Devil Starswarm
Multi-perspective review via parallel Agents. Unleashes its true power on large-scale changes where cost is acceptable.

Enhances: 2026-03-23-devil-checklist-driven-review Effect
Runs Devil Chain’s 4 steps across separate Agents in parallel. Roughly 4x faster than serial execution.
| Security Agent | Perf Agent | Logic Agent | Flow Agent |
|---|---|---|---|
| ↓ | ↓ | ↓ | ↓ |
→ Merge → Concern List → Fix → Rerun
When to Use
- Changes span 50+ files or cross multiple services
- Agent cost (~0.18 × 4 turns) is acceptable
- Speed is critical (e.g., pre-release blocker)
How It Works
1. Launch 4 Agents in Parallel
Spin up AI agents in parallel, each with a specialized prompt for Security / Performance / Logic / Flow
2. Merge Results
Combine concern lists from all Agents. Deduplicate and prioritize.
3. Fix → Rerun
If concerns remain, fix them. Large fix scope → re-Starswarm. Small scope → fall back to Chain.
Combinations
| Card | Synergy |
|---|---|
| Devil Chain | Prerequisite card. Without understanding Chain, you cannot integrate the results |
| Devil Gate | Feed the relevant checklist to each Agent (precision UP) |
Cost
Serial Chain: ≈ 1 turn (you run it yourself)
Parallel Starswarm: ≈ 0.72 (0.18 × 4 Agent turns)
Trade-off: API cost ↔ review speed”…Surround them on all sides, and there’s nowhere left to run.” — Eris
