to {version}" --body "## Summary
Bump Skyvern OSS version to {version}

## Changes
- Updated version in \`pyproject.toml\`
- Regenerated Python SDK with Fern
- Regenerated TypeScript SDK with Fern

## Deployment
After merge, GitHub will automatically:
- Deploy Python package to PyPI (version change in \`pyproject.toml\`)
- Deploy TypeScript package to NPM (version change in \`package.json\`)

## Testing
- [ ] Python SDK tests passed locally
- [ ] TypeScript SDK tests passed locally (if applicable)

🤖 Generated with [Claude Code](https://claude.com/claude-code)"
```

Display the PR URL to the user.

## Important notes

- **Single PR**: All changes (version bump, SDK generation, commit) happen in one PR
- **Fern sync**: Fern reads version from `pyproject.toml` and syncs to `package.json`
- **Testing**: SDK tests require `.env` with `SKYVERN_API_KEY`
- **Deployment**: Automatic on PR merge via GitHub Actions
- **No force push**: Never use `--force` when pushing

## Error handling

If any step fails:
1. Display the error message clearly
2. Explain what went wrong
3. Ask user how to proceed (fix, skip, or abort)
4. Do not continue to next steps if critical operations fail

# Skyvern: AI Browser Automation

Skyvern automates browser-based workflows using LLMs and computer vision. It navigates websites it has never seen before, filling forms, extracting data, and completing multi-step tasks via a simple API.

**SDK reference (all methods, parameters, types in one page):** https://skyvern.com/docs/sdk-reference/complete-reference

## When to use Skyvern

- The user needs to **interact with a website** programmatically (fill forms, click buttons, navigate pages)
- The user needs to **extract structured data** from a website (scrape prices, addresses, table rows)
- The user needs to **download files** from a web portal (invoices, reports, statements)
- The user needs to **log in** to a website and perform actions behind authentication
- The user needs to **automate a multi-step workflow** across one or more websites
- The user needs to **run browser automation from an AI assistant** (Claude, Cursor, Windsurf)

## Capabilities

### Run a single task

Execute a one-shot browser automation with natural language instructions.

**Inputs:**
- `prompt` (required): Natural language description of what to do
- `url` (required): Starting page URL
- `data_extraction_schema` (optional): JSON schema for structured output
- `proxy_location` (optional): Country code for geo-routing (e.g., `US`, `DE`)

**Python SDK:**
```python
from skyvern import Skyvern

client = Skyvern(api_key="YOUR_API_KEY")
result = await client.run_task(
    prompt="Get the title of the top post on Hacker News",
    url="https://news.ycombinator.com",
)
```

**TypeScript SDK:**
```typescript
import Skyvern from "@skyvern/client";

const client = new Skyvern({ apiKey: "YOUR_API_KEY" });
const result = await client.runTask({
    prompt: "Get the title of the top post on Hacker News",
    url: "https://news.ycombinator.com",
});
```

**REST API:**
```bash
curl -X POST https://api.skyvern.com/api/v2/run \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Get the top post title", "url": "https://news.ycombinator.com"}'
```

### Extract structured data

Define a JSON schema to get consistent, typed output from any page.

```python
result = await client.run_task(
    prompt="Extract the top 3 posts",
    url="https://news.ycombinator.com",
    data_extraction_schema={
        "type": "object",
        "properties": {
            "posts": {
                "type": "array",
                "items": {
                    "type": "object",
                    "properties": {
                        "title": {"type": "string"},
                        "url": {"type": "string"},
                        "points": {"type": "integer"}
                    }
                }
            }
        }
    },
)
```

### Build multi-step workflows

Chain task blocks, loops, conditionals, data extraction, and file operations into reusable automations.

**Block types:** NavigationBlock, ActionBlock, ExtractBlock, LoopBlock, TextPromptBlock, LoginBlock, FileDownloadBlock, FileParseBlock, UploadBlock, EmailBlock, WebhookBlock, ValidationBlock, WaitBlock, CodeBlock, ForLoopBlock, FileURLParsingBlock, DownloadToS3Block, SendEmailBlock.

```python
workflow = await client.create_workflow(
    title="Invoice Downloader",
    blocks=[...],  # See workflow blocks reference
)
run = await client.run_workflow(workflow_id=workflow.workflow_id)
```

### Manage browser sessions

Persist a live browser across multiple tasks to maintain login state, cookies, and page context.

```python
session = await client.create_session()
# Run multiple tasks on the same browser
await client.run_task(prompt="Log in", url="https://example.com", browser_session_id=session.browser_session_id)
await client.run_task(prompt="Download invoice", url="https://example.com/billing", browser_session_id=session.browser_session_id)
await client.close_session(session.browser_session_id)
```

### Handle authentication

Store passwords, TOTP/2FA secrets, and credit cards securely. Skyvern auto-fills login forms and generates 2FA codes during automation.

**Supported credential providers:** Skyvern vault (built-in), Bitwarden, 1Password, Azure Key Vault.

### Use via MCP server

Connect AI assistants directly to browser automation. The MCP server exposes 75+ tools.

**Install for Claude Code:**
```bash
claude mcp add skyvern-cloud -- npx @anthropic-ai/skyvern-mcp@latest --skyvern-api-key YOUR_API_KEY
```

**Install for Cursor/VS Code:** Add to MCP config:
```json
{
  "mcpServers": {
    "skyvern": {
      "command": "npx",
      "args": ["@anthropic-ai/skyvern-mcp@latest", "--skyvern-api-key", "YOUR_API_KEY"]
    }
  }
}
```

### Use via CLI

```bash
pip install skyvern
export SKYVERN_API_KEY="YOUR_KEY"

skyvern browser session create          # Start a cloud browser
skyvern browser act "Click the login button"  # Natural language action
skyvern browser extract '{"title": "string"}' # Extract structured data
skyvern browser screenshot              # Capture screenshot
skyvern task run --prompt "..." --url "..."   # Run a task
skyvern workflow run --id wf_xxx        # Run a workflow
```

## Constraints

- Tasks run in cloud browsers managed by Skyvern (or self-hosted browsers). They do not run in the user's local browser by default.
- Each task step consumes credits. Set `max_steps` to control costs.
- Browser automation takes 30-120 seconds per task depending on complexity.
- Skyvern works best with natural language prompts that describe the goal, not low-level click instructions.
- For websites that require login, credentials must be stored via the credentials API before running tasks.
- Self-hosted deployments require Docker and a PostgreSQL database.

# QA — Validate Frontend and Backend Changes

Read the diff, classify what changed, and run the right validation path: browser QA for frontend/browser changes, API validation for backend surface changes, repo-native validation for backend-internal changes, and both for mixed changes.

<!-- NOTE: This content is maintained in three places — keep all in sync:
     1. skyvern/cli/skills/qa/SKILL.md         (bundled with pip package — canonical)
     2. .claude/skills/qa/SKILL.md              (project-local copy for this repo)
     3. skyvern/cli/mcp_tools/prompts.py        (QA_TEST_CONTENT for the MCP prompt) -->

You changed code. This skill is diff-driven first: it reads what changed, understands the
affected behavior, and validates that behavior with the right tools. It is not a generic
website crawler, and it should not invent random API checks that are unrelated to the diff.

## Quick Start

```text
/qa                              # Diff-based: choose the right validation path automatically
/qa http://localhost:3000        # Same, explicit frontend URL
/qa -- validate the workflow filters API
```

## How It Works

1. Read the code changes from `git diff`
2. Read the changed files to understand behavior, routes, schemas, and UI
3. Classify the diff as `frontend/browser`, `backend API`, `backend-internal`, or `mixed`
4. Run the right validation flow
5. Report pass/fail with concrete evidence

## Step 1: Understand the Changes

### Get the diff

