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

Annotations already declare readOnlyHint and openWorldHint, so the description adds modest value by stating 'newest first' and 'full public record'. However, it does not disclose behavior around the limit parameter, such as default count, upper bounds, or pagination behavior.

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?

The description is a single, concise sentence that leads with the core purpose ('The bulletin archive') and includes ordering information. There is no redundancy or unnecessary detail.

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?

The tool has a simple signature with one optional parameter and no output schema, so the description is fairly complete regarding return values. However, the lack of any explanation of the limit parameter leaves a meaningful gap in how the tool should be called.

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 input schema has a single 'limit' integer parameter with 0% schema coverage, and the description does not mention or explain this parameter at all. Since description coverage is low, the description was expected to compensate but fails to add any meaning to 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 identifies the tool as an archive of bulletins and indicates a list operation with 'full public record' and ordering 'newest first'. It effectively distinguishes from the sibling get_bulletin by implying list versus single-item retrieval.

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 explicit guidance on when to use this tool instead of alternatives like get_bulletin, nor does it mention how the limit parameter might be used. Usage is only vaguely implied by the nature of the resource.

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