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

Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description adds only the raw HTTP path, which is endpoint trivia rather than behavioral context (no auth requirements, error behavior, or scope). It contributes essentially nothing beyond the annotations.

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 purpose front-loaded and no padding. The endpoint path sentence is low-value but does not bloat the definition.

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 simple single-parameter read tool whose annotations already cover the safety profile, this is close to sufficient. The remaining gap is disambiguation from the large family of sibling webhook getters, which the description never addresses.

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 carries the burden for the single 'id' parameter. 'by ID' does signal that the parameter is an identifier of a bot webhook, which is marginal added meaning, but it gives no format, source, or constraints.

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 ('Get') and resource ('bot webhook') qualified by 'by ID', which is clearer than the bare tool name. It does not, however, differentiate itself from the many sibling webhook getters (e.g. get_webhook_bot_id_shares, get_webhook_bot_bot_signal_id_cex) that also operate on a webhook bot.

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 use this versus get_webhook_bot (the list variant) or the sub-resource getters. The agent must infer the single-record-vs-collection distinction from the 'by ID' phrasing alone.

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