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

Annotations supply destructiveHint=true, so the safety bar is lower, and the description earns credit by disclosing the concrete consequence of approval: the partner gains links and starts earning commission. It stops short of saying whether the action is reversible or what state the application must be 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?

Three short sentences, front-loaded with the action and its consequence, with the endpoint appended as useful orientation. No filler, though the endpoint string adds little for an agent that already has the tool bound.

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 an irreversible-ish mutation with no output schema and only a destructiveHint annotation, the description covers the effect but omits reversibility, idempotency, required application state, and permission needs. It is adequate but leaves the caller to infer operational constraints.

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 100%, so both applicationId and groupId are already documented in the schema; the description adds nothing beyond that. Baseline 3 applies when the schema carries the parameter semantics.

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+resource ('Approving an application to join the partner programme') and even notes the downstream effect. It is clear what the tool does, though it never names its obvious sibling dub_reject_partner_application, so sibling differentiation is left 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?

Usage is implied by the name and the described consequence, but there is no explicit when/when-not guidance and no pointer to the counterfactual action (reject) or any prerequisite state (e.g. the application must be pending).

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