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 | $0.01270 | $0.01270 |
| Opus 5 | $0.00635 | $0.00635 |
| Sonnet 5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
mercadona-user-story-toolkit 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 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Instrucciones para trabajar con este repositorio. Este toolkit es un plugin de Claude Code (skills + slash commands en Markdown + scripts Python auxiliares). No es código de aplicación; es contenido prompt-engineered con el que se cargan agentes.

Versionado y releases
El versionado sigue SemVer sobre el campo version de .claude-plugin/plugin.json. Los tags vX.Y.Z y las GitHub Releases los crea automáticamente la CI (.github/workflows/release.yml) cuando detecta un cambio en plugin.json al mergear a main.
Regla obligatoria: cualquier cambio que se mergee a main debe ir acompañado de un bump de version en .claude-plugin/plugin.json. Si no se bumpea, no hay release.
Cómo decidir el bump
Aplicar SemVer al contrato del plugin (lo que un usuario invoca o consume), no al código interno:
-
PATCH (
x.y.Z) — corrección sin cambio de comportamiento observable:- Typos, mejoras de redacción en SKILL.md o commands/
- Bug fixes en scripts/ o bridge/ que dejan los mismos inputs/outputs
- Refactor interno de un script
- Documentación (
README.md,CONTRIBUTING.md,examples/)
-
MINOR (
x.Y.0) — funcionalidad aditiva, retrocompatible:- Nueva skill o nuevo command
- Nuevo flag opcional en un command existente
- Nueva heurística aditiva en una skill (no cambia las existentes)
- Nuevo bridge / nuevo formato de PRD soportado
- Nuevo script en
scripts/invocado por skills
-
MAJOR (
X.0.0) — cambio incompatible para usuarios existentes:- Renombrar o eliminar una skill o un command
- Cambiar inputs/outputs requeridos de una skill (rompe pipelines existentes)
- Cambios estructurales en
plugin.jsonoshared-config.mdque requieran migración - Eliminar un flag, hacer obligatorio un flag antes opcional
- Cambio de comportamiento por defecto que altere outputs en escenarios existentes
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.
