## Current state
`Skill` NodeKind has one shape: directory-of-markdown with `SKILL.md` entrypoint. Anthropic now ships TWO distinct concepts both called "Skill":
- **Anthropic Skills (API)** — model-side feature accessible via Messages API, configured server-side, not filesystem-based. Used by claude.ai.
- **Claude Code Skills** — filesystem-based `SKILL.md` directories, invoked via slash command, can ship in plugins.
Both have `disable-model-invocation` frontmatter, but their distribution and lifecycle differ. The skill node example file `python-django-debug.yaml` references "Anthropic Skills" in its comment but the body is clearly a Claude Code skill.
## Desired state
- Split into `Skill.kind: enum<anthropic-api-skill,claude-code-skill,portable-skill>`.
- Add `Skill.invocationMode: enum<model-invoked,user-invoked,both>`.
- Add `Skill.disableModelInvocation: bool` (matches frontmatter).
- Add a `Term` `term:skill` with `synonym_of` records distinguishing the two senses, `inContext=anthropic-api` vs `inContext=claude-code`.
## Evidence
- https://docs.anthropic.com/en/docs/agents-and-tools/skills (API-level)
- https://code.claude.com/docs/en/skills (filesystem-level)
- C:/work/v6/graph/schema/examples/extensions/skills/python-django-debug.yaml (mislabeled comment)
## Propagation status
- Level 1: open
- Level 2: not-started — terminology.md needs new synonym record
## Propagation chain
- Level 1: split kind enum + 2 attribute additions.
- Level 2: 02-node-kinds/extensions-plugins.md disambiguation block.
## Notes
Without disambiguation, downstream derivations will conflate two different distribution channels.
