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

No annotations are provided, so the description carries the full burden. It discloses ordering ('newest first') and returned fields (id, paper or idea, verdict, report hash), which helps an agent know what it will get. It does not state that this is read-only, whether there is a result cap, or how many crossings are returned, which are important for a zero-parameter listing 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?

One compact sentence, front-loaded with the resource and ordering, and the returned columns are listed efficiently. Nothing is wasted.

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 listing with no output schema, the description gives the scope, ordering, and field names, which is nearly enough to call it correctly. Missing only a note on volume or caps and an explicit safe/read-only statement.

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?

There are 0 parameters, so the baseline is 4. The description correctly does not invent parameters and instead describes outputs. It could explicitly say 'no parameters – returns all crossings', but the omission is minor.

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?

States a specific verb and resource ('Every crossing this server ran') and the ordering ('newest first'), plus enumerates returned fields. Clear enough to distinguish from knos_cross (which presumably creates a crossing) and from other knos_* memory 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?

The phrase 'this server' implies a server-scoped listing, but there is no explicit when-to-use guidance, no mention of limits or pagination, and no exclusions or alternatives such as knos_memory_search. Usage is only weakly implied by the name and description.

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