Scores agent actions by expected gain, cost, uncertainty, and redundancy. Use when deciding whether to dispatch an agent or invoke a tool.

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

# Utility Skill

## Overview

A decision framework for agent orchestration based on Liu et al.,
"Utility-Guided Agent Orchestration for Efficient LLM Tool Use"
(arXiv:2603.19896).
Each candidate action is scored by subtracting weighted costs from
expected gain, producing a single utility value that guides action
selection.
The framework prevents over-calling tools and premature stopping by
making both errors costly.
Utility range is [-2.3, 1.0].

## When To Use

- Deciding whether to dispatch another agent or tool call
- Gating expensive tool calls (search, code execution, delegation)
- Selecting the right model tier for a sub-task
- Continuation decisions after receiving partial results
- Verification gating before writing or committing output

## When NOT to Use

- Single-step operations with one obvious action
- Trivial tasks where cost of scoring exceeds benefit
- Already-committed actions that cannot be undone

## Action Space

`A = {respond, retrieve, tool_call, verify, delegate, stop}`

| Action | Description |
|-----------|------------------------------------------------------|
| respond | Emit a final answer from current context |

How to install

The exact contents, by fingerprint
mdr add athola/claude-night-market/utility@sha256:bb61ab7794da617d

The line at the top of this page pins the label git:20261028.7246d08, 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.
