group_delete

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

Discloses specific error behavior ('not-found error if the group does not exist') and success behavior ('Returns confirmation'), which compensates partially for missing annotations. However, lacks disclosure on destructive permanence, cascade effects on group memberships, or authorization requirements given the destructive nature and absence of destructiveHint annotation.

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?

Three sentences with no waste. Front-loaded with the core action, followed by precise behavioral outcomes. Every sentence earns its place by conveying distinct information (purpose, success case, error case).

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?

Covers basic operational contract (success/error) but insufficient for a destructive operation with no annotations. Missing critical safety context such as whether deletion is permanent, whether members are cascade-deleted or orphaned, and required permissions.

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?

Input schema has zero parameters, which normally warrants baseline 4. The description adds crucial context by specifying 'by ID', indicating the group identifier is required (likely as a path parameter not reflected in the body schema), though it does not specify the ID's data type or format.

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?

Clear specific verb ('Delete') + resource ('Operaton group') + scope ('by ID'). Distinguishes effectively from siblings like group_create, group_addMember, and group_list by specifying the destructive removal action on the entire group entity.

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?

Provides no guidance on when to use this tool versus alternatives like group_removeMember (which removes a user from a group without deleting the group itself). No prerequisites or conditional usage scenarios are mentioned.

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