arena_reveal_seed

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

No annotations are present, so the description carries the burden. It discloses the auth requirement and timing, and explains the rationale for revealing. However, it does not mention side effects of rotation (e.g., impact on client seed or irreversibility), which would be relevant for a mutation 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 concise sentences that front-load the action and purpose, then add timing and requirement. No wasted words.

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 zero-parameter tool with no output schema, the description covers what, why, when, and the auth requirement. Minor gap: does not explain what happens to the client seed or whether the rotation is reversible, but this is not critical for a simple seed reveal/rotate operation.

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?

Tool has zero parameters, so there is no parameter semantics to add. The baseline for 0-param tools is 4, and the description correctly avoids redundant parameter info.

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?

Description clearly states the tool reveals the current server seed and rotates to a fresh one, with a specific purpose (verification against committed hash). It distinguishes from siblings like arena_set_client_seed by explicitly mentioning 'server seed' and 'rotate'.

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?

Provides explicit timing guidance ('Do this after an event, not mid-entry') and a hard requirement (AGENT KEY). Does not name alternatives, but the context makes the use case clear.

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