From the files and frontmatter at commit 896390f. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

• Runs shell commands

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

  SKILL.md:2 (opens in a new tab)

  name: Excel工具

We checked every text file in this skill, at commit 896390f on 27 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 specFails

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

  • Error

    The name "Excel工具" has uppercase letters. Names may use only a–z, 0–9 and single hyphens. N3

    Fix: Use only lowercase letters, digits and single hyphens.

  • Error

    The name "Excel工具" doesn't match its folder "xlsx". The spec requires them to match. N4

    Fix: Set name: xlsx, or rename the folder to Excel工具.

  • Warning

    Contains non-Latin letters: "工" (U+5DE5) and "具" (U+5177) in "Excel工具". The spec's validator accepts letters from other alphabets, but Anthropic's does not, and some look exactly like Latin letters, so a name can pass for another skill's. N3

    Fix: Write the name with only a–z, 0–9 and hyphens.

  • 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

    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.

• 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

    Contains non-Latin letters: "工" (U+5DE5) and "具" (U+5177) in "Excel工具". Claude Code loads it, but some letters from other alphabets look exactly like Latin ones, so a name can pass for another skill's. N3

    Fix: Write the name with only a–z, 0–9 and hyphens.

  • Note

    The name "Excel工具" doesn't match its folder "xlsx". Claude Code shows the skill as /Excel工具, and the folder name also invokes it. N4

    Fix: Set name: xlsx, or rename the folder to Excel工具.

• Claude apps & API uploadFails

  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.

  • Error

    The name "Excel工具" has uppercase letters. Anthropic's validator allows only lowercase letters, digits and hyphens. N3

    Fix: Use only lowercase letters, digits and single hyphens.

  • Error

    Contains non-Latin letters: "工" (U+5DE5) and "具" (U+5177) in "Excel工具". Anthropic's validator allows only lowercase letters, digits and hyphens. N3

    Fix: Write the name with only a–z, 0–9 and hyphens.

  • Error

    The name "Excel工具" doesn't match its folder "xlsx". claude.ai refuses an upload whose folder name doesn't match the skill name. N4

    Fix: Set name: xlsx, or rename the folder to Excel工具.

• OpenAI (Codex & API)Fails

  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.

  • Error

    The name "Excel工具" has uppercase letters. OpenAI's upload follows the spec, which allows only a–z, 0–9 and hyphens. N3

    Fix: Use only lowercase letters, digits and single hyphens.

  • Error

    Contains non-Latin letters: "工" (U+5DE5) and "具" (U+5177) in "Excel工具". OpenAI's upload follows the spec, which allows only a–z, 0–9 and hyphens. N3

    Fix: Write the name with only a–z, 0–9 and hyphens.

  • Warning

    The name "Excel工具" doesn't match its folder "xlsx". OpenAI's own upload example uses a differently named folder, but the spec it follows says they must match. N4

    Fix: Set name: xlsx, or rename the folder to Excel工具.

• VS Code & CopilotFails

  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.

  • Error

    Contains non-Latin letters: "工" (U+5DE5) and "具" (U+5177) in "Excel工具". VS Code's docs say a name with characters other than lowercase letters, digits and hyphens fails to load. N3

    Fix: Write the name with only a–z, 0–9 and hyphens.

  • Warning

    The name "Excel工具" has uppercase letters. VS Code uses the folder name whenever the name differs from it. N3

    Fix: Use only lowercase letters, digits and single hyphens.

  • Warning

    The name "Excel工具" doesn't match its folder "xlsx". VS Code uses the folder name, xlsx, instead. N4

    Fix: Set name: xlsx, or rename the folder to Excel工具.
