Three journey E2E tests (ideation, ship, debug) were failing because
Claude answered directly instead of invoking the Skill tool. Root cause:
skill descriptions in system-reminder are too weak to override Claude's
default behavior for tasks it can handle natively.
Fix has two parts:
1. CLAUDE.md routing rules in test workdir — Claude weighs project-level
instructions higher than skill description metadata
2. "Proactively invoke" (not "suggest") in office-hours, investigate,
ship descriptions — reinforces the routing signal
10/10 journey tests now pass (was 7/10).
