szlcsc_sync_datasheets

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

No annotations are provided, so the description must disclose behavioral traits. It mentions 'incrementally maintain' and 'sync', which implies non-destructive updates, but it does not explain whether it overwrites existing files, requires authentication, handles errors, or has rate limits. Critical behavioral information is missing given the absence of annotations.

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 a single short sentence, which is concise. However, it lacks structure (e.g., no front-loading of key details). It packs the core purpose and a usage hint in one line, so every word earns its place. It could be slightly more structured but is efficient.

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?

Given no annotations, low schema coverage, and the presence of an output schema, the description is incomplete. It does not explain the return value (the output schema exists but is unmentioned), prerequisites, or how the batch sync behaves. An agent would need to infer too much to use this tool correctly.

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 has three parameters (identifiers, force, output_dir) with 0% description coverage. The description does not explain any parameter—neither the required 'identifiers' nor the optional 'force' and 'output_dir'. Without schema descriptions, the agent must guess the meaning of these parameters.

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 tool's purpose: batch syncing datasheets to a directory and incrementally maintaining a manifest.json. This is a specific verb-resource pair that distinguishes it from siblings like szlcsc_download_part (single download) or szlcsc_search (search). However, it does not explicitly differentiate from szlcsc_download_parts, which could also be used for batch downloads.

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 mentions it is 'suitable for BOM/MPN list', giving context for when to use it (for lists of part numbers). However, it provides no guidance on when not to use it or what alternatives exist (e.g., using szlcsc_download_part for single parts). The guidance is implied rather than explicit.

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