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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful context about what the call returns (services, engagement model, next step), but says nothing about how budget/timeline influence the result, whether the brief is stored, or output structure beyond a bare list.

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 sentence with zero filler, front-loading the input ('Given a short project brief') before the outputs. Every clause earns its place.

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 no output schema, the description carries return-value burden and does partially discharge it by enumerating the three outputs. However, it leaves the two optional parameters entirely unexplained and gives no guidance on how results should be acted on versus calling submit_inquiry.

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 only 33%: 'brief' is documented in the schema, but 'budget' and 'timeline' have no descriptions anywhere. The description mentions only 'a short project brief' and does not compensate for the two undocumented optional parameters or explain their format (e.g., free text vs numeric range).

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 names a specific verb ('return') and three concrete outputs (best-matching services, engagement model, next step) scoped to an input brief, so the tool's function is unambiguous. It does not, however, distinguish itself from siblings like list_services or submit_inquiry, which also touch services and engagement.

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 phrase 'Given a short project brief' implies the trigger condition, so usage is inferable, but the description never states when to prefer this over list_services or when to move on to submit_inquiry, and it offers no exclusions.

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