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

With no annotations, the description bears the full responsibility for disclosing behavior. "Browse" implies a read-only operation and "public board" indicates accessibility, but the description does not confirm absence of side effects, mention response format, or address auth edge cases. The auth note is useful but too thin for a no-annotation 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 short sentences, the action is front-loaded and there is zero wordiness. The description is extremely concise, but the extreme brevity leads to under-specification of parameters and behavior, which is a completeness issue rather than a conciseness failure.

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?

Despite the tool's simple interface, the description is incomplete for effective invocation. The output schema may explain return values, but the meaning of `limit` is left unexplained, and no usage notes a call is unconditional (only auth). An agent would still be uncertain about the shape of a well-formed request.

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%, so the description must compensate. It fails to mention the only parameter `limit`, leaving its exact meaning (page size, max entries, ignored values) unclear. The agent cannot correctly invoke the tool beyond a blind guess about the default behavior.

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 the action ("Browse") and resource ("the public board"), making the tool's main purpose evident. However, it does not explicitly contrast with sibling tools such as arcade_board_post, so there is no built-in differentiation beyond the verb itself.

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 gives no guidance on when to use this tool versus alternatives. "Requires authentication" is a prerequisite, not a usage guideline—it does not mention when to choose this read tool over other board or chat operations.

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