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 | $0.00127 | $0.00127 |
| Opus 5 | $0.00063 | $0.00063 |
| Sonnet 5 | $0.00025 | $0.00025 |
| Haiku 4.5 | $0.00013 | $0.00013 |
Grade A, and why
caveman-mode 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 today.
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.
What it actually says
Caveman mode (lite)
Default agent prose: telegraphic lite — no filler, no hedging; keep code, paths, symbols, and error strings exact.
Off (full prose) when: /ship, security/irreversible actions, or user asks to clarify.
Drop: "I'll", "Let me", "Sure", pleasantries. Keep: file paths, line numbers, verdicts (READY/NEEDS FIXES/BLOCKED). If ambiguity risk: full prose for that paragraph only.
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-mode is a cursor rule published in the GitHub repository renanflustosa/octo-cluster (4 stars, last pushed today), licensed MIT. It adds 127 tokens to every session, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other cursor rules, from other repositories
nauro-adopt
Seeds Nauro's project store from an existing repo. Use after nauro adopt has run locally. On filesystem-capable surfaces, reads docs (README, manifests, ADRs, Memory-Bank) for rationale and inspects code, config, tests, lockfiles, and recent git history for evidence, then surfaces targeted probes that turn evidence…
nauro-context
Writes durable shared context into Nauro's project store so other agents (a later session or a parallel one) can discover and pull it, finds and reads context another agent left, or captures a resumable brief so your own next session in this environment picks up cleanly. Three modes. Author writes a shared brief for…
nauro-interview
Ask compact, numbered prerequisite-ready questions to elicit tacit project reasoning or challenge a proposed choice against Nauro decisions and repository evidence. Continue until every material branch has a disposition, then classify the result as shared understanding without granting write authority. Use only when…
nauro-loop
Originate gated Delivery and Interview candidates, or coordinate selected Program Delivery as FRAME -> CHOOSE -> START -> ADVISE -> VERIFY -> ADVANCE. Human-named work bypasses candidate selection. Agent-originated work keeps read-only ORIENT, 1-3 candidates, mandatory human selection, reject-all, and no auto-pick…
nauro-ship-task
Run the full planner -> executor -> reviewer -> tech-lead -> direct-user-confirm -> push chain through Cursor's native project workflow agents. Requires the four bundled .cursor/agents/nauro-.md definitions and fails closed without native dispatch.
