CrewScore

Overview

CrewScore is a freemium tool designed to help developers and teams ensure the quality of AI agent prompts. It performs coverage checks to identify gaps in prompt instructions, helping to improve reliability and performance of AI agents. By analyzing prompts against expected behaviors, CrewScore aims to reduce errors and enhance the effectiveness of AI-driven workflows. The tool is particularly useful for teams building complex AI agents that require precise and comprehensive instructions.

Who Is This Tool Best For?

CrewScore: the questions that come up

What is CrewScore?

A tool that analyses agent prompts against expected behaviour and reports the gaps: instructions that are missing, ambiguous or in conflict.

Who is it for?

Developers and teams shipping agents where a missed instruction shows up as an unreliable result rather than an obvious error.

Is CrewScore free?

There is a free tier for checking prompts with limits, and paid plans raise the number and size of the checks. Cost tracks how much you test.

Why check a prompt at all?

Because most agent failures are unstated requirements. Writing the expectations down and testing the prompt against them is what makes behaviour repeatable.

Use cases

Finding missing instructions

Comparing a prompt against expected behaviour surfaces the requirement nobody wrote down.

Catching contradictions

Instructions that conflict produce inconsistent runs, and they are easy to miss when reading your own prompt.

Reviewing before a release

A coverage check as a step before deploying is cheaper than finding the gap in production.

Alternatives

  • A test suite for your agents — More work and far more precise, once you know what to assert.
  • Manual prompt review — Free, and it reliably misses the instruction you assumed.
  • An evaluation platform — Measures output quality across runs, which complements a coverage check.

Every one of them is catalogued in our AI tools directory.

Pricing

CrewScore can be used at no cost within limits, assessed at 4.3. A free tier for checking prompts with limits, and paid plans that raise the number and size of checks. Because prompts are cheap to iterate, the plan should follow how often you test rather than how many agents you run. Details are on the vendor site. Live terms sit with the CrewScore site.

Before you sign up

Write the expected behaviour down

A coverage check needs something to check against. The list of expectations is the real artefact.

Keep the prompts in version control

Coverage results only mean something next to the version of the prompt they describe.