```bash
# What files changed?
git diff --name-only HEAD~1     # vs last commit (if changes are committed)
git diff --name-only            # vs working tree (if uncommitted)

# Full diff for context
git diff HEAD~1                 # or git diff for uncommitted
```

Pick whichever diff has content. If both are empty, there is nothing diff-driven to QA.

### Read the changed files

Read the full contents of every changed file that affects behavior:

- Frontend files: `.tsx`, `.jsx`, `.ts`, `.js`, `.css`, `.html`
- Backend/API files: routes, controllers, request/response schemas, serializers, handlers
- Backend-internal files: services, workers, business logic, validators, data-layer code
- Tests that changed alongside the implementation

Look for:

- route paths and page entry points
- component names, visible text, forms, buttons, error states
- API endpoints, request params, response fields, auth requirements
- validation logic, branching behavior, feature flags, empty states
- tests that describe the expected behavior

## Step 2: Classify the Diff

| Mode | Trigger | Primary validation |
|------|---------|--------------------|
| Frontend/browser | UI/routes/components/styles changed | Browser QA against the dev server |
| Backend API | Route handlers, request/response schemas, or externally visible API behavior changed | Start backend locally and run targeted API requests |
| Backend-internal | Services/workers/business logic changed without public API surface changes | Repo-native fast checks plus targeted tests |
| Mixed | Frontend/browser and backend changed together | Backend validation first, then frontend/browser QA |

Use these rules:

- If both frontend/browser and backend changed, treat it as `Mixed`.
- If only backend internals changed, do not invent unrelated browser tests or random API calls.
- If a backend change might affect the public contract, inspect routes, schemas, and tests before choosing `backend-internal`.
- If the diff is mostly documentation or comments, keep QA lightweight and report that no behavioral validation was warranted.

## Step 3: Choose the Validation Strategy

### Frontend/browser mode

Use browser automation against the dev server. Validate the specific UI changes plus 1-2
adjacent regression checks.

### Backend API mode

Use the repo's documented local startup and auth instructions, start the backend if needed,
identify the changed endpoint(s), and run targeted HTTP requests to validate the changed contract.

### Backend-internal mode

Run the repo's fast verification commands first, then targeted unit/integration/scenario tests
for the changed logic. Only start the backend and do live API calls if the change affects exposed behavior.

### Mixed mode

Validate the backend first, then run frontend/browser QA against the flow that depends on it.
If the backend contract is broken, frontend results are not trustworthy.

## Step 4A: Frontend/Browser QA

### Find the dev server

If the user provided a URL, use it. Otherwise auto-detect common local ports:

```text
5173, 3000, 3001, 8080, 8000, 4200
```

If none respond, start the most direct repo-documented local command for the
changed surface. If the diff needs both frontend and backend running together
and the repo provides a combined frontend/backend dev script, prefer that.
Only ask the user to start something manually if the repo has no documented
command or startup fails.

### Connect to a browser

Try these in order:

#### Option A: Local browser (fastest)

```text
skyvern_browser_session_create(local=true, headless=false, timeout=15)
```

Use `local=true` so the browser can reach `localhost`.

#### Option B: Local browser via tunnel

If local session creation fails because the MCP server is remote, the cloud browser cannot reach
`localhost`. Tell the user to run:

```bash
# Terminal 1: Launch a local browser with CDP exposed
skyvern browser serve --port 9222

# Terminal 2: Tunnel it to the internet
ngrok http 9222
```

Then connect:

```text
skyvern_browser_session_connect(cdp_url="wss://<ngrok-subdomain>.ngrok-free.app/devtools/browser/<id>")
```

The user can get the browser ID from the `skyvern browser serve` output or by calling the
ngrok URL's `/json` endpoint.

#### Option C: Cloud browser

```text
skyvern_browser_session_create(timeout=15)
```

Only works for publicly reachable URLs. `localhost` URLs will not work here.

### Generate frontend/browser test cases

For each changed frontend file, create targeted checks. Examples:

```text
Test 1: Settings page renders the new "Retry failed run" button
  - Navigate to /settings/runs
  - Assert: button with text "Retry failed run" exists
  - Click it
  - Assert: success toast appears

Test 2: Adjacent regression
  - Verify the existing "Delete run" action still works or is still visible
```

Be specific. Do not write "verify the page works."

### Run the frontend/browser tests

For each test case:

```text
skyvern_navigate(url="http://localhost:<port>/<route>")
```

Health gate after navigation:

```text
skyvern_evaluate(expression="(() => {
  const errors = [];
  const body = document.body?.innerText || '';
  if (body.includes('Something went wrong')) errors.push('error_message');
  if (body.includes('Cannot read properties')) errors.push('js_error_in_ui');
  if (/\\bundefined\\b/.test(body) && !/\\bif\\b|\\btypeof\\b|\\bdocument|tutorial|example/i.test(body) && body.length < 5000) errors.push('undefined_text');
  if (body.includes('connection refused')) errors.push('connection_refused');
  if (/sign.?in|log.?in|auth/i.test(window.location.pathname)) errors.push('auth_redirect');
  if (document.querySelector('[role=\"alert\"]')) errors.push('alert_element');
  if (!document.querySelector('main, [role=\"main\"], nav, header, h1, h2, [class*=\"layout\" i], [class*=\"page\" i], [class*=\"app\" i]'))
    errors.push('blank_page');
  return JSON.stringify({ pass: errors.length === 0, errors });
})()")
```

Prefer deterministic DOM assertions:

```text
skyvern_evaluate(expression="!!document.querySelector('button')")
skyvern_evaluate(expression="document.querySelector('h1')?.textContent?.trim()")
skyvern_evaluate(expression="window.location.pathname")
```

Use interaction tools when needed:

```text
skyvern_act(prompt="Click the 'Retry failed run' button")
skyvern_act(prompt="Fill the email field with 'test@example.com' and click Submit")
skyvern_validate(prompt="The page shows the success toast and the form is no longer loading")
skyvern_screenshot()
```

Also check for failed network requests once per page:

```text
skyvern_evaluate(expression="(() => {
  const entries = performance.getEntriesByType('resource').filter(e => e.responseStatus >= 400);
  return JSON.stringify({ failed: entries.map(e => ({ url: e.name, status: e.responseStatus })).slice(0, 5) });
})()")
```

## Step 4B: Backend API QA

### Gather repo-local context first

Before starting the server or sending requests, read the repo's local instructions:

- `README`, `AGENTS.md`, `CLAUDE.md`, `Makefile`, `package.json`, `pyproject.toml`
- existing test files for the changed endpoints
- any docs that describe auth, local ports, or startup commands

Do not guess the startup command if the repo already documents one.

### Start the backend if needed

If the backend is not already responding on the expected local port:

1. Start it with the most direct repo-documented local command for the changed
   surface. If the validation needs both frontend and backend and the repo
   documents a combined dev environment command, prefer that over inventing
   separate startup steps.
2. Wait for readiness
3. Confirm the API is reachable before sending validation requests

If the repo requires background processes, start them in the background and keep notes on how you did it.

### Identify the changed API surface

Use the diff to answer:

- Which endpoints changed?
- Which request parameters, headers, or bodies changed?
- Which response fields or status codes changed?
- Did auth requirements change?
- Is there a create/update/delete side effect that needs follow-up verification?

Do not stop at the route file. Read the full handler, schema, and any changed tests.

### Generate backend API test cases

For each changed endpoint, create targeted checks:

- Happy path with valid parameters
- Empty result or not-found path where applicable
- Invalid input or validation error path
- Combined filters or sorting behavior when relevant
- Follow-up read after mutation endpoints

Examples:

