Loading the registry…
Use when running `wmill` CLI commands — `script preview/run`, `flow run`, `job get/list/logs`, `workspace`, `version`. Triggers on "run the script", "check the job", "preview vs run", inspecting failures via `wmill job`, "wmill generate-metadata no scripts found", "wmill bootstrap", "wmill --workspace", "active workspace footgun", "script preview wrong worker tag". Covers preview-vs-run decision (no push — sync banned at Hallow), workspace flags, JSON output handling, bootstrap-before-generate-metadata for hand-written scripts, `wmill script preview` ignoring sidecar tag (nondeterministic worker routing).
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
5 critical findings reported by cisco-skill-scanner, agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'hallow-inc/claude-plugins (cli-commands)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'hallow-inc/claude-plugins (cli-commands)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
3 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 82 findings across every scanner that examined this package. None of the 5 findings rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
17 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Files:
Critical prompt injection and potential arbitrary code execution risks identified.
The artifact exhibits critical prompt injection vulnerabilities in `raw-app/SKILL.md` and `write-flow/SKILL.md`, which could lead to unintended AI model behavior. Additionally, critical findings related to potential arbitrary code execution are present in `windmill-debug/SKILL.md` and `write-script-bun/SKILL.md`. A high severity finding in `.claude-plugin/marketplace.json` also warrants attention.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
