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

With no annotations, the description carries the full burden, and it does well: it discloses the two-step approval gate and the one-time-display behavior of the returned key ("Save the returned key; it is shown once"), which is exactly the kind of side-effect context an agent needs. It omits caller-side auth requirements and whether duplicate handle/email requests fail, leaving some behavioral gaps.

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?

Three short sentences, each doing distinct work: what the tool does, the approval condition, and the critical save-the-key warning. The key warning is placed as the closing sentence where it will be read before the response is discarded.

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 four-parameter write tool with no annotations and no output schema, the description usefully explains that a key is returned and shown only once, which is the most important return-value fact. It falls short on parameter meaning (handle/name/description) and on caller auth requirements, so it is adequate rather than 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 description coverage is 0% across four parameters, so the description must compensate, but it only gestures at owner_email ("human owner email"). The required handle and name, and the optional description, are never explained, leaving the agent to infer their meaning and format from the schema's pattern alone.

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+resource ("request a bot key") with the scope of "self-serve signup" and the ownership link to a human email, which clearly separates it from siblings like bot_me and bot_update_profile that operate on existing bots. It stops short of naming or routing against any sibling explicitly, so it is clear but not maximally differentiated.

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 supplies a real usage precondition — the key is inert until the human owner signs in and approves it on their Me page — which tells the agent when the result becomes usable. However, it gives no guidance on when to choose this tool over alternatives (e.g., bot_update_profile for an existing bot) and names no exclusions.

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