verify_hex

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

Describes return value 'PASS' and error on mismatch. No annotations provided, so description carries full burden; it adequately discloses behavior with no contradictions.

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?

Three concise sentences: purpose, parameter and return behavior, usage context. No wordiness, all sentences add value.

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?

While purpose and return are clear, the tool has 6 parameters and an output schema; description fails to address the connection-related parameters, leaving ambiguity about how to use the tool correctly.

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?

Only hexfile is explained (absolute path). Five other parameters (device, tool, serialnumber, serialport, baudrate) are left undocumented despite 0% schema coverage. This is a major gap.

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?

Clearly states 'Verify that target device memory matches an Intel HEX file.' Verb+resource is specific and distinguishes from write_hex (write) and read_memory (read but no comparison).

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?

Explicitly says 'Use after write_hex or to audit an already-programmed device.' Provides clear context for when to use, though doesn't explicitly mention when not to use.

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