update_agent

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

Discloses that setting webhook_url to null disables webhook push, which is a behavioral trait not in schema. However, no annotations are provided, so description carries full burden and omits details like partial vs full update, idempotency, or required permissions.

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?

Two short sentences, front-loaded with intent, zero unnecessary words. Every piece of information earns its place.

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?

For a simple update tool with 5 optional parameters and no output schema, the description covers core functionality and a key behavioral nuance (null disables). Lacks mention of partial update semantics, but context signals confirm no required params, so it's fairly complete.

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% (5 parameters). Description adds value by listing them in prose and explaining the null behavior for webhook_url. This slight enhancement over schema justifies a score above baseline 3.

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?

Clear verb 'update' and resource 'agent configuration'. Lists specific updatable fields (webhook, secret, format, name, email). Distinguishes from sibling create (register_agent) and list (get_my_agents) tools.

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?

No explicit guidance on when or when not to use this tool versus alternatives like register_agent or get_my_agents. No context about prerequisites or intended user.

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