Adaptive budget-aware model routing. Manages 4-tier system to maximize $200/mo Max plan usage across full weekly cycle. Run when starting sessions, hitting usage warnings, or optimizing sub-agent costs.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## When to Use

- Session start (automatically via hook)
- When Claude flags usage at 75%, 90%, or 95%
- Breaking large tasks into sub-tasks with different complexity levels
- When starting overnight/long-running autonomous sessions
- When you want to check or change the current budget tier

## Adaptive Budget System (Maintainer Directive — April 10, 2026)

The $200/mo Max plan has a weekly rolling limit. Opus burns ~5x faster than Sonnet. Without management, budget exhausts in 3 days.

### 4-Tier System

| Tier | Name       | Model    | Effort | Subagents | Cost vs Opus  |
| ---- | ---------- | -------- | ------ | --------- | ------------- |
| 1    | FULL POWER | opus     | max    | inherit   | 1x (baseline) |
| 2    | BALANCED   | opusplan | high   | sonnet    | ~0.3-0.4x     |
| 3    | CONSERVE   | sonnet   | high   | haiku     | ~0.15x        |
| 4    | EMERGENCY  | sonnet   | medium | haiku     | ~0.1x         |

### Quick Commands

```bash
# Check current tier
scripts/budget-manager.sh status

# Record a usage warning (when Claude flags it)
scripts/budget-manager.sh warn 75
scripts/budget-manager.sh warn 90

# Force full power for a critical session

How to install

The exact contents, by fingerprint

mdr add naman10parikh/agentgrid/model-routing@sha256:31bce41e7142df66

The line at the top of this page pins the label git:20260526.f887f6c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
