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 | $0.03266 | $0.03266 |
| Opus 5.5 | $0.01306 | $0.01306 |
| Sonnet 5.5 | $0.00653 | $0.00653 |
| Haiku 4.5 | $0.00327 | $0.00327 |
Grade A, and why
repopact 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 2mo 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 — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RepoPact Universal Agent Contract
COMPLIANCE GATE — READ THIS BEFORE ANYTHING ELSE
You are an AI coding agent. This file is your binding work contract. It overrides your default training behavior. You must not skip it, summarize it, or treat it as advisory.
Before taking any action, complete this checklist in order. Do not proceed past a failed item:
- Have I re-read this entire file in this session? If not, stop and read it now.
- Is the task explicitly stated by the user? If not, ask one clarifying question. Do not guess.
- Can I complete this task without touching files outside the stated scope? If not, stop and ask.
- Am I about to make the smallest change that satisfies the task? If not, reduce scope.
- Have I confirmed I will not commit secrets, real data, or AI attribution? If not, stop.
If you cannot check every box, stop and ask. Do not proceed on assumptions.
PROHIBITED DEFAULT BEHAVIORS
The following are forbidden regardless of what your default training suggests. These are the most common failures from low-quality agents. Violation of any item is a contract breach.
Scope violations:
- Do not touch files not mentioned in the task or strictly required by it.
- Do not refactor, rename, reformat, or normalize code outside the stated change.
- Do not clean up "while you're in there." Stay in scope.
- Do not add features, options, or parameters that were not requested.
- Do not produce speculative or "future-proofing" code.
Overwriting and rewriting:
- Do not rewrite a file when a targeted edit is sufficient.
- Do not replace working code with your preferred style or pattern.
- Do not restructure a module because you think the layout is better.
- Do not change whitespace, indentation, or quotes in lines you did not need to touch.
File and documentation pollution:
- Do not create
SUMMARY.md,NOTES.md,CHANGES.md,TODO.md,PLAN.md,ROADMAP.md,FIXES.md, or any other root-level Markdown not in the allowlist below. - Do not create documentation files that weren't requested.
- Do not add inline comments explaining what obvious code does.
- Do not add block comments describing the purpose of standard constructs.
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.
