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

Annotations already establish that this is a safe, idempotent, non-destructive read. The description adds useful context by stating the authentication requirement and listing returned fields, but it does not explain pagination behavior despite having after and limit parameters.

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 short but appears truncated and structurally incomplete, with an unfinished parenthetical and ellipsis. It front-loads the resource but does not deliver a complete, readable statement.

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?

There is no output schema, and although the description lists some return fields, it leaves key call semantics unclear: after/limit behavior, child-node pagination, and the exact meaning of id are not covered. For a four-parameter read tool with 0% schema coverage, this is incomplete.

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 0%, so the description must carry parameter meaning. It only hints at the key/sign-in requirement and does not explain the required id, the after cursor, or the limit 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 identifies a specific resource, a single Trana node, and enumerates what is returned: title, text, author, tags, and child nodes. It is clear enough to distinguish a single-node read from generic operations, though it does not explicitly name sibling alternatives such as node_list or node_graph.

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 only usage-oriented note is 'Needs key or sign-in,' which covers authentication but not when to choose this tool over node_list, node_graph, or node_history. No exclusions or alternative-selection guidance is provided.

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