Create organization

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

Annotations only cover the generic safety profile (readOnly=false, destructive=false, idempotent=false); the description goes well beyond that with atomicity of org plus default resources, replay semantics tied to an idempotency key, and the fact that optional provider provisioning happens post-commit, retries asynchronously, and never fails organization creation. That last point is exactly the kind of partial-failure behavior an agent could not infer from the schema or hints.

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?

Four tight sentences, front-loaded with the core action and its atomic scope, then escalating to replay semantics and finally deferred async provisioning. Every sentence conveys a distinct operational fact; nothing is restated from the title, annotations, or schema.

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?

With no output schema, the description carries the return-value burden and partially discharges it by stating that a replay returns the existing organization, but it never describes the shape of a first-time response (e.g., the new organization ID), which an agent needs to chain follow-up calls. Combined with the unaddressable idempotency-key mention, one small gap remains, but behavior for a single-parameter mutation tool is otherwise well covered.

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 100% for the single 'name' parameter, so the baseline is 3 and the description adds no name-level semantics (length, normalization, allowed characters) beyond what the schema states. It also references an 'idempotency key' that does not appear anywhere in the input schema and which additionalProperties:false forbids, so the mention adds ambiguity rather than parameter clarity.

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?

The description opens with a concrete verb+resource ('Creates the organization') and adds scope ('and its local default resources atomically'), so an agent immediately knows this is the org-creation entry point. It never names or contrasts a sibling, but none of the listed siblings is a competing org-creation tool, so the risk of misselection is low.

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?

Usage is implied by the verb, and the idempotency-key paragraph implicitly tells the agent when to supply a key (retry/replay safety) versus not ('without a key, each request is a fresh attempt'). However, there is no explicit when-to-use/when-not framing, no prerequisite or permission guidance, and no reference to alternatives such as orgs_list for verifying an existing organization.

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