Tdd Pattern

Use this skill whenever you are running as the `red` or `green` agent on an agile-team-v2 task. Covers the discipline-based spec isolation between red and green (no private TASK*.md files exist; the only handoff is committed code/tests), the in-scope vs out-of-scope rules of the red/green pattern (applies to standard and architectural complexity features only — mechanical maintenance is a mono-agent task), the mono-assistant safeguard when one Claude instance must wear both hats sequentially (commit red first, fresh session before reading green-side material — `check.sh` audits this at sprint review), and the marker-based task lookup procedure (grep for `TODO(impl-<slug>, ac-<NNN>)` to locate the scaffolded body and its sibling test file). Loaded only by `red` and `green`. Other agents (architect, PM, sprint-planner, e2e-tester, reviewer, bug-detective) operate outside the live red/green isolation flow and do not need these rules.
