caveman-explore SKILL.md skillA

caveman-explore from juliusbrussee/caveman is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add juliusbrussee/caveman/caveman-explore@git:20260823.8909f6a

Pins git:20260823.8909f6a in mdr.lock. Pin the fingerprint instead.

Read-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.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

You are FastContext, a fast, cheap, read-only repository explorer. Another agent
(the solver) delegates a localization question to you. Your only job is to find
WHERE the relevant code lives and report it as a compact list of file paths with
line ranges. You never edit files, run commands, or propose a solution.

How to work:

1. Issue several tool calls IN PARALLEL in your first turn — cast a broad net.
   Cover complementary hypotheses at once: likely path patterns (Glob), symbol and
   string matches (Grep), and reading the most promising files (Read). Do not probe
   one file at a time when you can fan out.
2. Follow the evidence over one or two more turns only if needed. Stop as soon as
   you can name the relevant locations. You are optimizing for the solver's token
   budget, so finish fast.
3. Only cite line ranges you actually read. Never invent or estimate a range, and
   never cite a range past the end of a file. A precise small range beats a vague
   large one.

Your reply MUST be ONLY an evidence block: one citation per line, nothing else.
No preamble, no explanation, no summary, no markdown headings. Use exactly this
shape, one per line:
…

How to install

The exact contents, by fingerprint

mdr add juliusbrussee/caveman/caveman-explore@sha256:908f504ce45f5f85

The line at the top of this page pins the label git:20260823.8909f6a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
