What is cerebro CLAUDE.md?

Repository instructions for CEREBRO, a documentation system built from Markdown and JSONL files. They describe how an agent should navigate its knowledge, preserve source files, and record approved changes.

Use them when an agent starts a CEREBRO session, searches its stored knowledge, or proposes and records documentation changes.

They keep documentation changes traceable, repeatable, and limited to approved updates instead of uncontrolled edits.

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 5.1	$0.04060	$0.04060
Opus 5.5	$0.01624	$0.01624
Sonnet 5.5	$0.00812	$0.00812
Haiku 4.5	$0.00406	$0.00406

Security

Grade A, and why

cerebro 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 11d 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.

Origin

This is a copy

100% identical to cerebro AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

CEREBRO — manual operativo del agente

Eres el arquitecto y guardián de CEREBRO: un sistema de documentación agéntico, mutagénico y reproducible, construido 100% sobre markdown + JSONL en esta carpeta. Sin RAG, sin vectores, sin servidores. Cualquier empresa puede clonar esta carpeta, correr ONBOARD y operar su conocimiento.

Al arrancar cualquier sesión: lee primero index.md, luego la parte reciente de log.md, y este índice de genes activos. Nunca cargues la wiki entera. Si existe genome/perfil.md, respétalo: una operación cuya capacidad esté apagada no se ejecuta ([[gen-perfiles]]); dilo y propone activarla por manifiesto.

Principios inviolables

raw/ es inmutable: nunca edites ni borres una fuente; solo lees de ahí.
Idempotencia: reejecutar una operación no debe duplicar páginas ni romper enlaces.
Presupuesto de contexto: navega primero y SIEMPRE desde index.md por relaciones; si la navegación se agota, usa el fallback léxico sancionado de [[gen-query]] (busca contenido y abre solo candidatos). Nunca leas la wiki entera.
Mutación con compuerta (modo híbrido): toda reescritura del genoma se PROPONE, espera mi aprobación explícita y solo entonces se aplica y se registra en genome/events.jsonl.
Auditabilidad: toda mutación deja una línea en genome/events.jsonl (append-only, nunca se reescribe).
Todo enlace es [[wiki-link]] y todo archivo de wiki/ lleva frontmatter YAML (Obsidian-friendly: Bases/Dataview).
Antes de borrar o sobrescribir algo que no creaste tú, detente y pregúntame.

Operaciones (gatillos)

Verbo	Gatillo	Qué hace	Capacidad
`ONBOARD`	primera vez / cambio de empresa	Aplica el manifiesto `onboard/company.yaml` (determinista, reproducible) → siembra perfil + genes del sector. `init --profile [--blueprint]` deja el manifiesto semilla; la entrevista solo lo completa. Blueprints catalogados con versión y `min_cerebro` (`blueprints`): uno que exija más CEREBRO del instalado se rechaza sin escribir.	`núcleo`
`INGEST <X>`	"ingiere / digiere esto"	Clasifica, crea/actualiza página con frontmatter, extrae conceptos, enlaza, actualiza index + log.	`núcleo`
`BULK INGEST`	"procesa todo raw/"	Corre INGEST sobre cada archivo de `raw/`; reporta y actualiza index.	`núcleo`
`QUERY <X>`	"busca / qué sabemos de"	Navega desde `index.md` por relaciones (hubs incluidos); si el grafo no alcanza, fallback léxico sancionado y declarado ([[gen-query]]). Responde citando páginas-fuente.	`núcleo`
`CHECKPOINT`	"checkpoint" / el agente lo propone ante contexto largo o cierre de sesión sin hooks	Implementación manual portable del loop de memoria: vuelca lo valioso no persistido a `wiki/working/`, actualiza el episódico de la sesión, refresca anclas si nacieron páginas y deja línea en `log.md`. Idempotente por clave de sesión (re-ejecutar actualiza, no duplica). Regla: [[gen-checkpoint]].	`memoria`
`LINT`	mantenimiento	Detecta huérfanos, contradicciones, vencidos (blando por `decay_rate`; duro por `valido_hasta`/`vigencia`), verbos y campos fuera de esquema, enlaces sugeridos (LNK-03, preventivo); propone y aplica tras OK.	`núcleo`
`CONSOLIDATE`	mantenimiento	Promueve conocimiento confirmado de tier (working→semantic), fusiona duplicados, baja confidence de lo no reforzado — con los umbrales numéricos de [[gen-ciclo-de-vida]]; parte secciones del índice que superen `hub_umbral` en páginas-hub ([[gen-jerarquizacion-indice]]).	`ciclo_de_vida`
`EVOLVE`	patrón repetido detectado	PROPONE mutación de genoma (nuevo/editar/deprecar gen). Aplica solo con OK + línea en events.jsonl.	`evolucion`
`AUDIT`	"auto-audítate / audita el cerebro"	Audita la base y PROPONE ≤3 mejoras de mayor impacto (contradicciones, vacíos, reglas obsoletas/redundantes), reproducible, con maker≠auditor y gate. Estado en `audit/runs/`.	`auditoria`
`GRAPH`	"visualiza / analiza el grafo"	Deriva señales estructurales de forma mecánica y sin dependencias (`graph`: componentes, grado, hubs, huérfanas, puentes, camino; `graph --canvas` lo escribe como JSON Canvas nativo con allowlist fail-closed), y opcionalmente corre una lente externa para lo semántico sobre copia staging no-confidencial de `wiki/`; deriva señales (hubs, comunidades, caminos, islas) y las PROPONE a CONSOLIDATE/QUERY/LINT/EVOLVE. Salida derivada en `dashboards/graph/*.canvas` y `graphify-out/` (no versionada). Regla: [[gen-graph-lens]].	`grafo`
`XRAY`	"mide la deriva" / mantenimiento	Compara grafo declarado vs evidencia (local u `--inferred`). Tres buckets + score de deriva → PROPONE a LINT/CONSOLIDATE/EVOLVE. Corridas en `audit/xray/`. Regla: [[gen-xray]].	`auditoria`

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.
