external_squad_add_users_to_external_squad

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 reveals only that this is a POST bulk mutation via the raw HTTP line; it omits that the operation requires confirm:true (documented only in the schema), what the bulk action affects, whether it is reversible, and any permission requirements.

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?

It is short, but the content is largely raw scaffolding: the HTTP verb/path line and a 'Tags:' controller label are generated noise rather than useful front-loaded information. The one meaningful sentence is buried after the route string.

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 no output schema, the description is too thin: it neither repeats the confirm/preview behavior nor explains the effect on the target squad. It lacks the safety and scope context an agent needs before invoking a bulk write.

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 uuid and confirm parameters are already fully documented in the schema, and the description adds nothing beyond the path it repeats. Baseline 3 applies when the schema does the semantic work.

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 states a verb and resource ('Add all users to external squad'), which is clearer than a bare endpoint dump and does distinguish the external-squad family from internal-squad siblings by name. However, 'add all users' is ambiguous and arguably inconsistent with the tool name, which implies adding specific users; no user list exists in the schema, leaving it unclear what is actually being added.

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 external_squad_remove_users_from_external_squad or the internal-squad add tools, nor any prerequisites, idempotency notes, or mention of the required confirm flag. The only routing signal is the endpoint path.

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