From the files and frontmatter at commit 0365f57. 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.

• Reaches the network

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

• 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 0365f57 · 29 Oct 2026

We checked every text file in this skill, at commit 0365f57 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

    Paths that may not work once the skill is installed: line 441: ../terraform-aws/ (outside the skill folder), line 442: ../aws-iam/ (outside the skill folder), line 443: ../aws-vpc/ (outside the skill folder), line 444: ../aws-ec2/ (outside the skill folder) and line 445: ../aws-s3/ (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

  • Note

    Reference files that SKILL.md doesn't link: references/cfn-syntax.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/cfn-syntax.md (124 lines). 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

    Paths that may not work once the skill is installed: line 441: ../terraform-aws/ (outside the skill folder), line 442: ../aws-iam/ (outside the skill folder), line 443: ../aws-vpc/ (outside the skill folder), line 444: ../aws-ec2/ (outside the skill folder) and line 445: ../aws-s3/ (outside the skill folder).

• 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

    Paths that may not work once the skill is installed: line 441: ../terraform-aws/ (outside the skill folder), line 442: ../aws-iam/ (outside the skill folder), line 443: ../aws-vpc/ (outside the skill folder), line 444: ../aws-ec2/ (outside the skill folder) and line 445: ../aws-s3/ (outside the skill folder).

    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

    Paths that may not work once the skill is installed: line 441: ../terraform-aws/ (outside the skill folder), line 442: ../aws-iam/ (outside the skill folder), line 443: ../aws-vpc/ (outside the skill folder), line 444: ../aws-ec2/ (outside the skill folder) and line 445: ../aws-s3/ (outside the skill folder). B6

    Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.

• 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

    Paths that may not work once the skill is installed: line 441: ../terraform-aws/ (outside the skill folder), line 442: ../aws-iam/ (outside the skill folder), line 443: ../aws-vpc/ (outside the skill folder), line 444: ../aws-ec2/ (outside the skill folder) and line 445: ../aws-s3/ (outside the skill folder).
