gen-release-notes

A command that creates release notes using the Keep a Changelog format, a common structure for documenting software changes by type.

In plain words
What is it for?
Use it after a release point to summarize additions, changes, fixes, and other work between a previous Git tag and the current code.
Why use it?
It gathers commits, changed files, tags, and merged pull requests so release summaries do not have to be assembled manually.

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.

Made for: Claude Code.

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

gen-release-notes 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 2d 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.

Release Notes Generator

Generate professional release notes following the Keep a Changelog standard.

Input: Previous tag (e.g., v0.0.1)

$ARGUMENTS

Use extended thinking to analyze the changes thoroughly before generating release notes.

Step 1: Gather Changes

Run these commands to collect information about changes since the provided tag:

# Store the previous tag
PREV_TAG="$ARGUMENTS"

# Verify the tag exists
git tag -l "$PREV_TAG"

# Get the repo URL for PR links
git remote get-url origin

# List commits since last tag
git log ${PREV_TAG}..HEAD --pretty=format:"%h %s" --no-merges

# Get detailed diff stats
git diff ${PREV_TAG}..HEAD --stat

# List changed files by directory
git diff ${PREV_TAG}..HEAD --name-only | sort | uniq

Also gather PR information:

# Get merged PRs since the tag (requires gh CLI)
gh pr list --state merged --search "merged:>=$(git log -1 --format=%ci $PREV_TAG | cut -d' ' -f1)" --json number,title,author,labels

Step 2: Analyze and Categorize

Categorize each change into exactly one of these groups (in this order):

Category Include Exclude
Added New features, new public APIs, new CLI commands Internal utilities not exposed to users
Changed Modified behavior, performance improvements, updated dependencies with user impact Refactors with no behavior change
Deprecated Features marked for future removal -
Removed Deleted features, removed public APIs Removed internal code
Fixed Bug fixes, error handling improvements Test-only fixes
Security Vulnerability patches, security hardening -

Exclude entirely:

  • CI/CD configuration changes (unless they affect users)
  • Documentation-only changes (unless they reveal new features)
  • Code style/formatting changes
  • Test-only changes
  • Internal refactors with no user-visible impact
  • Merge commits

Step 3: Determine Version Number

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.
