Select the narrowest useful Codex agent, skill, MCP, and config route for non-trivial work. Use when delegation, context placement, specialist ownership, duplicate skill aliases, or routing visibility materially affects execution; avoid for trivial single-surface work.
Plan token and context usage before broad Codex work. Use for repo-wide, research-heavy, multi-agent, documentation-heavy, or long-running tasks that need a context budget, source priority map, compaction handoff, and verification gates.
Maintain, audit, and improve Codex Chef setup repositories. Use for README/docs/template/catalog/installer/validation updates, release-readiness work, and safe Codex starter maintenance without weakening security, leaking local state, or changing external systems.
Create editable offline diagrams from an English description or Mermaid source. Use when Codex should emit a triplet: Mermaid source, an editable .excalidraw file for excalidraw.com, and rendered SVG/PNG assets with zero network access.
