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

No annotations, so the description carries full burden; it does earn credit for disclosing that the claim is 'unsigned' (i.e., a transaction payload rather than a broadcast action). But it never says whether anything is submitted, what signing/submission step follows, or what permissions/balance conditions gate the claim.

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 front-loaded sentence with no filler, and the two valid claim sources lead the description. Slightly terse given the jargon ('Convoy hit', 'Ledger job') is unexplained.

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?

With no annotations and no output schema, the description should state that the return value is an unsigned transaction payload the caller must sign and submit. That return-shape gap leaves the definition adequate but incomplete for a tool whose entire purpose is producing a signable artifact.

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 wallet field already explains that nothing is sent from it and it is used for balance/allowance reads and simulation. The description adds no further meaning to either the wallet or the game enum parameter, so 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 specific verb ('prepare') and resource ('unsigned claim of your winnings') scoped to two game modes, convoy and ledger. An agent can distinguish it from the many sibling prepare_*_claim tools (raid, night_run, vehicle_heist) because the two supported claim sources are 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 by 'your winnings' – the agent must infer the tool is called after a convoy hit or ledger job has completed and produced a payout. No prerequisites, no when-not-to-use, and no pointer to the sibling claim tools that would otherwise look similar.

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