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

With no annotations, the description carries the full behavioral burden. It usefully reveals the async lifecycle (submit then poll get_submission_status) and the prerequisite of ownership, but does not disclose whether submission is idempotent, what error occurs if already submitted, whether it is reversible, or what permissions are needed. Some value added, clear gaps remain.

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?

Three short sentences, front-loaded with the action and scoped immediately by the sequencing guidance. No filler or redundancy; every sentence carries operational 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?

With no output schema or annotations, the description supplies the workflow context an agent needs (prerequisites, the publish_app overlap, and the polling follow-up). It stops short of describing submission preconditions or failure modes, but is otherwise adequate for a 2-param tool.

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% and both parameters (slug, api_key) are documented in the schema, so the schema does the heavy lifting. The description reinforces ownership ('an app you own') but adds no syntax or format detail beyond the schema, which is the expected baseline when coverage is complete.

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?

States a specific verb ('Send') and resource ('an app you own') to a specific destination ('review'). It also distinguishes itself from publish_app, which handles submission as part of its own flow, so an agent can route correctly without opening either schema.

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?

Explicitly says when to use it (after create_app, upload_media, or update_app_html), names the alternative that already submits (publish_app), and gives the follow-up step (poll get_submission_status). This covers when-to-use, when-not-to-use, and the next action.

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