Schema Author
Use this skill when a task changes the active Brain schema pack in Brain/_brain.yaml or reviews content against that schema.
Workflow
- Inspect the active schema pack with
schema_inspect (view="active_pack") or o2b brain schema --json.
- Check current usage and findings with
schema_inspect views stats, lint, and orphans.
- Explain candidate tokens with
schema_inspect (view="explain_type") before renaming or deleting them.
- Apply schema changes only through
schema_apply_mutations or o2b brain schema apply --mutation ... so writes are locked, atomic, and audited.
- Re-run lint/stats after mutation and report changed tokens plus any remaining findings.
Mutation Notes
Supported operations are add_type, remove_type, update_type, add_alias, remove_alias, add_prefix, remove_prefix, add_link_type, remove_link_type, set_extractable, and set_expert_routing.
Schema tokens must be lowercase normalized tokens accepted by Open Second Brain schema validation. Prefer small, durable tokens over project-specific phrasing unless the schema pack is explicitly project-scoped.
