enu: Skill for Claude Code

.claude/skills/salud/SKILL.md

salud is a skill for Claude Code from dbareagimeno/enu. It costs 100 tokens per session (1,249 once invoked), scanned A, original, Apache-2.0.

A repository health check described in Spanish that mechanically looks for certain failures using fuzzing, race testing, vulnerability scanning, and mutation testing.

In plain words
What is it for?
Use it for periodic or change-triggered checks of a Go repository, especially its fuzz tests, race behavior, dependency vulnerabilities, and test strength.
Why use it?
It checks failure modes that ordinary continuous integration and code review may miss, including unusual inputs, concurrency problems, and known vulnerabilities.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths.

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 →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go test ./internal/runtime/ -run "^$t$" -fuzz "^$t$" -fuzztime 3m.

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

salud 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 10d 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.

Pasada de salud (capa mecánica)

Cuatro detectores mecánicos: reproducibles, sin falsos positivos de LLM, y cada uno caza una familia de fallos que las verificaciones habituales (CI por push, DoD por sesión, juicio por diff) no cubren. El principio: el calendario solo es buen trigger para lo que cambia aunque el código no cambie (el corpus de fuzzing crece, las CVEs se publican, los interleavings son loterías); para lo demás el trigger es el cambio (eso ya lo hacen CI y /juicio).

Ejecuta los cuatro pasos; los largos, en paralelo/segundo plano. Presupuesto orientativo total: 30-45 min de máquina, casi todo desatendido.

1 · Fuzzing (dianas en internal/runtime/fuzz_test.go)

Seis dianas con invariantes fuertes sobre la lógica 🔒: FuzzSSEChunkSplit (S20, equivalencia bajo partición de chunks), FuzzDecodeInputChunkSplit (CP-7, disciplina pending/flush del driver), FuzzComputeDiffReconstruct (S25, aplicar los hunks reconstruye b), FuzzWrapText y FuzzTruncateText (S22, anchura acotada + contenido conservado), FuzzMarkdownStreamingSafe (S23, prefijos arbitrarios no rompen).

for t in FuzzSSEChunkSplit FuzzDecodeInputChunkSplit FuzzComputeDiffReconstruct \
         FuzzWrapText FuzzTruncateText FuzzMarkdownStreamingSafe; do
  go test ./internal/runtime/ -run "^$t$" -fuzz "^$t$" -fuzztime 3m
done
  • El corpus vive en $GOCACHE/fuzz y se acumula entre pasadas: cada ejecución parte de donde llegó la anterior — el tiempo invertido se compone.
  • Un fallo deja un caso mínimo en internal/runtime/testdata/fuzz/<diana>/: commitéalo (se convierte en test de regresión permanente que CI ejecuta como semilla) y trata el fallo como hallazgo: ¿bug de código (→ arreglar citando la diana) o invariante mal formulado en la diana (→ corregir la diana explicando por qué)?
  • Si una sesión nueva añade lógica 🔒 parseadora o con bordes, añade su diana aquí; el inventario de dianas crece como el 🔒: nunca se relaja.
  • CI solo ejecuta las semillas (un go test normal no fuzzea): el coste del fuzzing vive en esta skill, no en cada push.

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.

salud is a skill published in the GitHub repository dbareagimeno/enu (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 100 tokens to every session and 1,249 once invoked, about $0.0005 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.
