release

release is a skill for Claude Code, Codex from yoshiko-pg/difit. It costs 61 tokens per session (647 once invoked), scanned A, original, MIT.

A release procedure for the difit software project. It turns commits since the latest version tag into a categorized Unreleased section in the changelog, then publishes it after confirmation in Japanese.

In plain words
What is it for?
Use it when the user asks to cut a release or says “リリース.” It prepares the changelog, requests explicit approval, and then completes the release steps.
Why use it?
It reduces the manual work and mistakes involved in summarizing changes and ensures the confirmed changelog text is used for the release.

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 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.

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.

Release Workflow

Follow this workflow for the current repository.

Prepare changelog draft

  1. Run ./scripts/get-changes-since-tag.sh.
  2. Categorize changes into these sections as needed: Added, Changed, Deprecated, Removed, Fixed, Security, Thanks.
  3. Use script output rules:
    • Use GitHub username from script output.
    • Exclude yoshiko-pg and renovate[bot] from Thanks.
    • Include PR numbers when available.
    • Order bullets with PR numbers by ascending PR number within each section, and list multiple PR numbers within a bullet in ascending order.
    • Use commit subject and body for categorization.
    • Consolidate routine dependency-only updates, including grouped dependency updates, package manager bumps, and ordinary individual dependency bumps, into a single Changed bullet formatted as - Update dependencies (#123 #124 #125); keep a separate bullet only when the dependency change is clearly user-facing beyond routine maintenance.
  4. Write the categorized content into CHANGELOG.md under ## [Unreleased].
  5. Ask for user confirmation in Japanese.

Release after explicit OK

  • The only allowed CHANGELOG.md edits after OK are:
    • insert the new version heading with today's date directly below ## [Unreleased]
    • place the captured Unreleased body under that new heading unchanged
    • leave ## [Unreleased] empty
    • update the bottom compare links for Unreleased and the new version
  1. Run npm version --no-git-tag-version patch.
  2. Move current Unreleased content into a new version section with today's date.
  3. Update bottom links:
    • Update Unreleased compare link to new version tag.
    • Add compare link for the new version.
  4. Commit CHANGELOG.md and package.json with an English message: chore: release vX.Y.Z.
  5. Create tag vX.Y.Z.
  6. Push main and tags: git push origin main --tags.
  7. If push is rejected by non-fast-forward:
    • Run git pull --rebase origin main.
    • Retry git push origin main --tags.
  8. Build release notes from the new version section text in CHANGELOG.md.
  9. Create GitHub release on origin:
    • gh release create vX.Y.Z --title "vX.Y.Z" --notes-file <notes-file>

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
