# Agent Swarm Wave Pattern for Rust Implementation
|
|
|
|
Used TeamCreate + Agent worktrees for parallel Rust implementation across 3 waves based on dependency graph.
|
|
|
|
## What Worked
|
|
|
|
- **Wave parallelism** works well when tasks map to separate files (`types.rs`, `client.rs`, `importer.rs`, `sync.rs`) — no merge conflicts, each agent owns its file
|
|
- **Full task descriptions** with column mappings and reference file paths let coders work autonomously with zero clarification needed
|
|
- **All 7 coders produced compiling code on first try** — the thorough task specs paid off
|
|
|
|
## Problems Encountered
|
|
|
|
- **Pane limit hit**: Got "no space for new pane" error when 6 idle agents from earlier waves were still alive. Shut down idle agents promptly between waves to avoid this.
|
|
|
|
## Code Review Caught Real Bugs
|
|
|
|
1. **Missing `#[serde(default)]` on 8 TeamData fields** — would cause runtime deserialization panics when API returns objects without those optional fields
|
|
2. **Dead `ApiError::Parse` variant** — `response.json()` returns `reqwest::Error` not `serde_json::Error`, making the Parse variant unreachable. Fix: use `response.text()` + `serde_json::from_str()`
|
|
3. **`import_all_cards` hard-failing** on first missing CSV — changed to resilient independent tries for each CSV
|
|
|
|
## Recommendation
|
|
|
|
Always run a code review agent after implementation waves, especially for error handling and serde derives. The review ROI was high — caught 3 bugs that would have been runtime failures.
