is_view_visible

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

No annotations are provided, so the description carries the full burden. It clearly indicates a read-only operation (no side effects implied) and lists valid view names. However, it does not disclose error handling, return format, or any special behaviors such as whether the view must be open to check. Adequate for a simple getter but not rich.

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 extremely concise: one clear purpose statement and a parameter explanation with examples. No unnecessary words or repetition. It is front-loaded with the primary function and structured for quick parsing.

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 is simple with one parameter and an output schema present. The description covers the purpose and parameter meaning, which is sufficient for an agent to invoke it. Since an output schema exists, the return value is presumably defined elsewhere, so its absence here is acceptable.

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 schema provides no description for the view_name parameter (schema coverage 0%). The description compensates by listing example values ('Browser', 'Arranger', 'Session', etc.), giving the agent concrete context for what to pass. This adds meaning beyond the schema's bare type definition.

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's function: 'Get whether an Ableton view is currently visible.' This is a specific query about view visibility, distinct from sibling tools like show_view or hide_view. The examples of view names further clarify the resource being queried.

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?

Usage is implied by the description: it is used to check if a view is visible. However, there is no explicit guidance on when to use this tool versus alternatives like get_view_state or focus_view. No exclusions or alternative tool references are provided.

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