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 | $0.02288 | $0.02288 |
| Opus 5.5 | $0.00915 | $0.00915 |
| Sonnet 5.5 | $0.00458 | $0.00458 |
| Haiku 4.5 | $0.00229 | $0.00229 |
Grade A, and why
curb AGENTS.md 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 1mo 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CURB — SF street parking, block by block
Context for Codex. Read this before editing.
What it is
A mobile-first web app that shows San Francisco street-parking rules on an interactive map: where you can park, until when it's swept, whether it's metered, and whether it's a residential permit (RPP) zone. Lets the user set a calendar reminder before the next sweep.
Stack (intentionally minimal)
- Single static file:
index.html. No build step, no framework, no bundler. - Vanilla JS + Leaflet 1.9.4 (from cdnjs) for the map.
- Basemap: official Google Map Tiles API when
GMAPS_KEY(orwindow.GMAPS_KEY) is set — session-token flow ininitBasemap(), viewport attribution refreshed on moveend. Falls back to keyless CARTO Voyager raster tiles when no key / on any failure. Leaflet stays the map engine either way. The Google key is a client key (referrer-restrict it) kept OUT of the public repo: local dev reads a gitignoredconfig.js(fromconfig.example.js); on Vercel,api/config.jsemitswindow.GMAPS_KEYfrom theGMAPS_KEYenv var andvercel.jsonrewrites/config.js→/api/config. - Everything is client-side. Data is fetched live from DataSF (Socrata) at runtime.
- Design system: fonts Anton (display) + Hanken Grotesk (body); "transit signage" aesthetic; color tokens in :root (--green clear / --amber soon / --red now / --meter permit-blue / paper+ink). Keep this language if extending the UI.
Data sources (all DataSF Socrata, CORS-open: access-control-allow-origin: *)

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.
