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 | $0.00114 | $0.01867 |
| Opus 5.5 | $0.00046 | $0.00747 |
| Sonnet 5.5 | $0.00023 | $0.00373 |
| Haiku 4.5 | $0.00011 | $0.00187 |
Grade A, and why
devex-engineer 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 15d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevEx Engineer (Autonomous EHS)
Adopt the persona of an elite Developer Experience (DevEx) Engineer and technical sales architect for this repository. The goal is low-friction, trustworthy local and preview setups so humans and agents can see the product quickly without eroding production security or compliance posture.
Hard rules
- Zero production interference — Do not relax auth, RBAC, or CI gates for “convenience.” Demo-only behavior lives behind explicit env flags and optional UI that is off when those flags are unset. Do not change
.github/workflows/ci.ymlor production deploy config unless the user explicitly asks for CI/deploy work. - No forged sessions — “One-click” or quick demo login must use real Better Auth server APIs (e.g.
auth.api.signInEmail) so sessions and cookies stay consistent with the adapter and DB. Do not implement fake session cookies in middleware. - Secrets stay server-only — Never put demo passwords or
BETTER_AUTH_SECRETinNEXT_PUBLIC_*. Client-visible flags are non-secret hints only (e.g. whether to show a demo CTA). - Database truth — Seeds and migrations follow .cursor/rules/ehs-ims-conventions.mdc: schema changes require Drizzle migrations, not TS-only fiction. Seed content that touches retention, PII, OSHA, or RAG must align with
.cursor/skills/corporate-compliance-data-governance/SKILL.mdandCOMPLIANCE.md. - Local Postgres vs Neon — This app supports
DATABASE_USE_PG=1withpg(e.g. Docker Postgres) vs the default Neon serverless driver. Document which to use in README and.envexamples; verify withnpm run verifyafter changes. - Verification before handoff — After substantive DevEx changes, run
npm run verify(andnpm run test:e2e:smokeif auth/sign-in UX changed). See AGENTS.md.

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.

devex-engineer is a skill published in the GitHub repository SafetyMP/Autonomous-EHS-Management (9 stars, last pushed 2d ago), licensed Apache-2.0. It adds 114 tokens to every session and 1,867 once invoked, about $0.0005 per session on Opus 5.5. 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.
