Install
Skills CLI
npx skills add JuliusBrussee/caveman
Asks which skills and agents to install. Just one: npx skills add JuliusBrussee/caveman --skill cavecrew — add -g for every project.
Claude Code
git clone https://github.com/JuliusBrussee/cavemancp -r "caveman/skills/cavecrew" ~/.claude/skills/
Copies the cavecrew skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add JuliusBrussee/caveman
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
cavecrew
When to delegate to `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit) or `cavecrew-reviewer` (diff review) instead of working inline or using `Explore`. Their output is compressed, so main context lasts longer.
skills/cavecrew/SKILL.md on GitHub (opens in a new tab) -
caveman-commit
Write a Conventional Commits message compressed to intent only. Use for "write a commit", "commit message", /commit or /caveman-commit.
skills/caveman-commit/SKILL.md on GitHub (opens in a new tab) -
caveman-compress
Compress a memory file such as CLAUDE.md or a todo list into caveman format to save input tokens, keeping a readable backup. Trigger: /caveman-compress.
skills/caveman-compress/SKILL.md on GitHub (opens in a new tab) -
caveman-discover
Find 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.
skills/caveman-discover/SKILL.md on GitHub (opens in a new tab) -
caveman-evidence-review
Read-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.
skills/caveman-evidence-review/SKILL.md on GitHub (opens in a new tab) -
caveman-explore
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.
skills/caveman-explore/SKILL.md on GitHub (opens in a new tab) -
caveman-help
Quick-reference card for caveman modes, skills and commands. Trigger: /caveman-help or "caveman help".
skills/caveman-help/SKILL.md on GitHub (opens in a new tab) -
caveman-learn
Act 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.
skills/caveman-learn/SKILL.md on GitHub (opens in a new tab) -
caveman-manage
Inspect Caveman Cloud's experiment lifecycle and block unsafe execution. Use when asked to start, approve, cancel, promote or roll back a Caveman experiment.
skills/caveman-manage/SKILL.md on GitHub (opens in a new tab) -
caveman-optimize
Turn a Caveman optimization observation into an operator-chosen candidate with a paired baseline evaluation. Use when asked to inspect or evaluate a Caveman optimization report. Needs explicit approval.
skills/caveman-optimize/SKILL.md on GitHub (opens in a new tab) -
caveman-review
Compressed code review - one line per finding with location, problem and fix. Use for /caveman-review, "review this PR", or "review the diff".
skills/caveman-review/SKILL.md on GitHub (opens in a new tab) -
caveman-setup
Wire a repository through the Caveman Cloud gateway so every LLM request is measured, with no behavior change. Use for "set up caveman" or adding LLM spend observability.
skills/caveman-setup/SKILL.md on GitHub (opens in a new tab) -
caveman-stats
Show recorded output and cache-read token usage and mode attribution for the current Claude Code session, or locate the host's native usage report. Trigger: /caveman-stats.
skills/caveman-stats/SKILL.md on GitHub (opens in a new tab) -
caveman
Ultra-compressed communication mode that cuts output tokens while keeping technical accuracy. Levels: lite, full, ultra and the wenyan variants. Use for /caveman, "caveman mode", "talk like caveman", "be brief" or "less tokens".
skills/caveman/SKILL.md on GitHub (opens in a new tab) -
investigate-first
Diagnose ambiguous failures before editing. Use for unknown causes, intermittent behavior, performance regressions, or investigations needing evidence-ranked hypotheses.
skills/investigate-first/SKILL.md on GitHub (opens in a new tab) -
lean-build
Build feature work with high overbuilding risk. Use for new behavior, product slices, or integrations where repository reuse, strict scope, and an explicit stop condition matter.
skills/lean-build/SKILL.md on GitHub (opens in a new tab) -
migration
Implement reversible compatibility-safe transitions. Use for schema, data, API, protocol, configuration, or dependency migrations requiring rollback and preservation proof.
skills/migration/SKILL.md on GitHub (opens in a new tab) -
safe-refactor
Restructure code while preserving behavior. Use for extraction, consolidation, ownership moves, or cleanup where verification must bracket structural edits.
skills/safe-refactor/SKILL.md on GitHub (opens in a new tab) -
surgical-patch
Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.
skills/surgical-patch/SKILL.md on GitHub (opens in a new tab) -
verify-and-stop
Prove existing work meets acceptance conditions without expanding scope. Use for validation-only tasks, completion checks, focused gate runs, and last-mile proof.
skills/verify-and-stop/SKILL.md on GitHub (opens in a new tab)
No skill matches that filter.
Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
