cache_aba_pull

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

With no annotations, the description carries the burden of behavioral disclosure. It usefully mentions that subsequent calls skip duplicates, implying idempotency, but it does not disclose side effects, authorization needs, or whether existing cache is overwritten. This leaves some gaps.

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 concise and front-loaded: purpose, parameter syntax, usage context, and a key behavioral guarantee are covered in just a few sentences. Every sentence adds value with no redundancy.

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 simple one-parameter tool with no output schema and no annotations, the description covers purpose, parameter format, when to use, and a key behavioral note. It does not describe return values or error cases, but those are not critical for this level of complexity.

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 has zero description for 'pages', but the tool description fully compensates by specifying the range format with examples ('1-500', '750-2500') and a default. This provides complete, actionable semantics for the single parameter.

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 verb 'Pull and cache' and the resource 'ABA keyword_list pages', with a specific scope ('pages' range). This distinguishes it from sibling cache_* tools by indicating it is the ingestion/population tool, not querying, status, or clearing.

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 gives an explicit 'USE THIS TOOL WHEN' condition (building local keyword cache for offline analysis) and advises to run once per page range. It lacks explicit when-not or alternative naming, but the context among siblings is clear enough.

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