Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.00564 |
| Opus 5 | $0.00028 | $0.00282 |
| Sonnet 5 | $0.00011 | $0.00113 |
| Haiku 4.5 | $0.00006 | $0.00056 |
Grade A, and why
caveman-help scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to caveman-help — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
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
| Mode | Trigger | What change |
|---|---|---|
| Lite | /caveman lite |
Drop filler. Keep sentence structure. |
| Full | /caveman |
Drop articles, filler, pleasantries, hedging. Fragments OK. Default. |
| Ultra | /caveman ultra |
Extreme compression. Bare fragments. Tables over prose. |
| Wenyan-Lite | /caveman wenyan-lite |
Classical Chinese style, light compression. |
| Wenyan-Full | /caveman wenyan |
Full 文言文. Maximum classical terseness. |
| Wenyan-Ultra | /caveman wenyan-ultra |
Extreme. Ancient scholar on a budget. |
Mode stick until changed or session end.
Skills
| Skill | Trigger | What it do |
|---|---|---|
| caveman-commit | /caveman-commit |
Terse commit messages. Conventional Commits. ≤50 char subject. |
| caveman-review | /caveman-review |
One-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-help |
This card. |
Deactivate
Say "stop caveman" or "normal mode". Resume anytime with /caveman.
Configure Default Mode
Default mode = full. Change it:
Environment variable (highest priority):
export CAVEMAN_DEFAULT_MODE=ultra
Config file (~/.config/caveman/config.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.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
