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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior, so the safety profile is fully covered structurally. The description adds an operator enumeration and the notion of optional filtering, but nothing about execution behavior, result size, or unknown-field handling. Adequate but not rich.

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?

Two tight sentences, front-loaded with the core action. The operator list is somewhat redundant with the schema enum, which keeps it from a 5, but there is no filler.

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 read-only query tool with no output schema, the description should ideally say something about the shape/size of results or the effect of the limit. Instead it covers only input-side concerns, leaving the agent to infer return behavior entirely.

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 baseline is 3. The description repeats the operator list already present as an enum in the schema and does not clarify ambiguous operators such as 'co' (contains?) or how value typing works for gt/lt. It adds no meaning beyond the schema.

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: 'Query records from a table with optional filtering.' This clearly distinguishes it from the insert/delete/update record siblings in the list. It lacks any explicit naming of those siblings, so it stops short of a 5.

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 guidance on when to use this versus ap_delete_records, ap_insert_records, or ap_update_record, nor any note about pagination or how to handle large result sets. The only usage signal is the indirect 'optional filtering' phrase. Context is implied, not stated.

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