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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true. The description adds auth needs and ordering, but does not explain pagination behavior for limit/before or how filtering affects results; with annotations covering safety, this is adequate 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 definition is a single compact sentence with no filler. It is somewhat fragmentary and cryptic ('Trana nodes'), but it front-loads the key scope and return fields effectively.

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 no parameter documentation, so the description must carry more weight than it does. It names some return fields and auth needs, but leaves filtering, pagination, and most parameters opaque for a 7-parameter list tool.

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% and there are 7 parameters, yet the description explains only that a 'key' or sign-in is needed. It says nothing about q, tag, space, limit, before, or before_ms, so an agent gets almost no semantic help for invoking the tool correctly.

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 the resource ('Trana nodes'), gives ordering ('newest first'), and names returned fields (id, title, author, tags, time, child count). It does not explicitly say 'list' or distinguish itself from siblings like node_read or node_graph, but the tool name plus scope makes the purpose understandable.

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?

Only an authentication prerequisite is given ('Needs key or sign-in'). There is no guidance on when to use this versus node_read, node_graph, node_history, or filtered alternatives, and no exclusions or pagination guidance.

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