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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions 'propose' and 'rate' as actions but does not disclose side effects, permission requirements, reversibility, or result format. The high-level phrasing leaves significant behavioral gaps.

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 sentence with clear front-loading: 'Deal Handshake' captures the essence, followed by concrete actions. Every word earns its place; no wasted content.

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 has 3 parameters, no output schema, and no annotations. The description covers the core purpose but omits usage context, return values, and behavioral nuances. It is minimally adequate but not fully complete for a commerce-related tool.

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 100% (each parameter has a description: did, tool, action). The description adds no extra parameter detail beyond the schema, but the enum for action is clear. Baseline of 3 is appropriate since the schema handles parameter meaning.

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 ('propose a deal, get terms, rate') on a resource ('deal') and adds context with 'Agent-to-agent commerce.' It is clear and somewhat distinguishes from siblings by using 'handshake' terminology, though it does not explicitly name alternative 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 description implies use for agent-to-agent deal-making but does not explicitly say when to use this tool versus siblings like quantum_offer or quantum_settle. No alternatives or exclusions are mentioned, leaving the context implied rather than explicit.

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