Beforegeneric AI agent
Routing tasks to different models is definitely a cost-optimization strategy worth exploring. The idea makes sense—simple tasks don't need Opus-level intelligence, so you could use a cheaper model for those and save money. But there are trade-offs to consider. You'd need to define what counts as simple versus complex, and you'd have to accept that some tasks might get worse results from a cheaper model. The routing logic could get complicated if you want to be fine-grained about it. There are a few different approaches you could take depending on your workflow. Do you use Claude Code's hooks system? That might be the best place to implement this, but I'd need to understand your typical task patterns first.
Afterwith Claude Router
ROUTING RULES CONFIGURED: Claude Code task routing

CURRENT SPEND: 280 USD/month (Opus-only)
PROJECTED SPEND: 140 USD/month (50% reduction)
SAVINGS: 140 USD/month, 1680 USD/year

ROUTING LOGIC:

FILE EDITS: Route to Haiku
→ Tasks: Single-file changes, formatting fixes, small bug patches
→ Latency gain: 3x faster
→ Token savings: 70% vs Opus
→ Success rate: 96% (edge cases escalate automatically)

TEST WRITING: Route to Sonnet
→ Tasks: Unit tests, integration test scaffolds, fixture setup
→ Latency: 2x faster than Opus
→ Token savings: 45% vs Opus
→ Success rate: 92% (complex test logic stays on Opus)

ARCHITECTURE DECISIONS: Keep on Opus
→ Tasks: Multi-file refactoring, system design, trade-off analysis
→ Decision: These require reasoning depth only Opus provides
→ Cost per task: Higher, but prevents costly mistakes

RECURSIVE ESCALATION:
If Haiku fails twice on same task → escalate to Sonnet
If Sonnet fails twice → escalate to Opus
Direct to Opus for first attempt if task tags mention complexity

CONFIG FILE: ~/.claude/routing-rules.json
IMPLEMENTATION: Via Claude Code hooks (settings.json)
MONITORING: Dashboard tracking success rate per model + spend trends

ESTIMATED SETUP TIME: 1 hour
ROLLOUT PLAN: Opt-in for 2 weeks, measure, then default on

About this skill

Claude Router

Claude Code Router lets you configure rules so simple tasks route to cheaper or faster models while complex tasks go to Opus, reducing overall spend. Referenced as one of the top GitHub-trending Claude Code tools.

What you get

  • Configurable model-routing rules for Claude Code sessions.

Customize your output

  • Define your own routing rules by task type or complexity.

Example output

Routine file edits routed to a cheaper model while architecture decisions route to Opus.

Best for

Heavy Claude Code users trying to reduce token spend.
