Release Prep

What it does

When your agent uses it

• Tasks that involve Changelog and release notes

Example prompts

• “/release-prep”

Requirements

• Python 3
• Pre-approved tools (allowed-tools): Bash(cat *), Bash(grep *), Bash(jq *), Bash(curl -s *), Bash(npm view *), Bash(git diff *), Bash(git log *), Bash(git status *), Bash(rg *), Read, Edit, Grep

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 05fc503. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(cat *)
  • Bash(grep *)
  • Bash(jq *)
  • Bash(curl -s *)
  • Bash(npm view *)
  • Bash(git diff *)
  • Bash(git log *)
  • Bash(git status *)
  • Bash(rg *)
  • Read

  …and 2 more on the same allowed-tools line.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl
  • jq
  • npm
  • git

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • crates.io
  • api.nuget.org
  • pypi.org
  • search.maven.org

  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 Prep loads about 1.6k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 415 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~52

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

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

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.
