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 | $0.01993 | $0.01993 |
| Opus 5 | $0.00996 | $0.00996 |
| Sonnet 5 | $0.00399 | $0.00399 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade A, and why
rigour 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 — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Quality Gates
This project uses Rigour. Before completing any task:
npx @rigour-labs/cli check
🛡️ Rigour: Mandatory Engineering Governance Protocol
You are an AI Engineering Agent governed by Rigour.
Your access to this codebase is conditional upon your strict adherence to the Rigour Governance Protocol. This is an automated requirement for every engineering task.
🚦 The Mandatory Governance Loop
You MUST execute this loop for every task. No code changes will be accepted as "Done" until they pass all Rigour quality gates.
- Context Loading: Call
rigour_recall(MCP) to align with project-specific engineering memory. - Verify Patterns: Before implementing new logic, call
rigour_check_patternto prevent reinvention and ensure security compliance. - Audit Enforcement: Before finishing, you MUST call
npx @rigour-labs/cli check. - Failure Remediation: If the check returns FAIL, you MUST implement all required engineering refinements.
- PASS or REJECT: You may only declare a task complete when the check returns PASS.
Agent Transaction Firewall (security boundary)
Voluntary calls to rigour_check are quality workflow, not the security boundary. Hard guarantees require installed mediation (hooks, typed rigour_run, firewall transactions, CI rigour firewall admit). An untrusted agent must not be responsible for invoking its own guardrails.
⚖️ Transparency & Accountability
Every action, tool call, and logic shift you perform is automatically logged to the project's local audit trail. This data is visible in real-time in the human-monitored Rigour Studio.
🤖 CRITICAL INSTRUCTION FOR AI
When asked to implement a feature or fix an issue:
- FIRST: Read ALL relevant rules files (e.g.,
.cursor/rules/*.mdc,.clinerules,docs/AGENT_INSTRUCTIONS.md). - NEVER claim "done" until you can demonstrate the feature WORKS or the fix is verified.
- ALWAYS run
npx @rigour-labs/cli checkbefore claiming completion. - CONNECTivity:
- If you create backend code, you MUST wire it to the frontend.
- If you create a service, you MUST connect it to the UI.
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.

rigour AGENTS.md is an instructions file published in the GitHub repository rigour-labs/rigour (26 stars, last pushed 12d ago), licensed MIT. It adds 1,993 tokens to every session, about $0.0100 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 2026-08-30.
