description	End-to-end spec implementation with agent swarms. Analyzes a design spec, identifies gaps, implements with TDD, then runs adversarial review-fix loops until clean.

Spec to Implementation

Automated spec-driven implementation pipeline. Takes a design doc, analyzes gaps, builds with TDD, then adversarial-reviews until no bugs remain. Never merges — produces clean worktrees.

Pipeline

Phase 1: Gap Analysis        →  5-10 sub-agents compare spec vs codebase
Phase 2: TDD                 →  Write failing tests for all gaps
Phase 3: Implementation      →  Build code in worktrees to pass tests
Phase 4: Adversarial Review  →  10-15 reviewers per worktree, fix loop
Phase 5: Prevention          →  Surface ESLint rules + test strategies

No merge phase. This skill produces clean worktrees. Merging is human-initiated.

Loop Behavior

Designed for multi-pass /loop usage. Each invocation is idempotent:

1. Check current state, identify remaining gaps/bugs
2. Fix them, re-review
3. When zero criticals remain → report CLEAN → stop the loop
4. Maximum runtime: 1-1.5 hours (hard cap)

Multi-Pass Trust Model

Don't trust the first pass:

Pass 1: Gap analysis + TDD + implement
Pass 2: Adversarial review → find bugs
Pass 3: Fix bugs → re-review → find more bugs
Pass 4: Fix remaining → re-review → zero criticals → STOP
