mcproc: Skill for Claude Code

.claude/skills/release/SKILL.md

release is a skill for Claude Code from neptaco/mcproc. It costs 40 tokens per session (1,020 once invoked), scanned A, original, MIT.

A release workflow for publishing a new software version from the main Git branch. It uses semantic versioning, where version changes signal breaking changes, new features, or fixes.

In plain words
What is it for?
Use it when preparing a Rust project release. It helps choose a version, run formatting, linting, and tests, update release notes and package metadata, then create and push a Git tag.
Why use it?
It provides a repeatable sequence for checking the worktree, tests, changelog, version files, commit, and release tag. This reduces missed steps during a release.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter.

This is neptaco/mcproc's own configuration. It tells Claude Code how to work on mcproc 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 mcproc 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 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 2mo 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.

リリースワークフロー

新しいバージョン $ARGUMENTS をリリースします。

前提条件

  • main ブランチにいること
  • 未コミットの変更がないこと
  • CI が通っていること

手順

1. 事前確認

# 現在のブランチとステータス確認
git branch --show-current
git status --short

未コミットの変更がある場合は、先にコミットまたは stash してください。

2. バージョン決定

引数でバージョンが指定されていない場合、以下を確認:

# 最新のタグを確認
git describe --tags --abbrev=0 2>/dev/null || echo "タグなし"

# 前回リリースからの変更を確認
git log $(git describe --tags --abbrev=0 2>/dev/null)..HEAD --oneline
Semantic Versioning ガイド
変更内容 バージョン 例
破壊的変更(BREAKING CHANGE) メジャー v1.0.0 → v2.0.0
新機能追加(feat:) マイナー v1.0.0 → v1.1.0
バグ修正(fix:) パッチ v1.0.0 → v1.0.1

3. 品質チェック

cargo fmt -- --check && cargo clippy --all-targets -- -D warnings && cargo test

4. CHANGELOG 更新

CHANGELOG.md の [Unreleased] セクションを新しいバージョンに変更:

  1. ## [Unreleased] を ## [<VERSION>] - <TODAY> に変更
  2. ファイル末尾のリンク定義を更新

5. Cargo.toml バージョン更新

ワークスペースの Cargo.toml を更新:

[workspace.package]
version = "<VERSION>"

6. 変更をコミット

git add CHANGELOG.md Cargo.toml
git commit -m "chore: bump version to <VERSION>"

7. タグ作成とプッシュ

# タグを作成
git tag -a v<VERSION> -m "Release v<VERSION>"

# コミットとタグをプッシュ(GitHub Actions が自動でリリース)
git push origin main
git push origin v<VERSION>

8. リリース確認

GitHub Actions でリリースワークフローが実行される:

  1. テスト実行
  2. クロスプラットフォームビルド(Linux x86_64/arm64, macOS x86_64/arm64)
  3. GitHub Release 作成(バイナリ添付)
# ワークフロー状態確認
gh run list --workflow=release.yml --limit 3

9. Homebrew 更新

リリースが完了したら、Homebrew Formula を更新:

# publish-homebrew ワークフローを手動実行
gh workflow run publish-homebrew.yml

または homebrew-tap リポジトリで手動更新。

10. リリース完了確認

# GitHub Release を確認
gh release view v<VERSION>

# または Web で確認
gh release view v<VERSION> --web

使用例

/release v0.1.4
/release v0.2.0
/release v1.0.0

トラブルシューティング

タグを削除したい場合

# ローカルタグ削除
git tag -d v<VERSION>

# リモートタグ削除(未リリースの場合のみ)
git push origin :refs/tags/v<VERSION>

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.
