Sideload Channel Package

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

Beyond annotations (destructiveHint true), the description details that the tool replaces any currently sideloaded Dev App, explains temp file cleanup for contentBase64, and warns about sandbox path errors. This adds significant context beyond structured fields.

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 well-structured with a clear main statement followed by method details. However, it is slightly verbose; some sentences could be tightened without losing 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 covers the process well, including cleanup and error behavior for wrong paths. However, it does not explain the return value or success/failure indicators, which would help the agent understand the response. Given the complexity and lack of output schema, it is mostly complete.

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?

Although schema coverage is 100%, the description adds meaningful inter-parameter relationships (mutual exclusivity of filePath and contentBase64) and operational context (temp file handling, sandbox path detection). This goes above the baseline for fully documented schemas.

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 tool uploads and installs a .zip channel package, specifying the verb 'Upload and install' and the resource 'channel package'. It distinguishes from siblings by noting the destructive nature and providing two methods for different environments.

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 gives explicit when-to-use guidance for each parameter combination: filePath for local execution, contentBase64 for remote agent sandboxes. It also explains when password is optional, making usage conditions very clear.

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