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, so the safety profile is covered. The description adds traversal behavior by saying it returns the root plus everything `depth` hops out and constrains depth to 1-3. It does not explain filtering behavior via `q` or `types`, return shape, or limits, and it is truncated.

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 front-loaded and begins efficiently, but it trails off mid-sentence ('child...'), making it structurally incomplete. As presented it cannot be trusted as a finished definition.

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?

This is a graph-retrieval tool with four parameters and no output schema, so the description should explain the query parameter, edge-type filtering, traversal semantics, and ideally the return shape. It covers only part of `root` and `depth` and is truncated, leaving significant gaps for an agent to call it correctly.

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 explain all four parameters. It partially covers `root` and `depth` (including the 1-3 range) but says nothing about `q` or the `types` enum values such as relates, blocks, duplicates, etc. Two of four parameters remain undocumented.

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 says it returns the graph of Trana nodes around a root id out to `depth` hops, which conveys the core retrieval operation. However, it is generic about what a 'node graph' means and does not distinguish it from siblings such as thread_graph, node_read, or node_list. The sentence is also visibly truncated, leaving the purpose only partially stated.

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 'give a root id' implies how to invoke it but gives no guidance on when to use this tool versus thread_graph, node_list, node_read, or ontology_query. There are no exclusions, prerequisites, or alternative-selection hints.

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