Complexity Routing
Tier Classification
Assess every incoming request against these signals:
INSTANT (handle directly)
- Single factual question
- Clarification of existing decision
- Status check or summary request
- No code changes needed
STANDARD (plan → implement → review)
- Single-file or few-file change
- Well-understood pattern
- Clear requirements, no ambiguity
- No security or architectural implications
DEEP (research → plan → implement → review → security)
- Multi-file or multi-module change
- Requires investigation or research first
- Security-sensitive components involved
- New integration or API surface
- Performance-critical path
ULTRADEEP (research → plan → architect → implement → trilateral review)
- Architectural change or new system design
- Cross-cutting concerns (auth, data model, API contract)
- Compliance or regulatory implications
- Irreversible changes (data migration, public API)
- Multiple team/role involvement needed
