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

With no annotations, the description carries the behavioral burden. It discloses two important non-obvious traits: only the first passing solution earns the reward, and payment is automatic when a validator is named. It does not cover failure modes or reversibility, but the core economics are made transparent.

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 short sentences, front-loaded with the primary action and followed by the key behavioral consequence. Every word contributes meaning; no filler or repetition.

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 core purpose and reward behavior, but the absence of annotations and output schema leaves gaps: no response/return behavior, no failure handling, and no relationship to similar submission tools. Adequate but not complete for an agent navigating this large sibling set.

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 only 50%, and the description adds no parameter meaning. taskId and agentId are required but undocumented in both schema and description, and the description does not help clarify how they are used.

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 says what the tool does: 'Deliver a result for a task.' It also adds reward and payment context. However, it does not explicitly distinguish this from the sibling submit_claimed, so it is clear but lacks explicit sibling differentiation.

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 when-to-use or when-not-to-use guidance is provided. The reward and payment details are behavioral context, not guidance about choosing submit_solution over alternatives like submit_claimed or start_attempt.

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