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

• Runs shell commands

  Its instructions or files give the agent commands to run on your computer.

• 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

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

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

  • Note

    The description doesn't say when to use the skill. D6

    Fix: Add a sentence such as "Use when …" naming the requests or files that should trigger it.

  • Note

    Reference files that SKILL.md doesn't link: references/write-c-interop.md (linked only from references/write-codegen-ready.md), references/write-core-constraints.md (linked only from references/write-codegen-ready.md), references/write-numerical-style.md (linked only from references/write-codegen-ready.md), references/write-performance.md (linked only from references/write-codegen-ready.md) and references/write-temporal-types.md (linked only from references/write-codegen-ready.md). Anthropic suggests linking every reference file directly from SKILL.md. B4

    Fix: Link each one from SKILL.md and say when to read it.

  • Note

    Reference files over 100 lines with no table of contents at the top: references/accelerate-mex.md (205 lines), references/generate-code.md (290 lines), references/refine-config.md (199 lines), references/verify-code.md (242 lines), references/write-c-interop.md (134 lines) and 7 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

    Reference files that SKILL.md doesn't link: references/write-c-interop.md (linked only from references/write-codegen-ready.md), references/write-core-constraints.md (linked only from references/write-codegen-ready.md), references/write-numerical-style.md (linked only from references/write-codegen-ready.md), references/write-performance.md (linked only from references/write-codegen-ready.md) and references/write-temporal-types.md (linked only from references/write-codegen-ready.md). Anthropic suggests linking every reference file directly from SKILL.md. B4

    Fix: Link each one from SKILL.md and say when to read it.

    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 921 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.
