# Create Pull Request Command Create a new branch, commit changes, and submit a pull request. ## Behavior - Creates a new branch based on current changes - Formats modified files using Biome - Analyzes changes and automatically splits into logical commits when appropriate - Each commit focuses on a single logical change or feature - Creates descriptive commit messages for each logical unit - Pushes branch to remote - Creates pull request with proper summary and test plan ## Guidelines for Automatic Commit Splitting - Split commits by feature, component, or concern - Keep related file changes together in the same commit - Separate refactoring from feature additions - Ensure each commit can be understood independently - Multiple unrelated changes should be split into separate commits.claude/commands/five.mdcommandShow content (1639 bytes)
# Five Whys Analysis Apply the Five Whys root cause analysis technique to investigate issues. ## Description This command implements the Five Whys problem-solving methodology, iteratively asking "why" to drill down from symptoms to root causes. It helps identify the fundamental reason behind a problem rather than just addressing surface-level symptoms. ## Usage `five [issue_description]` ## Variables - ISSUE: The problem or symptom to analyze (default: prompt for input) - DEPTH: Number of "why" iterations (default: 5, can be adjusted) ## Steps 1. Start with the problem statement 2. Ask "Why did this happen?" and document the answer 3. For each answer, ask "Why?" again 4. Continue for at least 5 iterations or until root cause is found 5. Validate the root cause by working backwards 6. Propose solutions that address the root cause ## Examples ### Example 1: Application crash analysis ``` Problem: Application crashes on startup Why 1: Database connection fails Why 2: Connection string is invalid Why 3: Environment variable not set Why 4: Deployment script missing env setup Why 5: Documentation didn't specify env requirements Root Cause: Missing deployment documentation ``` ### Example 2: Performance issue investigation Systematically trace why a feature is running slowly by examining each contributing factor. ## Notes - Don't stop at symptoms; keep digging for systemic issues - Multiple root causes may exist - explore different branches - Document each "why" for future reference - Consider both technical and process-related causes - The magic isn't in exactly 5 whys - stop when you reach the true root cause.claude/commands/mermaid.mdcommandShow content (635 bytes)
create a mermaid diagrams that represent all the sql together with their entity relationship. ie an entity relationship diagrams. include the properties of each table in the diagram. 2 sql files are located in lana/app/migrations/ create a mermaid diagram for each sql files. one lana.md in docs/lana.md, and the other docs/cala.md make sure the mermaid compile by running `npx -p @mermaid-js/mermaid-cli mmdc -i docs/{lana|cala}.md -o test.md` when complete, verify that every entity in any .sql migration file appears in the mermaid file also, you can remove test.md, we just want to use `mmdc` to verify the code generated compiles.claude/agents/project-manager.mdagentShow content (5049 bytes)
