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

The description goes far beyond the annotations: no fee, no gas, no money moves, the board reads balanceOf but never prices the token, one offer per wallet per packet with replacement semantics, and the 5-minute signing window. This is rich behavioral context with no contradiction to the annotations.

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?

Every major claim earns its place and the critical workflow facts are front-loaded, but the paragraph is long and has mild redundancy ('FREE', 'no fee, no gas', 'NO money moves'). Still, the density is justified for a multi-step financial tool.

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 covers return values (MESSAGE_TO_SIGN and BODY_JSON), signing method, the 5-minute expiry, replacement behavior, refusal conditions, and the next tool to call. Given the tool's complexity and the presence of an output schema, nothing essential is missing.

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% and the schema already explains the parameters well, including atomic amounts, chainId names, and the address-only wallet rule. The description mostly restates these, adding only conceptual color like 'NEVER prices the token' rather than new parameter-level details.

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 the action ('offer to pay this packet in a token'), the resource (a work packet), and the allowed chains. It also identifies itself as step 1 of a 2-step flow, distinguishing it from prepare_token_settlement and submit_token_offer.

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 explicitly says 'Before the work', names the follow-up step (submit_token_offer within 5 minutes), and the downstream settlement tool. It also lists refusal conditions (claimed, settled, expired, already funded), giving clear when-not-to-use guidance.

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