validate_pin_configuration

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

With no annotations, the description bears full responsibility for disclosing behavior. It only says 'validates and reports conflicts' but does not clarify if the tool is read-only or if it mutates state, nor does it describe the output format or any rate limits. A critically important behavioral trait is missing.

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 extremely concise: two sentences directly addressing purpose and behavior. No filler or redundant information. The most important information (validation for device tree generation) is front-loaded in the first sentence.

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?

Despite having an output schema (not shown), the description does not mention what the output contains (e.g., list of conflicts, severity). For a validation tool, the nature of the output is crucial for the agent to understand the result. The description omits this context.

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 already provides a complete description for the single parameter 'schematic_path'. The tool description adds no additional semantic value beyond what the schema offers. Given 100% schema coverage, a baseline score of 3 is appropriate.

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 'validate' and the resource 'pin configuration conflicts for device tree generation', making the tool's purpose specific. It differentiates from generic conflict detection by tying it to device tree generation. However, it does not explicitly distinguish from the sibling 'detect_pin_conflicts' tool, leaving mild ambiguity.

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 no guidance on when to use this tool over alternatives like 'detect_pin_conflicts' or 'extract_pinmux_config'. There is no mention of prerequisites, context, or exclusion criteria, which would help an agent decide correctly.

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