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

No annotations are provided, so the description carries the full burden. It discloses the need for API key authentication and that the action 'commits virtual funds,' signaling mutation and risk. It could add details on irreversibility or post-bet effects, but it already provides meaningful behavioral context beyond the schema.

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, each with a distinct purpose: state the function, note the authentication requirement, and issue a caution. No filler or redundancy, well-front-loaded.

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 simple mutating tool with no output schema, the description covers the essential aspects: purpose, prerequisite, and risk. It does not describe post-bet behavior or confirmations, but that is not required given the schema and context. Overall adequate and complete enough for an agent to invoke 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?

The description does not elaborate on any parameters, but schema coverage is 100% (every field has a description). Since the schema fully documents parameters, the description adds no additional meaning—baseline 3 is appropriate.

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?

Clear verb 'Place' and resource 'bet on prediction market' directly state the function. It is distinct from sibling tools, which are all read-only getters (get_leaderboard, get_markets, etc.).

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?

The description mentions a prerequisite (API key) and a caution ('Use with caution'), but it does not explicitly say when to use this tool versus alternatives or when not to use it. The intended usage is implied by the name and the read-only nature of siblings.

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