From the files and frontmatter at commit 1da2195. This is how much a skill can do, not whether it is risky.

• Downloads software

  It fetches programs or packages from the internet, or from a package source other than the default.

  SKILL.md:159 (opens in a new tab)

• Installs more skills

  It tells the agent to install other skills, plugins or tool servers.

  SKILL.md:205 (opens in a new tab)

• Changes agent settings

  It writes to agent memory or settings files such as CLAUDE.md, AGENTS.md or .claude/settings.json.

  SKILL.md:175 (opens in a new tab)

• Runs shell commands

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

• Reaches the network

  It sends or fetches data over the internet, for example with curl, an HTTP library or a package install.

We checked every text file in this skill, at commit 1da2195 on 3 Nov 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 the strictest version of each rule among the agents we check.

  • Warning

    The body is 522 lines; the spec suggests under 500. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Warning

    Links to files that aren't in the skill folder: line 320: assets/. B3

    Fix: Add the missing files or correct the paths, relative to SKILL.md.

  • Note

    There is no license field, so readers can't tell whether they may reuse the skill. O2

    Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.

  • Note

    Reference files that SKILL.md doesn't link: references/error-patterns.md (linked only from references/post-deploy-checks.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/blueprint-spec.md (757 lines), references/configuration-guide.md (660 lines), references/deployment-details.md (243 lines), references/direct-creation.md (122 lines), references/runtimes.md (528 lines) and 1 more. B5

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

• Claude CodePasses with warnings

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

  • Warning

    Links to files that aren't in the skill folder: line 320: assets/. B3

    Fix: Add the missing files or correct the paths, relative to SKILL.md.

  • Note

    The body is 522 lines; the spec suggests under 500. Claude Code's docs say the same. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Note

    Reference files that SKILL.md doesn't link: references/error-patterns.md (linked only from references/post-deploy-checks.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/blueprint-spec.md (757 lines), references/configuration-guide.md (660 lines), references/deployment-details.md (243 lines), references/direct-creation.md (122 lines), references/runtimes.md (528 lines) and 1 more. B5

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

• Claude apps & API uploadPasses with warnings

  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.

  • Warning

    Links to files that aren't in the skill folder: line 320: assets/. B3

    Fix: Add the missing files or correct the paths, relative to SKILL.md.

  • Note

    The description is 319 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 522 lines; the spec suggests under 500. Anthropic's guidance says the same. B1

    Fix: Move detailed sections into reference files and link to them from SKILL.md.

  • Note

    Reference files that SKILL.md doesn't link: references/error-patterns.md (linked only from references/post-deploy-checks.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/blueprint-spec.md (757 lines), references/configuration-guide.md (660 lines), references/deployment-details.md (243 lines), references/direct-creation.md (122 lines), references/runtimes.md (528 lines) and 1 more. B5

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

• OpenAI (Codex & API)Passes with warnings

  Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.

  • Warning

    Links to files that aren't in the skill folder: line 320: assets/. B3

    Fix: Add the missing files or correct the paths, relative to SKILL.md.

• VS Code & CopilotPasses with warnings

  VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.

  • Warning

    Links to files that aren't in the skill folder: line 320: assets/. B3

    Fix: Add the missing files or correct the paths, relative to SKILL.md.
