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

With no annotations, the description must fully disclose behavioral traits. It states it 'analyzes' and 'generates' but does not disclose side effects (e.g., file creation, overwriting), permissions needed, or output format when no output_path is provided. The absence of output schema details further limits transparency.

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 with no fluff. The first sentence captures the core purpose, and the second adds context. Every sentence earns its place.

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 simplicity (3 params, all documented) and the presence of an output schema (though not shown), the description is moderately complete. However, it could be improved by stating that a valid schematic is required and clarifying the default behavior when output_path is empty. The description is adequate but has gaps.

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?

All three parameters are described in the input schema with 100% coverage. The description adds no additional meaning beyond the schema definitions. Baseline score of 3 applies as schema already documents parameters adequately.

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 generates a .dts file from a KiCad schematic for a specified SOC family. It uses a specific verb ('generate') and resource ('device tree source file'). However, it does not explicitly differentiate from sibling tools like extract_gpio_config or extract_pinmux_config, which extract specific parts of the device tree.

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 lacks any guidance on when to use this tool vs. alternatives. It does not mention prerequisites (e.g., must have a valid KiCad schematic), nor does it provide context for choosing this over sibling tools that extract specific configurations.

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