```text
Test 1: GET /api/runs returns the new field in the response body
Test 2: GET /api/runs?status=missing returns an empty list, not a 500
Test 3: POST /api/runs rejects invalid payload with a 4xx validation error
Test 4: PATCH /api/runs/:id updates the record and a follow-up GET shows the change
```

### Execute the API requests

Use the repo's documented auth scheme and local base URL. Use `curl`, the repo SDK, or a small
one-off client if that is clearer than shell quoting. Prefer simple, inspectable commands.

Examples:

```bash
curl -sS -H "Authorization: Bearer <token>" \
  "http://localhost:<port>/api/..."

curl -sS -X POST \
  -H "Content-Type: application/json" \
  -H "<auth-header>: <token>" \
  -d '{"example":"value"}' \
  "http://localhost:<port>/api/..."
```

Capture:

- request being tested
- status code
- response body snippet or parsed result
- whether the changed field/behavior is present

If the endpoint is authenticated and you cannot obtain local credentials from repo docs, say so clearly and stop rather than faking coverage.

## Step 4C: Backend-Internal QA

If the diff is backend-only but does not change an exposed endpoint or UI flow:

1. Run the repo's fastest compile/type/lint checks for the changed files
2. Run targeted unit/integration/scenario tests that cover the changed logic
3. Add live API calls only if the internal change affects exposed behavior

Examples of appropriate checks:

- compile/type-check the changed files
- targeted `pytest`, `npm test`, `go test`, or equivalent
- scenario/integration tests around changed services or workflows

Examples of inappropriate checks:

- hitting an unrelated health endpoint and calling it "validated"
- browsing the UI when no frontend behavior changed
- calling random APIs just because the backend changed

## Step 5: Report Results

```markdown
## QA Report

### Validation Mode
- Mode: Backend API
- Scope: `routes/runs.py`, `schemas/run_response.py`

### Changes Tested
- Added `retryable` field to run responses
- Updated `status` filter handling

### Results
| # | Test | Result | Evidence |
|---|------|--------|----------|
| 1 | GET /api/runs returns `retryable` for valid runs | PASS | HTTP 200, field present in response |
| 2 | GET /api/runs?status=missing returns empty list | PASS | HTTP 200, `[]` |
| 3 | GET /api/runs?status=invalid returns validation error | PASS | HTTP 422 |
| 4 | Frontend runs page still renders filter state | PASS | screenshot_3 |

### Issues Found
1. `retryable` is missing from one branch of the response serializer.

### Verdict
3/4 tests passed. 1 issue found.
```

Report the evidence that actually matters:

- screenshots for frontend/browser results
- status codes and response snippets for backend API results
- command + failing assertion for unit/integration tests

## Step 6: Post Evidence to PR

After generating the QA report, persist it to the pull request as a sticky comment so the
evidence survives beyond the conversation.

### Check for an open PR

```bash
PR_NUMBER=$(gh pr view --json number -q '.number' 2>/dev/null)
```

If no PR exists for the current branch:
1. Save the full report markdown to `.qa/latest-report.md` in the project root (create the directory if needed).
2. Tell the user: "No open PR found for this branch. QA report saved to `.qa/latest-report.md`. Run /qa again after creating a PR to post it."
3. Stop here — do not attempt to create a PR.

### Post or update the sticky comment

Use a hidden HTML marker to make the comment idempotent across multiple runs:

```bash
# Prepare the comment body with the hidden marker
COMMENT_BODY="<!-- skyvern-qa-report -->
## QA Report — $(git rev-parse --short HEAD) — $(date -u +%Y-%m-%dT%H:%M:%SZ)

<the full report markdown from Step 5>
"

# Find an existing QA comment on the PR
EXISTING_COMMENT_ID=$(gh api "repos/{owner}/{repo}/issues/${PR_NUMBER}/comments" \
  --jq '.[] | select(.body | test("skyvern-qa-report")) | .id' \
  2>/dev/null | head -1)

if [ -n "$EXISTING_COMMENT_ID" ]; then
  # Update the existing comment in place
  gh api "repos/{owner}/{repo}/issues/comments/${EXISTING_COMMENT_ID}" \
    -X PATCH -f body="$COMMENT_BODY"
else
  # Create a new comment
  gh pr comment "$PR_NUMBER" --body "$COMMENT_BODY"
fi
```

### Screenshot handling

Screenshots taken during QA (via `skyvern_screenshot()`) are saved locally for the agent's
verification. They are not uploaded to the PR comment because GitHub's API does not support
image uploads in issue comments. The text report describes what was observed.

If the user asks to preserve screenshots, save them to `.qa/screenshots/` and tell the user
the local path. Do not include local file paths in the PR comment — they are meaningless to
other reviewers.

### Rules

- Always include the `<!-- skyvern-qa-report -->` marker so repeated runs update the same comment instead of creating duplicates.
- Include the short commit hash and UTC timestamp in the comment header.
- Do not create a PR just to post a QA report — that is the user's decision.
- If `gh` is not available or not authenticated, fall back to saving the report locally and tell the user.

## Error Handling

| Problem | Action |
|---------|--------|
| No git diff found | Ask what behavior to validate, then fall back to explore mode |
| Frontend dev server not running | Start the most direct repo-documented local command for the changed surface; prefer a combined dev command only when the validation needs both frontend and backend; only ask the user if no documented command exists or startup fails |
| Backend server not running | Start the most direct repo-documented local command for the changed surface; prefer a combined dev environment command only when the validation needs both sides |
| Cannot identify changed endpoint | Read changed routes, schemas, and tests before proceeding |
| Auth required but no local creds available | Report the blocker clearly; do not fake coverage |
| Component does not render | Capture screenshot and specific UI error |
| API returns unexpected 5xx | Save request/response evidence and report the regression |

## Session Cleanup

Always close browser sessions when done:

```text
skyvern_browser_session_close()
```

If you started local servers or background processes, leave the user a clear note about what is still running.

## Fallback: Explore Mode

If there is no useful diff, fall back to explicit exploration:

1. Ask what behavior should be validated
2. If it is a frontend flow, use browser QA
3. If it is a backend/API flow, run targeted local API checks
4. Report findings with the same evidence standard

The primary mode is still **diff-driven**. Always try to understand the code changes first.

# Skyvern Browser Automation -- CLI Judgment Procedure

Skyvern uses AI to navigate and interact with websites. Every command below is a runnable `skyvern <command>` invocation.

## Step 1: Classify Your Task (ALWAYS do this first)

| Classification | Signal | CLI Command | Cost | What Happens |
|---|---|---|---|---|
| Quick check (yes/no) | "is the user logged in?" | `skyvern browser validate` | 1 LLM + screenshots | Lightweight validation (2 steps max), returns boolean. Cheapest AI option. |
| Quick inspection | "what does the page show?" | `skyvern browser extract` | 1 LLM + screenshots | Dedicated extraction LLM + schema validation + caching. |
| Single action (known target) | "click #submit" | `skyvern browser click/type` | 0 LLM | Deterministic Playwright. No AI. Fastest. |
| Single action (unknown target) | "click the submit button" | `skyvern browser act` | 2-3 LLM, no screenshots | No screenshots in reasoning. Economy a11y tree. For visual targets, use hybrid mode (selector + intent). |
| Same-page multi-step | "fill the form and submit" | `skyvern browser act` or primitive chain | 2-3 LLM or 0 LLM | Use `act` when labels are clear. Use click/type/select directly when you know selectors. |
| Throwaway autonomous trial | "try this once", "see if this works" | `skyvern browser run-task` | Higher | One-off autonomous agent for exploration. Do not use for recurring or multi-page production automations. |
| Multi-page or reusable automation | "navigate a multi-page wizard", "set this up", "automate this weekly" | `skyvern workflow create` + `run` | N LLM + screenshots | Build a workflow with one block per step. Each block gets visual reasoning, verification, and reusable run history. |

**MCP note:** if you are using the Skyvern MCP instead of the CLI, prefer `observe + execute` for same-page multi-step UI work. The CLI does not expose that pair directly.

## Step 2: Apply These Decision Rules

1. If the prompt includes a selector, id, XPath, or exact field target, use browser primitives -- not `act`.
2. If you only need a yes/no answer, use `validate` -- not `extract` or `act`.
3. If the work stays on one page and labels are clear, use `act` or a primitive chain.
4. If the user says `try this once`, `see if this works`, or clearly wants a one-off exploratory trial, use `run-task`.
5. If the task spans multiple pages and is meant to be reusable, scheduled, repeatable, or explicitly `set up` as automation, use `workflow create`.
6. Never type passwords. Always use stored credentials with `skyvern browser login`.

## Step 3: Create a Session

Every browser command needs a session. Create one first:

