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

With no annotations, the description carries the full burden: it implies a state mutation but says nothing about whether already-queued events are dropped, whether pausing an inactive webhook errors, or whether the operation is idempotent, and the '@return: a json object' gives no meaningful disclosure of the response.

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 opening purpose sentence appears verbatim twice, which is pure waste and pushes the actual substance down. The @param and @return lines are an unedited docstring block that was never front-loaded or trimmed for agent consumption.

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?

With no output schema and no annotations, the description would need to cover return shape and failure modes, which it largely does not ('a json object'). It does adequately cover all three required parameters, so it is usable but not complete for a mutation tool with a three-parameter contract.

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 is the only source of parameter meaning — and it does add value by naming each parameter and its source (api_key for the application, token and wallet_fk from /access/login). It stops short of format or type details, but this is meaningfully better than a bare schema.

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: 'Pauses the webhook on this wallet from receiving events'. An agent can immediately tell this is the pause counterpart to webhook_resume, though the description never names that sibling explicitly.

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?

There is no guidance on when to pause versus using webhook_resume, webhook_set, or webhook_view, and no prerequisites or preconditions are stated. The agent must infer usage entirely from the name and the one-line purpose.

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