changelog-mcp: Skill for Claude Code

.claude/skills/changelog/SKILL.md

changelog is a skill for Claude Code from smartsys/changelog-mcp. It costs 46 tokens per session (1,657 once invoked), scanned A, original, MIT.

A helper for recording changes in a project's changelog, a dated list of notable updates. It examines the current Git changes and follows the project's configured changelog format.

In plain words
What is it for?
For creating changelog entries after code changes, when the project has been initialized for changelog storage.
Why use it?
It turns completed implementation work into a consistent record instead of requiring you to write the entry from scratch.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter.

This is smartsys/changelog-mcp's own configuration. It tells Claude Code how to work on changelog-mcp 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 changelog-mcp 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

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 1mo 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/changelog

Erstellt einen Changelog-Eintrag für die aktuelle Arbeit.

Voraussetzung: einmal init_changelog

Vor dem ersten Changelog-Eintrag müssen Store und Config existieren. Sind sie noch nicht angelegt — oder meldet ein Tool „Konfiguration fehlt" bzw. „In CHANGELOG_MCP_CONFIG angegebene Konfiguration fehlt" — einmal init_changelog ausführen. Es legt Store und Config-Datei an (am Pfad aus CHANGELOG_MCP_CONFIG, sonst im Projekt-Root) und ist idempotent: ein zweiter Aufruf überschreibt nichts. Das gilt pro Projekt — es gibt keinen globalen Changelog.

Execution

User provided context: "$ARGUMENTS"

Schritt 1: Änderungen analysieren

Analysiere was in der aktuellen Session geändert wurde:

  1. git status - Ungetrackte und geänderte Dateien
  2. git diff HEAD - Aktuelle Änderungen
  3. git log --oneline -5 - Letzte Commits für Kontext

Falls keine Änderungen vorhanden sind, frage den User was dokumentiert werden soll.

Schritt 2: Changelog-Eintrag vorbereiten

Bestimme aus den Änderungen:

  • Kategorie: hängt vom aktiven Format ab (get_config zeigt es). Achtung: keep-a-changelog und conventional validieren strikt — eine unbekannte Kategorie lässt add_entry fehlschlagen:
    • smart (Default): frei wählbar. Empfehlung: Added, Changed, Deprecated, Removed, Fixed, Security, Documentation.
    • keep-a-changelog (strikt): nur Added, Changed, Deprecated, Removed, Fixed, Security.
    • conventional (strikt): nur Features, Bug Fixes, Performance, Reverts, Breaking Changes.
  • Beschreibung: Kurze Zusammenfassung der Änderung (1 Zeile)
  • Details: Technische Details als Liste
  • Dateien: Geänderte Dateien mit Beschreibung
  • Version-Bump: bump = patch (Default, Fehlerbehebung/Kleinigkeit), minor (neue, abwärtskompatible Funktion) oder major (Breaking Change). Wirkt nur im Modus semver; bei patch-only wird bump ignoriert (nur die Patch-Stelle zählt hoch).
  • Privat?: private=true setzen, wenn die Änderung nicht-öffentliche Doku/interne Arbeit betrifft, die nicht im publizierten Changelog erscheinen soll. Im Zweifel nachfragen.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
