enu: Skill for Claude Code

.claude/skills/hallazgo/SKILL.md

hallazgo is a skill for Claude Code from dbareagimeno/enu. It costs 93 tokens per session (1,194 once invoked), scanned A, original, Apache-2.0.

A Spanish-language workflow for handling a documented project finding, meaning a discovered gap or problem in the project’s rules or design.

In plain words
What is it for?
It creates a finding record, checks whether the existing API already covers it, compares resolution options, updates documents, and audits related decisions.
Why use it?
It helps ensure a finding is recorded, evaluated, resolved consistently, and reflected across all affected documents.

This is dbareagimeno/enu's own configuration. It tells Claude Code how to work on enu 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 enu 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

hallazgo 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.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ciclo de un hallazgo G##

Una grieta que la v1 necesita cerrada se resuelve una a una y no está hecha hasta ser coherente en todos los documentos. El código es el último eslabón de la cadena, no el primero: si el hallazgo nació implementando, la implementación espera a que los documentos cierren.

Pasos

  1. Registrar. Crea docs/findings/gNN-<slug>.md con el siguiente número G## libre (el índice de docs/findings/README.md lo dice; ojo a los huecos reservados que anota). El fichero lleva frontmatter de tipo hallazgo (type: hallazgo, id: GNN, status: abierto, origin: <de dónde salió>) y el formato de siempre: H1 # GNN · <título corto> — <docs afectados>, y los bloques Problema (la grieta, con la frase textual de la espec que se queda corta), Impacto (a quién afecta y con qué urgencia) y Opciones ((a), (b), (c)... cada una con su porqué). Añade su fila a la tabla índice de docs/findings/README.md y actualiza el contador de la cabecera (N registradas, N resueltas, N abiertas).

  2. ¿Ya es expresable? Antes de inventar API, lanza el agente verificador con el hallazgo: su mandato es demostrar que el escenario ya se compone con la API existente (el precedente: el semáforo con nu.task.future). Si vuelve FALSO POSITIVO con la composición como evidencia, el G## se cierra como demostrado-expresable: se documenta la composición en la resolución y no se toca la API. Este paso mata la mayoría de hallazgos baratos.

  3. Decidir. Presenta las opciones al usuario con tu recomendación motivada (qué rompe menos, qué compone mejor, qué precedente sienta). Si la resolución añade o toca api.md, lanza antes juez-filosofia con la propuesta: una OBJECIÓN bloqueante vuelve al usuario. Toda adición a la API exige bump de nu.version.api y crece solo por adición.

  4. Aplicar a TODOS los documentos. Busca con Grep cada contrato y pseudocódigo que presuponía la semántica vieja (agente.md, providers.md, sesiones.md, chat.md, guia-plugins.md, pseudocodigo.md, arquitectura.md, modelo-ejecucion.md... el corpus completo) y actualízalos. Deja el rastro: cada cambio cita el G## que lo motiva.

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.
