Analyzes coupling between modules using the three-dimensional model (strength, distance, volatility) from "Balancing Coupling in Software Design". Use when asking "are these modules too coupled?", "show me dependencies", "analyze integration quality", "which modules should I decouple?", "coupling report", or evaluating architectural health. Do NOT use for domain boundary analysis (use domain-analysis) or component sizing (use component-identification-sizing).
Review and simplify recently changed code for reuse, clarity, and efficiency while preserving behavior. Use when the user asks to simplify, refine, polish, clean up, or make code clearer, after finishing a logical chunk of implementation that should be tightened before commit, or when asked to review changes since a specific commit or branch.
Identify and clean up stale feature flags in a PostHog project. Use when the user wants to find unused, fully rolled out, or abandoned feature flags, review them for safety, and then disable or delete them. Covers staleness detection, dependency checking, and safe removal workflows.
Sweep the current branch for leftovers of an abandoned design after a significant mid-work decision change, and rewrite the affected code, comments, tests, and docs so the result reads as if it had been designed this way from the beginning. Use when the user says "design cleanup", "clean up the old approach", "erase the journey", says a design decision changed and asks to clean up after it, or after a pivot in approach mid-branch. This is a rewrite pass over the code touched by the decision only — not a general refactoring or bug-hunting pass.
Discover large source-file refactor candidates and propose cohesion- and risk-driven split plans using available semantic tooling.
Modular Code Organization
Implement narrowly scoped code changes with focused validation. Use for small bug fixes, tweaks, and features.
Applies software engineering best practices, design principles, and avoids common anti-patterns. Use when designing systems, reviewing code quality, refactoring legacy code, making architectural decisions, or improving maintainability.
Use when given a GitHub issue URL or number to investigate and implement a fix. Triggers on "fix issue", "fix bug", "fix
