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

With no annotations the description carries the full burden. It usefully discloses that the tool only returns a request and does not execute it or move payment, and notes the date format. However, it omits auth requirements for actually running the request, response/request format details, and other behavioral traits.

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?

Compact two-part description with purpose front-loaded and the non-execution caveat plus date note appended. Every clause earns its place, though it stays in a single run-on sentence rather than being clearly segmented.

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 4-parameter request-generating tool with no annotations and no output schema, the description covers the core purpose and the key non-mutation caveat. It falls short on documenting room and bucket parameters, which an agent would need to call it correctly.

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 description coverage is 0%, so the description must supply parameter meaning. It only explains since/until as ISO dates and vaguely implies bucket values ('per hour or day'); the 'room' parameter and explicit bucket options are never addressed, leaving most parameters undocumented.

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?

States a specific verb and resource: it 'Returns the exact HTTP request needed to get new signed identities per hour or day.' The 'identity_rate' scope is distinctive, but it does not explicitly differentiate itself from sibling '_request' tools like tclk_audit_request or did_bot_check_request.

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?

Conveys usage only implicitly – it builds a request for identity rates – and there is no explicit when-to-use or named alternative. The one boundary it does give ('this tool does NOT run it or move any payment itself') clarifies a usage limit but not selection between siblings.

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