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

No annotations are provided, so the description must disclose behavioral traits. It mentions pagination behavior ('Transparently paginates to collect up to `limit` records'), which is helpful. However, it does not disclose read-only nature, authentication requirements beyond requiring 'persona', rate limits, or error handling. For a query tool, more transparency about side effects and constraints would be beneficial.

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 description is two sentences, front-loaded with purpose and immediately followed by a key behavioral detail (pagination). Every word adds value; no fluff or repetition. It is a model of conciseness.

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?

The tool has 9 parameters (1 required) and an output schema. The description covers the core purpose and pagination behavior, but lacks explanation of the required 'persona' parameter (what is a persona?), does not mention output format or fields, and provides no examples or use-case context. For a complex filtering tool, the description leaves gaps in completeness.

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 parameters are already documented in the schema. The description adds context about the 'limit' parameter by explaining pagination behavior ('Transparently paginates...'). For other parameters, the description adds no additional meaning beyond the schema. Baseline 3 is appropriate.

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 description clearly states the tool queries QSOs from a QRZ logbook with optional filters. The verb 'Query' and resource 'QSOs from a QRZ logbook' are specific. It distinguishes itself from siblings like qrz_lookup (individual call lookup) and qrz_download (ADIF download) by focusing on logbook QSO retrieval.

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 mentions transparent pagination up to a limit, which gives some usage context. However, it does not explicitly state when to use this tool versus alternatives (e.g., qrz_lookup for single callsign queries, qrz_download for full log downloads). No when-not-to-use guidance or alternative suggestions are provided.

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