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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so the safety profile is covered. The description adds some behavioral context about merging owner nodes and company branches and reading with a version vector, but the version-vector sentence is cryptic and does not fully explain the behavior.

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 and front-loads the main read operation. The second sentence is relevant but awkward and unclear, slightly reducing structural quality without adding unnecessary length.

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?

Although output schema and annotations are present, the input is complex with nested objects and only 33% schema description coverage. The description leaves important gaps around when to use this versus schema_resolve_schema and what the nested taxonomy/companyId/versionVector inputs mean.

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 only 33%, and the description does not compensate by explaining the nested taxonomy, companyId, or versionVector parameters. It mentions 'version vector' but does not clarify its format, role, or how it changes the result.

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?

It states a specific verb and resource ('Read a taxonomy as one tree') and adds the composition ('owner's nodes with the company's branches, each with its owner and depth'). The purpose is clear enough to distinguish a read operation, but it does not explicitly differentiate this from the sibling schema_resolve_schema.

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?

There is no explicit guidance on when to use this tool versus alternatives such as schema_resolve_schema. The mention of a version vector implies one usage mode but does not state when or when not to use it.

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