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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so most of the safety profile is covered for free. The description adds that only unexpired, still-staged requests are returned and that the list is scoped to the caller's bound wallet, which is genuine extra context. It says nothing about result size, ordering, or what happens when the requesting agent lacks root status.

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, zero filler, and the scope constraint plus the named companion tool are front-loaded. Nothing is repeated from the title or annotations verbatim beyond necessary framing.

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?

With an output schema present and no parameters, the description only needs to establish what the list contains, whose it is, and what to do next — all of which it does. The only gap is behavioral edge cases (empty results, non-root callers) that a root-only onboarding tool arguably should mention.

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 of 4 applies; there is no schema surface the description needs to compensate for. The description correctly signals there are no filters by tying the result set entirely to the caller's identity.

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) and a precise resource (staged LinkConsent requests awaiting root approval), plus the scope restriction to the authenticated root agent's bound wallet. It doesn't explicitly contrast with a near sibling such as kellian_submit_link_consent, but the read/list framing separates it well enough at a glance.

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 names the follow-on tool (kellian_approve_link_consents) and the goal it serves (onboarding many agents headlessly), which tells the agent when this belongs in a workflow. It stops short of stating exclusion conditions, e.g. that non-root callers or already-approved consents are out of scope.

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