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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior, so the safety bar is already met. The description adds only the query-characteristic note ('natural language question'), with no mention of result counts, ranking, or how to follow up on hits; an output schema covers return shape.

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?

Three short sentences, front-loaded with the action and resource. Mild redundancy from repeating 'BANKSapi' three times, but nothing is wasted.

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 an output schema present, return values need not be explained, and the single-parameter surface is simple. What is missing is routing context against three sibling documentation tools, which matters for a search-first tool in a docs toolset.

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 0% and the single 'query' parameter has no description, so the description must carry the semantics. It does specify the expected form ('a natural language question about BANKSapi'), which meaningfully constrains how the agent should phrase input rather than passing raw keywords.

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 ('Search the BANKSapi documentation') and enumerates the content types it covers (features, endpoints, integration guides). It does not distinguish itself from the sibling page-fetch or spec tools, which is the main clarity gap.

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?

Implies usage ('use this tool to find information about...') but never states when to prefer it over get-banksapi-docs-page, get-banksapi-openapi-spec, or get-banksapi-overview, nor that search results typically lead to a page fetch. Guidance is inferable but not explicit.

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