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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so the safety profile is covered. The description adds useful behavior beyond that: it discloses that results are limited to pending/staged consents tied to the caller's own bound wallet, which is a real scoping constraint an agent would not infer from the annotations alone.

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 sentences, both load-bearing: the first defines scope and resource, the second routes to the paired approve tool. Query intent is front-loaded with no redundant restatement of the title.

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 zero-parameter read tool with full annotation coverage and an output schema, so return values need no explanation. The description covers what is listed, whose consents they are, and what to do next; only pagination/bounding behavior and the 'unexpired' filter mentioned in the title are 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?

The tool takes zero parameters, so the baseline is 4. Nothing in the description is needed to explain inputs; the scoping is entirely implicit in the authenticated identity, which the description does make clear.

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 (List), a specific resource (staged LinkConsent requests awaiting root approval), and a precise scope (the authenticated root agent's bound wallet). An agent can distinguish this from the approve sibling, which is named explicitly as the follow-up action.

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?

Gives clear operational context: this is the read step in the headless onboarding flow, and it directs the agent to problee_approve_link_consents as the next step. It stops short of stating when-not to use it (e.g., if the caller is not a root agent) but the precondition is implied by the scope clause.

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