  • DevOps & Cloud work in your project

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Release is an agent skill from proshunsuke/colmsg. colmsg のバージョンリリースを計画・準備・公開するときに、互換性判断、リリースPR、GitHub Release、配布先更新の手順を適用する。

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud. It works with GitHub, Rust, Homebrew and GitHub Actions. The repository describes itself as: A CLI tool for '櫻坂46メッセージ', '日向坂46メッセージ', '乃木坂46メッセージ', '齋藤飛鳥メッセージ', '白石麻衣メッセージ', and 'yodel' app. The licence is MIT.

When your agent uses it

  • DevOps & Cloud work in your project

Example prompts

  • “/release”

What it can do on your machine

Read from SKILL.md and the folder at commit 09d15b6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Release loads about 361 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 52 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~21
When it runs · the whole SKILL.md, loaded when a task matches
~361

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

colmsg のリリース

このスキルは、colmsg の次回リリースを計画・準備・公開する依頼に使う。通常の機能PRや、リリースと無関係な変更には適用しない。

変更内容とバージョンを決める

  • 最新のGitHub Releaseとタグを確認し、そこから現在の main までに入った変更を調べる。
  • CLIのオプションと表示、保存ファイルの形式、公開Rust APIを利用者向けインターフェースとして扱う。これらに互換性のない変更があれば、SemVerのメジャーバージョン更新を検討する。
  • 既存の CHANGELOG.md と過去のリリースPRを参考に、変更点、破壊的変更、利用者が必要とする移行手順をまとめる。

リリースPRを作る

  • main の変更を取り込んだリリースブランチを使う。ブランチ名は release/vX.Y.Z とする。
  • Cargo.toml のパッケージバージョンと Cargo.lock の colmsg バージョンを一致させる。
  • CHANGELOG.md の先頭に新バージョンの節を追加する。互換性に影響する変更と移行方法は明示する。

GitHub Releaseを作る

  • Releaseワークフロー は workflow_dispatch で実行する。バージョンは Cargo.toml から読み取られ、ワークフローがタグとGitHub Releaseを作成するため、手動でタグを作らない。
  • タグが既に存在する場合は処理を止め、既存タグとReleaseの状態を調べる。既存リリースを上書きしたり、別バージョンのタグを使ったりしない。
  • 公開後、GitHub Releaseのタイトル、生成されたリリースノート、5つの配布アーカイブを確認する。自動生成ノートに破壊的変更や移行方法が載っていなければ、Release本文に追記する。

HomebrewとAUR

  • Homebrew更新ワークフロー と AUR更新ワークフロー は、GitHub Release公開後に個別実行する。両方とも最新Releaseを参照する。
  • 更新を依頼された場合に実行する。
  • GitHub Releaseの依頼だけでは、HomebrewやAURの別リポジトリ更新まで依頼されたとは扱わない。明示的な依頼がなければ、更新手順を案内して止める。

操作範囲

  • リリースの評価・計画・PR準備だけを依頼された場合、Releaseやパッケージ更新のワークフローを実行しない。
  • 公開が明示的に依頼されている場合も、まず変更内容、バージョン、CI結果を確認してから公開する。
  • 作業ツリーに既存の変更がある場合は保持し、ユーザーの明示的な指示なしに破棄しない。
