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

Annotations only say readOnlyHint=true, so the description carries the rest: it discloses that content is returned verbatim, that the filter narrows to matching question/answer pairs, and importantly that an empty result is reported honestly rather than fabricated. It does not cover result shape or size bounds, but for a static read that's a minor gap.

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-loads what is returned, then filtering, then the sibling boundaries, then the no-match behavior. Every clause carries distinct information; the topic enumeration is load-bearing because it tells the agent which questions this FAQ actually answers.

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?

Single optional parameter, readOnly annotation, no output schema — for that complexity the description covers source, content scope, filtering, sibling boundaries, and empty-result behavior. Nothing an agent needs to call it correctly is missing.

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 already documents the case-insensitive match against questions and answers. The description's "filter with a search term to return only matching pairs" restates that at the pair level but adds no syntax, partial-match, or multi-term behavior beyond the schema, so the 3 baseline 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?

Specific verb (returns) plus specific resource (the general Intune Ready FAQ from the homepage) with enumerated topic coverage. It explicitly distinguishes itself from the sibling FAQ tools by naming them, so an agent can select it without opening the schema.

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?

States both the include case (general/homepage FAQ topics) and the exclusion case, routing MSP/contractor questions to get_partner_channel and Windows 365/AVD questions to get_cloud_pc_offering. The optional-filter condition is also stated inline.

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