SCSS/Sass — 127 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze SCSS/Sass code through the act MCP server. 127 operations available: 53 refactor, 18 query, 42 analysis, 14 verification. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Refactor

Operation	Description
`add-extend-directive-scss`	Add @extend for selector inheritance
`add-forward-statement-scss`	Add @forward for re-exporting modules
`add-global-variable-scss`	Add !global flag to variable
`add-interpolation-scss`	Add #{} interpolation
`add-list-variable-scss`	Add list variable ($list: val1, val2)
`add-map-variable-scss`	Add map ($map: (key: val))
`add-mixin-default-param-scss`	Add default value to mixin parameter
`add-mixin-parameter-scss`	Add parameter to existing @mixin
`add-module-config-scss`	Add module configuration with @use
`add-use-statement-scss`	Add @use import for modules
`consolidate-mixins-scss`	Merge similar mixins
`convert-at-import-to-at-use-scss`	Migrate @import to @use
`convert-each-to-loop-scss`	Convert @each to explicit loop
`convert-if-to-ternary-scss`	Convert @if to ternary when possible
`convert-list-to-map-scss`	Convert list to map structure
`convert-nested-to-flat-scss`	Convert nested selectors to flat CSS
`extract-function-scss`	Extract expression to @function
`extract-mixin-scss`	Extract repeated code to a @mixin
`extract-to-nested-selector-scss`	Extract to nested selector pattern
`extract_function`	Extract a code selection into a new function — automatically infers parameters, return types, and inserts the call site. Use instead of manually cutting/pasting code. Works without LSP; LSP improves type inference. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool), receipt (bool)]
`extract_variable`	Extract an expression into a named variable — inserts the declaration and replaces the expression with the variable name. Works without LSP. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool)]
`generate-animation-mixin-scss`	Generate animation @keyframes mixin
`generate-breakpoint-mixin-scss`	Generate responsive breakpoint mixin
`generate-button-mixin-scss`	Generate button component mixin
`generate-card-mixin-scss`	Generate card component mixin
`generate-color-map-scss`	Generate color palette map
`generate-flex-mixin-scss`	Generate flexbox mixin
`generate-form-mixin-scss`	Generate form element mixin
`generate-function-scss`	Generate @function skeleton with @return
`generate-grid-mixin-scss`	Generate CSS grid mixin
`generate-media-query-scss`	Generate @media query mixin
`generate-mixin-scss`	Generate @mixin skeleton with parameters
`generate-spacing-map-scss`	Generate spacing scale map
`generate-variable-declaration-scss`	Generate SCSS variable ($name: value;)
`inline`	Inline a variable, function, or method — replace every usage with its definition body, then remove the original. The inverse of extract. Works without LSP (single-file); LSP enables cross-file inlining. Params: file (string), symbol (string) [, line (u32), preview (bool), receipt (bool)]
`inline-function-scss`	Inline function call back to expression
`inline-mixin-scss`	Inline a @include back to the original code
`inline-variable-scss`	Replace variable usage with its value
`insert_body`	Replace a function's implementation body with new code. AST-validated — rejects if the result has parse errors, so you can't accidentally break syntax. Use instead of manual text editing for function rewrites. Params: file (string), symbol (string), code (string) [, commit (bool)]
`move_symbol`	Move a function, class, or type to a different file and automatically update all imports across the codebase. Use instead of manually cut/paste + fixing imports. Works without LSP (single-file); LSP enables cross-file import updates. Params: file (string), symbol (string), destination (string) [, preview (bool), receipt (bool)]
`nest-rule-scss`	Nest rule inside parent selector
`organize-mixins-by-category-scss`	Organize mixins by category
`organize-mixins-scss`	Group mixins by functionality
`organize-variables-scss`	Group related variables together
`recipe_run`	Run a codemod recipe: declarative match → transform → optional verify across modeled grammars. Preview lists matches; apply writes with optional E7 receipts and all-or-nothing rollback. Returns a per-site report.
`remove-duplicate-mixin-scss`	Remove duplicate mixin definitions
`remove-unused-variable-scss`	Remove variables that aren't used
`rename`	Rename a symbol and automatically update ALL references across the codebase. Safer and faster than find-and-replace — AST-aware, won't rename strings or comments. Works without LSP (single-file); LSP enables cross-file renames. Params: file (string), old_name (string), new_name (string) [, line (u32), column (u32), preview (bool), receipt (bool)]
`rename-mixin-scss`	Rename @mixin and update @include calls
`rename-scss-variable`	Rename SCSS variable ($var) across all references
`simplify-mixin-logic-scss`	Simplify conditional logic in mixins
`simplify-nested-rules-scss`	Flatten unnecessary nesting
`unnest-rule-scss`	Unnest rule to flat selector
