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

The description adds valuable behavioral context beyond annotations: it explains that agents run independently and results are returned together. However, annotations already cover read/write status (readOnlyHint=false, destructiveHint=false, openWorldHint=true), so the bar is lower. The description doesn't mention potential side effects like resource consumption, error handling, or how results are structured.

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

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

The description is perfectly concise with three sentences that each earn their place: first states the core functionality, second explains behavioral characteristics, third provides usage examples. It's front-loaded with the most important information and wastes no words.

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

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

Given the tool's complexity (parallel agent spawning) and rich schema coverage, the description provides good context about the tool's behavior and use cases. However, without an output schema, it doesn't explain what the return structure looks like (e.g., how results from multiple agents are organized). The annotations provide safety information, but the description could better address potential failure modes.

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

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

With 100% schema description coverage, the schema already documents all parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema. The baseline score of 3 reflects adequate but not enhanced parameter documentation given the comprehensive schema.

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

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

The description clearly states the tool's purpose with specific verbs ('spawn multiple AI agents in parallel') and distinguishes it from sibling tools like 'spawn_agent' (singular) and 'list_agents'/'kill_agent'/'get_status' (different operations). It explicitly mentions parallel execution and independent agent operation.

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

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

The description provides clear usage context with examples ('great for getting multiple opinions, parallel code reviews, or distributing subtasks'), which helps understand when to use this tool. However, it doesn't explicitly state when NOT to use it or directly compare it to the 'spawn_agent' sibling tool for single-agent scenarios.

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