get_picture_settings

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It states a read operation but lacks details on side effects, permissions, or idempotency. For a simple read tool, this is minimal transparency.

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, no redundancy, front-loaded with the action and specific parameters. Every word serves a purpose.

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?

With no output schema, the description should indicate the return format. It only lists the settings read but does not describe the structure (e.g., key-value pairs, units). Incomplete for a read tool.

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?

Input schema has no parameters, and description coverage is 100% (vacuously). The description adds value by enumerating the specific settings read (backlight, contrast, brightness, color), which clarifies the scope beyond the empty schema.

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?

Description clearly states the tool reads current picture settings for backlight, contrast, brightness, and color. It uses a specific verb ('Read') and identifies the resource ('picture settings') with explicit parameters. This distinguishes it from sibling tools like set_backlight or set_picture_mode.

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 usage for retrieving current settings but does not explicitly state when to use this tool versus alternatives like set_picture_setting or when not to use it. No guidance on prerequisites or use cases beyond the basic read operation.

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