# Subagent Review-Tier Calibration for Overnight PR Chains
## Problem
`superpowers:subagent-driven-development` prescribes a strict two-stage review per task: spec compliance reviewer first, then code-quality reviewer. For a single feature or a 3-task plan, that's correct — quality dominates throughput.
For an **overnight chain of 10+ independent PRs** from one plan, blindly following two-stage means 20+ review subagent dispatches with sequential dependencies (next task gates on previous merge). Even when individual subagents take 5 minutes, the chain wall time balloons to 3-4 hours of review alone, and the orchestrator context burns through skill-list reminders.
The fix is **per-PR tier selection**, not blanket two-stage:
- **Tier 1 (two-stage, full)** — for PRs touching data contracts, handler architecture, or shared schemas
- **Tier 2 (combined single-agent)** — for moderate-risk PRs (new template + view + tests, well-scoped)
- **Tier 3 (bash-only verification)** — for low-risk PRs (pure visual restyle, no flow change, all tests green in implementer report)
Calibrate per-PR, not per-chain. Some chains run Tier 1 throughout (high-risk migration); others can use Tier 3 for the bulk and reserve Tier 1 for the 2-3 high-risk PRs.
## Context / Trigger Conditions
Apply this calibration when **all** of these hold:
1. You're orchestrating `superpowers:subagent-driven-development` against a plan with 10+ tasks
2. The user has authorized auto-merge on green review
3. Tasks ar
