release-prep

release-prep is a skill for Claude Code, Codex from noah-hrbth/agent-tool-sync. It costs 63 tokens per session (861 once invoked), scanned A, original, MIT.

A release checklist for Go projects that checks the repository state, reviews commits since the last version tag, suggests the next semantic version, and creates a test build.

In plain words
What is it for?
Use it to prepare a release-readiness report, group changes for the changelog, propose a major, minor, or patch version, and run a snapshot build.
Why use it?
It gathers the information needed before a release and reduces mistakes in versioning or release notes. Publishing the release still requires manual approval.

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 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 3d 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 Prep

Goal: produce a release-readiness report and a proposed version bump for the user to approve. Never tag, push, or invoke goreleaser release (non-snapshot) yourself — those actions affect remotes and are out of scope.

Procedure

1. Confirm clean state

git status --porcelain
git rev-parse --abbrev-ref HEAD

Abort with a clear message if there are uncommitted changes or the branch is not main. Releases should cut from a clean main.

2. Identify the current and previous tag

git describe --tags --abbrev=0    # latest tag, e.g. v0.4.2
git tag --sort=-v:refname | head -5

3. Summarize commits since the last tag

git log <last-tag>..HEAD --pretty=format:'%h %s'

Group the output by the changelog regex groups in .goreleaser.yaml (Features = ^.*feat[(\w)]*:+.*$, Bug fixes = ^.*fix[(\w)]*:+.*$, Refactors = ^.*refactor[(\w)]*:+.*$, Other = everything not excluded by ^docs:, ^chore:, ^test:, ^ci:, ^style:).

4. Propose the next version

Apply conventional-commit semver inference:

  • Any feat!: / BREAKING CHANGE: → bump major.
  • Any feat: (and no breaking) → bump minor.
  • Only fix: / refactor: / chore: → bump patch.
  • No commits since last tag → no release; report and stop.

State the proposed version and the rule that produced it.

5. Validate the goreleaser config

make release-check        # runs `goreleaser check`

Surface any errors verbatim.

6. Build a snapshot

make release-snapshot     # goreleaser release --snapshot --clean --skip=publish

This validates that the build pipeline (builds, archives, homebrew_casks rendering) succeeds locally without publishing. Then list dist/ and confirm the expected per-OS/per-arch archives are present:

ls dist/

7. Report

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.
