# MDA Compat Demo (Codex CLI)

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:

1. The compiled `SKILL.md` parses under Codex CLI's loader (built on agentskills.io v1).
2. The frontmatter `name` matches the package directory name (spec §06-2.1).
3. The agentskills.io v1 envelope subset (`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:

- That Codex CLI parses MDA-extended frontmatter under `metadata.mda.*` (the OpenAI docs do not document any such behavior, and we do not require it).
- That signatures or integrity digests are verified at load time (no current runtime does that).
- That non-standard top-level fields observed in some shipped Codex skills (for example `triggers:` arrays) are authored from MDA — they are not part of agentskills.io v1 and are out of MDA v1.0 scope.
