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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that reading is scoped to an existing edit, but says nothing about pagination, ordering, behavior on an empty or invalidated edit, or what the returned bundle/version-code structure looks like — a real gap given there is no output schema.

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?

A single front-loaded sentence with zero filler; the resource and scope come first. It is efficient but so terse that brevity comes at the cost of the missing guidance noted elsewhere.

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 tool with two fully undocumented required parameters and no output schema, the definition leaves the agent guessing at the shape of packageName/editId and at what the returned bundles and version codes contain. The annotations cover safety but not the operational detail the description should supply.

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 0%, so neither packageName nor editId is documented anywhere. The description hints that editId refers to an 'existing app edit' but adds no meaning for packageName, no format rules, and no indication that both are required, so it does not compensate for the coverage gap.

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 states a specific verb ('Read') and resource ('app bundles and version codes') scoped to 'an existing app edit', which distinguishes it from mutating siblings such as upload_bundle and upload_internal_sharing_bundle. It does not explicitly name a sibling, but the read/list nature is unambiguous.

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 phrase 'existing app edit' implies a prerequisite edit must already exist (created via create_edit), but the description never says so, never mentions what to do when no edit exists, and names no alternative tool. An agent must infer the workflow from sibling names.

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