inboxAppInstall

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

Annotations are absent, so the description must convey behavioral context. It only mentions requirements ('Requires the publishedInboxAppId...') but does not disclose side effects, reversibility, permissions, or return behavior, leaving important operational details unknown.

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 short sentences that front-load the purpose and prerequisites without any 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 simple three-parameter schema and absence of an output schema, the description covers the basic purpose but omits information about success/error responses or relationship to other inbox app operations. It is minimally sufficient but lacks rich context.

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?

The input schema provides 100% coverage with descriptions for all three parameters. The tool description adds minimal new meaning, mostly restating that publishedInboxAppId comes from the FUB catalog and subscriptionUrl is a webhook, so it does not significantly exceed schema information.

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 'Install an inbox app for a user' with a specific verb and resource. It effectively distinguishes the tool from siblings like inboxAppDeactivate or inboxAppAddMessage by focusing on the installation action.

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 does not explicitly address when to use this tool versus alternatives like listInboxAppInstallations or inboxAppUpdateConversation. It implies usage for installing an app, but provides no exclusions or alternative recommendations.

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