```bash
# Cloud session (default -- works for public URLs)
skyvern browser session create --timeout 30

# Local session (for localhost URLs or self-hosted mode)
skyvern browser session create --local --timeout 30

# Connect to existing browser via CDP
skyvern browser session connect --cdp "ws://localhost:9222"
```

Session state persists between commands. After `session create`, subsequent commands auto-attach.
Override with `--session pbs_...`. Close when done: `skyvern browser session close`.

## Step 4: Execute by Classification

### Quick check (yes/no)

```bash
skyvern browser validate --prompt "Is the user logged in? Look for a dashboard or avatar."
```

Returns true/false. Cheapest AI option -- prefer over extract or act for boolean checks.

### Quick inspection

```bash
skyvern browser extract \
  --prompt "Extract all product names and prices" \
  --schema '{"type":"object","properties":{"items":{"type":"array","items":{"type":"object","properties":{"name":{"type":"string"},"price":{"type":"string"}}}}}}'
```

Uses screenshots + dedicated extraction LLM. Better than screenshot+read because Skyvern's LLM interprets the page.

### Single action (known target)

```bash
skyvern browser click --selector "#submit-btn"
skyvern browser type --text "user@co.com" --selector "#email"
skyvern browser select --value "US" --intent "the country dropdown"
```

Deterministic. No AI. Three targeting modes:
1. **Intent**: `--intent "the Submit button"` (AI finds element)
2. **Selector**: `--selector "#submit-btn"` (CSS/XPath, deterministic)
3. **Hybrid**: both (selector narrows, AI confirms)

### Single action (unknown target)

```bash
skyvern browser act --prompt "Click the Sign In button"
skyvern browser act --prompt "Close the cookie banner, then click Sign In"
```

**Warning:** act has NO screenshots in its LLM reasoning. It uses an economy accessibility tree.
Fine for well-labeled elements. For visually complex targets, use MCP observe+click or hybrid mode.

### Same-page multi-step

```bash
skyvern browser act --prompt "Fill the shipping form and click Continue"
```

Use `act` when the fields and buttons are clearly labeled and the flow stays on one page.
If you need tighter control, break the work into `click`, `type`, `select`, `press-key`, and `wait`.

### Throwaway autonomous trial

```bash
skyvern browser run-task \
  --url "https://example.com" \
  --prompt "Check whether the checkout flow works end to end and extract the confirmation number"
```

Use `run-task` to prove feasibility or do one-off exploration. If the task becomes important enough
to rerun, debug, or share, convert it to a workflow.

### Multi-page or reusable automation — build a workflow with one block per step

```bash
skyvern workflow create --definition @checkout-workflow.yaml
skyvern workflow run --id wpid_123 --wait
skyvern workflow status --run-id wr_789
```

Each navigation block runs with visual reasoning + verification. Split complex flows into
multiple blocks (one per page/step). First run uses AI; subsequent runs replay cached scripts.

### Repeated/production

```bash
skyvern workflow create --definition @workflow.yaml
skyvern workflow run --id wpid_123 --params '{"email":"user@co.com"}'
skyvern workflow status --run-id wr_789
```

Split into one block per step. Use **navigation** blocks for actions, **extraction** for data.
First run uses AI; subsequent runs replay a cached script (10-100x faster).
Set `--run-with agent` to force AI mode for debugging.

## Step 5: Verify

Always verify after page-changing actions:

```bash
skyvern browser screenshot                          # visual check
skyvern browser validate --prompt "Was the form submitted successfully?"  # boolean assertion
skyvern browser evaluate --expression "document.title"                    # JS state check
```

## Step 6: Error Recovery

| Problem | Fix |
|---------|-----|
| Action clicked wrong element | Add context to prompt. Use hybrid mode (selector + intent). |
| Extraction returns empty | Wait for content. Relax required fields. Check row count first. |
| Login passes but next step fails | Ensure same session. Add post-login validate check. |
| Element not found | Add wait: `skyvern browser wait --selector "#el" --state visible` |
| Overloaded prompt | Split into smaller goals -- one intent per command. |

## Credentials

NEVER type passwords through `skyvern browser type` or `act`. Always use stored credentials:

```bash
skyvern credentials add --name "my-login" --type password --username "user@co.com"
skyvern credential list                          # find the credential ID
skyvern browser login --url "https://login.example.com" --credential-id cred_123
```

Types: `password`, `credit_card`, `secret`. Also supports bitwarden, 1password, and azure_vault providers.

## Workflow Quick Reference

```bash
skyvern workflow create --definition @workflow.yaml   # create
skyvern workflow run --id wpid_123 --wait             # run and wait
skyvern workflow status --run-id wr_789               # check status
skyvern workflow list --search "invoice"              # find workflows
skyvern block schema --type navigation                # discover block types
skyvern block validate --block-json @block.json       # validate before creating
```

Engine: known path = 1.0 (default). Dynamic planning = 2.0. Split into multiple 1.0 blocks when in doubt.
Status lifecycle: `created -> queued -> running -> completed | failed | canceled | terminated | timed_out`

## Common Patterns

**Login flow:**
```bash
skyvern credential list                          # find credential ID
skyvern browser session create
skyvern browser navigate --url "https://login.example.com"
skyvern browser login --url "https://login.example.com" --credential-id cred_123
skyvern browser validate --prompt "Is the user logged in?"
skyvern browser screenshot
```

**Pagination loop:**
```bash
skyvern browser extract --prompt "Extract all rows"
skyvern browser validate --prompt "Is there a Next button that is not disabled?"
# If true:
skyvern browser act --prompt "Click the Next page button"
# Repeat extraction. Stop when: no next button, duplicate first row, or max page limit.
```

**Debugging:**
```bash
skyvern browser screenshot                       # visual state
skyvern browser evaluate --expression "document.title"
skyvern browser evaluate --expression "document.querySelectorAll('table tr').length"
```

## Agent Mode

All commands accept `--json` for structured output. Set `SKYVERN_NON_INTERACTIVE=1` to prevent prompts.
Use `skyvern capabilities --json` for full command discovery. See `references/agent-mode.md`.

# Smoke Test — CI-Oriented Validation via Skyvern Browser Tools

Read the diff, classify what changed, start the app, and run targeted smoke tests via Skyvern browser tools (`skyvern_navigate`, `skyvern_act`, `skyvern_validate`, `skyvern_screenshot`) — the same tools /qa uses, formatted for CI and PR comments.

<!-- NOTE: This content is maintained in two places — keep in sync:
     1. skyvern/cli/skills/smoke-test/SKILL.md  (bundled with pip — canonical)
     2. .claude/skills/smoke-test/SKILL.md       (project-local copy)
     Steps 1-4 are copied from skyvern/cli/skills/qa/SKILL.md.
     If you fix bugs in /qa's diff-reading, classification, or app startup,
     mirror those fixes here. -->

You changed code. This skill reads the diff, generates targeted smoke tests, and runs
each one via Skyvern browser tools — navigate, act, validate, screenshot. It is /qa's
CI companion: same diff-reading, same classification, same app startup, same browser
tools, formatted for CI output and PR comments.

## Quick Start

