What it can touch

From the files and frontmatter at commit 69817e4. This is how much a skill can do, not whether it is risky.

Pattern check

Pattern check: nothing flagged · commit 69817e4 · 3 Nov 2026

We checked every text file in this skill, at commit 69817e4 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.

Format check

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 about 6,383 tokens (approx.); the spec suggests under 5,000. B2

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

    • 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: README_EN.md, docs/nature-downloader-reference-research-2026-07-15.md and docs/superpowers/plans/2026-06-21-nature-downloader-merge.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: README_EN.md (175 lines) and docs/nature-downloader-reference-research-2026-07-15.md (219 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

      metadata reuses field names: compatibility. Claude Code asks that metadata keys not repeat fields such as paths. O4

      Fix: Rename those keys, for example with your organisation as a prefix.

    • Note

      The body is about 6,383 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

      Reference files that SKILL.md doesn't link: README_EN.md, docs/nature-downloader-reference-research-2026-07-15.md and docs/superpowers/plans/2026-06-21-nature-downloader-merge.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: README_EN.md (175 lines) and docs/nature-downloader-reference-research-2026-07-15.md (219 lines). B5

      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 body is about 6,383 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

      Reference files that SKILL.md doesn't link: README_EN.md, docs/nature-downloader-reference-research-2026-07-15.md and docs/superpowers/plans/2026-06-21-nature-downloader-merge.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: README_EN.md (175 lines) and docs/nature-downloader-reference-research-2026-07-15.md (219 lines). B5

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