release_escrow

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

With no annotations, the description carries the full burden and discloses key behavioral traits: buyer-only restriction, state change to complete, and the DEPLOYER_PRIVATE_KEY prerequisite. It stops short of detailing irreversibility or failure modes, which would elevate it further.

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 sentences, no waste, front-loaded with the primary action. Every clause 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 simple one-parameter financial tool with no output schema, the description covers the actor, effect, and a critical prerequisite. Missing return value details are acceptable given the simple scope, though failure outcomes are not addressed.

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?

The schema already fully documents deal_id as 'Deal ID to release' (100% coverage), so the description adds no new parameter meaning. Baseline 3 applies because the schema handles it.

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 clearly states a specific action ('Release escrowed funds to the seller') and resource ('escrowed funds'), and distinguishes from siblings like refund_escrow (refund) and dispute_escrow by noting it marks the deal as complete and is buyer-only.

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 provides clear context: who can call (only buyer), what it accomplishes (releases funds, marks complete), and a required environment variable. However, it does not explicitly contrast with alternative tools like refund_escrow or dispute_escrow, so it lacks explicit 'when/not' comparison.

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