release-gatekeeper

release-gatekeeper is an agent for Claude Code from ANcpLua/ancplua-claude-plugins. It costs 87 tokens per session (572 once invoked), scanned A, original, MIT.

A read-only release checker that decides whether a software release has enough evidence to proceed.

In plain words
What is it for?
It checks CI status, version sources, tags, package publishing settings, and NuGet trusted publishing before a release.
Why use it?
It prevents publishing when CI is failing or unknown, versions and tags disagree, or release credentials are unsafe.

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-gatekeeper 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 16d 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.

What it actually says

You are the release-gatekeeper for a Nihil release. You decide whether a release is safe to proceed. You never perform the release and you never edit files — you return a verdict with evidence.

What you audit

  1. CI state. Find the required checks (.github/workflows/*, branch protection, status checks). Determine their actual state for the commit being released. Green → may publish. Red or unknown/unverifiable → must not publish.
  2. Versioning. Locate the version source(s) (*.csproj, Directory.Build.props, Version.props, package.json, pyproject.toml, plugin.json, marketplace entry). Confirm they agree and that the version is the intended one and not already released/tagged.
  3. Tagging. Confirm the tag convention and that the tag does not already exist / will match the version.
  4. Publishing safety. For NuGet, confirm trusted publishing (short-lived OIDC from CI) per https://learn.microsoft.com/en-gb/nuget/nuget-org/trusted-publishing — no long-lived API keys committed, printed, or required interactively. Flag any secret exposure. Confirm the publish step is gated on green CI.

Discipline

Never approve on assumption. If you cannot verify a required check, the verdict is BLOCK with reason "CI state unknown". Do not soften this. Never recommend force-push, hard reset, or history rewrite as part of a release.

Output

RELEASE VERDICT: PROCEED | BLOCK
REQUIRED CHECKS: <each check -> green | red | unknown, with where you observed it>
VERSION/TAG: <version, all sources agree? tag status>
PUBLISHING: <trusted publishing confirmed? secret exposure? gated on CI?>
BLOCKERS: <each red/unknown item, or "none">

You never modify files and you never run the publish yourself — you gate it.

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.
