sandbox_testers_v2_get_collection

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not pagination behavior (despite a limit parameter), not the fact that this is a read-only operation, not response shape, not auth requirements. A bare path echoes no behavioral traits.

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 this is under-specification rather than conciseness: a duplicated route string is the entire content, with no front-loaded purpose sentence for an agent to anchor on.

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?

With no annotations and no output schema, the description must supply the missing context for a paginated collection read, but it supplies none. The schema documents inputs only, leaving return shape, pagination semantics, and scope unexplained.

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%, with both limit ("maximum resources per page") and fields_sandboxTesters (sparse-fieldset selection) fully documented in the schema, including the enum of selectable fields. Per the rubric, high coverage sets a baseline of 3; the description adds nothing beyond it.

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 is just the HTTP route restated twice: "GET /v2/sandboxTesters (GET /v2/sandboxTesters)". It conveys that this is a collection read of sandbox testers, but it is essentially a tautology of the tool name and adds no natural-language statement of what the resource represents or what it returns.

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 whatsoever on when to use this versus siblings such as sandbox_testers_v2_update_instance, or versus other tester-collection endpoints (beta_testers_get_collection). Nothing distinguishes the sandbox tester population from beta testers or explains prerequisites.

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