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 | $0.00064 | $0.01820 |
| Opus 5 | $0.00032 | $0.00910 |
| Sonnet 5 | $0.00013 | $0.00364 |
| Haiku 4.5 | $0.00006 | $0.00182 |
Grade A, and why
spec-kit-security-baseline 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: Security Baseline (spec-kit)
Objetivo
Dejar docs/spec/80-seguridad.md en un estado operable y verificable para MVP:
- AuthN (autenticación, sesiones/tokens)
- AuthZ (modelo, reglas por recurso)
- Protección de datos y secretos
- Auditoría / trazabilidad de acciones sensibles
- Controles de API e integraciones
- Threat-lite (amenazas → mitigaciones → verificación/evidencia)
Archivos que se pueden modificar
- Primario:
docs/spec/80-seguridad.md - Si aplica:
docs/spec/11-requisitos-tecnicos-nfr.md(NFRs de seguridad verificables/medibles)docs/spec/90-infra.md(secretos, hardening, retenciones operativas)docs/spec/40-arquitectura.md(impactos y patrones)docs/spec/adr/ADR-*.md(trade-offs)docs/spec/95-open-questions.md(gaps críticos)docs/spec/96-todos.md(pendientes no bloqueantes)
No tocar otros ficheros salvo petición explícita.
Reglas duras (anti-deriva)
- No inventar
- No asumir MFA/SSO, RBAC/ABAC, cifrado en reposo, retenciones, herramientas, ni niveles de logging si no están definidos.
- Si falta info que condiciona el diseño/aceptación:
OPENQ:(no rellenar).
- No secretos / no datos sensibles
- Nunca incluir valores reales (keys, tokens, passwords, certificados) ni datos personales en ejemplos.
- Regla de logs/errores: no deben exponer secretos ni datos sensibles (si aplica, declararlo como control + verificación).
- Vendor-neutral por defecto
- Describir patrones (OIDC, secrets manager, rate limiting) sin imponer proveedor/stack salvo evidencia explícita.
- Deny-by-default
- Por defecto, sin permiso explícito → acceso denegado.
- Excepciones solo si están justificadas y evidenciadas.
- Trade-offs relevantes → ADR
- Ej.: RBAC vs ABAC, scopes vs permisos granulares, auditoría detallada vs coste/privacidad, cifrado en reposo MVP vs fase 2, estrategia rotación.
- Clasificación: requerido vs recomendado En el documento, marcar explícitamente cada control como:
REQUERIDO(evidenciado o exigido por FR/NFR/ADR)RECOMENDADO(baseline sugerido)TBD/OPENQ(falta decisión o datos)
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.

spec-kit-security-baseline is a skill published in the GitHub repository lksnext-ai-lab/spec-kit-template (5 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 64 tokens to every session and 1,820 once invoked, about $0.0003 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.
