agency_search

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

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds behavioral details like output format (matching agents with file paths and spawn template) and the spawning workflow. It does not contradict annotations and provides useful context beyond them.

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 well-structured with <usecase> and <instructions> tags, front-loading the main purpose. Each sentence adds value, though the instructions are detailed. It is concise for the complexity involved.

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?

Despite lacking an output schema, the description comprehensively explains the output (matching agents with file paths and spawn template) and provides full workflow instructions. Given the tool's complexity and the annotations covering safety, the description is complete enough for an AI agent.

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?

Schema coverage is 100% with both parameters described. The description adds example values for query (e.g., 'game mechanics') and division (e.g., 'engineering'), and clarifies that query should be a task description, enhancing the schema's meaning.

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 'Find and launch a specialized agent for any task' and the usecase elaborates on searching agent templates by keyword, returning file paths and spawn templates. It distinguishes from siblings (agency_browse, agency_status, agency_update) by focusing on search and spawning, not browsing, status, or updates.

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 explicitly states 'Call this before spawning any agency subagent' and provides step-by-step instructions on how to use it: pass task description, pick best match, spawn using the template, and return response directly. This gives clear when-to-use and how-to-use guidance.

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