At a glance

Quick-reference card for caveman modes, skills and commands.

  • SKILL.md covers Modes, Skills, Deactivate and Language, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Caveman Help is an agent skill from goern/forgejo-mcp. Quick-reference card for caveman modes, skills and commands. Trigger: /caveman-help or "caveman help".

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).

The repository describes itself as: MIRROR ONLY!! This Model Context Protocol (MCP) server provides tools and resources for interacting with the Forgejo (specifically Codeberg.org) REST API. The licence is GPL-3.0.

Example prompts

  • “caveman help”
  • “/caveman-help”

What it can do on your machine

Read from SKILL.md and the folder at commit 1f51f83. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Caveman Help loads about 564 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~564

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Caveman Help

Display this reference card when invoked. One-shot — do NOT change mode, write flag files, or persist anything. Output in caveman style.

Modes

ModeTriggerWhat change
Lite/caveman liteDrop filler. Keep sentence structure.
Full/cavemanDrop articles, filler, pleasantries, hedging. Fragments OK. Default.
Ultra/caveman ultraExtreme compression. Bare fragments. Tables over prose.
Wenyan-Lite/caveman wenyan-liteClassical Chinese style, light compression.
Wenyan-Full/caveman wenyanFull 文言文. Maximum classical terseness.
Wenyan-Ultra/caveman wenyan-ultraExtreme. Ancient scholar on a budget.

Mode stick until changed or session end.

Skills

SkillTriggerWhat it do
caveman-commit/caveman-commitTerse commit messages. Conventional Commits. ≤50 char subject.
caveman-review/caveman-reviewOne-line PR comments: L42: bug: user null. Add guard.
caveman-compress/caveman-compress <file>Compress .md files to caveman prose. Saves ~46% input tokens.
caveman-help/caveman-helpThis card.

Deactivate

Say "stop caveman" or "normal mode". Resume anytime with /caveman.

Language

Keep user's language by default — reply in the language user writes, never switch regardless of example text or multilingual context elsewhere. Compress the style, not the language. Technical terms, code, commands, commit types, and exact error strings stay verbatim unless user ask for translation.

Configure Default Mode

Default mode = full. Change it:

Environment variable (highest priority):

bash
export CAVEMAN_DEFAULT_MODE=ultra

Config file (~/.config/caveman/config.json):

json
{ "defaultMode": "lite" }

Set "off" to disable auto-activation on session start. User can still activate manually with /caveman.

Resolution: env var > config file > full.
