release-prep

release-prep is a skill for Claude Code, Codex from ayutaz/piper-plus. It costs 79 tokens per session (2,317 once invoked), scanned A, original, MIT.

A release preparation checker for projects published through package registries, which are services that distribute software packages. It compares versions in project files, reviews the unreleased changelog section, and checks the latest published versions.

In plain words
What is it for?
Use it to inspect versions for selected runtimes or all supported runtimes, compare them with the project’s release specification, check published versions on registries such as PyPI and npm, and prepare a changelog version update.
Why use it?
It gathers release information that would otherwise need to be checked across several files and registries. It presents suggested changelog changes for confirmation instead of applying them automatically.

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-prep scanned grade A with 1 finding 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 4d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Release Preparation Helper

リリース作業の forensic checkCHANGELOG 移行支援 を 1 つにまとめた skill。手動でやると忘れがちな以下 4 段階を 1 コマンドで通す:

  1. 各 manifest の 現在の version を一覧化 (7 runtime × 9 manifest)
  2. release-versions.tomlexpected_prefix との照合
  3. CHANGELOG.md [Unreleased] の内容と、リリース時に必要な 昇格作業 の提案
  4. 公開 registry (PyPI / crates.io / NuGet / npm / Maven Central) の 最新公開 version 取得

実装は read-mostly — 変更提案は markdown diff 形式でユーザに提示し、 適用は明示確認後 (memory feedback_merge_caution.md に従う)。

引数

  • $ARGUMENTS 空: 全 runtime を一覧
  • python / rust / csharp / npm / swift / kotlin: 特定 runtime のみ
  • --target-version X.Y.Z: 次回リリース予定 version (CHANGELOG 移行提案に使う)

現在の状態

  • ブランチ: !git rev-parse --abbrev-ref HEAD
  • 引数: $ARGUMENTS
  • canonical truth: !grep -A1 "^\\[meta\\]" docs/spec/release-versions.toml | head -5

フェーズ 1: Manifest version 一覧

以下の 9 manifest を並列で Read し、現在の version を抽出して表化:

Runtime Manifest 抽出キー
Python (PyPI) VERSION ファイル全体
Rust (crates.io) src/rust/Cargo.toml [workspace.package].version
C# Core (NuGet) src/csharp/PiperPlus.Core/PiperPlus.Core.csproj <Version>
C# Cli (NuGet) src/csharp/PiperPlus.Cli/PiperPlus.Cli.csproj <Version>
npm synthesis src/wasm/openjtalk-web/package.json .version
npm g2p src/wasm/g2p/package.json .version
Swift synthesis Package.swift let version =
Swift G2P Package.swift let g2pVersion =
Kotlin Android android/gradle.properties VERSION_NAME=
# 例: rust workspace version
grep -A1 "^\[workspace.package\]" src/rust/Cargo.toml | grep "^version" | head -1

フェーズ 2: Expected prefix との照合

docs/spec/release-versions.toml を tomllib で読み、各 manifest の expected_prefix を取得。フェーズ 1 の実 version が prefix で始まるかを照合:

| Runtime | Manifest version | expected_prefix | Status |
|---------|------------------|-----------------|--------|
| Python  | 1.12.0           | 1.12.           | ✓      |
| Rust    | 0.4.0            | 0.4.            | ✓      |
| C# Core | 0.3.0            | 0.3.            | ✓      |
| ...     | ...              | ...             | ...    |

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.