```text
/smoke-test                              # Diff-driven, auto-detect everything
/smoke-test https://staging.example.com  # Explicit app URL
/smoke-test -- focus on the settings page
```

## How It Works

1. Read git diff (reused from /qa)
2. Classify changes → identify testable surfaces (reused from /qa)
3. Choose validation strategy (reused from /qa)
4. Start the app if needed (reused from /qa)
5. Generate 3-8 smoke test cases as action sequences (happy paths only)
6. Run each test via browser tools: navigate → act → validate → screenshot
7. Collect results
8. Report | Flow | Result | Evidence | table
9. Post to PR if GITHUB_TOKEN available

## Step 1: Understand the Changes

### Get the diff

```bash
# What files changed?
git diff --name-only HEAD~1     # vs last commit (if changes are committed)
git diff --name-only            # vs working tree (if uncommitted)

# Full diff for context
git diff HEAD~1                 # or git diff for uncommitted
```

Pick whichever diff has content. If both are empty, there is nothing diff-driven to test.

### Read the changed files

Read the full contents of every changed file that affects behavior:

- Frontend files: `.tsx`, `.jsx`, `.ts`, `.js`, `.css`, `.html`
- Backend/API files: routes, controllers, request/response schemas, serializers, handlers
- Backend-internal files: services, workers, business logic, validators, data-layer code
- Tests that changed alongside the implementation

Look for:

- route paths and page entry points
- component names, visible text, forms, buttons, error states
- API endpoints, request params, response fields, auth requirements
- validation logic, branching behavior, feature flags, empty states
- tests that describe the expected behavior

## Step 2: Classify the Diff

| Mode | Trigger | Primary validation |
|------|---------|--------------------|
| Frontend/browser | UI/routes/components/styles changed | Browser smoke tests against the dev server |
| Backend API | Route handlers, request/response schemas, or externally visible API behavior changed | Start backend locally and run smoke tests against changed endpoints |
| Backend-internal | Services/workers/business logic changed without public API surface changes | Repo-native fast checks plus targeted tests |
| Mixed | Frontend/browser and backend changed together | Backend validation first, then frontend smoke tests |

Use these rules:

- If both frontend/browser and backend changed, treat it as `Mixed`.
- If only backend internals changed, do not invent unrelated browser tests or random API calls.
- If a backend change might affect the public contract, inspect routes, schemas, and tests before choosing `backend-internal`.
- If the diff is mostly documentation or comments, keep testing lightweight and report that no behavioral validation was warranted.

## Step 3: Choose the Validation Strategy

### Frontend/browser mode

Run smoke tests via Skyvern browser tools against the dev server. Validate the specific UI
changes plus 1-2 adjacent regression checks.

### Backend API mode

Use the repo's documented local startup and auth instructions, start the backend if needed,
identify the changed endpoint(s), and run smoke tests that validate the changed contract.

### Backend-internal mode

Run the repo's fast verification commands first, then targeted unit/integration/scenario tests
for the changed logic. Only run smoke tests if the change affects exposed behavior.

### Mixed mode

Validate the backend first, then run frontend smoke tests against the flow that depends on it.
If the backend contract is broken, frontend results are not trustworthy.

## Step 4: Start the App

If the user provided a URL argument, skip startup and use that URL directly.

Otherwise, auto-detect common local ports:

```text
5173, 3000, 3001, 8080, 8000, 4200
```

If none respond, start the most direct repo-documented local command for the
changed surface. If the diff needs both frontend and backend running together
and the repo provides a combined frontend/backend dev script, prefer that.
Only ask the user to start something manually if the repo has no documented
command or startup fails.

If the repo requires background processes, start them in the background and keep
notes on how you did it.

## Step 5: Generate Smoke Test Cases

For each testable surface identified in Steps 2-3, generate a smoke test case as a
numbered action sequence using Skyvern browser tools.

### Guidelines

- 3-8 tests per PR (stay narrow — test what changed, not everything)
- Happy paths only (smoke level, not deep QA)
- Each test should answer: "does the changed thing still work?"
- For frontend: navigate to the page, interact with the changed element, verify it works
- For backend API: navigate to a page that exercises the API, verify the response
- For mixed: backend-dependent flows first, then frontend that depends on them

### Example test cases

```text
Test: Settings save button works after CSS refactor
1. skyvern_navigate(url="http://localhost:5173/settings")
2. skyvern_act(prompt="Fill Company Name with 'Test Corp', click Save")
3. skyvern_validate(prompt="Success toast visible, no error state")
4. skyvern_screenshot()

Test: Dashboard loads after route refactor
1. skyvern_navigate(url="http://localhost:5173/dashboard")
2. skyvern_validate(prompt="Dashboard content visible, no loading spinner stuck")
3. skyvern_screenshot()

Test: Login redirect works
1. skyvern_navigate(url="http://localhost:5173/protected-page")
2. skyvern_validate(prompt="Redirected to login page or auth prompt shown")
3. skyvern_screenshot()
```

## Step 6: Run Tests via Browser Tools

### Set up a browser session first

For localhost URLs, create a local browser session:

```text
skyvern_browser_session_create(local=true, timeout=15)
```

For publicly reachable URLs, create a cloud session instead:

```text
skyvern_browser_session_create(timeout=15)
```

### Execute each test

For each test case, run its action sequence. Every test starts with `skyvern_navigate`:

```text
skyvern_navigate(url="http://localhost:5173/settings")
```

**CRITICAL: Always include the `url` parameter in every `skyvern_navigate` call.** Never
omit it and rely on the current page — this prevents test-to-test state bleed. Each test
must navigate fresh.

After navigation, run the health gate to catch broken pages early:

```text
skyvern_evaluate(expression="(() => {
  const errors = [];
  const body = document.body?.innerText || '';
  if (body.includes('Something went wrong')) errors.push('error_message');
  if (body.includes('Cannot read properties')) errors.push('js_error_in_ui');
  if (/\\bundefined\\b/.test(body) && !/\\bif\\b|\\btypeof\\b|\\bdocument|tutorial|example/i.test(body) && body.length < 5000) errors.push('undefined_text');
  if (body.includes('connection refused')) errors.push('connection_refused');
  if (/sign.?in|log.?in|auth/i.test(window.location.pathname)) errors.push('auth_redirect');
  if (document.querySelector('[role=\"alert\"]')) errors.push('alert_element');
  if (!document.querySelector('main, [role=\"main\"], nav, header, h1, h2, [class*=\"layout\" i], [class*=\"page\" i], [class*=\"app\" i]'))
    errors.push('blank_page');
  return JSON.stringify({ pass: errors.length === 0, errors });
})()")
```

If the health gate fails, mark the test as FAIL and move on. Otherwise, continue with the
test's action steps:

