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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds that results are passages with titles and source URLs, but that return-format detail is largely duplicated by the existing output schema.

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 tight sentences, purpose front-loaded before the return description, with no filler. Slight demerit because the return-format sentence restates what the output schema already conveys.

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 read-only search with a full output schema and clear annotations, the description supplies enough to invoke correctly. The only missing piece is the explicit boundary with get_help_article, which would make selection unambiguous.

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% — both query and limit are documented in the schema, including the 1–8 cap. The description's phrase 'for instructions, feature explanations, and troubleshooting' hints at query phrasing but adds no syntax, format, or default-value detail beyond what the schema already gives.

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?

Clear verb+resource: 'Search LiftTrack's Help Center articles and FAQs', with the covered content types spelled out (instructions, feature explanations, troubleshooting). It does not, however, distinguish itself from the sibling get_help_article, so an agent must infer the search-vs-fetch split on its own.

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?

Usage is only implied: the mention of instructions/features/troubleshooting suggests when the tool is useful, but there is no explicit when-to-use statement and no routing to the obvious alternative get_help_article for retrieving a full article by ID.

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