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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=false, so the safety profile is covered. The description adds meaningful context beyond that: the deletion cascades to webhook headers and the send log. It stops short of 5 because it says nothing about irreversibility, permissions, or effect on related log entries.

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?

A single front-loaded sentence with no filler; the verb and the cascade consequence are packed efficiently. There is little room to improve, though it is minimal rather than exemplary in structure.

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 two-parameter destructive tool with full schema coverage, complete annotations, and no output schema, the description covers the important unknown: what else is destroyed. Missing only permanence/permission notes, which keeps it from a 5.

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 100%, with both quiz_id and webhook_id documented in the schema (including a pointer to get_quiz_webhooks). The description adds no parameter-level detail, so the baseline of 3 applies.

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?

The description states a specific verb and resource ('Удаляет вебхук опроса') and additionally notes that headers and the send log are removed, which sharpens the scope. It does not explicitly distinguish itself from siblings like toggle_quiz_webhook or update_quiz_webhook, so it falls short of a 5.

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 delete versus simply disabling via toggle_quiz_webhook, nor any prerequisite or warning about permanence. The intended usage is only implied by the verb 'удаляет'.

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