spec-kit-template: Skill for Claude Code

.github/skills/spec-kit-rfc-proposal/SKILL.md

spec-kit-rfc-proposal is a skill for Claude Code, Codex from lksnext-ai-lab/spec-kit-template. It costs 0 tokens per session (1,674 once invoked), scanned A, original, Apache-2.0.

A Spanish-language RFC, or design proposal, that summarises and connects specifications stored in a project’s docs/spec folder.

In plain words
What is it for?
Use it to create or update architecture or executive RFCs and record which specification files informed them.
Why use it?
It gives stakeholders one narrative view of planned work, decisions, trade-offs, risks, and unresolved questions without replacing the detailed specification.

Written for no agent in particular: nothing here depends on one.

This is lksnext-ai-lab/spec-kit-template's own configuration. It tells Claude Code and Codex how to work on spec-kit-template 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 spec-kit-template 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

spec-kit-rfc-proposal 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 12d 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.

SKILL: rfc-proposal

Propósito

Crear/actualizar un RFC narrativo en español que resuma y conecte la especificación distribuida en docs/spec/**, sin sustituirla.

El RFC sirve para:

  • Alinear stakeholders (qué se va a hacer y por qué).
  • Consolidar decisiones (ADRs) y trade-offs.
  • Identificar riesgos y gaps (OPENQ) sin “rellenar”.

Inputs (mínimo)

  • ROOT_SPEC_DIR: docs/spec/
  • RFC_ID (opcional): RFC-0001, RFC-0002, ...
  • SLUG (opcional): texto corto del cambio (kebab-case)
  • VARIANTE (opcional): architecture (default) | executive
  • FOCUS (opcional): 3–8 bullets con énfasis (p.ej. “seguridad”, “operación”, “migración”, “frontend”).

Outputs (obligatorio)

  • RFC Markdown en docs/spec/rfc/:

    • architecture: docs/spec/rfc/<RFC_ID>-<slug>.md
    • executive: docs/spec/rfc/<RFC_ID>-<slug>-executive.md
  • Sección final “Fuentes utilizadas” con listado de ficheros docs/spec/** consultados y motivo (1 línea c/u).

Opcional (solo si el repositorio ya lo está usando): crear/actualizar docs/spec/_inputs/rfc/<RFC_ID>/sources.md con el mismo listado de fuentes.


Hard rules (no negociables)

  1. Idioma: todo en español.

  2. No inventar

  • No afirmar hechos/decisiones/cifras/contratos/SLAs/endpoints si no están en docs/spec/**.
  • Si falta evidencia: escribir OPENQ: y enlazar a ../95-open-questions.md (o indicar dónde debe crearse).
  1. Separación as-is / to-be
  • “Confirmado (as-is)” solo si hay evidencia explícita en spec.
  • “Propuesta / decisión” debe quedar claramente como tal.
  • Si es hipótesis: marcar HIPÓTESIS: o convertir en OPENQ si es crítica.
  1. Evidencias por sección
  • Cada sección del RFC termina con:
    • **Evidencias:** + links relativos (mín. 1).
  • Secciones críticas (seguridad/operación/migración/alternativas) requieren ≥2 evidencias si existen fuentes.
  1. Contradicciones
  • Si dos fuentes se contradicen:
    • DISCREPANCIA: + descripción + links a ambas.
    • Si bloquea decisión: OPENQ.

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.
