Un-Default — inclusive language review for AI-generated and human copy (CLI, MCP, GitHub Action, extension). npm name is anti-default because un-default is blocked by an unrelated package.
The publisher performed an authenticated act of publication — proving control of a namespace in the official MCP registry, or appearing in a first-party catalogue an operator curates. That establishes WHO published it. It is not a security finding, and attested artifacts carry Flagged verdicts too.
16 critical findings reported by cisco-skill-scanner. The composite score alone does not reflect this — read the per-scanner reports below.
npm: anti-default @ 0.5.4, 0 findings
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- anti-default
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
7 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 98 findings across every scanner that examined this package. None of the 16 findings rated critical by their scanner were dismissed.
Not reviewed is not the same as clean. Those 1 finding 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.
6 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

1 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.

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 secret exposure risks identified.
The artifact contains critical command injection vulnerabilities in JavaScript files such as `/repo/scripts/analyze-code.ts`, `/repo/scripts/analyze-urls.ts`, `/repo/scripts/check-package.mjs`, and `/repo/scripts/preflight-release.mjs`, which could lead to shell execution. A high-severity finding indicates potential credential access and network egress from `/repo/host/telemetry_store.py`. Additionally, high-severity supply chain findings are present in `.mcp.json` and `.claude-plugin/marketplace.json`.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Showing 25 of 28; the rest are in the per-scanner reports above.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
