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

Annotations already declare idempotentHint=true and destructiveHint=false, and the description reinforces this with 'mint (or reuse)' and 'stable link.' It adds context annotations cannot carry: that minting has no send side effect ('Nothing is sent') and that it is gated as 'Write tier,' which warns of permission requirements. Missing details on scope/expiry of the link keep it from a 5.

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?

One dense sentence front-loads the action and result, then packs the disambiguation, side-effect note, and tier. Every clause earns its place, though the embedded endpoint and 'Write tier' jargon make it slightly harder to scan than plain prose.

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 a one-parameter, non-destructive write with no output schema, the description covers what the agent still needs: the return is a link, the operation is reusable/idempotent, nothing is sent, and there is a follow-up tool. Only the auth/tier mechanics and link lifetime remain unspecified.

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 0% for the single list_id parameter, so the description must compensate. It does so only indirectly, by calling it 'a task list's' report and referencing the ':id' path segment, which implies list_id is a task-list identifier. That is enough to call correctly but no format or example is given.

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 ('Mint (or reuse)') plus resource ('a task list's completion report') and the resulting artifact ('get its link'), with the endpoint as corroboration. It explicitly separates itself from tascan_generate_report (same link type) and from a worker's shift report, so an agent can distinguish it from siblings without opening a schema.

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?

'Mint (or reuse)' signals call-anytime idempotent behavior, and 'Nothing is sent; text it with tascan_text_report' tells the agent the follow-up path for delivery. It doesn't spell out the precise condition selecting this over tascan_generate_report directly (the relationship is only implied via 'same stable link ... returns'), so it stops short of full when/when-not coverage.

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