changelog

changelog is a command for coding agents from littlebearapps/pitchdocs. It costs 14 tokens per session (443 once invoked), scanned A, original, MIT.

A command that creates or updates CHANGELOG.md from Git history. A changelog is a reader-facing list of what changed between software releases.

In plain words
What is it for?
Use it to generate the Unreleased section, document a tagged version, or rebuild the full changelog from release tags, commits, issues, and pull requests.
Why use it?
Commit messages are often written for developers and may not explain the benefit to users. This command groups changes into standard categories and rewrites them in user-focused language.

Command

Part of the pitchdocs plugin — 16 skills, 15 commands, 4 agents shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/littlebearapps/pitchdocs/changelog
Clone the repo
git clone --depth 1 https://github.com/littlebearapps/pitchdocs

Or install pitchdocs, the plugin that ships this one along with the rest of its 16 skills, 15 commands, 4 agents.

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 5d 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

/changelog

Generate or update CHANGELOG.md using conventional commits and user-benefit language.

Behaviour

  1. Load the changelog skill for format and language rules
  2. Load the doc-standards rule for tone
  3. If GitHub MCP tools are unavailable (GitLab/Bitbucket), gather equivalent data via glab CLI, REST API, or git history. Load platform-profiles for compare URL patterns.
  4. Analyse git history:
    • Parse conventional commit messages
    • Identify tagged releases
    • Map commits to issues/PRs
  5. Classify changes into Keep a Changelog categories
  6. Rewrite commit messages in user-benefit language
  7. Generate or update CHANGELOG.md

Arguments

  • No arguments: generates/updates the [Unreleased] section only
  • Version (e.g., 1.3.0): generates entry for a specific version from tag
  • full: regenerates the entire changelog from all tags

Language Transformation

Input (git log):

feat: add marketing-friendly readme generation (#42)
fix: resolve badge URL encoding for special characters (#35)
refactor: extract template engine into separate module

Output (CHANGELOG.md):

### Added
- You can now generate READMEs with marketing-friendly language (#42)

### Fixed
- Badge URLs no longer break when repos contain special characters (#35)

Note: The refactor is excluded — it's internal and doesn't affect users.

Output

Writes directly to CHANGELOG.md. Preserves existing entries when updating.

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.
