surgical-patch skill
Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.

Surgical patch
Reproduce failure first when economical; otherwise capture strongest available evidence.
- Trace symptom to responsible mechanism.
- Change narrowest layer that owns incorrect behavior.
- Preserve unrelated behavior and user changes.
- Avoid cleanup, renaming, and abstraction outside fix.
- Add only regression proof relevant to task.
Run focused proof plus nearest affected gate. Stop when failure is fixed and regression proof passes.

- Acaveman-commitWrite a Conventional Commits message compressed to intent only. Use for "write a commit", "commit message", /commit or /caveman-commit.
- Ccaveman-compressCompress a memory file such as CLAUDE.md or a todo list into caveman format to save input tokens, keeping a readable backup. Sends the file's text to the configured model provider. Trigger: /caveman-compress.

- Acaveman-discoverFind and label every LLM workflow in the repository so Caveman Cloud groups spend by workflow instead of one bucket. Use for "discover workflows" or breaking LLM spend down by workflow.
- Acaveman-evidence-reviewRead-only review of Caveman Cloud evidence: cost, Cave Score, workflows, traces, latency, errors, routing, savings. Use when asked what Caveman found or where LLM spend goes.
- Acaveman-exploreRead-only repository explorer for cold-start orientation, broad cross-file localization, or when a direct search failed. Skip it when the exact file or symbol is already named. Returns path:line citations only; its reads stay out of main context.
- Acaveman-helpQuick-reference card for the three caveman skills and their commands. Trigger: /caveman-help or "caveman help".
- Acaveman-learnAct on a Caveman learn report - review the ranked token sinks, apply cost-lowering fixes with per-edit consent, and report what those fixes returned. Use when asked to lower an agent's token cost, what caveman has saved, to trim a heavy CLAUDE.md, or to offload re-pasted context into cavemem.
