Summary

Remove the documentation and agent configuration introduced by the Matt Pocock skills workflow:

• Drop GLOSSARY.md and all docs/agents/*.md files.
• Remove the ## Agent skills section from AGENTS.md while retaining the project's upstream-first rules.
• Keep the project's functional tests and GitHub Actions workflows unchanged.

Evidence

• rg finds no remaining references to docs/agents, GLOSSARY.md, grill-with-docs, or domain-modeling.
• make test passes: 10 CLI checks and 3 binary checks.

Merge Danger

Door: two-way

Documentation-only cleanup. Reverting restores the removed configuration files.