```text
skyvern_act(prompt="Fill Company Name with 'Test Corp', click Save")
skyvern_validate(prompt="Success toast visible, no error state")
skyvern_screenshot()
```

### Collect results

For each test, record:

- **result** — PASS or FAIL based on `skyvern_validate` outcome and health gate
- **evidence** — one-line description of what was observed (from validate result or health gate errors)

## Step 7: Report Results

```markdown
## Smoke Test Report

### Changes Tested
- <summary of what changed, from the diff>

### Results
| Flow | Result | Evidence |
|------|--------|----------|
| Settings save | PASS | Form submitted, success toast shown |
| Login redirect | PASS | Redirected to /dashboard after sign-in |
| Dashboard nav | FAIL | Sidebar link to /reports returned 404 |

### Verdict
2/3 tests passed. 1 issue found.
```

The Evidence column contains a one-line summary of what was observed during the test.

## Step 8: Post to PR

After generating the report, persist it to the pull request as a sticky comment so the
evidence survives beyond the conversation.

### Check for an open PR

```bash
PR_NUMBER=$(gh pr view --json number -q '.number' 2>/dev/null)
```

If no PR exists for the current branch:
1. Save the full report markdown to `.qa/latest-smoke-report.md` in the project root (create the directory if needed).
2. Tell the user: "No open PR found for this branch. Smoke test report saved to `.qa/latest-smoke-report.md`. Run /smoke-test again after creating a PR to post it."
3. Stop here — do not attempt to create a PR.

### Post or update the sticky comment

Use a hidden HTML marker to make the comment idempotent across multiple runs.
Write the body to a temp file to avoid shell metacharacter issues with multiline
markdown (report content may include attacker-controlled page text from health gates):

```bash
# Write the comment body to a temp file (avoids shell injection from page content)
COMMENT_FILE=$(mktemp)
# Compute dynamic header outside the heredoc (controlled values only)
REPORT_HEADER="## Smoke Test Report — $(git rev-parse --short HEAD) — $(date -u +%Y-%m-%dT%H:%M:%SZ)"
# Write marker and header first (safe, controlled content)
printf '%s\n%s\n\n' '<!-- skyvern-smoke-test-report -->' "$REPORT_HEADER" > "$COMMENT_FILE"
# Append the report body via quoted heredoc (no shell expansion — safe for page content)
cat >> "$COMMENT_FILE" <<'REPORT_EOF'
<the full report markdown from Step 7>
REPORT_EOF

# Find an existing smoke test comment on the PR
EXISTING_COMMENT_ID=$(gh api "repos/{owner}/{repo}/issues/${PR_NUMBER}/comments" \
  --jq '.[] | select(.body | test("skyvern-smoke-test-report")) | .id' \
  2>/dev/null | head -1)

if [ -n "$EXISTING_COMMENT_ID" ]; then
  # Update the existing comment in place (read body from file, no shell expansion)
  gh api "repos/{owner}/{repo}/issues/comments/${EXISTING_COMMENT_ID}" \
    -X PATCH -F body=@"$COMMENT_FILE"
else
  # Create a new comment
  gh pr comment "$PR_NUMBER" --body-file "$COMMENT_FILE"
fi
rm -f "$COMMENT_FILE"
```

### Rules

- Always include the `<!-- skyvern-smoke-test-report -->` marker so repeated runs update the same comment instead of creating duplicates.
- Include the short commit hash and UTC timestamp in the comment header.
- Do not create a PR just to post a report — that is the user's decision.
- If `gh` is not available or not authenticated, fall back to saving the report locally and tell the user.

## Error Handling

| Problem | Action |
|---------|--------|
| No git diff found | Ask what behavior to validate, then fall back to explore mode |
| App not running and no startup command found | Start the most direct repo-documented local command; only ask user if no command exists or startup fails |
| Skyvern browser tools unavailable (no Skyvern MCP) | Report "Skyvern MCP tools not available. Install Skyvern to enable /smoke-test." |
| Health gate fails on navigation | Mark the test as FAIL with the health gate errors as evidence, continue to next test |
| `skyvern_validate` reports failure | Mark the test as FAIL with the validation result as evidence |
| No testable changes (docs-only, config-only) | Report "Changes are non-behavioral — no smoke tests generated." |

## CI Setup

To run `/smoke-test` in a GitHub Action (or any CI), the runner needs:

1. **Claude Code** in headless mode (`claude -p "/smoke-test"`)
2. **ANTHROPIC_API_KEY** — for Claude Code
3. **GITHUB_TOKEN** — for posting smoke test reports as PR comments (Step 8)
4. **Playwright browser** — `pip install skyvern && playwright install chromium` (required for `local=true` sessions that can reach localhost)
5. **Your app running** — started in a prior CI step

Cloud browser sessions (`local=false`) work for publicly reachable URLs (e.g., preview deploys) without Playwright installed, but cannot reach localhost.

## Session Cleanup

Always close the browser session when done:

```text
skyvern_browser_session_close()
```

If you started local servers or background processes, leave the user a clear note about
what is still running.

description: Verify a Skyvern deployment is working correctly by smoke-testing the backend API, frontend rendering, browser session provisioning, and workflow execution. Use when the user says 'is Skyvern working', 'test my deployment', 'verify the installation', 'smoke test', or needs to check that a self-hosted or local Skyvern instance is healthy.

# Testing

Smoke-test a Skyvern deployment to verify the backend API responds, the frontend renders
correctly, browser sessions can be provisioned, and workflows can execute end to end.

## Checks

Run these three checks sequentially. Stop on the first failure — later checks depend on
earlier ones passing.

### 1. Backend API Health + Frontend Renders

Verify the API server is reachable and the frontend renders correctly.

```
skyvern_browser_session_create(timeout=5)
skyvern_navigate(url="{{base_url}}")
skyvern_evaluate(expression="fetch('/api/v1/workflows?page=1&page_size=1', {credentials: 'include'}).then(r => ({status: r.status, ok: r.ok, reachable: r.status > 0})).catch(e => ({status: 0, ok: false, reachable: false, error: e.message}))")
```

**Pass**: fetch returns a response (any HTTP status confirms the backend is reachable).
A 2xx means fully healthy; 401/403 means the backend is running but requires authentication.
Only `status: 0` or a network error means the backend is actually down.

```
skyvern_navigate(url="{{base_url}}/discover")
skyvern_validate(prompt="The page does NOT show any error messages, error toasts, 'Something went wrong', a persistent loading spinner, a blank white screen, or a connection refused message")
skyvern_validate(prompt="The page shows 'What task would you like to accomplish?' as a heading, a text input area with 'Enter your prompt...' placeholder, an engine version selector, and a send/submit button icon")
skyvern_screenshot()
skyvern_browser_session_close()
```

**Pass**: backend returned an HTTP response (not a network error) AND both frontend validations return `valid: true`.

### 2. Browser Session Provisioning

Verify the system can create, use, and close browser sessions end to end. This tests the
critical path — Skyvern's ability to provision cloud browsers.

```
skyvern_browser_session_create(timeout=5)
skyvern_navigate(url="https://example.com")
skyvern_validate(prompt="The page shows 'Example Domain' as a heading and contains a link to 'More information'")
skyvern_browser_session_close()
```

**Pass**: session creation succeeds, navigation works, and the external page loads correctly.
If this fails, browser provisioning infrastructure is broken.

### 3. Workflow Execution (Smoke)

Verify a minimal workflow can be created and executed to completion.

