upload_to_testflight

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

Annotations indicate readOnlyHint=false and destructiveHint=false, but the description adds no behavioral context beyond what is obvious (download and upload). It does not disclose network requirements, authentication needs, rate limits, or any potential side effects, leaving the agent without additional safety or expectation management.

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 two sentences, front-loaded with the primary function and ending with the optional distribution capability. Every part earns its place, with no fluff or redundancy.

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 tool's simplicity (3 parameters, no output schema, annotations present), the description covers the core workflow and optional step. It omits prerequisites like App Store Connect access or Codemagic API keys, but these are commonly understood for such a tool. Overall, it is sufficiently complete for an agent to understand the tool's role.

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%, so the schema already fully documents parameters. The description loosely reiterates the purpose of ipa_url and beta_group but adds no new constraints or format details. Baseline 3 is appropriate as the description does not fall short but also does not enhance the schema.

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 it downloads an IPA from Codemagic and uploads to TestFlight via App Store Connect, and optionally distributes to a beta group. It is specific about the resource (TestFlight) and action (upload), but does not explicitly distinguish it from siblings like upload_build_to_asc, which may handle similar uploads.

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 implies the tool is for uploading TestFlight builds from Codemagic artifacts and optionally distributing to beta groups. However, it provides no explicit guidance on when to use this tool versus alternatives (e.g., upload_build_to_asc or submit_beta_review), nor does it mention prerequisites or exclusions.

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