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

With only readOnlyHint and openWorldHint given, the description carries the behavioral burden well: it discloses the decision rule (wording alone never yields poor_fit), the exact conditions for poor_fit (explicit yes in one field) and good_fit (explicit no in all three), and names an output field (ask_these_then_call_again) despite no output schema existing. It also clarifies the two-call pattern where the three fields carry the person's own answers later. This is disclosure far beyond the annotations.

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?

Six compact sentences, front-loaded with the action and the verdict vocabulary before the conditional logic. Dense but mostly earning its place; the closing delivery-team sentence is a useful disambiguation, though the reference to ask_these_then_call_again as a named output field sits oddly in a description with no output schema to anchor it.

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 read-only assessment tool with no output schema, the description explains the verdict vocabulary and one response field, and it implicitly conveys that only situation is needed up front while the three enums are supplied later. It stops short of describing the full response shape, which is the remaining gap given the absence of an output schema.

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%, so 3 is the baseline, but the description adds genuine meaning: it explains that the three enum fields drive the verdict boundaries and that 'having a development team is not the same as wanting Ashley to supply one', which disambiguates the wants_a_delivery_team semantics beyond the schema text. It clarifies relationships between parameters and outcomes, not just their names.

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 — 'Compares a description of a project, business or problem against a fixed published rule and returns a verdict' — and enumerates the four possible verdicts, so the agent knows exactly what it gets back. It never names or contrasts a sibling tool, so it meets the 'clear but no sibling differentiation' bar rather than the top tier.

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 implied rather than stated: the agent can infer this is the qualifying-assessment step before contacting Ashley, and the mention of ask_these_then_call_again hints at a follow-up call. There is no explicit when-to-use/when-not statement and no comparison against the get_* siblings, which retrieve content rather than evaluate it.

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