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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds only the raw REST endpoint, which restates the operation without disclosing what gets destroyed, whether it is reversible, or any auth/rate-limit context.

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, front-loaded sentences with no filler. The endpoint string is mildly redundant against the annotations 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?

Acceptable for a simple one-parameter delete tool whose destructive nature is already flagged by annotations and which has no output schema to explain. It still lacks any usage context or id-format guidance, leaving it at minimum viable.

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% for the single required "id" parameter, so the description technically carries the burden. The DELETE path template with {id} implies id is a path identifier for the webhook-data resource, which adds marginal meaning, but nothing about format or where the id originates is stated.

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 ("Delete data webhook"), which cleanly separates it from delete_webhook_bot_id and delete_webhook_data_share_id. It is clear but does not itself articulate the distinction; the differentiation rides on the tool name rather than the description text.

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 when-to-use, prerequisites, or alternative guidance is given. The agent is told what the tool does but not when to prefer it over delete_webhook_bot_id or delete_webhook_data_share_id.

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