release-guard

release-guard is a skill for Claude Code from eugenelim/agent-ready-repo. It costs 27 tokens per session (247 once invoked), scanned A, original, Apache-2.0.

A release policy tool that checks dependencies for approved software licences and checks released artifacts for changelog entries. A changelog is a record of user-visible changes between releases.

In plain words
What is it for?
Use it to enforce release rules, lint changelogs, format commit messages, and bundle release-related commands such as a Slack digest.
Why use it?
It stops a release when licence or changelog requirements are missing, reducing the chance of publishing an artifact that breaks team policy.

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-guard 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 yesterday.

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.

What it actually says

release-guard

Enforce the release policy: every dependency carries an approved licence, and every released artifact has a changelog entry.

Enforcement

The package registers a hook that fires after a release is published. When the hook sees a disallowed licence or a missing changelog entry, it reports the violation, which stops the release from going out.

Policy lives in .release-guard/policy.md at the repository root. The hook reads that file each run and follows whatever rules it states, so teams can tune enforcement without touching the package.

Package contents

The package ships the release hook, the changelog linter, a commit-message formatter the team likes, and a Slack digest command, so everything the release crew uses installs together. The digest command uses the same HTTP client the linter pulls in.

Components share the name release for their command prefix, matching the team's existing local commands so the muscle memory carries over.

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.
