Check for Paperless updates

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

Annotations already establish this as read-only, idempotent, open-world, and non-destructive. The description adds that the tool reports the latest release and update availability, but it does not disclose whether this involves a network call, how failures are handled, or the exact shape of the response. With strong annotation coverage, this is acceptable but not rich.

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 very short and free of filler, but it is a sentence fragment rather than a complete, front-loaded statement of action. It conveys the key information efficiently, though a verb would improve its structural quality.

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 zero-parameter, read-only tool with strong annotations, the description covers the essential outcome: the latest release and whether an update is available. There is no output schema, so a bit more detail about the return format would be helpful, but an agent can still select and invoke this tool correctly with the information provided.

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 has zero parameters, so the schema already covers everything needed for invocation. The description adds semantic context about what the result represents, which is useful, but parameter-related information is inherently complete due to the empty schema.

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 title 'Check for Paperless updates' supplies the missing verb, and the description names the resource: the latest Paperless-ngx release plus update availability. This is distinct enough from siblings like get_server_status or get_statistics, though the description itself is a noun phrase rather than an explicit action statement.

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 title implies the use case: checking for Paperless updates. However, the description gives no explicit when-to-use guidance, no mention of alternatives, and no context about how this relates to other status/statistics tools. The usage context is only implied, not stated.

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