LCS Debug Ext

Use this skill to investigate bugs with evidence first, then produce a report and patch proposal. The agent must not apply code changes.

Core Contract

Create generated artifacts only under .lcs/work-items/<timestamp>-<slug-work-item>-debug-ext/.
Before finishing, ensure .lcs/work-items/<timestamp>-<slug-work-item>-debug-ext/debug.md exists.
Do not write generated output to .lcs/debug/, .aix/, docs/, project root, source files, test files, instruction files, or skill files unless the user explicitly asks in a separate follow-up task.
Do not modify source code, tests, config, docs, or instructions.
Produce only a debug report, evidence summary, reproduction notes, ranked hypotheses, instrumentation suggestions, optional regression-test proposal, and patch proposal.
Clearly state Changes applied: None in the report.
Separate confirmed facts from hypotheses.
Separate patch proposal from applied changes.
Use [TODO] where evidence is missing.
Use [ASK USER] where clarification or a user decision is required.
