buildkite-mcp-server: Skill for Claude Code

.agents/skills/release-notes/SKILL.md

release-notes is a skill for Claude Code, Codex from buildkite/buildkite-mcp-server. It costs 47 tokens per session (692 once invoked), scanned A, original, MIT.

A release-note drafting guide for GitHub, the code-hosting service, focused on versioned builds of this repository. It gathers changes and checks source details before producing maintainer-reviewed notes.

In plain words
What is it for?
Use it to prepare, review, or revise a GitHub release for a specific version, including its changes, tool updates, and user-facing outcomes.
Why use it?
It avoids relying on pull request titles or incomplete local tags, which can lead to inaccurate release information. It also keeps release notes distinct from changelogs and ordinary pull request descriptions.

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

This is buildkite/buildkite-mcp-server's own configuration. It tells Claude Code and Codex how to work on buildkite-mcp-server 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 buildkite-mcp-server configures →

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 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 15d 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

Produce accurate, maintainer-reviewed GitHub release notes that follow the style of recent curated releases in this repository.

Gather evidence

  1. Confirm the target version and inspect its current GitHub release, if one exists.
  2. Identify the comparison base from the release series and verify the full comparison range. Do not rely only on locally fetched tags.
  3. Inspect a recent curated release, such as v1.27.0, for layout and level of detail. Treat it as a style reference, not a fixed template.
  4. Collect every pull request in the comparison range. Read the pull request descriptions and changed files for user-facing changes. Inspect source at the target tag when needed to verify tool names, arguments, defaults, limits, and behavior.

Use gh for GitHub data when available. Do not infer technical details from pull request titles alone.

Draft the release

Start with a short paragraph describing the most important user outcomes. Then use the following sections when they have relevant content:

  • ## What's Changed, with concise categories such as Features, Agent Guidance, Development and Evals, and Dependencies.
  • ## Tool Changes, kept brief. For each new tool, give its name, toolset, a one-line purpose, and its required scope, destructive status, and read-only mode availability. Describe changes to existing tools in more detail when callers could see different results, such as a changed default. Leave out arguments, response fields, states, and validation rules that the tool description already gives agents.
  • ## New Contributors, when applicable.
  • A **Full Changelog** comparison link as the final line.

For each pull request in What's Changed, preserve its title, author attribution, and URL. Ensure every pull request in the comparison range appears exactly once in those categorized lists. The narrative Tool Changes section may discuss the same work without repeating attribution.

Prefer concise, factual language. Focus on externally observable behavior and agent outcomes. Exclude implementation detail unless it explains a limit, compatibility constraint, or operational risk. Do not use em dashes.

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.
