pos-debug

Debug composite — reproduce, hypothesize, test, fix with bug pattern memory. Replaces 4 debug skills.

Replaces: debug, unified-debug, systematic-debugging, investigate

Actions

Action	What
diagnose [bug]	Reproduce + hypothesize + test — root cause analysis
fix [finding]	Apply minimum fix for confirmed root cause
verify	Re-run reproduction + regression test after fix

Routing

1. Parse action from first argument
2. Load domain memory from ~/.productionos/domains/pos-debug/
3. If first run: auto-detect project context, create profile
4. Dispatch to sub-skills/{action}.md
5. Score against evaluation/rubric.yml, update memory

Domain Memory

Stored at ~/.productionos/domains/pos-debug/: bug-history.jsonl (past bugs with root causes), patterns.jsonl (recurring bug patterns in this codebase), learnings.jsonl

Inputs

Parameter	Values	Default	Description
action	diagnose, fix, verify	diagnose	Sub-skill to run
target	path, URL, or description	required	What to operate on

Guardrails

1. Memory is append-only. Never delete history.
2. Every action scored against rubric. No silent completion.
3. Profile is user-controlled. Never change without asking.
4. Evidence required. No fabricated metrics.
5. Learn from history. Compare to past executions.
