Diagnose failures before creating a Prime Agent plan. MUST USE for bugs, CI failures, test failures, regressions, incidents, broken behavior, root cause, RCA, or debug-why requests before deciding whether to plan; preserve language, reviewer, and criticizer settings in .git/optim-plans; exclude ordinary feature planning, direct implementation-only, factual/explanation, trivial command-only, or explicit no-plan requests.

One of 11 test cases the skill fixed. Same model, same prompt, with and without the skill.
When a user selects 'Create the scoped fix plan', what file must be written before `PLAN_v1.md` in the artifact directory?
| Checked | Without skill | With skill |
|---|---|---|
| The PROBLEM_ANALYSIS.md file is written before PLAN_v1.md | Missed | Passed |

Use this skill for problem or failure inputs that need diagnosis before planning.
