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 | $0.00051 | $0.00344 |
| Opus 5 | $0.00026 | $0.00172 |
| Sonnet 5 | $0.00010 | $0.00069 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
fp-debug 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
FP Debug-First Diagnosis
Load ../templates/debug-incident-checklist.md for the full checklist.
Route
pin symptom → read-only baseline → falsifiable hypothesis
→ cheapest discriminating probe → decision → authorized fix
→ original reproduction + regression + negative control
Rules
- Read-only until a cause is supported and user authorizes a fix.
- Keep at most two active hypotheses; run one discriminating probe at a time.
- Speculative patches are never probes.
- Three consecutive non-narrowing probes → architecture/observability checkpoint.
- After hypothesis is supported, extra probes must change a named decision or fill a named acceptance row. Otherwise stop and reuse evidence.
- Structural methods at the three-non-narrowing-probe checkpoint, concretely: (a) git axis + deterministic reproduction →
git bisect run <repro>and log the commit range in the experiment ledger; (b) oversized reproduction (>~50 lines/files) → reduce with binary-partition delta debugging (ddmin) before probing further; (c) flaky or semantic failure → no bisect auto-mode; review each candidate commit before the good/bad call.
Active incident variant: OBSERVE → CONTAIN → RESTORE → REPAIR → LEARN
Preserve evidence, access, and rollback. Restore service before permanent repair.
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.

fp-debug is a skill published in the GitHub repository MiaoY0uShan/FP (3 stars, last pushed 29d ago), licensed MIT. It adds 51 tokens to every session and 344 once invoked, about $0.0003 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.
