+# Agent Swarm Workflow for Parallel Rust Implementation
+
+## Context
+Used during SBA Scout Rust rewrite Phase 1 to parallelize implementation across multiple files.
+
+## Workflow Pattern
+
+1. **Create team** — spin up tmux-backed swarm with named agents
+2. **Create tasks with dependencies** — map out which tasks are unblocked vs. blocked
+3. **Fan out unblocked tasks** to `swarm-coder` agents (bypassPermissions mode)
+4. **Send completed work to `swarm-reviewer` agents** for code review
+5. **Fix issues found by reviewers** before proceeding
+6. **Dispatch newly-unblocked tasks** after dependencies complete
+
+## Critical Rule: File Contention
+
+When multiple tasks write to the **same file** (e.g., all query functions going into `queries.rs`), batch them into **one coder agent** to avoid merge conflicts.
+
+Tasks touching **different files** (e.g., `main.rs` vs `queries.rs` vs `schema.rs`) can safely run in parallel.
+
+## Agent Configuration
+- Model: Sonnet (per Cal's preference for sub-agents)
+- Mode: `bypassPermissions` for coder agents
+- Reviewer agents: separate agent instances, no bypass needed
+
+## Outcome
+Phase 1 completed faster than sequential implementation. Reviewer caught a missing `UNIQUE` constraint on `lineups.name` that was fixed before commit — review step proved valuable.
+
+## Applicable Projects
+Any multi-file Rust (or other language) implementation where tasks can be decomposed by file/module ownership.
