list_testflight_groups

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

No annotations provided. The description indicates a read-only list operation but does not disclose details like pagination, ordering, or authentication requirements. For a simple list tool, this is minimally adequate.

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?

Two sentences, zero redundancy. The first sentence states the action and resource, the second provides immediate utility context. No wasted words.

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 single-parameter list tool with no output schema, the description is complete: it tells what it does and how to use the results. Could mention if listing includes all groups regardless of status, but not essential.

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 100% with app_id described as 'The App Store Connect app ID'. The description adds minimal extra meaning by saying 'for an app', slightly reinforcing the parameter's purpose. Baseline score is appropriate.

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 clearly states the verb 'List' and resource 'TestFlight beta groups for an app'. It distinguishes from sibling tools like create_testflight_group (creates groups) and upload_to_testflight (uses groups) by explicitly stating the output usage.

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 explicit usage context: 'Use a group name from this list in the beta_group parameter of upload_to_testflight'. While it lacks when-not-to-use, the guidance is clear and practical for the tool's purpose.

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