Use when receiving code review feedback (especially if unclear or technically questionable), when completing tasks or major features requiring review before proceeding, or before making any completion/success claims. Covers three practices - receiving feedback with technical rigor over performative agreement, requesting reviews via code-reviewer subagent, and verification gates requiring evidence before any status claims. Essential for subagent-driven development, pull requests, and preventin...

Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Focuses on recently modified code unless instructed otherwise.

Stage changes and create git commits with conventional commit messages. Use when asked to "commit", "stage and commit", "save changes", or after completing implementation tasks. Alias for /git/cm.

Use when designing database schemas, writing queries and aggregations, optimizing indexes for performance, performing database migrations, configuring replication and sharding, implementing backup and restore strategies, managing database users and permissions, analyzing query performance, or administering production databases.

Systematic debugging framework ensuring root cause investigation before fixes. Includes four-phase debugging process, backward call stack tracing, multi-layer validation, and verification protocols. Use when encountering bugs, test failures, unexpected behavior, performance issues, or before claiming work complete. Prevents random fixes, masks over symptoms, and false completion claims.

Use when the user asks to enhance documentation, add code comments, create API docs, improve technical documentation, or document code. Triggers on keywords like "document", "documentation", "API docs", "comments", "JSDoc", "XML comments", "explain code".

Use AFTER any code changes (feature implementation, bug fix, refactor) to enforce mandatory dual-pass review. First pass reviews unstaged changes for correctness and convention compliance. Second pass ONLY executes if first pass made any corrections. Ensures work follows project conventions, development rules, and best practices before task completion.
