app_store_version_phased_releases__create

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

Annotations are all false, so the description carries the burden. It reveals key behavior (gradual rollout over 7 days), which goes beyond the annotations. However, it does not mention idempotency, potential failures, or the response structure.

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 a single sentence with the endpoint appended. It is front-loaded with the core action and contains no superfluous information.

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?

The description mentions the key context (approved version, 7-day rollout) but omits what the response contains and does not explicitly state that the version must be in an approved state. Minor gaps for a creation tool without an output schema.

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 description needs minimal parameter details. It does not explain the body structure or the 'phasedReleaseState' attribute, but the schema already defines these. The description adds no extra semantic beyond what the schema provides.

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 action ('start'), the resource ('phased rollout'), and the scope ('for an approved version') with a specific timeframe ('over 7 days'). It distinguishes the tool from sibling tools like 'update' and 'delete' by focusing on creation.

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?

It indicates the prerequisite of an 'approved version,' but does not explicitly exclude usage when a phased release already exists or when to use the update tool instead. The context is clear but lacks explicit alternative guidance.

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