TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds real behavioral value by disclosing what the call returns (available node spaces, the active one, the alias table) and that addressability is build/material dependent. It does not cover error behavior or output shape, keeping it below 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the return content, followed by the usage directive. No filler or restatement of the name/title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only, single-parameter introspection tool with no output schema, the description covers what is returned and the prerequisite use case. It stops short of describing the alias table's structure or the failure mode when a node_space is not addressable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% ('Material handle.'), so the schema already documents the sole parameter. The description adds no further detail about the handle's accepted forms (object/material/tag/etc.), so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (report) and precise resource (node spaces a material exposes, the active one, and the alias table). It is clearly distinguishable from siblings like list_graph_nodes (which enumerates nodes) and apply_graph_description (which mutates).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly names the ordering relationship and alternative: 'Use this before `apply_graph_description` to confirm the right `node_space` is addressable.' The agent knows exactly when to call this tool relative to its sibling.

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