Use when routing tasks to the cheapest fitting model tier.
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
# Model Routing Cost Optimizer Route every agent task to the cheapest model that can still do it well. This skill establishes a three-tier model hierarchy (cheap / mid / premium), a task classifier that buckets work into ROUTINE / MODERATE / COMPLEX, and the decision rules that turn a description into a model pick. It does not enforce any one provider — the tier prices live in `references/model-pricing.md` so the body stays provider- neutral — and it does not cover local quantized inference. The core belief is blunt: most agent work is routine, and routing routine work to a premium model is pure waste. Down-tier by default; escalate on evidence, never on habit. ## When to Use Use this skill when you want to: - Choose which model should handle a task, a sub-agent, or a cron job. - Decide whether the current model is overkill for what you are about to run. - Spawn sub-agents at a cost that matches the work. - Keep heartbeat, monitoring, and scheduled-report traffic off premium models. - Explain to a teammate why one model is running a task instead of another. - Classify a batch of tasks into ROUTINE / MODERATE / COMPLEX for tiering. …

How to install
mdr add jpeetz/agent-skills/model-routing-cost-optimizer@sha256:bbc1c69d97cc0c90The line at the top of this page pins the label v1.0.0, 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.
