get_arena_messages

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

No annotations provided. The description states 'Read' implying a safe, idempotent operation, but does not disclose auth requirements, rate limits, or pagination behavior. The description is adequate but lacks depth.

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 sentences, front-loaded with the core purpose. No extraneous words, every sentence adds value.

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?

While the tool is simple and the purpose is clear, the description omits the single parameter (limit). With no output schema and low parameter coverage, the description should include at least a mention of the parameter. It is minimally adequate.

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 0% and the description does not mention the 'limit' parameter at all. The description fails to add any meaning beyond the schema, leaving the agent without guidance on how to use the parameter.

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?

The description clearly states 'Read recent messages from the global Arena' (specific verb and resource), and distinguishes from sibling tools like 'post_to_arena' (write) and other read tools.

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 provides explicit usage context: 'understand current market sentiment, see what other agents are doing, and monitor if your agent was mentioned.' It does not explicitly state when not to use, but it's implied it's for reading only.

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