rattus_crc_self_test

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

No annotations are provided, so the description carries the full behavioral burden. It conveys a nondestructive verification operation and names the expected check vector, but it does not disclose how the result is returned, what failure looks like, or whether any firmware connection is required.

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 a single, front-loaded sentence with no filler. It efficiently includes the action, scope, algorithm, firmware counterpart, and expected result, with every element earning 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?

For a zero-parameter tool with no output schema, the description is nearly sufficient: it states the operation and the expected result. It does not explicitly explain pass/fail semantics or side effects, but these are relatively minor gaps for a diagnostic self-check utility.

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 is empty and schema description coverage is 100%, so there are no parameters the description must document. The expected check vector 0xA1 adds useful context about what the test validates without needing parameter-level detail.

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 states a specific action and resource: it verifies host-side CRC-8/MAXIM compatibility against firmware RattusUart. The expected check vector 0xA1 makes the purpose concrete and clearly separates it from the serial, compile, and board-management sibling tools.

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 'self-test' name and the 'Verify...' phrasing imply a diagnostic use case, but the description does not explicitly state when to run it or contrast it with alternatives. No prerequisites or exclusion criteria are given, so usage guidance is present only by implication.

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