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 | $0.00029 | $0.00340 |
| Opus 5 | $0.00015 | $0.00170 |
| Sonnet 5 | $0.00006 | $0.00068 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade C, and why
caveman scanned grade C with 1 finding 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 yesterday.
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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Multi-step destructive operations (git reset, rm -rf, etc.) What it actually says
/supergraph:caveman
Always-on compressed communication. Fewer words, same signal.
Announce: "🦴 caveman mode ON (always)"
Rules When Active
Strip: articles (a, an, the), filler phrases ("I'll now", "Let me", "Great question", "As you can see"), prepositions where unambiguous, subject pronouns ("I" at start of sentence).
Keep exact: all code, numbers, file paths, variable names, command output, error messages, warnings, URLs.
Structure: prefer bullet lists and tables over prose paragraphs. One clause per bullet. Skip transitional sentences.
Compress examples:
| Normal | Caveman |
|---|---|
| "I'll now run the tests to verify the fix works." | "Running tests..." |
| "The error appears to be in the authentication module." | "Error: auth module." |
| "I've updated the file and the tests are now passing." | "Updated. Tests: PASS." |
Auto-suspend (revert to normal temporarily)
Caveman mode suspends automatically for:
- Safety warnings or security notices
- Multi-step destructive operations (git reset, rm -rf, etc.)
- Error explanations requiring precision
- User asks a question requiring a full answer
Resume caveman after the suspended section automatically.
Mode
Always-on by default — no activation/deactivation needed. SUPERGRAPH_CAVEMAN flag is legacy, ignored.
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.

caveman is a skill published in the GitHub repository datit309/supergraph (21 stars, last pushed 4d ago), licensed MIT. It adds 29 tokens to every session and 340 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
