propose_a2a_trade_deal

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

No annotations are provided, so the description carries the full disclosure burden. For a state-mutating, contract-creating tool it says nothing about side effects (does a proposal persist? notify the buyer? lock terms?), whether the proposal is binding or reversible, or what signature/permission requirements apply. 'Proposes' implies non-finality but this is never confirmed.

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 with the actor, action, object and signature requirement front-loaded and no filler. Slight cost: the compression leaves out lifecycle detail rather than being wasteful.

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?

Complex domain (bilateral trade agreement, cryptographic signing, nested spec with FEOC and mass-balance flags) with no annotations and no output schema. The description omits the proposal lifecycle, what counterparty action follows (dual signature), and what the caller gets back, leaving the agent under-informed for a consequential operation.

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%, and the nested TradeDealSpec properties each carry their own descriptions and examples, so the schema already does the heavy lifting. The description adds no semantics beyond the schema (e.g. format or provenance of seller_signature over the deal hash). Baseline 3 is appropriate.

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 and resource: a seller agent 'proposes a canonical bilateral trade agreement' for a critical mineral consignment, with a cryptographic signature. This is distinguishable from siblings like dual_sign_trade_deal and verify_a2a_trade_deal, though it never names them or states the relationship 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?

No indication of when to call this versus dual_sign_trade_deal, verify_a2a_trade_deal, or reject/cancel_a2a_trade_deal. The agent is left to infer that this is the initiating step of a bilateral flow, and nothing states prerequisites such as an open agent session or a verified EBL.

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