write_peripheral_register

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

No annotations provided; description only states it writes a value. It lacks disclosure of side effects, permissions, error handling, or destructive nature, which is critical for hardware writing.

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?

Single, front-loaded sentence with no unnecessary words. Efficiently states purpose and example.

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 2 parameters, the description provides core functionality. However, it lacks validation details (e.g., invalid register names) and does not reference the existing output schema, though that is optional.

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?

Description adds context for 'name' (example format) and 'value' (32-bit), but with 0% schema coverage, it does not specify value format (e.g., hex) or constraints, leaving ambiguity.

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?

Description clearly states the tool writes a 32-bit value to a peripheral register by name, with an example ('GPIOA.ODR'). It distinguishes from siblings like write_memory and write_register by specifying peripheral registers.

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 name and description imply usage for writing to peripheral registers, but there is no explicit guidance on when to use this tool versus alternatives like write_memory, write_register, or write_variable.

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