printer_snapshot

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

No annotations are provided, so the description bears the full burden. It discloses automatic protocol detection and the two output modes (save path or base64). However, it does not mention whether the operation is read-only, any potential side effects, or required permissions. The description covers basic functionality but lacks deeper behavioral context.

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 very concise and front-loaded. The first sentence states the core purpose, followed by essential details on protocols and parameter behavior. Every sentence adds value with no wasted words.

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 two optional parameters and no output schema, the description covers the main aspects: capture action, supported protocols, and parameter behavior. However, it misses details like the image format of the base64 string or any prerequisites (e.g., printer must be online). For a tool with many similar siblings, it is reasonably complete but could be slightly enhanced.

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?

With 0% schema description coverage, the description compensates fully. It explains both parameters clearly: 'printer_name' as target (omit for default) and 'save_path' as optional save location (otherwise base64). This adds significant meaning beyond the schema's type/nullable constraints.

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 captures a webcam snapshot from the printer, specifying the verb 'Capture' and the resource. It lists supported protocols (Bambu A1/P1, OctoPrint/Moonraker, RTSPS for Bambu X1), distinguishing it from siblings like 'webcam_stream' and 'analyze_print_snapshot'.

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 provides some context by detailing the automatic handling of different protocols, but it does not explicitly state when to use this tool over alternatives like 'webcam_stream' or 'monitor_print'. No usage exclusions or conditions are mentioned.

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