kubb: Skill for Claude Code

.agents/skills/changelog/SKILL.md

changelog is a skill for Claude Code, Codex from kubb-labs/kubb. It costs 47 tokens per session (947 once invoked), scanned A, original, MIT.

A guide for turning Git commit history into release notes, which are customer-facing summaries of what changed in a software version.

In plain words
What is it for?
Use it to create changelogs for releases, documentation pages, or website updates, including workflows based on Changesets, a tool for tracking package version changes.
Why use it?
It translates technical commit messages into understandable updates, groups them by type, and filters out internal work that users do not need to see.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is kubb-labs/kubb's own configuration. It tells Claude Code and Codex how to work on kubb itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything kubb configures →

About the project

Kubb is a modular code-generation framework that turns OpenAPI descriptions into type-safe TypeScript code, Zod schemas, and TanStack Query integrations. It is used by TypeScript developers to generate client code and related interfaces from API specifications. The catalogue contains extensions such as skills, commands, hooks, agents, and a plugin that support Kubb workflows.

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 9d 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.

Changelog and Versioning Skill

This skill transforms technical git commits into polished, user-facing changelogs that your customers and users will understand and appreciate.

When to Use

  • Preparing release notes for a new version
  • Documenting changes for the website
  • Creating or editing documentation pages
  • Ensuring consistent writing style across content

What It Does

  1. Scans Git History: Analyzes commits from a specific time period or between versions.
  2. Categorizes Changes: Groups commits into logical categories (features, improvements, bug fixes, breaking changes).
  3. Translates Technical → User-Friendly: Converts developer commits into customer language.
  4. Formats Professionally: Creates clean, structured changelog entries following Kubb conventions.
  5. Filters Noise: Excludes internal commits (refactor, test, etc.).
  6. Follows Best Practices: Applies changelog guidelines and your brand voice.

Kubb uses Changesets for version management and maintains a comprehensive changelog in docs/changelog.md.

Changeset Workflow

Creating a Changeset

For every PR with code changes, create a changeset:

pnpm changeset

Interactive prompts:

  1. Select which packages are affected
  2. Choose version bump type (major / minor / patch)
  3. Write a concise summary of the changes

Version Bump Types

Type Description
Major (breaking) Changes that break existing functionality
Minor (feature) New features that don't break existing functionality
Patch (fix) Bug fixes and minor improvements

Changelog Format

The changelog follows a specific structure in docs/changelog.md.

  • Use ## for version headings (not #).
  • Use ### for change type sections with emoji prefixes.
  • Use #### for individual plugin names with links.

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.
