check_binary_diff

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

The description discloses that the tool always returns 'status: OK' and has no external dependencies, which is useful behavioral context beyond a typical read operation. However, it does not specify the format or content of the version string.

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, with two sentences that front-load the key purpose and a notable characteristic (no dependencies). Every sentence adds 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?

Given no parameters, no output schema, and no annotations, the description is fairly complete but lacks explicit details about the return structure (e.g., is version a string? object?). Minimal viable score.

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?

There are no parameters, so the description cannot add meaning beyond the schema. Baseline of 4 applies as there are no gaps.

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 it returns server status and version, with a specific verb 'Return' and resource. However, it does not differentiate from sibling tools like fingerprint_sections or unified_diff, which are likely diffing 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?

No guidance is provided on when to use this tool versus alternatives. The description implies it's a health check, but lacks context such as prerequisites or typical usage scenarios.

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