Loading the registry…
Use when designing or running anything that iterates without a human in the inner loop — a /loop, a dynamic Workflow fan-out, an overnight headless `claude -p` run, a maker/checker subagent pair, worktree parallelism, or any task whose "done"/goal you intend to express as a machine-checkable condition. Triggers on "set up a loop", "run this overnight", "create a workflow to…", "let it iterate until…", "goal/done-condition", "fan out agents", "parallelize with worktrees".
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.
8 critical findings reported by cisco-skill-scanner, 6 of them in the installed artifact. 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 -- 'wilrf/agent-markdowns (engineering-agent-loops)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'wilrf/agent-markdowns (engineering-agent-loops)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 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 62 findings across every scanner that examined this package. None of the 8 findings rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 6 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.
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 data exfiltration risks
The artifact contains critical command injection vulnerabilities in `extract-frames.mjs`, allowing for shell execution. It also has high-severity findings for file system access in `capture-interaction.mjs`, indicating potential for data exfiltration. Additionally, there are high-severity issues related to marketplace configuration in `.claude-plugin/marketplace.json`.
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.
Showing 25 of 34; the rest are in the per-scanner reports above.
