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 | $0.05040 | $0.05040 |
| Opus 5 | $0.02520 | $0.02520 |
| Sonnet 5 | $0.01008 | $0.01008 |
| Haiku 4.5 | $0.00504 | $0.00504 |
Grade A, and why
enu 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 9d 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 — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Qué es este proyecto
enu es un motor para construir coding harnesses a medida («a
self-extensible coding harness with no host runtime», ADR-025): un único
binario Go con un kernel mínimo donde todo lo demás — incluido el agente
oficial, que es la demo de referencia del motor — son extensiones Lua.
Crítico: por defecto el proyecto está en fase de diseño. Los documentos
en docs/ son el proyecto. La API se valida escribiendo pseudocódigo contra
ella antes de congelarla. Tu trabajo en una tarea de diseño es diseño y
documentación (razonar sobre la API, encontrar grietas, registrar
decisiones): no crees ficheros de código Go o Lua salvo que se pida
explícitamente; el pseudocódigo ilustrativo vive dentro de los .md.
Excepción — fase de construcción: cuando la tarea sea implementar el kernel, se rige por docs/plan/implementacion.md y su protocolo de sesión (una feature por sesión, puntero, checkpoints, tests). Eso es "pedirlo explícitamente": ahí sí se escribe código. El default "no código" sigue valiendo para todo lo demás. Cómo operar en esa fase: la sección "Cuando implementes" de abajo.
Idioma y estilo
- La fuente documental interna está en español (
docs/— contratos, ADR, findings, plan, worklog — y los mensajes de commit). Escribe en español, con el mismo registro: prosa densa pero precisa, frases que justifican el porqué de cada decisión, no solo el qué. El frente público va en inglés (ADR-025): README, web de docs, quickstart y cualquier artefacto de adquisición se redactan en inglés primero, con versión española enlazada donde exista. - Los identificadores de la API son en inglés y
snake_case(enu.fs.read,enu.task.spawn); la prosa que los rodea, en español. - Tono: afirmativo y razonado. Cada decisión se acompaña de su motivación y, cuando aplica, de las alternativas descartadas. Imita la voz de los documentos existentes antes de añadir nada.
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.

enu CLAUDE.md is an instructions file published in the GitHub repository dbareagimeno/enu (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 5,040 tokens to every session, about $0.0252 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
