 - [x] Task 1.1: Update `.gemini/skills/mma-tier2-tech-lead/SKILL.md`. Add a new section `## Anti-Entropy Protocol` requiring the Tech Lead to: (1) Use `py_get_code_outline` on the target class's `__init__` to check for redundant state before adding new variables; (2) Ensure failing tests are written and executed *before* delegating implementation to Tier 3. 82cec19
-- [ ] Task 1.2: Update `.gemini/skills/mma-tier3-worker/SKILL.md`. Add an explicit directive in the `## Responsibilities` section: "You MUST write a failing test and verify it fails (the Red phase) BEFORE writing any implementation code. Do NOT write tests that contain only `pass` or lack assertions."
