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

No annotations are provided, so the description carries the behavioral disclosure burden. It discloses that the output is 'educational, illustrative planning output only' and lists what the tool does not produce, which is valuable for setting expectations. However, it does not describe whether the tool persists data, the accuracy of answers, required question coverage, or what happens if the caller supplies partial answers, even though the schema says 'any subset'.

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?

The first sentence clearly states the function and output, and the second sentence bundles important disclaimers. The enumeration of report sections is somewhat long but valuable because it tells the agent what the returned brief will contain. No redundant phrases or filler.

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 24 optional parameters and no output schema, the description does a good job of describing both inputs and output format. It is not fully complete because it does not describe error or fallback behavior for partial inputs, nor does it explicitly state the relationship to get_readiness_planner_meta (though the input schema points there). Overall, an agent can invoke this tool with reasonable confidence.

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%, so the schema already documents all 24 parameters individually. The description adds the overall semantics of 'normalized assessment answers' and the mapping to the readiness brief, but it does not enumerate or explain accepted value formats beyond what the schema provides. This meets the baseline 3 for high schema coverage.

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 ('Evaluates'), a specific resource ('custom-home or major-remodel project'), and a concrete deliverable ('personalized Project Readiness Brief'). It also enumerates the report's sections, which differentiates it from the sibling metadata tool.

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 description clarifies that the input is 'normalized assessment answers (q1-q24)' and that the output is educational planning output, not a quote or binding estimate. It does not explicitly state when to choose this tool over get_readiness_planner_meta, but the schema description's pointer to get_readiness_planner_meta for accepted values partially covers that routing. A clearer when-to-use comparison would push this to 5.

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