apply_report_theme

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

No annotations are provided, so the description must carry the behavioral burden. It mentions the theme components and that themeJson overrides preset, but it does not disclose whether the theme is entirely replaced, reversibility, permissions required, or any side effects. This is a gap 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 two sentences, front-loaded with the core purpose and immediately followed by parameter usage. No extraneous information; every word earns its place.

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 mutation tool with no output schema, the description gives the necessary invocation details but lacks behavioral specifics like return value, side effects, and differentiation from theme-related siblings. It is adequate but minimal, earning the baseline viability score.

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 already covers preset and themeJson descriptions, but the tool description adds meaning by explaining the role of preset ('executive|vibrant|slate|sunset|forest') and the override relationship. It also clarifies what the theme encompasses (palette, fonts, structural colors), enhancing beyond the 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?

The description clearly states 'Apply a report theme (palette + fonts + structural colours)' with a specific verb and resource. It distinguishes this from sibling theme tools by covering the entire theme (palette, fonts, colors) rather than individual aspects like data colors or structural colors.

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 when wanting a quick professional look ('single biggest lever') and explains how to use presets or themeJson, but it does not explicitly contrast with alternatives like set_theme_data_colors or modify_theme. Guidance is implicit rather than explicit.

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