A3.8/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It only says 'set' and lists allowed values; it does not disclose side effects, overwrite behavior, permissions, persistence, or any response/confirmation behavior for this mutating tool.

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 short sentences, zero filler. The action is front-loaded and the value guidance immediately follows, making the description easy to parse and act on.

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

Completeness3/5

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

For a single-parameter setter, the description is mostly adequate and covers the key input semantics. However, with no annotations and no output schema, it omits behavioral context such as whether the change is immediate, persistent, or scoped to a specific workspace, leaving an agent with some uncertainty about consequences.

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

Parameters5/5

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

The input schema description coverage is 0%, but the description fully compensates by explaining the single domain_schema parameter: null for General Engine, 'edtech' for EdTech, and 'support' for Customer Support. This adds meaning the schema's bare anyOf does not provide.

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?

The description uses a specific verb ('Set') and resource ('workspace domain schema'), and clearly distinguishes itself from the sibling getter memoryos_get_domain_schema. The allowed values further specify what the tool does, making its purpose unambiguous.

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

Usage Guidelines3/5

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

The first sentence states the operation, and the value mapping implies when you would use it. However, it does not explicitly guide an agent away from related tools such as memoryos_set_support_type or explain when to read instead with memoryos_get_domain_schema.

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