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

No annotations are supplied, so the description carries the full behavioral burden. The word 'List' implies a read, but the text never explicitly states that the operation is read-only, requires no auth scope, or has no side effects; it also says nothing about caching or freshness of the schema.

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 the resource first and the returned categories enumerated as a compact list. Every word earns its place, with no preamble or filler.

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?

An output schema exists, so return-value details are covered elsewhere, and with zero parameters the call surface is trivial. The description lists what categories the schema contains, which is enough for an agent to invoke it correctly; only the read-only/when-to-use framing is missing.

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?

The tool takes zero parameters with a closed schema (additionalProperties false), so there is nothing to disambiguate and the baseline of 4 applies. No parameter-level meaning needs to be added by the description.

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 ('List') and resource ('org ontology schema') and enumerates the four schema components returned (link types, object kinds, interfaces, action types). This separates it from the sibling setters such as memory_ontology_link_type_set and memory_ontology_object_kind_set, though it does not explicitly distinguish itself from read-side siblings like memory_ontology_kind_stats or memory_tools_catalog.

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 guidance on when to call this versus alternatives. The description never mentions that sibling setters (e.g. memory_ontology_link_type_set, memory_ontology_object_kind_set) mutate the very schema this tool reads, nor are prerequisites or typical call contexts described.

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