Manages deprecation and migration. Use when removing old systems, APIs, or features. Use when migrating users from one implementation to another. Use when deciding whether to maintain or sunset existing code.
Safely remove a feature flag from code while preserving production behavior. Use when the user wants to remove a flag from code, delete flag references, or create a PR that hardcodes the winning variation after a rollout is complete.
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.
PR quality checklist for ensuring comprehensive, well-documented pull requests. Use before submitting PRs to improve review efficiency and code quality.
Prevent semantic code duplication with capability index and check-before-write
Define and manage coding standards in docs/rules/code/. Use when creating TypeScript rules, naming conventions, error handling patterns, architecture standards, or any code-related enforceable rules.
Intelligent code cleanup with mainline detection, stale artifact discovery, and safe execution. Supports targeted cleanup and confirmation.
Audit a codebase for maintenance and modernization. Challenges scope, reviews architecture/quality/tests/performance/dependencies, files deferred work via bd. Language-specific addendums for iOS/Swift, Go, and Web/JS/CSS activate automatically based on what's in the repo. Supports monorepos with mixed stacks.
Decision Coaching for Vue Component/Composable Refactoring — Users paste a piece of code or point to an SFC, and the skill first performs a diagnosis ("Fat Trunk" / "UI & IO Entanglement" / "Reactivity & Business Logic Entanglement"), then selects one from three recipes, and provides a specific sequence of extraction steps (which variable to move first, what errors the compiler will throw, how to fix them one by one, when rollback is possible). The entire process ensures behavioral equivalence through compiler green lights + step-by-step rollback, without relying on test safeguards. Trigger scenarios: Users say "This Vue component is too fat / I want to extract the logic / Split this SFC / This composable is too messy / Extract a composable / Split into humble / Pure functionalize", or point to an obviously overlong .vue / composable file and request "Refactor / Optimize / Split". Only handles Vue (Vue 2 Options, Vue 2/3 `<script setup>`, composable, pinia store). Does not handle: Adding new features (follow feature process), fixing bugs (follow issue process), cross-module architecture restructuring, backend code.
Bug investigation and fix workflow. Triggers: 'debug', 'fix bug', 'investigate issue', 'something is broken', or /debug. Hotfix track for quick fixes, thorough track for root cause analysis. Do NOT use for feature development or refactoring. Do NOT escalate to /ideate unless the fix requires architectural redesign.
Analyze changes and update WordPress plugin version references safely.
Debug and fix bugs, errors, or unexpected behavior
