Get Datasheet Url

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

Annotations already mark the tool as read-only and idempotent, and the description adds important behavioral context: the URL is constructed locally without a network request. It also discloses the exact return payload (PDF URL and product page URL). This exceeds the annotation baseline.

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 compact and well-structured, leading with the core purpose and adding only essential details: return values, network behavior, and a clear example. No redundant or tangential content.

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 tool with one parameter and rich annotations, the description fully explains the operation's purpose, behavior, and outputs. The presence of an output schema (implied) and example make it complete.

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 schema provides full coverage of the single 'lcsc' parameter, including format details and example. The description's example reinforces the parameter usage but does not add substantial semantic information 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?

The description uses the specific verb 'Get' with the resource 'LCSC datasheet URL for a component by LCSC number', clearly stating what is returned. It distinguishes from sibling tools like search_jlcpcb_parts or get_jlcpcb_part by specifying the URL construction method and the no-network behavior.

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 implies the tool is for retrieving a datasheet URL when you have an LCSC part number, and the 'No network request' note suggests it's suitable for quick, offline URL construction. However, it does not explicitly name alternative tools or exclusionary conditions, so it falls short of full guidance.

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