Release Changelog Harness

What it does

When your agent uses it

• Shipping MCP/CLI without clone
• Meta repos that only ship skills via npx skills—not domain app tutorials

Example prompts

• “Use the release-changelog-harness skill to choose ecosystem-native release and changelog tooling (Changesets, Melos, release-plz) plus binary…”
• “/release-changelog-harness”

Requirements

• Node.js
• A credential in GITHUB_TOKEN

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1Classify the repo
2. 2Choose generator (ADR if non-obvious)
3. 3Wire harness surfaces
4. 4Minimal Changesets shape (JS monorepos and private packages)
5. 5Choose distribution surface
6. 6Verify legibility

What it can do on your machine

Read from SKILL.md and the folder at commit 62f3ee1. 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

  Shell commands in SKILL.md call:

  • pnpm
  • npx
  • git
  • changeset
  • dart

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

• Network

  Links to these hosts (documentation or services it may open):

  • github.com
  • melos.invertase.dev

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

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • GITHUB_TOKEN

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

Context cost

Release Changelog Harness loads about 2.6k tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 1,017 words of instructions outside code blocks.

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

~94

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

~2.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~7.2k

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.
