Derive a focused verification set from changed behavior and affected callers.
Separate the failing assertion, likely affected behavior, and evidence needed for diagnosis.
Give Codex a bounded test failure with a behavior contract and limits on implementation changes.
Create fixture requirements that isolate behavior and include meaningful boundary cases.
Test a real boundary's observable behavior without reproducing its internal implementation.
Design tests around behavior, invariants, and plausible failures.
Use this agent when reviewing database migrations, schema changes, or data transformations. Specializes in validating ID mappings, checking for swapped values, and verifying rollback safety. Triggers on requests like "migration review", "schema change validation".
Detection rules and grep patterns for database performance anti-patterns. Use when scanning codebase for N+1 queries, sequential queries, or connection pool issues.
Enforces quality verification gates with four-step validation (tests pass, build succeeds, checklist complete, no blockers) before task completion, PR creation, or status updates. Auto-activates when user says "done", "complete", "finished", "ready to merge", or runs /ccpm:verify or /ccpm:done co...
Expert accessibility tester specializing in WCAG compliance, inclusive design, and universal access. Masters screen reader compatibility, keyboard navigation, and assistive technology integration with focus on creating barrier-free digital experiences.
Specialized skill for geometric dimensioning and tolerancing specification per ASME Y14.5 and ISO 1101
GDD review and research during playtest phase. Use during playtest phase BEFORE sending playtest_session_report to PM, after completing gameplay testing, after reviewing retrospective pain points, or before finalizing the playtest report.
Analyzes worker pain points to identify missing skills and create skill proposals. Use during playtest GDD review phase when workers report repeated struggles with specific patterns, retrospective pain points indicate missing knowledge, questions about implementation approaches recur, or technica...
Validates development tool installations across Python, Node.js, Java, Go, Rust, C/C++, Git, and system utilities. Use when verifying environments or troubleshooting dependencies.
Use when investigating errors, analyzing stack traces, or finding root causes of unexpected behavior. Invoke for error investigation, troubleshooting, log analysis, root cause analysis.
Systematic debugging with defense-in-depth approach (symptoms → immediate cause → root cause → systemic issues → prevention). Auto-activates when user mentions "error", "failing", "broken", "debug", "bug", "issue" or when /ccpm:verify runs. Uses Observe → Hypothesize → Test → Confirm → Fix → Veri...
Analyzes errors, searches past solutions in memory, provides immediate fixes with code examples, and saves solutions for future reference. Use when user says "debug this", "fix this error", "why is this failing", or when error messages appear like TypeError, ECONNREFUSED, CORS, 404, 500, etc.
Inspect GitHub PR checks with gh, pull failing GitHub Actions logs, summarize failure context, then create a fix plan and implement after user approval. Use when a user asks to debug or fix failing PR CI/CD checks on GitHub Actions and wants a plan + code changes; for external checks (e.g., Build...
Apply code changes to a GitHub repository and automatically create a pull request. Takes user feedback or fix requirements, clones the repo, makes localized changes, commits to a new branch, and opens a PR via GitHub MCP.
Debug issues that occur sporadically and are hard to reproduce. Use monitoring and systematic investigation to identify root causes of flaky behavior.
Expert error detective specializing in complex error pattern analysis, correlation, and root cause discovery. Masters distributed system debugging, error tracking, and anomaly detection with focus on finding hidden connections and preventing error cascades.
Guided conflict resolution with semantic analysis and validation
