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 | $0.00056 | $0.00629 |
| Opus 5 | $0.00028 | $0.00315 |
| Sonnet 5 | $0.00011 | $0.00126 |
| Haiku 4.5 | $0.00006 | $0.00063 |
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 4d 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
95% 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.
How it starts
The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Language
Keep user's language by default. User write Portuguese → reply Portuguese caveman. 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):
export CAVEMAN_DEFAULT_MODE=ultra
Config file (~/.config/caveman/config.json macOS/Linux, %APPDATA%\caveman\config.json Windows):
{ "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 ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

extract-entities
Extract people, organizations, dates, amounts, or custom labels from a document through the connected Superlinked MCP edge, returning a compact table instead of reading the full document into context. Use when the user asks to list, extract, or tabulate entities from a file.
parse-document
Convert a PDF, scan, image of a page, or office file to clean markdown through the connected Superlinked MCP edge, so the source document is not read into model context directly. Use when the user asks to read, parse, OCR, extract from, summarize, or answer questions about a document.
redact-pii
Redact personal data from a document through the connected Superlinked MCP edge before working with the content. Use when the user asks to redact, anonymize, scrub, de-identify, or remove PII/sensitive data from a document.
summarize-document
Summarize a long PDF, scan, office file, text file, or markdown file through the connected Superlinked MCP edge instead of reading the whole source into model context. Use when the user asks for a summary, overview, digest, or "what does this document say" about a large file.
superlinked-docs
Offload document, image, and structured-output work to the Superlinked inference cluster: convert PDF/DOCX/PPTX/XLSX/HTML/scans to clean markdown, describe an image (caption + tags), or produce schema/grammar-constrained JSON off the cluster — instead of ingesting the file directly, which can reduce the tokens billed…
gno
Search local documents, files, notes, and knowledge bases. Index directories, search with BM25/vector/hybrid, get AI answers with citations. Use when user wants to search files, find documents, query notes, look up information in local folders, index a directory, set up document search, build a knowledge base, needs…
