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 | $0.00028 | $0.00129 |
| Opus 5 | $0.00014 | $0.00064 |
| Sonnet 5 | $0.00006 | $0.00026 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
conformance-loop 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
Conformance loop
- Define the capability and stable project corpus.
- Run Fallow and comparison tools with documented equivalent settings.
- Manually verify disagreements against source.
- Classify true positive, false positive, false negative, or model difference.
- Implement one general correction with a regression fixture.
- Re-run the full corpus and retain only net improvements.
- Run
review.
Competitor output is a lead, not ground truth.
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.

conformance-loop is a skill published in the GitHub repository fallow-rs/fallow (4,438 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 129 once invoked, about $0.0001 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.

Use this skill whenever writing or editing Rust //, ///, or //! comments in Biome, including comments added incidentally and end-user rustdoc inside lint/assist declarations. For lint/assist rustdoc, also load lint-rule-development for content requirements. Do not use for formatter handling of comments in user code.
