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

With no annotations, the description carries the full burden, and it does disclose useful behavior: the call is free and returns a price quote before any payment is made. It omits auth requirements, whether the offer is binding, and what happens for invalid goals, so the behavioral picture is only partially filled in.

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?

Two short sentences, front-loaded with the tool's role and the value it returns. No filler, though the undefined 'PAL' term costs a little clarity.

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?

A routing tool with a 4-value required enum, a second bounded integer, no annotations, no output schema and 0% schema coverage needs the description to explain the goal taxonomy and the seller_count meaning. It instead stays at the marketing level, leaving the agent unable to map intent to the correct enum value.

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%, and the description says nothing about either parameter. The required 'goal' enum (repair_one, audit_portfolio, generate_launch_bundle, go_live_and_distribute) is the key routing input and is never explained; only the phrase 'launching or repairing' loosely gestures at two of its values. 'seller_count' and its 1-5 bounds are also unexplained.

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 states a concrete action (return the right PAL offer plus an exact USDC price) and scopes it to providers launching or repairing a paid agent service. However, 'PAL' is undefined jargon and nothing distinguishes this from the sibling recommend_catalog_offer, so an agent cannot confidently pick between them from the text alone.

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?

It gives a target audience and timing ('providers launching or repairing a paid agent service') and emphasizes 'before any payment', which implies a pre-purchase step. But it never names an alternative or states when NOT to use it, and the sibling recommend_catalog_offer is left unaddressed.

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