Based on SOC occupation classification
Runtime debugging loop, reproduce, form ranked hypotheses, instrument, fix, verify. Use for crashes, wrong output, intermittent failures, race conditions, or anything that works locally but not in prod. Triggers: "debug this", "why is this failing at runtime", "intermittent failure", "race condition", "works locally but not in prod", "flaky test", "silent failure". NOT for build failures, type errors, or toolchain issues; those belong to the hephaestus flow. This skill owns runtime misbehavior only.
Strip AI-generated code slop from changed files: double-guards, dead fallbacks, redundant re-validation, narrating comments, speculative flexibility, premature abstraction, and more. Each category pairs with a KEEP rule and a trust-boundary proof requirement, so cleanup never strips load-bearing validation or error handling. Triggers: 'remove ai slop', 'clean up generated code', 'de-slop', 'remove defensive clutter', 'strip ai slop', 'clean up ai-generated code'.
Designer-turned-developer who crafts stunning UI/UX even without design mockups. Use for UI components, styling, layout, animations, and visual design work.
MUST USE for ANY git operations. Atomic commits, rebase/squash, history search (blame, bisect, log -S). Triggers: 'commit', 'rebase', 'squash', 'who wrote', 'when was X added', 'find the commit that'.

Fix the following build issue: $ARGUMENTS
No issue specified → run the build command to discover failures, then diagnose and fix.
Hephaestus workflow: reproduce, diagnose root cause, minimal fix, verify build passes. Repeat until exit 0.
After build passes, record evidence:
evidence_log(evidence_type="build", command="<build command>", exit_code=0, output_snippet="<relevant output>")
