sigma_bulk_assign_team_members

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

Annotations already indicate a non-read-only, non-destructive operation. The description adds that the operation is batched ('in one call') but does not disclose other behavioral traits such as handling of duplicate memberships or atomicity.

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 a single sentence with no wasted words, clearly stating the action and scope. It is appropriately sized for a simple tool.

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?

Given the simple two-parameter schema and presence of an output schema, the description is largely complete. It covers the batch aspect ('in one call') but could benefit from mentioning error scenarios or idempotency. Still, it is adequate for typical use.

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?

With 0% schema description coverage, the description minimally compensates by using 'members' and 'team' to imply team_id and member_ids. However, it adds no deeper semantics beyond the schema's names and types, such as ID formats or edge-case behavior.

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 uses a specific verb 'Add', a clear resource ('multiple members to a team'), and a scope ('in one call'). This effectively distinguishes it from siblings like sigma_list_team_members (read) and sigma_update_team_members (update vs. add).

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 provides no guidance on when to use this tool over alternatives, nor does it mention prerequisites or scenarios (e.g., bulk add vs. incremental updates). Sibling tools are not referenced.

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