batch-artifact-verification

batch-artifact-verification is a skill for Claude Code, Codex from makifbaysal/tasktrooper. It costs 47 tokens per session (1,018 once invoked), scanned A, original, Apache-2.0.

A procedure for verifying that a desktop or mobile release artifact was actually published and is what users will download. An artifact is the built file or package delivered to users.

In plain words
What is it for?
Use it after a batch release is waiting for a decision or has been rolled back. It checks release assets, update-feed files, stored build records, and the steps for removing a bad release tag.
Why use it?
A build can compile successfully without being published, served, or referenced by the update channel. These checks catch releases that exist in a build system but will not reach users correctly.

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

batch-artifact-verification 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Batch artifact verification

A batch release (desktop, mobile and other human-cut components) has no bound runtime environment — see post-deploy-verification's last section. Its evidence is whether the thing it built actually got published and is what users will fetch next, per executor.

github_actions / local

run_terminal("gh release view <tag> --json tagName,isDraft,isPrerelease,isImmutable,publishedAt,assets")

Expect isDraft: false, the platform's assets present with size > 0, and the update-feed file if the app ships one (e.g. latest-mac.yml). If gh is unavailable but the repository is public, fall back to fetch_url https://api.github.com/repos/<owner>/<repo>/releases/tags/<tag>.

If the repository brief names an update feed or a Homebrew cask URL, fetch_url it and confirm it names the new version — that is what actually reaches an existing install, not the GitHub Release page by itself.

For a local executor, the exit code is the first signal: local_run.exit_code == 0, with local_run.tail showing the publish step actually ran (not just that the build compiled).

store

Every entry in store_builds[] must have build != baseline_build and carry no error. A baseline_build of "?" means the baseline was never confirmed — say so rather than treating it as a pass. "Deployed" here means the build reached the internal/testing channel; promoting it to production is a human step taken in the store console, and your finish note says so explicitly rather than implying the rollout is live.

Yanking a bad batch release

This is the first manual_steps item on a batch rollback (rollback-runbook), and you perform it yourself — it is the one write release-terminal-scope allows:

run_terminal('gh release edit <tag> --prerelease --title "<name> [YANKED]"')

This works on an immutable release (title, notes and prerelease/latest stay editable; assets and the tag itself do not) and removes it from GitHub's "latest" resolution (the most recent non-prerelease, non-draft release), which most update feeds follow via /releases/latest. Then point "latest" back at the previous good release:

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.
