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 | $0.00069 | $0.01310 |
| Opus 5 | $0.00034 | $0.00655 |
| Sonnet 5 | $0.00014 | $0.00262 |
| Haiku 4.5 | $0.00007 | $0.00131 |
Grade A, and why
audit-env-parity 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
audit-env-parity — Environments that agree
Degree of freedom: MIXED — Phases 0–1 [HIGH freedom]; Phase 2
three-way name diff [LOW freedom — names only, never values].
Read-only. Find where environments disagree in ways that cause "works on my machine", silent prod misbehavior, or leaked secrets.
The classic outage: a new env var added locally, referenced in code, never set in prod — deploy is green, feature is broken.
Never print secret values. Present the gap matrix; do not change host config until approved.

How to reason
- Observe — quote the
process.env/import.meta.envread and whether the name exists in each env - Interpret — which runtime path breaks if that name is missing or public-prefixed?
- Classify — referenced-but-unset / naming drift / secret reuse / hardcoded / dead
- Severity — prod-missing or public-prefix secret = P0 / Critical
Worked example
Observe:
process.env.STRIPE_WEBHOOK_SECRETused inapp/api/stripe/route.ts; name absent from Vercel prod; present locally. Interpret: deploy is green; webhook verify fails only in prod. Classify: referenced-but-unset (prod). Severity: P0. Finding:STRIPE_WEBHOOK_SECRET| prod absent | P0 | set the name; never print the value
Phase 0 — Enumerate environments and sources [HIGH freedom]
- Envs: local, preview/staging, prod
- Sources:
.env*,.env.example, Vercel/Supabase/Fly dashboards, CI secrets, runtime config - Demanded set: every
process.env.X/import.meta.env/ config object read
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-env-parity is a skill published in the GitHub repository kensaurus/cursor-kenji (9 stars, last pushed 11d ago), licensed MIT. It adds 69 tokens to every session and 1,310 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.
