quality-nonconformance

From the files and frontmatter at commit b38be6a. 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.

Pattern check: nothing flagged · commit b38be6a · 3 Nov 2026

We checked every text file in this skill, at commit b38be6a 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

    Fields outside the spec: homepage. Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1

    Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.

  • Warning

    metadata values should be text; clawdbot (a map) is not. The spec's validator turns them into text; other readers may not. O4

    Fix: Quote each value, for example version: "1.0".

  • Warning

    The body is about 7,389 tokens (approx.); the spec suggests under 5,000. B2

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

  • Note

    The first sentence of the description is 270 characters. Agents shorten long descriptions, so lead with the main job. D8

    Fix: Start with one short sentence that names the job.

  • Note

    Line 76 has dated wording ("by 2025"), which goes stale. B8

    Fix: Describe the current way, and move old patterns into their own clearly marked section.

• 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 first sentence of the description is 270 characters. Agents shorten long descriptions, so lead with the main job. D8

    Fix: Start with one short sentence that names the job.

  • Note

    Claude Code ignores fields it doesn't know: homepage. O1

    Fix: Check the spelling against Claude Code's field list, or delete them.

  • Note

    The body is about 7,389 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

    Line 76 has dated wording ("by 2025"), which goes stale. B8

    Fix: Describe the current way, and move old patterns into their own clearly marked section.

• 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

    Upload and packaging fail on fields outside the spec: homepage. O1

    Fix: Delete them, and keep your own data under metadata as text values.

  • Note

    The description is 419 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

    metadata values should be text; clawdbot (a map) is not. The spec defines metadata as text to text. O4

    Fix: Quote each value, for example version: "1.0".

  • Note

    The body is about 7,389 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

    Line 76 has dated wording ("by 2025"), which goes stale. B8

    Fix: Describe the current way, and move old patterns into their own clearly marked section.

• 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

    Fields outside the spec: homepage. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1

    Fix: Delete them, or move your own data under metadata as text values.

  • Warning

    metadata values should be text; clawdbot (a map) is not. OpenAI's upload follows the spec's text-to-text rule. O4

    Fix: Quote each value, for example version: "1.0".

  • Note

    The first sentence of the description is 270 characters. Agents shorten long descriptions, so lead with the main job. D8

    Fix: Start with one short sentence that names the job.

• VS Code & CopilotPasses

  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.

  • Note

    VS Code ignores fields it doesn't support: homepage. O1

    Fix: Delete them unless another agent you target reads them.
