MDA Compat Demo (Hermes Agent)

This skill exists to verify Hermes Agent SKILL.md compatibility from an MDA-compiled output.

Three things are true if Hermes discovers and loads this skill:

1. The compiled SKILL.md parses under Hermes Agent's loader.
2. The frontmatter name matches the package directory name (spec §06-2.1).
3. The agentskills.io v1 envelope subset survives the round-trip from .mda source to compiled output to Hermes' skill registry; the reserved metadata.hermes.* namespace passes through verbatim for Hermes' own consumption.

Source: compat/hermes/source.mda. Compile: mda compile compat/hermes/source.mda --target SKILL.md --out-dir compat/hermes/build --integrity.

What this does NOT prove:

• That Hermes parses MDA-extended frontmatter under metadata.mda.* (we do not require it).
• That signatures or integrity digests are verified at load time (no current runtime does that).
• That MDA v1.0 can author Hermes-specific top-level fields (version, author) that some existing Hermes skills carry at top level rather than under metadata.mda.*. Those are out of MDA v1.0 scope under §06-3.4, symmetric with the Claude Code runtime-fields gap.
