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

Annotations already declare readOnlyHint=true/destructiveHint=false/openWorldHint=true, and the description adds real behavioral context on top: the 72-hour scheduling delay, the scheduled→processing→processed progression, the fact that a booking and its overtime can pay out separately, and the Cotlet API-key auth requirement.

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?

The opening fragment ('Payouts with date, amount, status and the bookings, overtime and add-ons in each') is awkward and the entry contents are stated twice; the auth note is appended after the lifecycle explanation rather than front-loaded. Still readable and moderately sized.

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 carries the return-value burden and does describe entry contents and the payout state model, and it flags the auth prerequisite. It is nearly complete for a simple read-only list tool, though filtering behavior is left entirely to the schema.

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 the schema already documents both parameters; the baseline is 3. The description does add meaning to the status enum by tying scheduled/processing/processed to lifecycle stages, but it adds nothing for the 'since' filter.

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 ('Lists the payouts from your payout dashboard') and enumerates what each entry carries (date, amount, status, bookings, overtime, add-ons). No sibling peerspace tool returns payouts, so it is trivially distinguishable from the rest of the namespace.

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?

The description explains the payout lifecycle but never says when this tool should be chosen or what conditions select it (e.g., use status=processing to reconcile, since=... for a period). No when-not guidance or references to alternatives are given.

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