Export BOM

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

Annotations indicate readOnlyHint=false and destructiveHint=false, so the tool is a write operation but not destructive. The description adds that it writes to a file on disk, providing context beyond annotations. However, it does not disclose potential side effects like overwriting existing files or required permissions.

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 sentence with no wasted words. It is front-loaded with the action and resource. However, it is overly terse and omits parameter details, so it sacrifices completeness for brevity.

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 the tool has 3 parameters (2 required), no schema descriptions, and an output schema (not shown), the description should provide more guidance on parameter usage and expected output. It fails to compensate for the lack of schema descriptions, making the tool definition incomplete.

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 has 0% description coverage, meaning no parameter descriptions in the schema. The description fails to explain any parameters: it does not mention projectId, filePath, or the format enum (csv, json, xlsx). This leaves the agent without crucial information for correct invocation.

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 'Export' and the resource 'bill of materials' to a file, with the specified format. This distinguishes it from sibling tools like easyeda_bom_generate or easyeda_bom_validate, which focus on generation or validation rather than file export.

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 usage for exporting a BOM to a file, but it provides no explicit guidance on when to use this tool versus alternatives such as easyeda_bom_generate or easyeda_bom_sourcing. No exclusions or prerequisites are mentioned.

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