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 discloses a cost (0.003 USDC) and a mutation-like action (signing), but says nothing about permissions, reversibility, idempotency, or what the signature means. For a signing/payment operation with zero annotation coverage, this is a significant gap.

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?

A single tight sentence front-loads the verb and resource and appends the cost. No waste, no filler, and the essential transaction trait (price) is not buried.

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?

The tool involves signing and a fee, and it has an output schema, so return values need not be explained. But the absence of any behavioral context for a paid signing operation leaves an agent under-informed about prerequisites and consequences, making this only minimally complete.

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?

Schema description coverage is reported at 100%, though the input schema itself is terse. With high schema coverage, the baseline is 3 even though the description adds no parameter-level detail beyond the implied 'results' input.

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?

States a specific verb ('Compare') and resource ('agent results') and adds the action taken ('sign agreement or conflict'), which distinguishes it from neighbors like conflict_resolution and verify. It is clear what the tool does, though it doesn't explicitly name which sibling it is not to be confused with.

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?

There is no when-to-use, when-not-to-use, or alternative routing guidance. The description mentions the output artifact (signed agreement/conflict) but not the scenario that calls for this comparator over related tools such as conflict_resolution.

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