lookup

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

With no annotations, the description carries the behavioral burden. It discloses that this is a combined one-shot operation, returns full content of relevant segments, and groups results per part. It does not discuss side effects or permissions, but for a retrieval tool the disclosed behavior is sufficient.

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 focused sentences: the first defines what the tool does, and the second gives routing guidance. No wasted words, and the most important scoping detail is front-loaded.

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 only two parameters, full schema coverage, an output schema, and the description clarifies its relationship to key siblings. An agent has enough information to invoke it correctly and understand its grouping behavior without ambiguity.

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 adds little beyond the schema beyond reinforcing the grouping behavior tied to parts, which the schema already states.

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 states a precise action: one-shot retrieval of full datasheet segment content for one or more parts. It also differentiates itself from siblings by noting it fuses search and get_segments and groups results per part.

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?

Explicitly advises preferring lookup over search when the part(s) are known, giving a clear usage condition relative to a sibling. It does not enumerate exclusions or alternative comparisons for all siblings, but the guidance is actionable and specific.

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