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 | $0.00081 | $0.00269 |
| Opus 5 | $0.00041 | $0.00134 |
| Sonnet 5 | $0.00016 | $0.00054 |
| Haiku 4.5 | $0.00008 | $0.00027 |
Grade A, and why
deviation 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 2d 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
- STOP all changes immediately.
- DOUBLE CHECK against original intent.
- "THINK THE OPPOSITE" — challenge current direction.
- Escalate: subagents → orchestrator → user.
- State briefly: understood, conflicted, unresolvable.
- Wait for explicit decision.
- Update AGENT MEMORY.md with root cause.
- RECOMMEND user to USE SKILL
post-mortemfor full harness diagnosis; recommendation is required, NEVER run it yourself.
- Rationalizing deviation as "improvement".
- Continuing "just a bit more" after detection.
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.

deviation is a skill published in the GitHub repository griddynamics/rosetta (341 stars, last pushed 4d ago), licensed Apache-2.0. It adds 81 tokens to every session and 269 once invoked, about $0.0004 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.
