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 | $0.01986 | $0.01986 |
| Opus 5.5 | $0.00794 | $0.00794 |
| Sonnet 5.5 | $0.00397 | $0.00397 |
| Haiku 4.5 | $0.00199 | $0.00199 |
Grade A, and why
web-vaccine-tracker CLAUDE.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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — web-vaccine-tracker
Panel histórico de vacunación COVID-19. El dominio está cerrado (la pandemia
terminó): no hay API en vivo, el dataset es el histórico completo de
Our World in Data horneado a
build-time en src/data/ (formato columnar {fields, rows}, ver ese directorio
cuando exista). Arquetipo: app de dataviz, no librería — no aplican reglas de
exports map / tree-shaking / publicación npm.
Barra de calidad
Stack: Vite + React + TypeScript. Todo código nuevo se escribe CONTRA esta barra, no se audita después. Las prácticas de stack se apoyan en proyectos open source públicos, citados con su URL donde aplican.
Piso de craft (regla de intención clara)
- a. Nombres de dominio, no de mecanismo —
daily_vaccinations, nodata/item. - b. Comentarios explican el PORQUÉ, nunca el QUÉ.
- c. La firma pública se entiende sin leer el cuerpo.
- d/e. Un cambio de regla se edita en UN lugar. Ya nos mordió una vez (ver
git log—SelectCountryduplicado en dos carpetas del repo viejo, un fix aplicado a una copia y no a la otra). Si aparece una segunda variante de un componente, extraer unshared/parametrizable antes de que diverjan. - f/g. Estado inmutable, consistente ante excepción. El dataset es estático e
inmutable en runtime — cualquier
useState/derivado debe tratarlo como read-only; nada de mutar los JSON importados. - h. Fallos de carga de datos se loguean, nunca se tragan. Un país sin archivo
(
import()que rechaza) es un boundary — no un.catch(() => [])silencioso sin traza. El bug de pantalla-en-blanco del repo anterior (home rota porPromise.allsin.catch) fue exactamente esto. - i. Toda carga async tiene manejo de fallo explícito — usar
Promise.allSettledcuando un país faltante no debe tumbar el batch completo. - j. N/A (no hay auth/permisos en este repo — dataset público estático).
Piso de legibilidad en frío (k–m)
- k. El README lidera con una captura/GIF real del panel, no solo texto — es un artefacto visual, la descripción sola no cuenta como prueba.
- l. N/A por ahora — no hay claim de perf/robustez que probar hasta que exista el pipeline de datos real; cuando se agregue el fetch/build de OWID, documentar con qué se validó (conteo de filas, rango de fechas, países cubiertos).
- m. Framing honesto: el README debe decir explícitamente que los datos son históricos y fijos (no un tracker en vivo) — no reusar lenguaje de "en tiempo real" heredado de la versión COVID-era.
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.
