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

changelog-auto 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 7d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/dc:changelog-auto

Objetivo

Parsear el historial de commits convencionales (feat, fix, docs, refactor, etc.) y generar automáticamente una sección de CHANGELOG.md en formato Keep a Changelog, agrupando cambios por versión, fecha y categoría. Elimina la carga manual de mantener el changelog.

Uso

/dc:changelog-auto
/dc:changelog-auto --from v1.2.0 --to HEAD
/dc:changelog-auto --version 1.3.0
/dc:changelog-auto --dry-run
/dc:changelog-auto --format keepachangelog

Comportamiento

  1. Detectar rango: desde el último tag de versión hasta HEAD (o el rango especificado con --from/--to)
  2. Parsear commits convencionales:
    • feat: → Added
    • fix: → Fixed
    • refactor: → Changed
    • docs: → Changed (documentación)
    • perf: → Changed (performance)
    • test: → omitido por default (configurable)
    • chore: → omitido por default (configurable)
    • BREAKING CHANGE → sección separada al tope
  3. Detectar versión: desde el último tag semver o usar --version si se provee
  4. Agrupar por categoría: Added, Changed, Fixed, Removed, Security, Deprecated
  5. Insertar la nueva sección al tope del CHANGELOG.md existente (no sobrescribir)
  6. Con --dry-run: solo imprimir sin modificar el archivo

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.
