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

With no annotations, the description carries the full burden and does disclose the crucial trait: the tool returns an unsigned transaction that the caller must sign and broadcast, and it will fail outside the settled/won/voided conditions. It does not state what happens on an ineligible call (revert vs error payload) or whether repeated calls are safe, so it is strong but not complete.

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?

Three short sentences with the namespace prefix, the action, the eligibility constraint, and the signing handoff front-loaded. Nothing is padded or repeated.

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?

There is no output schema, and the description covers the one thing the caller most needs to know about the return value (an unsigned tx you sign yourself) plus the eligibility gate. Remaining gaps are edge-case error behavior rather than anything needed to invoke it correctly.

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 0% and the description says nothing about 'wallet' or 'fightId'. The names and types are largely self-explanatory, and 'for one fight' ties to fightId, but no format, address-vs-identity, or which-fight-selection guidance is added.

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 an unsigned claim transaction) and resource (fight winnings for one fight), and the parenthetical '(claim)' resolves it against the many other 'prepare_*' siblings. An agent can tell it apart from prepare_fight_settle, prepare_fight_boost, and my_fight_winnings without opening a schema.

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?

Explicit preconditions are given: 'Only after the fight is settled and only if you bet on the winner or it was voided.' It also clarifies the two-step handoff ('You sign and send it yourself'). It does not point to a sibling such as my_fight_winnings for checking eligibility, so it stops short of naming alternatives.

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