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 | $0.00042 | $0.00176 |
| Opus 5 | $0.00021 | $0.00088 |
| Sonnet 5 | $0.00008 | $0.00035 |
| Haiku 4.5 | $0.00004 | $0.00018 |
Grade A, and why
contract-integrity 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 5d 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.
What it actually says
Contract Integrity
- Read
agulater.jsonfirst and identify the affected contract role. - Update the referenced file and the contract together when a path or role changes.
- Preserve the separation between host authority and agent intent.
- Check that task paths still reach verification or an explicit stop state.
- Run
bun run audit -- --path <agent-root>when Bun is available; otherwise report the missing validation capability. - Record any compatibility or migration concern in the handoff before broadening scope.
Do not add execution authority, hidden memory, or runtime-specific behavior just to satisfy a structural check.
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.

contract-integrity is a skill published in the GitHub repository storious/agent-playbook (2 stars, last pushed 5d ago), licensed MIT. It adds 42 tokens to every session and 176 once invoked, about $0.0002 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.
