Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.01374 |
| Opus 5 | $0.00042 | $0.00687 |
| Sonnet 5 | $0.00017 | $0.00275 |
| Haiku 4.5 | $0.00008 | $0.00137 |
Grade A, and why
generate-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 10d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate Changelog
Generate or update CHANGELOG.md by analyzing git commit history and formatting entries following the Keep a Changelog standard with automatic semantic version bumping.
Prerequisites
- Git repository with conventional commits
jqinstalled (brew install jqorapt install jq)
Settings Check
Check whether .claude/changelog-manager.local.md exists:
[ -f ".claude/changelog-manager.local.md" ] && echo "exists" || echo "missing"
If missing — invoke changelog-manager:changelog-config via Skill tool to create it. Wait for it to complete before continuing.
If exists — read the current languages and platforms values; use them as defaults in the pre-flight questions below.
Pre-flight Questions
Ask all questions at once using the AskUserQuestion tool:
- Release notes — Do you want release notes generated after the changelog is created?
- Platform(s) (only if #1 = Yes) — Which platform(s)? Show current value from settings as default.
- A. App Store
- B. Play Store
- C. Web
- Accept single or multiple answers (e.g., "A", "A and B", "all").
- Languages (only if #1 = Yes) — Which languages? Show current value from settings as default. (Locale codes in
language_REGIONformat, e.g.en_US, id_ID)
After answers, confirm selections:
Your selections:
- Release notes: Yes / No
- Platform(s): App Store / Play Store / Web (omit if release notes = No)
- Languages:
en_US, id_ID(omit if release notes = No)
Commit Analysis
Run the commit analysis script:
bash $CLAUDE_PLUGIN_ROOT/scripts/analyze-commits.sh
If the script prints No changes since last release., inform the user and stop.
The JSON output contains:
| Field | Description |
|---|---|
last_tag |
Last git tag, or v0.0.0 if none |
next_version |
Computed next semver tag |
date |
Today's date (YYYY-MM-DD) |
commits |
Array of { category, message, pr, breaking } objects |
What ships with it
2 files 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.
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.
