-}New value: +nullDoes the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false. The description adds real behavioral context beyond them: no payment method is charged, and certain package classes are not available. It stops short of saying whether the link expires or is single-use, which keeps it from a 5.
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?
Four short sentences with zero waste, front-loaded with the outcome and then the constraint, prerequisite, and safety note. Every sentence 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?
For a one-parameter, closed-world read tool with no output schema, the description covers what it returns (checkout link and fixed price), the required input provenance, availability limits, and the no-charge guarantee. Only the link's lifetime/one-time-use behavior is left unstated.
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%, but the single parameter is a required identifier with a regex pattern in the schema. The description compensates by stating the value must be exact and naming the tool that produces it (gisdb_search_catalog), which is meaningful guidance beyond the pattern alone.
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 ('Get the buyer checkout link and fixed price') plus the eligible scope ('available records product'). It also names the sibling that supplies the required input (gisdb_search_catalog), so an agent can distinguish it from the catalog search without opening either schema.
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?
Explicitly states the prerequisite ('Requires its exact product_id from gisdb_search_catalog') and the exclusion ('CAD and statewide packages remain unavailable unless separately released'). It lacks a naming of a direct follow-up or alternative sibling for the checkout step itself, but the when-to-use context is clear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
