square_observe_locations

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds that routing is restricted to the governed connector authority and that Spring verifies the effect must be read, which is useful. The approval_ref note about 'resuming a write' is confusing in a read-only tool, but it does not directly contradict the annotations.

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 compact and organized as a clear bullet list with no filler. The operation name and routing constraint are front-loaded, and each parameter gets a single line.

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?

Even with annotations and an output schema present, the description omits the core semantics of what observe_locations returns and what arguments it expects. An agent cannot determine how to construct the arguments JSON or when to prefer this tool over square_list_locations.

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 bullet list provides one-line meanings for all seven parameters, which is helpful. However, the core 'arguments' parameter is only described as a JSON string for the connector operation, leaving the actual Square location-observation payload unspecified.

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 only restates the tool name as 'Square connector operation observe_locations' and never states what observing locations does (e.g., list/read Square locations). It adds a routing constraint but no verb+resource explanation, and it does not distinguish itself from the sibling square_list_locations.

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?

No guidance is given for when to use this tool versus alternatives such as square_list_locations or square_get_inventory. The only contextual note, 'Routes only through the exact project/account governed connector authority,' is a constraint, not a usage directive.

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