poa_epochs

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no read/write indication, no pagination, no rate limits, no return shape. The only added fact is the REST path, which does not describe 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?

It is a single noun fragment with no bloat, but the brevity is under-specification rather than economy. There is no verb and no front-loaded statement of what the call does.

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 no-arg, no-annotation, no-output-schema tool the bar is low, yet the description still omits the operation and any hint of what records are returned. An agent cannot confidently decide to invoke it over the other epoch-related siblings.

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 tool takes zero parameters, so there is nothing for the description to explain beyond what the empty schema already conveys. Baseline 4 applies for a no-argument tool.

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 names the resource ('Epoch close records') and pins it to an endpoint (/api/epochs), which is more than the bare tool name provides. However, it supplies no verb, so an agent cannot tell whether this lists, fetches, or summarizes epoch records, and nothing distinguishes it from siblings like poa_ballots or poa_params.

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?

There is no guidance on when to call this versus the many sibling query tools (poa_status, poa_params, poa_explorer, etc.). The agent is left to infer usage entirely from the name.

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