Preview: Create an entity

preview_create_entity

Read-onlyIdempotent

Prepare creating a workspace entity with the supplied name. Requires settings permission and confirmation. This returns an exact preview and a five-minute confirmation token; it does not apply the change.

Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the description only needs to add beyond that. It does: the required permission, the confirmation requirement, the five-minute token lifetime and the guarantee that no change is applied — useful behavior an agent cannot see in 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.

Conciseness5/5

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

Two tight sentences; the non-mutation guarantee is front-loaded immediately after the purpose so an agent can decide fast. No filler.

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?

With no output schema, the description correctly compensates by stating what is returned (an exact preview plus a five-minute confirmation token). Only minor gaps remain around what the preview payload contains and what the token is passed to.

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

Parameters2/5

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

Schema description coverage is 0% and the description only echoes that a 'name' is supplied, without stating its meaning, format, or the 1-255 length constraint enforced in the schema. For the sole input parameter this leaves the semantic burden unmet.

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

Purpose4/5

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

States a specific verb and resource: prepares (previews) the creation of a workspace entity from a supplied name. The clause 'it does not apply the change' cleanly separates it from the mutating create_entity sibling, though it never names that sibling explicitly.

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

Usage Guidelines4/5

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

'Requires settings permission and confirmation' plus the confirmation-token mechanism clearly signals this is a permission-gated, two-step workflow. No explicit 'then call create_entity to apply' routing, so it is not a 5.

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