Install

Each tab says whether it installs commit 190e05a, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Pinned to commit 190e05a, the one we checked.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/Jeffallan/claude-skills.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 190e05a380b624187f5770451e1f41b9187cb63c &&
  git -C "$tmp" sparse-checkout set -- skills/websocket-engineer &&
  git -C "$tmp" checkout -q 190e05a380b624187f5770451e1f41b9187cb63c &&
  mkdir -p .claude/skills &&
  mkdir .claude/skills/websocket-engineer &&
  cp -R "$tmp"/skills/websocket-engineer/. .claude/skills/websocket-engineer/ &&
  rm -rf "$tmp"

If Claude Code was already running and this created the skills folder, run /reload-skills.

What it can touch

From the files and frontmatter at commit 190e05a. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

  • 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.

Pattern check

Pattern check: nothing flagged · commit 190e05a · 27 Oct 2026

We checked every text file in this skill, at commit 190e05a 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.

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

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

    • Note

      Reference files over 100 lines with no table of contents at the top: references/alternatives.md (392 lines), references/patterns.md (401 lines), references/protocol.md (196 lines), references/scaling.md (334 lines) and references/security.md (480 lines). B5

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

  • 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

      Reference files over 100 lines with no table of contents at the top: references/alternatives.md (392 lines), references/patterns.md (401 lines), references/protocol.md (196 lines), references/scaling.md (334 lines) and references/security.md (480 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.
