disable-model-invocation: true
metadata:
  framework_dependency: "mycelium"
  framework_dependency_note: "This skill is designed to run within the Mycelium framework (https://github.com/haabe/mycelium). Standalone use will skip the canvas state, theory gates, and harness behavior the skill assumes. Install: /plugin install mycelium@haabe-mycelium."

Ping (smoke-test only)

When invoked, respond with exactly this single line and nothing else:

MYCELIUM_PLUGIN_LOAD_OK

This is a plugin-shape marker, not a version assertion — it confirms the plugin packaging works end-to-end (manifest → marketplace → install → namespaced invocation). The version a user is actually running comes from `/plugin list` or `plugin.json#version`, not this marker. (The marker was previously version-suffixed, which created drift: it stayed pinned at `_v0.20.0` while plugin.json moved through 10 patches. Detected during 2026-05-09 dogfood.)

For real Mycelium skills, see the parent `skills/` directory once migration completes.

Mycelium won't make your idea good. It keeps you and your agent honest about whether it is, from first idea to market. Built on Claude Code, where the gates are structural. The files and skills port to opencode, Codex and Cursor. Outcome over output.

Questions about ping.

Which coding agents can use ping?
ping installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
