Common Lisp — 151 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Common Lisp code through the act MCP server. 151 operations available: 77 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.

`add-type-declaration`	Add type declaration to function parameter
`change-signature`	Modify function parameters, return, generics
`convert-case-to-cond`	Rewrite case expression as cond
`convert-cond-to-if-when`	Replace single-clause cond with if/when
`convert-format-to-string-concatenation`	Replace format nil with concatenate string
`convert-if-to-cond`	Replace if expression with cond
`convert-if-when-to-cond`	Merge if/when chain into cond
`convert-let-to-letstar`	Change let to let* for sequential bindings
`convert-letstar-to-let`	Change let* to let when bindings are independent
`convert-loop-to-recursion`	Rewrite loop macro as recursive function
`convert-macro-to-function`	Convert defmacro to defun
`convert-positional-to-keyword`	Move positional parameter to &key section
`convert-progn-to-let`	Replace progn with let binding
`convert-recursion-to-loop`	Rewrite recursive function as loop macro
`convert-slot-to-accessor`	Replace slot-value call with accessor method
`convert-string-concatenation-to-format`	Replace concatenate string with format nil
`encapsulate`	Make field private, generate getter/setter
`extract-constant`	Extract value to named constant
`extract-function`	Extract code range to new function
`extract-interface`	Create interface from class
`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-accessors`	Generate getters/setters for fields
`generate-builder`	Generate builder pattern
`generate-condition-class`	Generate define-condition form for errors
`generate-constructor`	Generate constructor from fields
`generate-defclass-skeleton`	Generate minimal defclass skeleton
`generate-documentation-template`	Generate documentation comment template
`generate-equals`	Generate equals/eq comparison method
`generate-from-json`	Generate JSON deserialization
`generate-hash`	Generate hash/hashCode method
`generate-impl`	Generate interface/trait impl stubs
`generate-package-definition`	Generate defpackage with in-package form
`generate-to-json`	Generate JSON serialization
`generate-to-string`	Generate string representation
`import-add`	Add a (require :module) form
`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)]
`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)]
`lift-expression`	Extract subexpression to outer let binding
`lisp-add-parentheses`	Wrap expression in additional parentheses
`lisp-extract-function`	Extract form into a new named defun
`lisp-extract-variable`	Extract expression into a let binding
`lisp-generate-defclass-with-slots`	Generate defclass form with slot definitions
`lisp-generate-defgeneric`	Generate defgeneric form for a generic function
`lisp-generate-defmethod`	Generate defmethod implementation for a generic
`lisp-generate-function-stub`	Generate stub defun with parameter list
`lisp-generate-print-object-method`	Generate print-object method for a class
`lisp-generate-slot-accessor`	Generate slot accessor methods for a defclass
`lisp-generate-test-scaffold`	Generate test scaffold with setup/teardown
`lisp-generate-unit-test-from-function`	Generate unit test from existing defun signature
`lisp-inline-function`	Inline single-use defun at call site
`lisp-inline-variable`	Inline let binding at use site
`lisp-invert-conditional`	Invert if condition and swap branches
`lisp-remove-parentheses`	Remove unnecessary outer parentheses
`lisp-rename-symbol`	Rename symbol throughout the file
`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)]
`organize-use-package-imports`	Sort and deduplicate :use clauses in defpackage
`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-export-declaration`	Remove symbol from package exports
`remove-keyword-argument`	Remove keyword argument from function definition, update all callers
`remove-optional-argument`	Remove optional parameter from function definition, update all callers
`remove-package-declaration`	Remove defpackage form from file
`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)]
`split-function-definition`	Extract last body form into a new helper defun
`unwrap-lambda`	Remove wrapping lambda, expose inner expression
`wrap-in-lambda`	Wrap expression in a (lambda () ...)
