Standalone security vulnerability scanner for source code
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.
36 critical findings reported by cisco-skill-scanner, agent-audit-kit, 20 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- throughline
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 82 findings across every scanner that examined this package. 16 of 36 findings rated critical by their scanner were among the dismissals.
Not reviewed is not the same as clean. Those 32 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.
20 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.

Critical command injection and credential access risks.
This artifact contains multiple critical command injection vulnerabilities, enabling shell execution through `eval`, child processes, and function constructors in files such as `/repo/src/engine/ai-analyzer.ts` and `/repo/src/engine/incremental.ts`. A critical taint vulnerability is also present in `src/rules/web/index.ts`. High-severity findings indicate potential credential access, including hardcoded secrets in `src/engine/entropy-scanner.ts` and `src/engine/incremental.ts`, and Anthropic SDK usage in `src/index.ts`. Further findings suggest network egress and file system access capabilities.
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.
