apply_saved_layout

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

No annotations are provided, so the description fully carries the burden. It discloses the macOS limitation (windows appear then jump), the return of per-app success, and the timeout for large workspaces. This is comprehensive behavioral information beyond the 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?

The description is longer than necessary but every sentence adds value: purpose, legacy note, behavior, platform quirk, return info, and latency. It is front-loaded with the primary action and remains structured, though slightly verbose.

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 simple tool with one parameter and no annotations or output schema, the description covers all essential aspects: what it does, how it behaves, what it returns, performance caveats, and sibling differentiation. It is complete for effective selection and invocation.

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?

With only one string parameter and zero schema description coverage, the description explains 'by name' to indicate the parameter refers to the saved workspace name. It could add format specifics (e.g., exact matching), but the meaning is clear enough.

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 launches a saved workspace by name, and distinguishes it from the successor launch_workspace, which adds a screen option. It uses a specific verb and resource, providing a clear, unambiguous purpose.

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 instructs new integrations to use launch_workspace instead, giving clear guidance on when not to use this tool. It also describes the behavior of opening apps and waiting for windows, informing usage expectations.

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