Claude d8d9f489da rename CONTEXT.md/CONTEXT-MAP.md convention to GLOSSARY.md/GLOSSARY-MAP.md
The prior commit renamed only this repo's own root glossary. This
commit does the thing actually asked for: repoint every skill and doc
that reads/writes the domain-doc convention in consumer repos —
domain-modeling, grill-with-docs, improve-codebase-architecture,
setup-matt-pocock-skills, triage, tdd, diagnosing-bugs, ask-matt,
codebase-design, wait-what — plus their docs pages, .agents/ notes,
and the top-level README. CONTEXT-FORMAT.md is renamed to
GLOSSARY-FORMAT.md alongside it.

Left untouched on purpose: CHANGELOG.md and the one still-unreleased
CONTEXT.md-era changeset, both historical records of what shipped
under the old name; and the README's pinned course-video-manager
link, which points at a real file that is still literally named
CONTEXT.md at that commit in another repo.

Model-invoked vs user-invoked

Every SKILL.md in this repo is a skill. The one axis that splits them is invocation — who can reach it:

  • User-invoked — reachable only by the human typing its name. Set disable-model-invocation: true in the frontmatter (Claude Code) and policy.allow_implicit_invocation: false in agents/openai.yaml (Codex). The description is human-facing: a one-line summary read by a person browsing slash-commands. Strip trigger lists ("Use when the user says…").
  • Model-invoked — reachable by model or user. The default: omit disable-model-invocation and the policy block from agents/openai.yaml. The description is model-facing and keeps rich trigger phrasing ("Use when the user wants…, mentions…, asks for…") so auto-invocation fires. The test for whether a skill should stay model-invoked: could the model usefully reach for this autonomously? (Reuse is the reason to extract a skill, not the test.)

Each harness excludes a user-invoked skill from the model's reach in its own way, so nothing but the human can fire it — no other skill can. A user-invoked skill may invoke model-invoked skills, but it can never reach another user-invoked skill.

Every skill also carries an agents/openai.yaml beside its SKILL.md. It holds Codex UI metadata — interface.display_name and interface.short_description for the skill picker — and, for user-invoked skills, the policy.allow_implicit_invocation: false that pairs with disable-model-invocation. Keep the two in sync: a skill is user-invoked in both harnesses or neither.

Bucket README.mds and the top-level README.md group entries into User-invoked and Model-invoked.

Dependencies between them

Dependencies are expressed as /skill-style prose invocation ("Run the /grilling skill"), not deep ../other-skill/FILE.md cross-references. Shared reference docs live inside the skill that owns them; other skills reach that material by invoking the skill, not by linking across folders.

Passive vs active domain work

Merely reading GLOSSARY.md for vocabulary is a one-line prose pointer, not the domain-modeling skill. Only the active build/sharpen discipline (challenge terms, edge-case scenarios, write ADRs, update GLOSSARY.md inline) is domain-modeling.
