Writing style and tone guide for human-sounding content. Use when writing documentation, READMEs, commit messages, PR descriptions, blog posts, LinkedIn posts, social media content, or any user-facing content.
Executes implementation plans with smart task grouping. Groups related tasks to share context, parallelizes across independent subsystems.
Diagnose and fix tests that pass in isolation but fail when run concurrently. Covers shared state isolation, resource conflicts, and timing-based flakiness.
Guides CI/CD pipeline architecture, security hardening, and deployment strategies for GitHub Actions. Use when designing workflows, securing supply chains, optimizing build performance, configuring deployments, managing infrastructure as code pipelines, or setting up pipeline observability.
Defines product features from a PM perspective before technical planning begins. Use when scoping new features, writing product specs, defining user problems, choosing what to build, researching existing patterns, or bridging the gap between strategy and implementation. Covers JTBD analysis, competitive research, UX/DX experience definition, and scope negotiation for consumer, B2B, and developer tool products.
Writes behavior-focused tests using Testing Trophy model with real dependencies. Use when writing tests, choosing test types, or avoiding anti-patterns like testing mocks.

If 3+ fixes have failed: Stop fixing symptoms. Question the architecture. The bug may be a design problem, not a code problem.
For multi-component systems: Add diagnostic logging at each component boundary before proposing fixes. See references/debugging-techniques.md for instrumentation patterns (binary search, git bisect, minimal reproduction, strategic logging, differential analysis).
For log-heavy investigations: Use Skill(reading-logs) for efficient analysis.
## Root Cause
[1-3 sentences explaining underlying issue]
Located in: `file.ts:123`
## What Was Wrong
[Specific problem - mutation, race condition, missing validation, etc.]
## The Fix
[Changes made and why they address root cause]
## Verification
- [x] Bug reproduced and confirmed fixed
- [x] Existing tests pass
- [x] Added regression test
