- All agent profiles used the misspelled 'user-invokable' property, which
Copilot CLI silently ignores, so internal-only agents (scout, splitter,
builder, verifier, integrator, scribe) were never actually hidden from
the /agent picker. Renamed to the documented 'user-invocable'.
- conductor/architect instructions said only 'Run lh run event' with no
flags, forcing the model to trial-and-error discover --type/--status/
etc. Documented the exact lh run start/event/end CLI syntax inline.
