get_theme_colors

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

With no annotations, the description conveys key behaviors: it reads from a specific XML file, returns a dict of hex strings, and returns empty dict if no theme file. It does not mention side effects or permissions, but for a read-only tool it is sufficiently transparent.

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-loads the purpose, and contains no filler. Every word contributes to understanding.

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 no parameters and an output schema (implied), the description fully covers the tool's behavior, including the edge case of a missing theme file. No additional context is needed.

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?

There are no parameters, so the description does not need to add meaning beyond the schema. The baseline for 0 params is 4, and the description appropriately explains the output without parameter details.

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 returns named color slots from word/theme/theme1.xml, specifies the return format (dict mapping slot names to hex strings), and handles the edge case of no theme file (empty dict). This distinguishes it from sibling tools like get_body_text, get_document_info, etc.

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 theme colors are needed, but does not explicitly state when to use versus alternatives. No exclusions or alternative tools are mentioned.

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