garageband_annotated_screenshot

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

With no annotations, the description provides transparency about outputs (PNG + JSON) but lacks detail on side effects, permissions, or whether GarageBand is modified. It implies a capture operation but doesn't confirm read-only nature.

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?

Single sentence is concise but too brief given the tool's complexity (7 parameters, no schema descriptions). It omits critical parameter details, making it under-specified rather than 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 description is inadequate for a tool with 7 parameters, no output schema, and no annotations. It does not explain parameters, output format, or behavior, leaving the agent unable to invoke the tool correctly.

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 coverage is 0% and the description fails to explain any of the 7 parameters (e.g., max_depth, include_grid, limit). The agent receives no useful guidance beyond output files mentioned.

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 captures an annotated screenshot of GarageBand with numbered UI targets and a JSON click map, distinguishing it from sibling `garageband_screenshot` which likely produces a plain screenshot.

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?

No guidance on when to use this tool versus alternatives like `garageband_screenshot`. No context on prerequisites (e.g., GarageBand must be running) or exclusions.

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