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

Annotations already cover the read-only, idempotent, non-destructive safety profile, lowering the burden on the description. The description adds useful retrieval behavior: the source and page scope, the optional keyword filter, and the exact default cardinality of all sixteen Q&A pairs.

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 entire description is one compact sentence that moves from resource to filter behavior to default behavior without filler. Every clause contributes information needed to invoke the tool correctly.

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-optional-parameter, read-only tool with no output schema, the description fully covers what is returned, where it comes from, how to filter it, and what happens when the query is empty. No critical invocation information is missing.

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?

The input schema already covers the single query parameter at 100%, including concrete examples, so the baseline is 3. The description reinforces that the parameter is an optional filter and adds the empty-query default, but it does not introduce new semantics like matching rules or output formatting.

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 identifies the resource (Q&A pairs from specific site sections) and the filtering behavior, so it is not a tautology. It lacks an explicit verb like 'retrieves' and does not differentiate itself from siblings such as search_micah_boswell, so it does not fully earn 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?

The only usage guidance is for the query parameter: optional keywords filter the results, and leaving it empty returns all sixteen. There is no statement about when to prefer this tool over the sibling content or search tools, so tool selection is left mostly to inference from the name and content.

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