upload_gerbers_for_quote

Upload a gerber zip file to receive a PCB fabrication quote. Track processing status with the returned job ID.

Instructions

Upload a gerber zip file to get a fabrication quote.

Reads the gerber zip from disk and submits it for fabrication quotation. Use check_manufacturing_status with the returned job_id to track progress.

Behavior3/5

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

With no annotations, the description carries the burden. It indicates a write operation that reads from disk, but it does not disclose authentication requirements, file size limits, or what happens to the file after upload. It mentions returning a job_id implicitly but misses behavioral details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise with two sentences. It front-loads the purpose and adds a clear follow-up instruction. No unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

While the description covers basic purpose and follow-up, it lacks details on prerequisites (e.g., file accessibility, format validation), potential errors, and output structure beyond job_id. For a tool with 7 parameters, more completeness would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description does not add any parameter-specific context beyond what the schema already provides, such as allowed values for 'surface_finish' or 'color'.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('upload a gerber zip file'), the purpose ('get a fabrication quote'), and the process ('reads from disk and submits'). It distinguishes from siblings like 'upload_bom' and hints at the follow-up tool 'check_manufacturing_status'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context (when you have a gerber zip file and want a quote), but it does not explicitly state when not to use this tool or mention alternatives like 'quote_fabrication'. It provides some guidance via the follow-up action but lacks exclusions.

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