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

With no annotations, the description carries the full burden and does well: it discloses that blank trust/hope/value/challenge scores are estimated from industry benchmarks, and it explains the two-phase paid-access model including the license_key alternative. It omits any statement about rate limits, data retention, or what happens on invalid credentials, so it is strong but not exhaustive.

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 purpose sentence is front-loaded and the argument list is dense and scannable, with no filler prose. The Args block is somewhat list-like, but each line delivers distinct parameter information rather than restating the schema.

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?

Because an output schema exists, the description need not narrate return values, and it focuses correctly on inputs and the access/payment flow. All ten inputs are covered and the two-call pattern is explained, though the agent receives no hint about prerequisite data quality or expected response shape beyond the 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 description coverage is 0% (properties carry only titles and empty-string defaults), so the description must compensate and does: it explains every one of the ten parameters, including the 0–5 scale and optionality of the four dimension scores, the benchmark fallback, and the exact roles of payment_proof and license_key. This is materially more meaning than the bare schema provides.

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 and resource: diagnosing organizational vitality and producing a four-dimension (trust/hope/value/challenge) construction plan with an implementation checklist. This is far more informative than a tautology, and the concrete deliverables make the tool's output identifiable. It does not, however, distinguish itself from siblings like tbp_problem_solving or cost_improvement, leaving an agent to infer the boundary.

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 gives clear operational context for the payment-gated flow: a first call with payment_proof empty returns payment information, and the caller retries with proof after paying, or supplies license_key to bypass payment. This is genuine when/how guidance for actually invoking the tool. It offers no guidance, though, on when this diagnosis is preferable to the sibling problem-solving or quality tools.

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