The pure JavaScript templating engine that uses handlebars.
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.
1 critical finding reported by cisco-skill-scanner. 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/nci-gis/js-tmpl, 622 findings
Claude Skills install to a single target, no runtime picker.
nerlo install -- @nci-gis/js-tmpl
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- @nci-gis/js-tmpl ~/.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 608 findings across every scanner that examined this package. None of the 1 finding rated critical by their scanner 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.
459 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.
Rules: DATA_EXFIL_JS_FS_ACCESS, LOW_ANALYZABILITY, FILE_MAGIC_MISMATCH · Files: /repo/tests/integration/full-render.test.js, /repo/tests/unit/config/loader.test.js, /repo/tests/unit/config/resolver.test.js and 11 more · reported by cisco-skill-scanner

7 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it 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.

Artifact contains critical command injection and high-risk file system access.
The artifact includes a critical command injection vulnerability in `/repo/src/engine/contentRenderer.js`, which could allow arbitrary shell execution. Additionally, there are multiple instances of high-risk file system access in various files, including `/repo/scripts/check-doc-exports.js` and `/repo/src/config/loader.js`, indicating potential for unauthorized file reads or writes. Supply chain risks are also present, as noted by `AAK-SUPPLY-001` findings in `.mcp.json`. The overall analyzability of the repository is low, hindering a complete security assessment.
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.
