bale_invite_to_group

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

No annotations are provided, so the description carries the full burden. It does not state permission requirements, what happens if a user is already a member, whether invitations notify users, or whether the operation is reversible. 'Existing group' hints that the group must pre-exist but nothing more.

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?

A single front-loaded sentence with no filler. It is efficient, though the brevity is partly the cause of the missing detail noted elsewhere.

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 mutation tool with no annotations and 0% parameter coverage, the definition is thin. An output schema exists so return values need not be described, but permission requirements, duplicate-member behavior, and parameter meaning are all absent.

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 coverage is 0%, so the description must compensate for both parameters. 'One or more users' usefully signals that user_ids accepts a batch, but group_id and the integer ID format are left entirely unexplained. This is far short of what a 0%-coverage, two-parameter tool needs.

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 gives a specific verb (Invite) and resource (users to an existing group or channel), and the word 'existing' implicitly separates it from bale_create_group. It is clear what the tool does, though it never names a sibling for contrast.

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?

There is no guidance on when to use this versus alternatives such as bale_get_group_invite_url or bale_create_group, and no stated prerequisites (e.g., caller must be a group admin/member). The agent must infer all usage conditions.

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