Create Access Group

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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=true, so the mutation profile is covered. The description still adds a genuine precondition not carried by the annotations: the call mutates community state and requires confirm=true before it will act on a user-requested action. It does not explain what side effects occur on related groups or members, which keeps it short of a 5.

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?

Two short sentences with no filler, and the state-changing/confirm requirement is front-loaded. The first sentence is pure restatement of the title, which is the only wasted space.

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?

This is a destructive, non-idempotent, open-world mutation with five parameters, nested objects, no required fields and no output schema, yet the description omits the create-vs-attach distinction, the payload/payload_file exclusivity, and any sense of what is produced. The schema carries most of the burden, but the description is too thin for a tool of this complexity.

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 80%, so the schema already documents account, confirm, payload, access_group and payload_file. The description adds nothing beyond confirming the confirm=true gate, and does not address the mutual exclusion between payload_file and payload/body flags. 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 first sentence, 'Create Access Group', states an unambiguous verb+resource, but it is a verbatim restatement of the tool title and name, so it adds no information. It also gives no differentiation from close siblings such as add_to_access_group, update_access_group, or archive_access_group, which an agent must distinguish between.

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 only usage cue is 'for the user-requested action' attached to confirm=true, which gestures at a precondition but never states when to choose this tool over add_to_access_group or create_space_group. No alternatives, no exclusions, no prerequisites beyond the confirm flag.

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