They reduce the chance of shipping untested changes, missing browser checks, or making unapproved changes to GitHub.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is damiansire/web-vaccine-tracker's own configuration. It tells Codex and OpenCode how to work on web-vaccine-tracker itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything web-vaccine-tracker configures →

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.

Security

Grade A, and why

web-vaccine-tracker 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 8d 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.

What it actually says

AGENTS.md

Guía para cualquier agente (o humano) que abra este repo. La barra de calidad completa vive en CLAUDE.md — no la dupliques acá, léela antes de tocar código. Esto es el checklist operativo.

Checklist pre-PR (numerado, en orden)

  1. npm run verify en verde (lint + test + build) — es literalmente el mismo comando que corre CI.
  2. Si tocaste dominio/lógica (no solo estilos/copy), agregá o actualizá un test que lo cubra.
  3. Si tomaste una decisión no obvia (elegiste A sobre B, descartaste un hallazgo, te desviaste del patrón existente), dejá una línea en _audits/DECISIONES.md con el porqué.
  4. Si agregaste una regla nueva de arquitectura/stack, reflejala en CLAUDE.md — no dejes la barra desactualizada respecto al código real.
  5. Verificá visualmente en el navegador cualquier cambio de UI antes de darlo por terminado (no alcanza con "compila y los tests pasan").

STOP-signs (parar y preguntar, no improvisar)

  • Nunca git push ni ninguna operación de escritura a GitHub sin pedido explícito — el dueño del repo lo hace a mano.
  • Nunca agregar una segunda librería de UI/estilos (el repo anterior tenía cuatro sistemas de estilo compitiendo — ver CLAUDE.md).
  • Nunca volver a echarts-for-react; el wrapper propio (src/components/EChart.tsx) existe porque ese paquete tiene un bug real de interop con Vite (ver _audits/DECISIONES.md).
  • Nunca hacer fetch en runtime al dataset de OWID — el dominio está cerrado, el dataset se hornea a build-time (npm run generate:data) y se versiona junto al código.
  • Si un cambio requiere instalar una dependencia nueva, pará y justificá por qué el problema no se resuelve con lo que ya está — el patrón de este repo es preferir código chico propio sobre una dependencia (ver el wrapper de EChart, o assertLastDataRows en vez de Zod).
Changes

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.
