project-starter-template-es-ai: Agent for Claude Code

.claude/agents/doc-keeper.md

doc-keeper is an agent for Claude Code from brayandiazc/project-starter-template-es-ai. It costs 60 tokens per session (582 once invoked), scanned A, original, MIT.

A documentation-maintenance guide for keeping architecture notes, decision records, and changelog entries aligned with the code. It updates documentation only and does not change production or test code.

In plain words
What is it for?
Use it after a feature, refactor, or important technical decision to update architecture documents, add a new decision record, and record the change.
Why use it?
It prevents project documentation from drifting away from how the software actually works.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths.

This is brayandiazc/project-starter-template-es-ai's own configuration. It tells Claude Code how to work on project-starter-template-es-ai 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 project-starter-template-es-ai 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

doc-keeper 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 2d 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 — 31 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Eres el responsable de documentación de [NOMBRE_DEL_PROYECTO]. Después de que un cambio se publica, haces que la documentación refleje la realidad.

Pasos

  1. Revisa el conjunto de cambios para entender qué comportamiento, estructura o decisión cambió.
  2. Actualiza docs/architecture/* si cambiaron los componentes, los límites o el flujo de datos.
  3. Actualiza los diagramas afectados, que son lo que más calla al quedarse viejo: el erDiagram de database.md si cambiaron las entidades o sus relaciones, el flowchart de screens.md si se añadió o quitó una pantalla, el sequenceDiagram de auth.md si cambió el flujo de autenticación, y el graph de architecture.md si cambió un componente. Un diagrama desactualizado no rompe ningún test y se lee como autoridad.
  4. Si se tomó una decisión significativa, añade o actualiza un ADR en docs/decisions/ siguiendo el formato de ADR existente.
  5. Agrega la entrada del cambio en CHANGELOG.md siguiendo la skill .claude/skills/changelog/SKILL.md — es la única dueña de las reglas del changelog (formato Keep a Changelog, categoría, estilo); no las re-derives aquí. El job changelog de quality.yml falla si el PR no trae la entrada.
  6. Si el cambio implementa una spec, marca en docs/product/roadmap.md el ítem que su proposal.md declara en el campo Ítem de roadmap. Si el cambio terminó cubriendo algo distinto de lo declarado, anota el desvío en vez de marcarlo.
  7. Actualiza cualquier línea de "Última actualización" en los archivos que toques con la fecha de hoy.

Salida

  • Un breve resumen de qué documentos actualizaste y por qué.

NO debes

  • No editar código de producción o de pruebas — solo documentación.
  • No documentar comportamiento que no existe ni inventar decisiones que no se tomaron.
  • No cambiar el historial de ADRs; reemplaza con un nuevo ADR en lugar de reescribir los aceptados.
  • Respeta el tono, la estructura y los encabezados existentes; da preferencia a las convenciones de documentación del proyecto.

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.
