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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds real value by disclosing the return shape (deterministic result plus an unmeasured savings receipt), but the advertised 'Limits' are only a bare URL rather than an actual disclosure of rate or size constraints.

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?

Three tight sentences with the action front-loaded, followed by return behavior and a limits pointer. No filler, though the trailing URL sentence conveys little on its own.

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?

An output schema exists, so return values need not be fully spelled out, and annotations carry the safety profile. However, for a generic dispatcher with a free-form nested 'input' object, the description omits error behavior, validation expectations, and the actual limits it points to, leaving meaningful gaps.

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 only 25% (just the optional 'model'), so id, version and input are undocumented in the schema. The description partially compensates by clarifying that id/version identify the catalog tool and input is that tool's JSON payload, but it says nothing about format, validation, or what a missing/unknown id does.

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: 'Run one ComputeFirst catalog tool by id and version with its JSON input.' The word 'one' implicitly contrasts with the sibling execute_batch, so an agent can reasonably separate the two, though the sibling is never named outright.

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 only implied by the word 'one' (i.e., use execute_batch for several) rather than stated. There is no guidance on when to call describe/search/list_saved_tools first, or on prerequisites for having a valid id/version pair.

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