Assign a group to an environment

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

With no annotations, the description carries the full burden and does disclose the key behavioral traits: it mutates a live environment, it is gated by confirm: true, it falls back to a dry run, and it runs 'pac admin assign-group' under the active pac auth profile. It stops short of stating required permissions or what happens on partial failure.

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 definition is short but wastes a sentence: 'Changes a live environment: requires confirm: true' and 'Mutates a live environment: requires confirm: true (a dry run otherwise)' convey the same fact twice. The opening purpose sentence is well front-loaded, but the duplication means not every sentence earns its place.

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 12-parameter mutation tool with no annotations and no output schema, the description covers the critical safety gate and execution mechanism, and the schema documents the remaining parameters fully. It omits what the dry run returns and how the background/timeout options interact, leaving a modest gap.

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%, so the schema already documents all 12 parameters including confirm, group, role, and teamType. The description only restates the confirm gate and references group/role/team generically, adding no syntax or format meaning beyond the schema; baseline 3 applies.

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 names a specific verb and resource: granting an Entra group a security role in an environment via a Dataverse team. That mechanism ('through a Dataverse team') distinguishes it from the sibling cs_admin_assign_user and from cs_admin_add_environment_to_group without requiring the agent to open the schema.

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?

It provides one important precondition (confirm: true is required to effect change, otherwise a dry run), which is genuine usage guidance. However, it never states when to choose this over cs_admin_assign_user, nor which environments/roles are valid targets, so usage is only implied.

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