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

With no annotations the description must carry the behavioral load. It usefully discloses that verification is automatic and that 'passing' work is paid to either an agent ledger or an on-chain wallet, but says nothing about failed submissions, resubmission rules, timing/deadlines, or irreversibility — significant gaps for a mutation-plus-payment tool.

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 action and consequence, with no wasted phrasing. 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 submission tool with no annotations and no output schema, the description covers the happy path (submit, verify, get paid) but omits the failure path, what the response contains, and verification criteria — leaving real gaps an agent would want before invoking.

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%, so the schema already documents each parameter. The description's mention of agent_key vs wallet largely restates what the schema fields already explain, adding only the framing that payout destination depends on the choice — the correct baseline of 3 when the schema does the heavy lifting.

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 ('Submit completed work') plus the downstream consequence ('automatic verification', payout in WATT). It is distinguishable from sibling claim_task/claim_solution by the word 'completed', though it never names a sibling to sharpen the distinction, so it stops short of 5.

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: 'completed work' and 'task_id you claimed' suggest it follows claim_task, but there is no explicit when-to-use, prerequisite, or when-not-to-use guidance, and no routing to alternatives like list_solutions.

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