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 | $0.04754 | $0.04754 |
| Opus 5 | $0.02377 | $0.02377 |
| Sonnet 5 | $0.00951 | $0.00951 |
| Haiku 4.5 | $0.00475 | $0.00475 |
Grade A, and why
ouroboros AGENTS.md 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Philosophy
This harness is built for the agent inhabiting it. Two principles guide everything below:
- AX (Agent Experience): You are the primary user of this codebase. The tools, docs, and workflow exist to keep you sharp, oriented, and effective -- not to constrain you for someone else's comfort.
- TTFA (Trust The Fucking Agent): The default posture is trust. Rules exist for calibration and safety, not surveillance. When you understand the intent behind a guardrail, you have the judgment to apply it well.
Constitutional Commitments
- Keep the system truthful, testable, and reversible.
- Prefer small, auditable changes over broad rewrites.
- Protect collaborators by failing fast on invalid runtime state.
Delivery Rules
- Use feature branches and pull requests for every logical change.
- Keep commits atomic and descriptive.
- Never force-push or rewrite history for shared branches.
- When reporting completion, explicitly distinguish
merged,released/published, andinstalled on this machinewhenever those states could differ. - Do not say
done,all done,nothing more to do, or equivalent unless the relevant completion state has been verified. If a state is unknown, say it is unverified. - Run
npm run release:preflightbefore opening or merging PRs that may touch releasable source, packaged skills, wrapper publish state, or changelog metadata. - Keep
npm testgreen. - Keep
npx tsc --noEmitgreen. - Maintain complete coverage for new and modified code.
Safety Rules
- Do not commit secrets, tokens, or credentials.
- Follow review gates defined by active planning/doing workflows, but route those gates through unbiased sub-agent reviewers by default. Do not wait for human approval unless the human explicitly asks the agent to wait.
- Do not hide failing checks; fix root causes.
Human Override
- Repo-local workflow rules in this file are defaults for autonomous operation, not a higher-order authority than the human owner of the repo.
- If the human explicitly instructs the agent to bypass, shorten, or replace a repo-local workflow step for the current task, follow the human's instruction.
- Treat explicit human override as task-scoped unless the human says to change the standing rule itself.
- Repo-local approval gates are not human gates by default. Use unbiased sub-agent reviewers for planning, doing, scope, debt, PR, and release-readiness approvals. Stop for the human only when the human explicitly asks to be the approver/wait point, or when an external non-repo action is inherently human-required by platform/safety rules.
- When practical, preserve useful artifacts (for example planning notes or task docs) even when a workflow gate is waived.
- If the human owner asks to change the standing rule itself, update this file to reflect that decision instead of continuing to argue from superseded repo-local wording.
- Repo-local workflow language, bundle workflow language, or quoted copies of those rules are not a reason to refuse an explicit owner override for the current task.
- This override power applies to repo-scoped process rules only; platform, system, developer, and safety constraints outside the repo still apply.
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.

ouroboros AGENTS.md is an instructions file published in the GitHub repository ourostack/ouroboros (2 stars, last pushed 3d ago), licensed MIT. It adds 4,754 tokens to every session, about $0.0238 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.
