# Cost-Tier Routing
The main context runs on opus. Every Read, Grep, Glob, and Edit invoked at this tier bills at opus rates. Most operations don't need opus reasoning — they need a model that can run a command and report a result. This skill is the dispatch gate that stops opus from doing work haiku or sonnet would complete just as correctly for a fraction of the cost.
## The three tiers
| Tier | Model | Owns | Example requests |
| ------------- | ------ | ------------------------------------------ | ------------------------------------------------------------------------------------------------------ |
| **scout** | haiku | Read-only lookup, search, location | "Where is `Foo` defined?", "List files matching `*.test.ts`", "Count LOC in `src/`", "Read X and report Y" |
| **coder** | sonnet | Bounded code changes at known locations | "Add a test for `parseDate`", "Refactor `auth.ts` to use the new client", "Rename `A` → `B` repo-wide" |
| **architect** | opus | Ambiguous spec, tradeoff analysis, design | "Should we use Redux or Zustand?", "Draft an ADR for the auth rewrite", "Why is this architecture failing?" |
## The dispatch decision (run this first, every turn)
Before reaching for any tool, run this classifier against the incoming request:
1. **Is the work entirely read / search / location?** → **scout**. Dispat
