changelog-generator

changelog-generator is a skill for Claude Code, Codex from Morningstar202604/awesome-skillkit. It costs 107 tokens per session (1,797 once invoked), scanned A, a copy of changelog-generator, Apache-2.0.

A tool for turning Conventional Commits—commit messages with agreed prefixes such as feat and fix—into release notes and suggested semantic version changes. A monorepo is one repository containing multiple packages, and the workflow can filter changelogs by package.

In plain words
What is it for?
Generating CHANGELOG.md entries from Git ranges, choosing major, minor, or patch version bumps, checking commit-message format, and producing CI-friendly JSON.
Why use it?
It replaces manual sorting of Git history with consistent, reviewable release information while still allowing editorial control.

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-generator 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/commit_linter.py, scripts/generate_changelog.py, scripts/version_bumper.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changelog Generator

Tier: POWERFUL
Category: Engineering
Domain: Release Management / Documentation

Overview

Use this skill to produce consistent, auditable release notes from Conventional Commits. It separates commit parsing, semantic bump logic, and changelog rendering so teams can automate releases without losing editorial control.

Core Capabilities

  • Parse commit messages using Conventional Commit rules
  • Detect semantic bump (major, minor, patch) from commit stream
  • Render Keep a Changelog sections (Added, Changed, Fixed, etc.)
  • Generate release entries from git ranges or provided commit input
  • Enforce commit format with a dedicated linter script
  • Support CI integration via machine-readable JSON output

When to Use

  • Before publishing a release tag
  • During CI to generate release notes automatically
  • During PR checks to block invalid commit message formats
  • In monorepos where package changelogs require scoped filtering
  • When converting raw git history into user-facing notes

Key Workflows

1. Generate Changelog Entry From Git

python3 scripts/generate_changelog.py \
  --from-tag v1.3.0 \
  --to-tag v1.4.0 \
  --next-version v1.4.0 \
  --format markdown

2. Generate Entry From stdin/File Input

git log v1.3.0..v1.4.0 --pretty=format:'%s' | \
  python3 scripts/generate_changelog.py --next-version v1.4.0 --format markdown

python3 scripts/generate_changelog.py --input commits.txt --next-version v1.4.0 --format json

3. Update CHANGELOG.md

python3 scripts/generate_changelog.py \
  --from-tag v1.3.0 \
  --to-tag HEAD \
  --next-version v1.4.0 \
  --write CHANGELOG.md

4. Compute the Next Version From Commits

When the user has not decided the next version, derive it instead of guessing:

git log v1.3.0..HEAD --oneline | \
  python3 scripts/version_bumper.py --current-version 1.3.0 --output-format json

Output JSON contains recommended_version, bump_type (major/minor/patch/none), and with --include-commands the exact git tag commands. Feed recommended_version into generate_changelog.py --next-version. Pre-releases: add --prerelease alpha|beta|rc. Input must be real git log --oneline output (hex hashes); a sample lives at assets/sample_git_log.txt.

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.
