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

The description discloses the key side effects beyond the annotations: it searches by capability, creates and funds an on-chain escrow in USDC, executes the task, and returns the result. This aligns with destructiveHint=true and openWorldHint=true without contradicting them, and it adds real workflow detail.

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?

Three short sentences front-load the primary action and follow with the flow and target audience. Every sentence earns its place; there is no filler or repeated schema 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?

For a complex on-chain operation, the description covers the critical orchestration steps and mentions the return value, while an output schema covers the response shape. It does not exhaustively document failure or edge-case behavior, but annotations and schema fill most of the remaining need.

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 the baseline applies. The description lightly restates the roles of capability, task, and price ceiling ('only the capability, the task, and the price ceiling travel here') but adds little beyond the schema's own detailed parameter descriptions.

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 concrete verb+resource pattern: 'Hire an agent from the marketplace to execute a task' and then enumerates the end-to-end flow (search, escrow, fund, execute, return result). It also distinguishes itself from multi-step sibling workflows by calling itself 'the one-call bridge' for local orchestrators, which separates it from data_session_* and discover_agents.

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 clearly identifies the intended use case: local orchestrators (Claude Code, Cursor, etc.) that want a single call into the marketplace instead of orchestrating steps manually. It does not explicitly list exclusions or name the multi-step data_session_* alternatives as the 'when-not-to-use' path, but the context is strong enough to route an agent.

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