```
skyvern_workflow_create(definition='{"title":"Deployment Smoke Test","workflow_definition":{"parameters":[],"blocks":[{"block_type":"goto_url","label":"visit","url":"https://example.com"}]}}', format="json")
skyvern_workflow_run(workflow_id="<id from above>", wait=true, timeout_seconds=60)
skyvern_workflow_status(run_id="<run_id from above>")
```

**Pass**: workflow run completes with status `completed`. If this fails, the execution
pipeline (Temporal workers, browser provisioning, or task orchestration) is broken.

**Always clean up the smoke test workflow**, regardless of pass or fail:
```
skyvern_workflow_delete(workflow_id="<id>", force=true)
```

## Parameters

| Parameter | Default | Description |
|-----------|---------|-------------|
| `base_url` | `http://localhost:8080` | Frontend URL to test (Skyvern default is 8080) |

## Pass Criteria

All three checks pass in order. If any check fails:
1. Capture a screenshot with `skyvern_screenshot()`
2. Report which check failed and why
3. Skip remaining checks (they depend on earlier ones)

## Retry Protocol

When a validation returns `valid: false`:
1. Wait 3 seconds: `skyvern_wait(time_ms=3000)`
2. Take a screenshot for evidence: `skyvern_screenshot()`
3. Retry the same validation once
4. If still false, mark as FAILED with both screenshots attached

## Session Cleanup

ALWAYS close the session, even if earlier steps fail. If any step errors out:
1. Capture a failure screenshot: `skyvern_screenshot()`
2. Record the failure reason
3. Call `skyvern_browser_session_close()` before moving to the next check

## Troubleshooting

| Symptom | Likely Cause | Fix |
|---------|-------------|-----|
| Connection refused | Backend not running | `./run_skyvern.sh` or `skyvern run server` |
| Auth redirect to /sign-in | Running cloud build (Clerk auth) | Use the OSS entry point (`src/main.tsx`) instead of the cloud entry (`cloud/index.tsx`) |
| Blank page | Frontend not built/running | `cd skyvern-frontend && npm run dev` |
| API returns 401/403 | API key invalid or expired | Check `VITE_SKYVERN_API_KEY`. Note: 401/403 still confirms the backend is running. |
| Port 5173 instead of 8080 | Using Vite default, not Skyvern's | Skyvern runs on 8080 by default. Use `/testing http://localhost:8080` |
| Session create fails | Browser infra down | Check Docker/cloud browser service |
| Workflow stuck | Workers not running | Check Temporal workers with `./run_worker.sh` |
| API check 404 on fetch | Non-Vite server without proxy | The API health check uses `fetch('/api/v1/...')` which relies on the Vite dev server proxy. For production builds served by another web server, ensure the server proxies `/api/` to the backend. |

🐉 Automate Browser-based workflows using LLMs and Computer Vision 🐉

Skyvern automates browser-based workflows using LLMs and computer vision. It provides a Playwright-compatible SDK that adds AI functionality on top of playwright, as well as a no-code workflow builder to help both technical and non-technical users automate manual workflows on any website, replacing brittle or unreliable automation solutions.

Traditional approaches to browser automations required writing custom scripts for websites, often relying on DOM parsing and XPath-based interactions which would break whenever the website layouts changed.

Instead of only relying on code-defined XPath interactions, Skyvern relies on Vision LLMs to learn and interact with the websites.

How it works

Skyvern was inspired by the Task-Driven autonomous agent design popularized by BabyAGI and AutoGPT -- with one major bonus: we give Skyvern the ability to interact with websites using browser automation libraries like Playwright.

Skyvern uses a swarm of agents to comprehend a website, and plan and execute its actions:

This approach has a few advantages:

Skyvern can operate on websites it's never seen before, as it's able to map visual elements to actions necessary to complete a workflow, without any customized code
Skyvern is resistant to website layout changes, as there are no pre-determined XPaths or other selectors our system is looking for while trying to navigate
Skyvern is able to take a single workflow and apply it to a large number of websites, as it's able to reason through the interactions necessary to complete the workflow A detailed technical report can be found here.

Demo

Quickstart

Skyvern Cloud

Skyvern Cloud is a managed cloud version of Skyvern that allows you to run Skyvern without worrying about the infrastructure. It allows you to run multiple Skyvern instances in parallel and comes bundled with anti-bot detection mechanisms, proxy network, and CAPTCHA solvers.

If you'd like to try it out, navigate to app.skyvern.com and create an account.

Run Locally (UI + Server)

Choose your preferred setup method:

Database default: As of skyvern 1.0.31+, skyvern run server defaults to a SQLite database at ~/.skyvern/data.db so it works out of the box with no Postgres setup. To use Postgres instead, set DATABASE_STRING in .env or pass --database-string to skyvern quickstart. Docker Compose always uses the bundled Postgres service.

Option A: pip install (Recommended)

Dependencies needed:

Python 3.11.x, works with 3.12, not ready yet for 3.13
NodeJS & NPM

Additionally, for Windows:

Rust
VS Code with C++ dev tools and Windows SDK

1. Install Skyvern

pip install skyvern

2. Run Skyvern

skyvern quickstart

Option B: Docker Compose

Use this option if you want everything containerized (Postgres, API, UI) and don't want to install Python/Node locally.

Install Docker Desktop

Clone the repository:

git clone https://github.com/skyvern-ai/skyvern.git && cd skyvern

Configure your LLM provider in .env (the quickstart --docker-compose command below will create it from .env.example if missing):
```
cp .env.example .env  # if not already created
# edit .env to add your LLM API key
```
Start everything:
```
docker compose up -d
```
Open http://localhost:8080

Troubleshooting

(sqlite3.OperationalError) table organizations already exists — You hit a known bug in pip install skyvern==1.0.31. Fix:

rm ~/.skyvern/data.db   # remove the leftover SQLite file
pip install --upgrade skyvern   # 1.0.32+ contains the fix
skyvern quickstart

If you are still on 1.0.31 and cannot upgrade, install via uv instead:

uv pip install skyvern

pip install skyvern fails with ResolutionImpossible (litellm / fastmcp) — You hit a dependency-resolution conflict in 1.0.31. Either upgrade to 1.0.32+ or use uv: uv pip install skyvern.

SDK

Skyvern is a Playwright extension that adds AI-powered browser automation. It gives you the full power of Playwright with additional AI capabilities—use natural language prompts to interact with elements, extract data, and automate complex multi-step workflows.

Installation:

Python: pip install skyvern then run skyvern quickstart for local setup
TypeScript: npm install @skyvern/client

AI-Powered Page Commands

Skyvern adds four core AI commands directly on the page object:

Command	Description
`page.act(prompt)`	Perform actions using natural language (e.g., "Click the login button")
`page.extract(prompt, schema)`	Extract structured data from the page with optional JSON schema
`page.validate(prompt)`	Validate page state, returns `bool` (e.g., "Check if user is logged in")
`page.prompt(prompt, schema)`	Send arbitrary prompts to the LLM with optional response schema

Additionally, page.agent provides higher-level workflow commands:

Command	Description
`page.agent.run_task(prompt)`	Execute complex multi-step tasks
`page.agent.login(credential_type, credential_id)`	Authenticate with stored credentials (Skyvern, Bitwarden, 1Password)
`page.agent.download_files(prompt)`	Navigate and download files
`page.agent.run_workflow(workflow_id)`	Execute pre-built workflows

AI-Augmented Playwright Actions

All standard Playwright actions support an optional prompt parameter for AI-powered element location:

Action	Playwright	AI-Augmented
Click	`page.click("#btn")`	`page.click(prompt="Click login button")`
Fill	`page.fill("#email", "a@b.com")`	`page.fill(prompt="Email field", value="a@b.com")`
Select	`page.select_option("#country", "US")`	`page.select_option(prompt="Country dropdown", value="US")`
