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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description still adds value by naming the accepted artifacts returned (terms_accepted, rights_declared_asset_ids) and by implying a polling/eventual-consistency model with an 'expired' terminal state, none of which the annotations convey.

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?

Front-loaded with the result contract, then the behavioral note, then the argument shape; three tight sentences with no filler. The embedded Arguments snippet partially duplicates the schema but is justified given zero schema coverage.

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 no output schema, the description successfully covers the return contract (three statuses plus accepted fields) and the call pattern. Remaining gaps are minor: no guidance on polling cadence, expiry window, or follow-up actions after 'confirmed'.

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 coverage is 0% and the nested 'path.id' property carries no description, so the description must compensate; it does by showing the literal argument shape and labeling the id as a '<confirmation_id>'. It still does not say where that id comes from (presumably the request_confirmation response), which keeps it from a 5.

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 ('Read a confirmation link's status') and enumerates the exact outcomes (pending, confirmed, expired), so an agent immediately knows what it gets back. This clearly separates it from the sibling that creates such links (kelpo_request_confirmation).

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?

'poll it after sharing the link' gives explicit timing guidance: call this after distributing the confirmation link to check whether the counterparty accepted. There is no statement of when not to call it or which sibling to use instead, so it falls short of a 5.

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