verify_a2a_trade_deal

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

With no annotations, the description must carry the behavioral burden, and it does disclose the concrete verification dimensions (three signatures plus FEOC and mass-balance checks). However it says nothing about read-only vs state-mutating behavior, required authorization, or failure/error semantics for an audit operation.

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?

A single dense sentence that front-loads the action and resource before the enumeration of checks. Nothing is wasted, though there is no structural separation between the core action and the list of verified properties.

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?

No output schema and no annotations exist, so the description should ideally indicate what an audit returns (e.g., per-signature pass/fail or compliance verdict). It names the checks but not the result shape, leaving an agent guessing about the response.

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 coverage is 100% for the single deal_id parameter, which the schema already documents as 'Trade deal identifier to audit'. The description adds no format, provenance, or identifier-scheme detail beyond that, 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 precise verb ('cryptographically audits') and resource ('dual-signed A2A trade deal'), and enumerates the specific checks (seller/buyer/oracle signatures, FEOC and mass-balance compliance). This makes it clearly distinct from the signing/proposing/cancelling siblings, though no sibling is named 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?

Usage is only implied: an agent can infer this is the audit step for an existing deal, presumably after dual_sign_trade_deal. There is no explicit when-to-use, prerequisite, or guidance on alternatives such as get_a2a_trade_deal or verify_mineral_lot_compliance.

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