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

With no annotations, the description must carry the behavioral burden. It does disclose two real traits: the result set includes failures (not just successes) and the operation is free/no-cost. It says nothing about authentication requirements, pagination, or result ordering, so coverage is partial.

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 purpose is front-loaded in the first line, which is good. However, the second paragraph is largely rhetorical justification ('a payout history that only shows successes is a claim, not a record') that consumes space which could have carried usage or parameter guidance.

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?

An output schema exists, so return-value explanation is unnecessary, and the description usefully states what the output contains (attempts, including failures) and that it is free. It still omits auth expectations and routing against closely related siblings, leaving gaps for a 3-param query tool with no annotations.

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 67%, and the description adds no parameter-level meaning at all. The npub, limit, and dpop_token semantics come entirely from the schema; the description neither clarifies dpop_token (undocumented) nor explains the required npub beyond the schema text.

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?

The opening line 'Every payment attempted, and how it went' gives a specific verb+resource (a history of all payout attempts) and the closing line clarifies it includes failures, not just successes. It is distinguishable from a success-only listing, but it never names or differentiates against the real siblings such as beesknees_settlement_history or beesknees_check_payment.

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?

There is no explicit when-to-use guidance or statement of alternatives. 'Free on purpose' hints at the no-cost condition, but nothing tells the agent when to reach for this tool versus beesknees_payout, beesknees_check_payment, or beesknees_settlement_history.

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