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.

What it costs to keep this loaded
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 | $0.00064 | $0.01999 |
| Opus 5 | $0.00032 | $0.01000 |
| Sonnet 5 | $0.00013 | $0.00400 |
| Haiku 4.5 | $0.00006 | $0.00200 |
Grade A, and why
audit-resilience 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.
How it starts
The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.
audit-resilience — The "80% Problem" Non-Functional Audit
Degree of freedom: MIXED — Phases 1 and 4 [HIGH freedom]; Phase 0/2
surface greps [LOW freedom — run exactly].
Agents nail the happy path (CRUD, passing tests) and silently skip what decides whether code survives real traffic: a webhook with no idempotency key double-charges; a fetch with no timeout hangs the request; a retry storm with no backoff takes down the dependency; PII lands in plaintext logs. This audit finds those gaps before production does.
Read-only. This skill inventories resilience gaps and hands each to the right fix skill. It does not change code.
How to reason
- Observe — quote the call/mutation and whether timeout, retry+jitter, or idempotency key exists
- Interpret — hang, retry storm, double-write, or silent catch?
- Classify — Implemented / Partial / Missing (per matrix row)
- Severity — payment/webhook without idempotency, or no timeout on a live path = Critical
Worked example
Observe:
POST /api/webhooks/stripeinserts a payment with noIdempotency-Key/ dedupe (app/api/webhooks/stripe/route.ts:44);fetchto Stripe has nosignal/ timeout. Interpret: Stripe retry double-charges; a hung fetch exhausts the pool. Classify: idempotency Missing; timeout Missing. Severity: Critical. Finding: webhook | no idempotency + no timeout | Critical |backend-patterns
Phase 0 — Detect the surfaces [LOW freedom — run exactly]

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.

audit-resilience is a skill published in the GitHub repository kensaurus/cursor-kenji (9 stars, last pushed 11d ago), licensed MIT. It adds 64 tokens to every session and 1,999 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 2026-09-03.
