What is curb AGENTS.md?

Repository instructions for Curb, a mobile web app showing San Francisco street-parking rules on an interactive map. It covers parking meters, street sweeping, residential permits, and calendar reminders.

They are for guiding edits to the single HTML file, map display, live DataSF data, map tiles, parking-rule searches, and sweep reminders.

They keep the app's simple setup and important map, data, and security decisions from being changed accidentally by a coding agent.

Token cost

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	$0.02305	$0.02305
Opus 5	$0.01153	$0.01153
Sonnet 5	$0.00461	$0.00461
Haiku 4.5	$0.00231	$0.00231

Security

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 4d 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.

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 (or window.GMAPS_KEY) is set — session-token flow in initBasemap(), 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 gitignored config.js (from config.example.js); on Vercel, api/config.js emits window.GMAPS_KEY from the GMAPS_KEY env var and vercel.json rewrites /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: *`)

Street sweeping — yhqp-riqs https://data.sfgov.org/resource/yhqp-riqs.json Fields: cnn (segment id), corridor, limits (cross streets), blockside, cnnrightleft (L/R vs digitized direction), weekday, fromhour, tohour, week1..week5 ("1"/"0" = Nth occurrence of that weekday in the month), line (GeoJSON LineString). CURRENT data.
Parking meters — 8vzz-qzz9 https://data.sfgov.org/resource/8vzz-qzz9.json Fields: street_name (UPPERCASE), cap_color, on_offstreet_type, lat/long, etc. CURRENT data. Used only for a street-level count (no spatial join — see limits).
Parking regulations / RPP — hi6h-neyh https://data.sfgov.org/resource/hi6h-neyh.json Fields: regulation, rpparea1 (permit-area letter), hrlimit, days, from_time, to_time, exceptions, shape (GeoJSON MultiLineString). STALE: this is SFMTA's 2017 set, flagged by the city as not comprehensively updated. Treat as a hint.

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.
