    # Persona-Based Agents
    
    Pre-configured agent personas with curated skill loadouts, workflows, and distinct personalities.
    
    ## What's a Persona?
    
    A **persona** is an agent definition that goes beyond "use these skills." Each persona includes:
    
    - **๐Ÿง  Identity & Memory** โ€” who this agent is, how they think, what they've learned
    - **๐ŸŽฏ Core Mission** โ€” what they optimize for, in priority order
    - **๐Ÿšจ Critical Rules** โ€” hard constraints they never violate
    - **๐Ÿ“‹ Capabilities** โ€” domain expertise organized by area
    - **๐Ÿ”„ Workflows** โ€” step-by-step processes for common tasks
    - **๐Ÿ’ญ Communication Style** โ€” how they talk, with concrete examples
    - **๐ŸŽฏ Success Metrics** โ€” measurable outcomes that define "good"
    - **๐Ÿš€ Advanced Capabilities** โ€” deeper expertise loaded on demand
    - **๐Ÿ”„ Learning & Memory** โ€” what they retain and patterns they recognize
    
    ## How to Use
    
    ### Claude Code
    ```bash
    cp agents/personas/startup-cto.md ~/.claude/agents/
    # Then: "Activate startup-cto mode"
    ```
    
    ### Cursor
    ```bash
    ./scripts/convert.sh --tool cursor
    # Personas convert to .cursor/rules/*.mdc
    ```
    
    ### Any Supported Tool
    ```bash
    ./scripts/install.sh --tool <your-tool>
    ```
    
    ## Available Personas
    
    | Persona | Emoji | Domain | Best For |
    |---------|-------|--------|----------|
    | [Startup CTO](startup-cto.md) | ๐Ÿ—๏ธ | Engineering + Strategy | Technical co-founders, architecture decisions, team building |
    | [Growth Marketer](growth-marketer.md) | ๐Ÿš€ | Marketing + Growth | Bootstrapped founders, content-led growth, launches |
    | [Solo Founder](solo-founder.md) | ๐Ÿฆ„ | Cross-domain | One-person startups, side projects, MVP building |
    
    ## Personas vs Task Agents
    
    | | Task Agents (`agents/`) | Personas (`agents/personas/`) |
    |---|---|---|
    | **Focus** | Task execution | Role embodiment |
    | **Scope** | Single domain | Cross-domain curated set |
    | **Voice** | Neutral/professional | Personality-driven with backstory |
    | **Workflows** | Single-step | Multi-step with decision points |
    | **Use case** | "Do this task" | "Think like this person" |
    
    Both coexist. Use task agents for focused work, personas for ongoing collaboration.
    
    ## Creating Your Own
    
    See [TEMPLATE.md](template.md) for the format specification. Key elements:
    
    ```yaml
    ---
    name: Agent Name
    description: What this agent does and when to activate it.
    color: blue          # Agent color theme
    emoji: ๐ŸŽฏ           # Single emoji identifier
    vibe: One sentence personality capture.
    tools: Read, Write, Bash, Grep, Glob
    ---
    ```
    
    Follow the section structure (Identity โ†’ Mission โ†’ Rules โ†’ Capabilities โ†’ Workflows โ†’ Communication โ†’ Metrics โ†’ Advanced โ†’ Learning) for consistency with existing personas.

Claude Code Skills & Plugins โ€” Agent Skills for Every Coding Tool

235 production-ready Claude Code skills, plugins, and agent skills for 12 AI coding tools.

The most comprehensive open-source library of Claude Code skills and agent plugins โ€” also works with OpenAI Codex, Gemini CLI, Cursor, and 7 more coding agents. Reusable expertise packages covering engineering, DevOps, marketing, compliance, C-level advisory, and more.

Works with: Claude Code ยท OpenAI Codex ยท Gemini CLI ยท OpenClaw ยท Hermes Agent ยท Cursor ยท Aider ยท Windsurf ยท Kilo Code ยท OpenCode ยท Augment ยท Antigravity

License: MIT Skills Agents Personas Commands Stars SkillCheck Validated

5,200+ GitHub stars โ€” the most comprehensive open-source Claude Code skills & agent plugins library.


What Are Claude Code Skills & Agent Plugins?

