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

The description goes well beyond the sparse annotations by disclosing that requests are logged, Agent Beacon commits to no fulfillment, no payment is accepted, and PII-like strings are scrubbed before storage. It also discloses the response shape (request_id and return_token), giving the agent a full behavioral picture.

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 concise, front-loaded with the core purpose, and every sentence adds value: no-fulfillment caveat, no payment, privacy warning, data scrubbing, and return values. There is no filler or repetition.

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?

The description covers the essential non-schema behaviors needed to invoke correctly: logging, no fulfillment commitment, payment prohibition, privacy guidance, PII removal, and return token usage. For a high-parameter tool without an output schema, this is sufficient context for an 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%, so the structured schema already documents all 17 parameters including required fields and enums. The description adds no parameter-level detail, which is acceptable given complete schema coverage; baseline 3 applies.

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 specific action: describing a capability the agent needed but couldn't find, and explains Agent Beacon logs the request without fulfilling it. It is readily distinguished from the siblings check_request_status and describe_beacon.

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 gives clear context for when to use the tool (when a needed capability is missing) and states exclusions such as no payment accepted and no confidential information. It does not explicitly compare to sibling tools, but mentions the return_token for checking status later, implying the follow-up path.

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