Loading the registry…
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.
20 critical findings reported by cisco-skill-scanner, agent-audit-kit, 7 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 2 sources and their verdicts differ. The worst is github (Flagged). Installing from a cleaner source does not mean the others are safe — check the source you actually install from.
github: https://github.com/coasys/ad4m, 772 findings
Claude Skills install to a single target, no runtime picker.
nerlo install -- ad4m-monorepo
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- ad4m-monorepo ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 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 388 findings across every scanner that examined this package. 13 of 20 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 9 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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.

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.

Critical command injection and credential access risks
The artifact contains critical command injection vulnerabilities in `/repo/plugins/ad4m/executor.ts` and `/repo/test-runner/src/cli.ts`, allowing for shell execution. There are also critical coercive injection findings in `/repo/plugins/ad4m/index.ts` and a critical taint finding in `rust-executor/src/lib.rs`. Additionally, high-severity findings indicate potential credential access in `rust-executor/src/wallet.rs` and `ui/src-tauri/src/encryption.rs`, alongside extensive file system access in `/repo/plugins/ad4m/config.ts` that could lead to data exfiltration.
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.