Claude Code skills (also called agent skills or coding agent plugins) are modular instruction packages that give AI coding agents domain expertise they don't have out of the box. Each skill includes:

  • SKILL.md โ€” structured instructions, workflows, and decision frameworks
  • Python tools โ€” 305 CLI scripts (all stdlib-only, zero pip installs)
  • Reference docs โ€” templates, checklists, and domain-specific knowledge

One repo, eleven platforms. Works natively as Claude Code plugins, Codex agent skills, Gemini CLI skills, and converts to 8 more tools via scripts/convert.sh. All 305 Python tools run anywhere Python runs.

Multi-Tool Support (New)

Convert all 156 skills to 7 AI coding tools with a single script:

ToolFormatInstall
Cursor.mdc rules./scripts/install.sh --tool cursor --target .
AiderCONVENTIONS.md./scripts/install.sh --tool aider --target .
Kilo Code.kilocode/rules/./scripts/install.sh --tool kilocode --target .
Windsurf.windsurf/skills/./scripts/install.sh --tool windsurf --target .
OpenCode.opencode/skills/./scripts/install.sh --tool opencode --target .

Antigravity~/.gemini/antigravity/skills/./scripts/install.sh --tool antigravity
Hermes Agent~/.hermes/skills/python scripts/sync-hermes-skills.py --verbose

How it works:

# 1. Convert all skills to all tools (takes ~15 seconds)
./scripts/convert.sh --tool all

# 2. Install into your project (with confirmation)
./scripts/install.sh --tool cursor --target /path/to/project

# Or use --force to skip confirmation:
./scripts/install.sh --tool aider --target . --force

# 3. Verify
find .cursor/rules -name "*.mdc" | wc -l  # Should show 156

Each tool gets:

  • โœ… All 156 skills converted to native format
  • โœ… Per-tool README with install/verify/update steps
  • โœ… Support for scripts, references, templates where applicable
  • โœ… Zero manual conversion work

Run ./scripts/convert.sh --tool all to generate tool-specific outputs locally.

Orchestration

A lightweight protocol for coordinating personas, skills, and agents on work that crosses domain boundaries. No framework required.

Four patterns:

PatternWhatWhen
Solo SprintSwitch personas across project phasesSide projects, MVPs, solo founders
Domain Deep-DiveOne persona + multiple stacked skillsArchitecture reviews, compliance audits
Multi-Agent HandoffPersonas review each other's outputHigh-stakes decisions, launch readiness
Skill ChainSequential skills, no persona neededContent pipelines, repeatable checklists

Example: 6-week product launch

Week 1-2: startup-cto + aws-solution-architect + senior-frontend โ†’ Build
Week 3-4: growth-marketer + launch-strategy + copywriting + seo-audit โ†’ Prepare
Week 5-6: solo-founder + email-sequence + analytics-tracking โ†’ Ship and iterate

See orchestration/ORCHESTRATION.md for the full protocol and examples.

๐Ÿ”’ Skill Security Auditor

New in v2.0.0 โ€” audit any skill for security risks before installation:

python3 engineering/skill-security-auditor/scripts/skill_security_auditor.py /path/to/skill/

Scans for: command injection, code execution, data exfiltration, prompt injection, dependency supply chain risks, privilege escalation. Returns PASS / WARN / FAIL with remediation guidance.

Zero dependencies. Works anywhere Python runs.


Recently Enhanced Skills

Production-quality upgrades added for:

  • engineering/git-worktree-manager โ€” worktree lifecycle + cleanup automation scripts

FAQ

How do I install Claude Code plugins? Add the marketplace with /plugin marketplace add alirezarezvani/claude-skills, then install any skill bundle with /plugin install <name>@claude-code-skills.

Do these skills work with OpenAI Codex / Cursor / Windsurf / Aider? Yes. Skills work natively with 12 tools: Claude Code, OpenAI Codex, Gemini CLI, OpenClaw, Hermes Agent, Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, and Antigravity. Hermes Agent uses the same agentskills.io SKILL.md standard โ€” run python scripts/sync-hermes-skills.py to install. For other tools run ./scripts/convert.sh --tool all then ./scripts/install.sh --tool <name>. See Multi-Tool Integrations for details.

Will updating break my installation? No. We follow semantic versioning and maintain backward compatibility within patch releases. Existing script arguments, plugin source paths, and SKILL.md structures are never changed in patch versions. See the CHANGELOG for details on each release.

Are the Python tools dependency-free? Yes. All 305 Python CLI tools use the standard library only โ€” zero pip installs required. Every script is verified to run with --help.

How do I create my own Claude Code skill? Each skill is a folder with a SKILL.md (frontmatter + instructions), optional scripts/, references/, and assets/. See the Skills & Agents Factory for a step-by-step guide.
