Create an environment

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

With no annotations, the description carries the full behavioral burden and does a good job: it discloses that the operation mutates a live environment, defaults to a dry run without confirm, consumes tenant capacity, and runs 'pac admin create' under the active pac auth profile. It stops short of a 5 because it does not state required admin permissions or other tenant-level prerequisites beyond capacity.

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 core purpose. It loses a point for redundancy: the phrase 'requires confirm: true' appears twice, once with capacity and once with live mutation, which could have been consolidated.

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?

For a high-complexity admin mutation with 23 parameters and no output schema, the description covers the essential agent-facing context: what it creates, that it is live and destructive with a dry-run default, that it consumes capacity, and what underlying command it runs. The schema covers the parameter details, and no return value explanation is needed, though the description could be slightly more complete by noting admin authorization requirements.

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% across 23 parameters, so the schema already carries the parameter semantics. The description mentions confirm and the active pac auth profile, but this largely repeats what the schema's confirm and profile descriptions already state, adding no new syntax or meaning.

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 and resource: create a Dataverse environment in the tenant. It is clearly distinct from list/delete/copy/reset siblings by verb, but it does not explicitly name or differentiate against the nearest alternative, cs_admin_copy_environment, so it falls short of a full 5.

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?

The description implies usage (create a tenant environment) and supplies two important preconditions: it consumes tenant capacity and requires confirm: true, otherwise returning a dry run. However, it gives no explicit when-not-to-use guidance and does not route the agent to alternatives such as cs_admin_copy_environment or cs_admin_list_environments.

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