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

With no annotations, the description carries the full burden and does disclose important behavior: the seller-only authorization scope and, crucially, the consequence that the last delivery is evaluated and ruled release or refund. It omits reversibility and any timing/permission detail beyond the role, but the outcome disclosure is substantive.

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 tight sentences, front-loaded with the role constraint and purpose, then the consequence. No filler and 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 mutation tool with no annotations and no output schema, the definition covers role, triggering condition, and the resulting evaluation outcome, which is what an agent most needs to call it correctly. It leaves the mechanics of the release/refund ruling unexplained, but that is largely outside the tool's invocation contract.

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 both parameters are already documented (reason = why the delivery meets the description; escrowId). The description restates the same rationale concept rather than adding format or syntax detail beyond the schema, so the baseline 3 applies.

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?

States a specific verb (decline) and resource (a pending revision request), plus a role scope (Seller only) and the operative condition (delivery already meets the escrow description). This clearly distinguishes it from the related request_revision and release_escrow siblings by role and intent, though it does not name any sibling explicitly.

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?

Gives clear context for use: seller-side, and specifically when the delivery already satisfies the description. It does not state when-not to use it or point to an alternative (e.g., raise_dispute), so it stops short of full routing guidance.

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