// MDA compatibility demonstration skill for Codex CLI. Compiled from compat/codex-cli/source.mda. Loading this skill confirms that an MDA-emitted SKILL.md is discovered and parsed by Codex CLI with the envelope subset of agentskills.io v1 fields honored.
MDA compatibility demonstration skill for Hermes Agent. Compiled from compat/hermes/source.mda. Loading this skill confirms that an MDA-emitted SKILL.md is discovered, parsed, and listed by Hermes Agent under its `~/.hermes/skills/<category>/<name>/SKILL.md` layout.
MDA compatibility demonstration skill for OpenClaw. Compiled from compat/openclaw/source.mda. Loading this skill confirms that an MDA-emitted SKILL.md installs cleanly via `openclaw skills install <local-dir> --global` and is reported as parsed by `openclaw skills info --json`.
MDA compatibility demonstration skill for OpenCode. Compiled from compat/opencode/source.mda. Loading this skill confirms that an MDA-emitted SKILL.md is discovered and parsed by OpenCode with the envelope subset of fields documented at opencode.ai/docs/skills/ honored.
MDA compatibility demonstration skill for Claude Code. Compiled from compat/claude-code/source.mda. Loading this skill confirms that an MDA-emitted SKILL.md loads in Claude Code with the envelope subset of agentskills.io v1 fields honored.
Minimal MDA source demonstrating relationship-graph footnotes and metadata.mda.* MDA-extended fields. Use as a reference fixture when learning the MDA source format.
Basic compiler conformance fixture.

This skill exists to verify Codex CLI SKILL.md compatibility from an MDA-compiled output.
Three things are true if Codex CLI discovers and loads this skill:
SKILL.md parses under Codex CLI's loader (built on agentskills.io v1).name matches the package directory name (spec ยง06-2.1).name, description, allowed-tools) survives the round-trip from .mda source to compiled output to runtime ingest.Source: compat/codex-cli/source.mda. Compile: mda compile compat/codex-cli/source.mda --target SKILL.md --out-dir compat/codex-cli/build --integrity.
What this does NOT prove:
metadata.mda.* (the OpenAI docs do not document any such behavior, and we do not require it).triggers: arrays) are authored from MDA โ they are not part of agentskills.io v1 and are out of MDA v1.0 scope.
