CrewAI MCP Orchestrator

crewai_test_crew

Test multi-agent crew performance by running specified iterations and evaluating outputs with an LLM model.

Instructions

Test the crew's performance and evaluate outputs.

Runs crewai test -n {iterations} -m {model}. This helps in assessing the quality of the crew's execution.

Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description only states it runs a CLI command; does not disclose side effects (e.g., whether it modifies anything), auth requirements, or safe-to-invoke status.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences, front-loaded with purpose, no unnecessary words. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 3 parameters and no annotations, description is too sparse. Does not explain return values (though output schema exists) or mention any dependencies like project existence.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% so baseline is 3. Description adds no extra meaning beyond schema; merely restates command syntax without clarifying parameter usage or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description uses specific verb 'Test' and resource 'crew performance and outputs', clearly distinguishing it from siblings like crewai_kickoff (run) and crewai_train_crew (train).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs. alternatives like crewai_kickoff or crewai_train_crew. Does not specify prerequisites or context for testing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
