inboxAppInstall

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

With no annotations provided, the description carries the burden of behavioral disclosure. It states the action and required inputs but does not cover potential side effects, reversibility, authentication needs, or exceptions (e.g., what happens if the app is already installed). This is adequate but not thorough.

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, short sentence (20 words) that communicates the core purpose and requirements without any unnecessary words. It is front-loaded and efficient.

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 tool has three required parameters and no output schema. The description covers the purpose and required inputs but does not explain return values, error conditions, or post-installation behavior. Given the complexity (simple install action), it is complete enough but could benefit from mentioning what the result is or how to verify the installation.

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 100%, so the baseline is 3. The description adds minimal value beyond the schema, merely reiterating that publishedInboxAppId comes from a catalog and that subscriptionUrl is needed. It does not explain parameter constraints or relationships further.

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 ('Install an inbox app for a user') and identifies the key required resources: publishedInboxAppId and subscriptionUrl. It effectively distinguishes this tool from sibling tools like inboxAppDeactivate or inboxAppUpdateConversation.

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 when to use the tool (when installing an app for a user) but does not provide explicit guidance on when not to use it or mention alternative tools. No exclusions or context-specific advice is given.

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