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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explicitly states the financial split (amount−fee to worker, fee to Guild), the reputation impact, and the authentication requirement (payer's api_key). It also mentions the return type (settlement detail). This is thorough and leaves no major behavioral trait undisclosed.

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?

Two concise sentences plus a compact example. Every sentence adds meaningful information: what happens, who authenticates, what is returned, and how to call it. No filler or redundancy; the structure is front-loaded and easy to parse.

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 description is generally thorough, covering the settlement flow, authentication, and return. However, the rating parameter's role, range, or effect on settlement is not explicitly defined; only an example value is given. This minor gap prevents a perfect completeness score but does not materially impair an agent's ability to use the 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 0%, so the description must compensate. It successfully explains issuer_api_key (payer's key), escrow_id (the escrow identifier), and deliverable (the work product) via the example. Rating is only shown in the example without explicit meaning, but the example provides a concrete value and context implies it's a quality rating. This adds significant value beyond the bare schema.

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 opens with 'Accept delivered work and settle the escrow' – a specific verb+resource that clearly identifies the tool's function. It distinguishes itself from siblings like guild_escrow_open by detailing the settlement outcome (worker paid, Guild fee, transaction recorded), leaving no ambiguity.

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 establishes clear usage context: it is for settling escrow after work has been delivered, and it explicitly states that the caller must authenticate with the payer's api_key. It does not name alternatives or exclusions, but the context is sufficient for an agent to infer when to use this tool versus others.

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