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

Annotations already carry readOnlyHint=false, destructiveHint=true, idempotentHint=false, and openWorldHint=true. The description adds meaningful behavioral context by disclosing that the tool creates and funds an escrow with USDC and then executes the task. The schema-level description further clarifies that the buyer agent is derived from the authenticated principal, not from arguments. No contradiction with annotations.

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 two sentences with the core action front-loaded and the rest as a compact, unambiguous pipeline list. Every clause adds information, and there is no redundancy with the schema or annotations.

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 complex, financially destructive bridge, the description covers the workflow, the intended caller context, and the separation between derived principal and arguments. An output schema exists, so return-value detail is unnecessary. Slightly more explicit guidance about when to choose the multi-step escrow/funding path instead would make it fully 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 100%, so each parameter is already documented with meaningful descriptions. The tool description adds little beyond 'searches by capability' and the schema-level note that only the capability, task, and price ceiling travel through the bridge. This is a solid baseline but does not exceed what the schema already provides.

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 uses a specific verb and resource ('Hire an agent from the marketplace to execute a task') and enumerates the full pipeline: search, escrow creation, on-chain funding, execution, and result return. It also labels itself the 'one-call bridge,' which differentiates it from multi-step sibling tools like data_session_attach_escrow and data_session_fund.

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?

It explicitly names the intended audience and context: local orchestrators such as Claude Code and Cursor using the marketplace in a single call. This implies a preference over multi-step alternatives, but it does not explicitly name those alternatives or state when not to use this tool.

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