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

With no annotations, the description carries the full burden. It only states 'READ-ONLY' to indicate no side effects, but does not disclose behavior on missing entries, response format, error handling, or any authorization requirements. For a read tool, this is minimally transparent.

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 two sentences, concise and front-loaded with the purpose. Every word contributes to understanding. No unnecessary details.

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 read tool with an output schema, the description is adequate but lacks explicit mention of preconditions (e.g., prefix-list must exist) or error behavior. It relies on the user knowing to obtain entry_id from a prior call. Could be more complete.

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 100%, so the baseline is 3. The tool description adds context about entry_id being opaque and contrasts with route-map's order, which provides slight additional meaning beyond the schema. However, this is not a major addition.

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 a single prefix-list entry', specifying the verb (read) and the resource (single entry). It also explains the opaque nature of entry_id, adding clarity. This effectively distinguishes from listing all entries, though not explicitly naming sibling 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?

No explicit guidance on when to use this tool versus alternatives like pve_sdn_prefix_list_entries_list. The description does not indicate prerequisite steps (e.g., need to list entries first to get entry_id) or when not to use it. The opaque token hint is useful but insufficient as usage guidance.

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