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

Annotations already cover the safety profile (readOnly=false, destructive=false, openWorld=false), so the bar is lower, but the description adds nothing beyond the route: it does not say whether this is a full replace or partial patch, whether unknown fields are dropped, what permissions are required, or what the response contains. For a mutation tool that is a real gap.

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 with the operation front-loaded, so nothing is wasted, but the second sentence merely restates the HTTP verb/path and the whole entry is under-specified rather than genuinely concise.

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 nested-payload mutation tool with no output schema and only safety annotations, the description leaves the agent guessing about update semantics, required fields, and side effects. The rich body schema partially compensates, but the definition as a whole is thin for this complexity.

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?

Top-level schema description coverage is 0% — neither id nor body is documented, and the description does not compensate by explaining that id identifies the bot instance and body carries the update payload. The nested body properties are well described in the schema, but that credit belongs to the schema, not the description.

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 ("Update prediction signal bot") plus the exact HTTP route, which maps unambiguously to the prediction-bot update family and distinguishes it from post_bot_signal_prediction and delete_bot_signal_prediction_id. It does not, however, contrast itself with the very similar sibling put_bot_signal_prediction_id_status.

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 guidance on when to use this over put_bot_signal_prediction_id_status, the folder variant, or post_bot_signal_prediction_duplicate. The agent must infer intent purely from the name and route.

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