Claude Skill

Scan Haltedcomposite

Claude Code plugin marketplace for the Silas project — agents, skills, hooks, commands, rules, and rigor SDLC plugin

Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.

Source:: github.com/netsecdevio/silas-tools
Version:: 0.1.0
License:: MIT
Author:: Doug Downer
Provenance:: Found by crawling (provenance, not a security rating)

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.

265 critical findings reported by cisco-skill-scanner, agent-audit-kit, 90 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.

Install

Claude Skills install to a single target, no runtime picker.

nerlo install -- silas-tools

Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.

cp -r -- silas-tools ~/.claude/skills/

Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.

Your view:

5 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.

AI review of these findings

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.

Upheld as real: 1,084
Dismissed as false positives: 900
Not reviewed: 226

Out of 2,210 findings across every scanner that examined this package. 175 of 265 findings rated critical by their scanner were among the dismissals.

Not reviewed is not the same as clean. Those 226 findings stand exactly as their scanners reported them, at full severity, as they would have without this review.

Why those 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.

891 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

In installed code — never dismissed

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.

What the review concluded

Artifact contains critical command injection and potential credential exposure.

The artifact exhibits critical command injection vulnerabilities, particularly in JavaScript child processes and through `eval` functions, indicating a capability for shell execution. It also contains critical findings related to skill definitions and multi-cloud platform configurations, which may involve sensitive operations. Additionally, there are high-severity findings for file system access, potential credential exposure, and background process execution.

Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
