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

No annotations are provided, so the description carries the full disclosure burden. It usefully names the four tier outputs it produces, but says nothing about whether this is a pure calculation or persists state, what permissions it needs, or how acquisition_cost changes behavior.

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 that front-loads the core purpose and packs the four generated tier types without any filler. 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 helpfully enumerates the tier outputs, but it omits how tiers are derived, whether acquisition_cost materially alters the result, and any auth or side-effect context. Adequate but with clear gaps for a pricing-calculation tool.

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% with only two parameters, so the schema already documents both domain and acquisition_cost. The description adds no format, range, or effect details beyond the schema, making the baseline 3 appropriate.

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 gives a specific verb ("Generates") and resource ("strategic pricing tiers for a domain") and enumerates the exact outputs: BIN, Make Offer floor, Auction reserve, and 12-month lease price. It does not, however, distinguish itself from the sibling forecast_renewal_roi, leaving that separation to inference.

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?

There is no statement of when to use this tool, when not to, or which alternative to pick. The sibling forecast_renewal_roi is never mentioned, and no preconditions (e.g., domain must be owned) are given, so usage must be inferred from the purpose sentence alone.

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

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

With no annotations, the description carries the full burden. It does add a genuine behavioral fact not derivable from the schema – that results are produced across three fixed horizons – but says nothing about whether the operation is read-only, what the output shape is, or any assumptions (currency, rate basis). Adequate but thin for an annotation-free tool.

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 front-loaded sentence with no filler; the scope (horizons) comes right after the computation. It could be marginally clearer but nothing is wasted.

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 two-parameter calculation tool with no output schema, the description explains what is computed but not what is returned (a ratio, a dollar figure, a comparison table) or how the three horizons are presented. The absence of an output schema means the description should have covered the return value, which it does not.

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 both parameters (annual_renewal_usd, target_sale_price_usd) are already documented in the schema. The description's terms 'holding cost' and 'target flip multiple' loosely map to them but add no syntax, units, or format detail. Baseline 3 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?

States a specific verb (Calculates) and the exact quantities compared (holding cost vs target flip multiple) plus the scope (1, 3, and 5 year horizons). An agent can grasp what it computes, though it never differentiates itself from the sibling calculate_pricing_tiers.

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?

There is no when-to-use guidance, no preconditions, and no mention of the sibling calculate_pricing_tiers as an alternative. The agent is left to infer the scenario from the name alone.

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