From the files and frontmatter at commit 032b4b6. This is how much a skill can do, not whether it is risky.

• Names web addresses

  It mentions outside web addresses the agent may visit. We list them but don't follow them.

  Outside links we did not follow

• Bundles scripts

  The folder holds code files the agent may run.

Pattern check: nothing flagged · commit 032b4b6 · 29 Oct 2026

We checked every text file in this skill, at commit 032b4b6 on 29 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

How the check worksReport an incorrect finding

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

• Agent Skills specPasses with warnings

  The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.

  • Warning

    The body is about 6,519 tokens (approx.); the spec suggests under 5,000. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Note

    Reference files over 100 lines with no table of contents at the top: references/actions-and-conditions.md (314 lines), references/asset-catalog.md (106 lines), references/lane-connectivity.md (122 lines), references/physics-first-design.md (174 lines), references/routes-and-points.md (179 lines) and 2 more. B5

    Fix: Add a short list of the sections at the top of each.

• Claude CodePasses

  Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

  • Note

    The body is about 6,519 tokens (approx.); the spec suggests under 5,000. After compaction Claude Code keeps only the first 5,000 tokens of a skill. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Note

    Reference files over 100 lines with no table of contents at the top: references/actions-and-conditions.md (314 lines), references/asset-catalog.md (106 lines), references/lane-connectivity.md (122 lines), references/physics-first-design.md (174 lines), references/routes-and-points.md (179 lines) and 2 more. B5

    Fix: Add a short list of the sections at the top of each.

• Claude apps & API uploadPasses

  Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.

  • Note

    The description is 446 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4

    Fix: If the claude.ai upload refuses it, trim the description to 200 characters.

  • Note

    The body is about 6,519 tokens (approx.); the spec suggests under 5,000. Anthropic's guidance says the same. B2

    Fix: Move detail into reference files that the agent reads only when needed.

  • Note

    Reference files over 100 lines with no table of contents at the top: references/actions-and-conditions.md (314 lines), references/asset-catalog.md (106 lines), references/lane-connectivity.md (122 lines), references/physics-first-design.md (174 lines), references/routes-and-points.md (179 lines) and 2 more.

    Fix: Add a short list of the sections at the top of each.
