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

Annotations already declare non-read-only, non-destructive, non-idempotent, closed-world, so the safety profile is partly covered. The description adds genuinely non-redundant context: it excludes profile content and personal details unless the user asks, states the user's words travel verbatim, and describes the reply shape (receipt or failure sentence) plus a cost hint.

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?

Front-loaded Purpose/When/Cost structure with the core action first and no filler sentences. Slightly dense long sentences, but every clause carries information (scope, privacy, verbatim text, response shape).

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 3-parameter tool with a nested `about` object, full schema coverage, annotations and an output schema, the description covers purpose, trigger, privacy behavior and the response contract. Little is missing; only repeated-call/idempotency expectations are left implicit.

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 coverage is 100% and each field (kind enum, text length, about nesting) is already documented in the schema. The description reiterates rather than extends — 'with the posting or monitor it concerns when known' mirrors the schema's 'when known' phrasing — so baseline 3 is appropriate.

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 ('Send the user's feedback on searchnapply to its team') and enumerates the cases it covers (wrong answer, fault, suggestion) with the optional subject. No sibling tool overlaps with feedback submission, so the agent can route it unambiguously.

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?

The 'When' line gives an explicit trigger: a problem with searchnapply or its results arose and the user agreed to report it. No alternatives need to be named because no sibling does anything similar, but the guidance is context-only rather than a full when/when-not rule set.

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