No annotations are provided, so the description carries the full behavioral burden. 'Scans and returns' implies a read, but nothing is said about traversal depth behavior, result size, performance cost on large hierarchies, or whether the walk is exhaustive.
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?
A single front-loaded sentence with no filler. It is efficient rather than padding, though its brevity is partly under-specification rather than discipline.
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?
Two undocumented parameters, no annotations, and no output schema. The description omits the depth-bounding behavior that governs the return payload, leaving an agent unable to predict what the tree will contain.
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 compensate. It gives partial meaning to 'root' as the traversal start, but says nothing about 'maxDepth' (or that maxDepth defaults to 2, which materially limits what the tree contains).
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 ('scans and returns') and resource ('hierarchy tree') with a starting scope ('starting at root path'). It is roughly distinguishable from search_game_tree, but the description never names or contrasts that sibling, so the differentiation is left to inference.
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?
No when-to-use guidance, no exclusions, no alternatives. Given search_game_tree and inspect_instance exist as siblings, an agent gets no help deciding between a full-tree scan and a targeted search.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
