serial.plugin.template

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states the tool returns a template, implying a non-destructive read-only operation, but does not explicitly guarantee no side effects or state changes. The optional device name pre-fill is noted, and the lack of warnings for destructive behavior is acceptable given the template generation nature.

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 consists of three sentences, each with a distinct purpose: stating the tool's function, its usage scenario, and the follow-up workflow. It is front-loaded with the key action and efficiently provides necessary context without redundant 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?

For a simple tool with one optional parameter and no output schema, the description covers its purpose, usage context, and follow-up steps. It mentions the sibling tool for loading and the file path. However, it does not explicitly state the return type (e.g., a string with Python code), which would slightly enhance completeness.

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?

Schema coverage is 100% for the single parameter, so the baseline is 3. The description mentions 'Optionally pre-fill with a device name,' which aligns with the schema description but adds no additional constraints or formatting details. The parameter meaning is adequately conveyed without extra enrichment.

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 'Return a Python plugin template' and distinguishes from siblings like serial.plugin.load by specifying 'Use this when creating a new plugin.' The verb 'Return' and resource 'Python plugin template' are specific and actionable.

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 explicitly says 'Use this when creating a new plugin' and provides a step-by-step workflow: save to file, fill in tools/handlers, then load with serial.plugin.load. This gives clear guidance on when to use and how to proceed, effectively distinguishing from sibling tools.

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