Recolor pane

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

No annotations are provided, so the description must carry the full burden. It discloses 'applied live' and acceptance of any CSS color string, which are useful behavioral traits. However, it does not mention error handling, permissions, reversibility, or side effects, leaving significant gaps for a mutation tool.

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 just two concise, front-loaded sentences. It states the action and the key input format without any waste. The example adds practical value.

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 two required parameters, the description covers the main action, target, and color format. It lacks details on error behavior or prerequisites, but for a straightforward live-recolor operation, it is reasonably complete. No output schema exists, so return value explanation is not required.

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 description coverage is 0%, so the description must compensate. It explains 'color' with a concrete example and format, but 'paneId' is only implied through the phrase 'a pane's frame color' rather than explicitly described. This partially compensates but leaves a clear gap.

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 a specific action ('Change a pane's frame color') with a distinct resource ('pane's frame color'), and the 'applied live' detail adds specificity. This differentiates it from sibling tools like recolor_project.

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 (to change a pane's frame color), but there is no explicit guidance on when to use this tool versus alternatives like recolor_project, nor any exclusions or prerequisites. The context is clear but lacks explicit direction.

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