extract_figma_tokens

Converts Figma variable definitions into standardized design token formats (W3C, Tokens Studio, Style Dictionary) with type inference and collection mapping for syncing to local token systems.

Instructions

Extract Figma variables and convert to standardized token formats (W3C, Tokens Studio, Style Dictionary). Takes Figma variable definitions from mcp_figma_get_variable_defs and transforms them into design tokens with proper type inference, collection mapping, and metadata. Useful for syncing Figma variables to your local token system.

Behavior2/5

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

No annotations provided; description lacks behavioral details such as side effects, permissions, or whether it is read-only beyond the stated transformation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with main action and context, no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers input, output formats, and filtering sufficiently; lacks error handling or performance notes but adequate for a transformation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%; description adds context by specifying input source (mcp_figma_get_variable_defs) and explains features like type inference and collection mapping.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Describes specific verb (extract/convert) and resource (Figma variables to standardized token formats), clearly distinguishing from siblings like validate_figma_tokens or extract_styles.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Mentions usefulness for syncing Figma variables but does not explicitly state when not to use or suggest alternatives among many sibling tools.

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