.claude/skills/changelog/SKILL.md

changelog is a skill for Claude Code from brayandiazc/project-starter-template-es-ai. It costs 82 tokens per session (470 once invoked), scanned A, original, MIT.

A workflow for updating CHANGELOG.md, the file that records notable product changes, using the Keep a Changelog format. It summarizes current changes under the Unreleased section.

In plain words
What is it for?
Use it after code changes to add suitable entries for new features, behavior changes, removals, fixes, or security work.
Why use it?
It keeps release notes up to date and makes changes easier for users to understand than a raw list of commit messages.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is brayandiazc/project-starter-template-es-ai's own configuration. It tells Claude Code how to work on project-starter-template-es-ai 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 project-starter-template-es-ai 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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00082 $0.00470
Opus 5 $0.00041 $0.00235
Sonnet 5 $0.00016 $0.00094
Haiku 4.5 $0.00008 $0.00047

Security

Grade A, and why

changelog 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 4d 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.

What it actually says

Añade los cambios actuales a CHANGELOG.md.

  1. Lee CHANGELOG.md para coincidir con su estilo existente y confirma que sigue Keep a Changelog (https://keepachangelog.com). Asegúrate de que exista una sección ## [Unreleased] al inicio; créala si falta.
  2. Determina qué cambió desde la última versión: revisa los commits recientes (git log <last-tag>..HEAD --oneline) y/o el diff del working tree.
  3. Resume los cambios en las categorías estándar bajo Unreleased, creando solo las subsecciones que apliquen:
    • Added — nuevas funcionalidades.
    • Changed — cambios en el comportamiento existente.
    • Deprecated — funcionalidades que pronto se eliminarán.
    • Removed — funcionalidades eliminadas.
    • Fixed — correcciones de errores.
    • Security — correcciones de vulnerabilidades.
  4. Escribe las entradas como viñetas concisas y orientadas a la persona usuaria (qué cambió y por qué importa), no mensajes de commit en crudo. Vincula issues/PRs si el archivo lo hace.
  5. Si el cambio implementa una spec, marca también el ítem que su proposal.md declara en el campo Ítem de roadmap dentro de docs/product/roadmap.md — CHANGELOG y roadmap viajan en el mismo PR (docs/conventions/workflow.md, reglas 5 y 6).
  6. Informa las líneas que añadiste.

Ejemplo: bajo ### Fixed- Prevent crash when saving an empty form (#142).

NO publiques una versión con número (no muevas Unreleased a una versión con fecha) a menos que la persona lo pida explícitamente. NO incrementes números de versión por tu cuenta.

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.
