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

release-notes-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 today.

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 comprehensive release notes in 3 formats from git commits.

Workflow

  1. Analyze git history since last release tag or specified version
  2. Fetch PR details (titles, descriptions, labels) via gh api
  3. Categorize changes into features, bug fixes, improvements, security, breaking changes
  4. Generate 3 outputs: CHANGELOG.md section (technical), PR release body (semi-technical), Slack message (user-friendly)
  5. Transform language from technical jargon to accessible messaging
  6. Alert on migrations if database migrations are detected

How to Use

Basic Usage

Generate release notes since last release
Create release notes for version 0.18.0

With Specific Range

Generate release notes from v0.17.0 to HEAD

Preview Only

Preview release notes without writing files

Output Formats

1. CHANGELOG.md Section

Technical format for developers:

## [0.18.0] - 2025-12-08

### Objective
[1-2 sentence summary]

### New Features
#### [Feature Name] (#PR)
- **Description**: ...
- **Impact**: ...

### Bug Fixes
- **[Module]**: Description (#issue, [error-tracker] ISSUE-XX)

### Technical Improvements
#### Performance / UI/UX / Architecture
- [Description]

### Database Migrations
[If applicable]

### Statistics
- PRs: X
- Features: Y
- Bugs: Z

2. PR Release Body

Uses template from .github/PULL_REQUEST_TEMPLATE/release.md:

  • Objective summary
  • Features with specs links
  • Bug fixes with error tracker references
  • Improvements by category
  • Migration instructions
  • Deployment checklist

3. Slack Announcement

Product-focused format from .github/COMMUNICATION_TEMPLATE/slack-release.md:

  • PR link included for traceability
  • Non-technical language
  • Focus on user impact (end-users, admins, stakeholders)
  • Emojis for readability
  • Statistics summary

Workflow Integration

This skill integrates with the release workflow:

1. Analyze commits: git log <last-tag>..HEAD
2. Determine version number (MAJOR.MINOR.PATCH)
3. Generate 3 outputs
4. Create PR develop -> main with "Release" label
5. Update CHANGELOG.md
6. After merge: create git tag
7. Generate Slack announcement

Files

What ships with it

7 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.

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.
