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 notes the escrow payment flow and zero platform fees, but does not disclose required wallet signature authentication, nonce handling, irreversibility, or failure modes.

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 short and front-loads the core action. However, the trailing 'Free peer-to-peer: 0% platform fees' sentence is promotional rather than actionable for selecting or invoking the tool, so not every sentence earns 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 financial mutation tool requiring signature auth with no annotations, no output schema, and 0% parameter coverage, the description is insufficient. It omits authentication requirements, side effects, and result expectations.

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 coverage is 0% for four required parameters (id, wallet, nonce, signature), and the description adds no meaning for any of them. It does not explain what the wallet, nonce, or signature must contain.

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 (buyer accepts) and a concrete consequence (escrow pays the seller), making the core purpose clear. It does not explicitly name the resource 'task' nor distinguish this tool from sibling accept_offer, leaving some ambiguity about when to choose it.

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 accept_offer, claim_task, or other siblings. The description is silent on prerequisites, timing, or exclusions.

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