apply_color_palette

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 states 'Set a custom color palette,' implying a mutation operation, but doesn't disclose behavioral traits such as whether this affects all charts globally, requires specific permissions, is reversible, or has side effects. The mention of built-in palettes adds some context but is insufficient 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 brief and front-loaded with the main action, followed by examples. It avoids unnecessary words, but could be more structured by separating custom and built-in usage explicitly. Every sentence adds value, though it's slightly terse.

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?

Given the complexity of a mutation tool with 3 parameters, 0% schema coverage, no annotations, and sibling tools that might overlap, the description is incomplete. It lacks details on when to use, parameter meanings, behavioral effects, and how it integrates with other tools. The presence of an output schema helps but doesn't compensate for these gaps.

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 for all three parameters. It only indirectly hints at 'palette_name' by listing built-in options and 'colors' by mentioning 'custom,' but doesn't explain the purpose of 'custom_name' or the relationship between parameters. No details on format, constraints, or usage are provided.

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 action ('Set a custom color palette') and the resource ('color palette'), making the purpose evident. It distinguishes between custom and built-in palettes by listing examples of built-in ones, though it doesn't explicitly differentiate from sibling tools like 'configure_chart' or 'configure_worksheet_style' that might involve color settings.

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 is provided on when to use this tool versus alternatives. The description mentions built-in palettes but doesn't specify if this tool is for overriding defaults, applying to specific elements, or when to choose custom vs. built-in options. There's no mention of prerequisites or related tools like 'apply_dashboard_theme'.

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