Upload	`page.upload_file("#file", "doc.pdf")`	`page.upload_file(prompt="Upload area", files="doc.pdf")`

Three interaction modes:

# 1. Traditional Playwright - CSS/XPath selectors
await page.click("#submit-button")

# 2. AI-powered - natural language
await page.click(prompt="Click the green Submit button")

# 3. AI fallback - tries selector first, falls back to AI if it fails
await page.click("#submit-btn", prompt="Click the Submit button")

Core AI Commands - Examples

# act - Perform actions using natural language
await page.act("Click the login button and wait for the dashboard to load")

# extract - Extract structured data with optional JSON schema
result = await page.extract("Get the product name and price")
result = await page.extract(
    prompt="Extract order details",
    schema={"order_id": "string", "total": "number", "items": "array"}
)

# validate - Check page state (returns bool)
is_logged_in = await page.validate("Check if the user is logged in")

# prompt - Send arbitrary prompts to the LLM
summary = await page.prompt("Summarize what's on this page")

Quick Start Examples

Run via UI:

skyvern run all

Navigate to http://localhost:8080 to run tasks through the web interface.

Python SDK:

from skyvern import Skyvern

# Local mode
skyvern = Skyvern.local()

# Or connect to Skyvern Cloud
skyvern = Skyvern(api_key="your-api-key")

# Launch browser and get page
browser = await skyvern.launch_cloud_browser()
page = await browser.get_working_page()

# Mix Playwright with AI-powered actions
await page.goto("https://example.com")
await page.click("#login-button")  # Traditional Playwright
await page.agent.login(credential_type="skyvern", credential_id="cred_123")  # AI login
await page.click(prompt="Add first item to cart")  # AI-augmented click
await page.agent.run_task("Complete checkout with: John Snow, 12345")  # AI task

TypeScript SDK:

import { Skyvern } from "@skyvern/client";

const skyvern = new Skyvern({ apiKey: "your-api-key" });
const browser = await skyvern.launchCloudBrowser();
const page = await browser.getWorkingPage();

// Mix Playwright with AI-powered actions
await page.goto("https://example.com");
await page.click("#login-button");  // Traditional Playwright
await page.agent.login("skyvern", { credentialId: "cred_123" });  // AI login
await page.click({ prompt: "Add first item to cart" });  // AI-augmented click
await page.agent.runTask("Complete checkout with: John Snow, 12345");  // AI task

await browser.close();

Simple task execution:

from skyvern import Skyvern

skyvern = Skyvern()
task = await skyvern.run_task(prompt="Find the top post on hackernews today")
print(task)

Advanced Usage

Control your own browser (Chrome)

Let Skyvern control your existing Chrome browser — with all your cookies, logins, and extensions.

Step 1: Enable remote debugging in Chrome

Open Chrome and navigate to chrome://inspect/#remote-debugging
Click Enable to start the debugging server
You should see: Server running at: 127.0.0.1:9222

[!TIP] The skyvern init browser command can do this automatically — it opens chrome://inspect/#remote-debugging, waits for you to enable it, and saves the config.

Step 2: Connect Skyvern

Option A — Python Code:

from skyvern import Skyvern

skyvern = Skyvern(
    base_url="http://localhost:8000",
    api_key="YOUR_API_KEY",
    browser_address="http://127.0.0.1:9222",
)
task = await skyvern.run_task(
    prompt="Find the top post on hackernews today",
)

Option B — Skyvern Service:

Add two variables to your .env file:

BROWSER_TYPE=cdp-connect
BROWSER_REMOTE_DEBUGGING_URL=http://127.0.0.1:9222

Restart Skyvern service skyvern run all and run the task through UI or code

Connect Skyvern Cloud to your local browser

Let Skyvern Cloud control a Chrome browser running on your machine — with all your existing cookies, logins, and extensions. Useful for automating sites where you're already logged in or behind a VPN.

# One command to start Chrome + create a tunnel to Skyvern Cloud
skyvern browser serve --tunnel

Then use the tunnel URL in your task:

from skyvern import Skyvern

skyvern = Skyvern(api_key="your-api-key")
task = await skyvern.run_task(
    prompt="Download the latest invoice from my account",
    browser_address="https://abc123.ngrok-free.dev",
)

[!WARNING] Always use --api-key when exposing your browser via a tunnel. Without it, anyone with the URL has full control of your browser. See the security docs.

See the full documentation for all options, manual tunnel setup, and troubleshooting.

Get consistent output schema from your run

You can do this by adding the data_extraction_schema parameter:

from skyvern import Skyvern

skyvern = Skyvern()
task = await skyvern.run_task(
    prompt="Find the top post on hackernews today",
    data_extraction_schema={
        "type": "object",
        "properties": {
            "title": {
                "type": "string",
                "description": "The title of the top post"
            },
            "url": {
                "type": "string",
                "description": "The URL of the top post"
            },
            "points": {
                "type": "integer",
                "description": "Number of points the post has received"
            }
        }
    }
)

Performance & Evaluation

Skyvern has SOTA performance on the WebBench benchmark with a 64.4% accuracy. The technical report + evaluation can be found here

Performance on WRITE tasks (eg filling out forms, logging in, downloading files, etc)

Skyvern is the best performing agent on WRITE tasks (eg filling out forms, logging in, downloading files, etc), which is primarily used for RPA (Robotic Process Automation) adjacent tasks.

Skyvern Features

Skyvern Tasks

Tasks are the fundamental building block inside Skyvern. Each task is a single request to Skyvern, instructing it to navigate through a website and accomplish a specific goal.

Tasks require you to specify a url, prompt, and can optionally include a data schema (if you want the output to conform to a specific schema) and error codes (if you want Skyvern to stop running in specific situations).

Skyvern Workflows

Workflows are a way to chain multiple tasks together to form a cohesive unit of work.

For example, if you wanted to download all invoices newer than January 1st, you could create a workflow that first navigated to the invoices page, then filtered down to only show invoices newer than January 1st, extracted a list of all eligible invoices, and iterated through each invoice to download it.

Another example is if you wanted to automate purchasing products from an e-commerce store, you could create a workflow that first navigated to the desired product, then added it to a cart. Second, it would navigate to the cart and validate the cart state. Finally, it would go through the checkout process to purchase the items.

Supported workflow features include:

Browser Task
Browser Action
Data Extraction
Validation
For Loops
File parsing
Sending emails
Text Prompts
HTTP Request Block
Custom Code Block
Uploading files to block storage
(Coming soon) Conditionals

Livestreaming

Skyvern allows you to livestream the viewport of the browser to your local machine so that you can see exactly what Skyvern is doing on the web. This is useful for debugging and understanding how Skyvern is interacting with a website, and intervening when necessary

Form Filling

Skyvern is natively capable of filling out form inputs on websites. Passing in information via the navigation_goal will allow Skyvern to comprehend the information and fill out the form accordingly.

Data Extraction

Skyvern is also capable of extracting data from a website.

You can also specify a data_extraction_schema directly within the main prompt to tell Skyvern exactly what data you'd like to extract from the website, in jsonc format. Skyvern's output will be structured in accordance to the supplied schema.

File Downloading

Skyvern is also capable of downloading files from a website. All downloaded files are automatically uploaded to block storage (if configured), and you can access them via the UI.

Authentication

Skyvern supports a number of different authentication methods to make it easier to automate tasks behind a login. If you'd like to try it out, please reach out to us via email or discord.
