Lua — 126 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Lua code through the act MCP server. 126 operations available: 52 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-assert-for-type-safety`	Insert assert(type(x) == '<type>') guard before a field access statement
`add-error-handler`	Wrap function call with xpcall and an inline error handler
`add-ipairs-instead-of-numeric-for`	Convert numeric for i=1,#t loop to idiomatic for i,v in ipairs(t)
`add-local-declaration`	Add local keyword to variable declaration
`add-local-keyword`	Add local keyword to implicit global variable
`add-module-return`	Append return <module_name> to end of Lua module file
`add-pairs-instead-of-while`	Convert for k, v in next, t do pattern to idiomatic for k, v in pairs(t) do
`add-pcall-wrapper`	Wrap function call in pcall for error safety
`convert-global-to-local`	Convert global variable to local with proper scope
`convert-table-operation-to-built-in`	Replace manual table append pattern (t[#t+1]=v) with table.insert()
`convert-to-method-call`	Convert function call to method call syntax
`convert-to-string-library`	Normalise string method-call syntax (s:method()) to string.* stdlib form
`convert-to-table-library`	Replace manual table operations with table.* stdlib functions
`extract-function`	Extract code block into new function
`extract-table`	Extract a table literal into a named local variable
`extract-variable`	Extract expression into local variable
`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 getter/setter functions for a table's fields
`generate-builder`	Generate builder pattern
`generate-class-pattern`	Generate class-like table with methods and instance variables using metatables
`generate-constructor`	Generate a table constructor from fields
`generate-enum-table`	Generate enum-like table with named constants and sequential integer values
`generate-equals`	Generate equals/eq comparison method
`generate-error-handler`	Generate error handling wrapper function using xpcall
`generate-from-json`	Generate JSON deserialization
`generate-hash`	Generate hash/hashCode method
`generate-impl`	Generate interface/trait impl stubs
`generate-iterator-function`	Generate custom iterator function for for...in usage
`generate-module-exports`	Generate explicit module export assignments for all unexported functions
`generate-module-scaffold`	Generate a standard Lua module scaffold with metadata fields
`generate-to-json`	Generate JSON serialization
`generate-to-string`	Generate string representation
`import-add`	Add a local require binding
`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-variable`	Inline local variable into call sites
`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)]
`introduce-parameter`	Convert expression to function parameter
`invert-conditional`	Invert if-else structure and negate condition
`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)]
`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-dead-code`	Remove unreachable code after return or break statement
`remove-local-keyword`	Remove local keyword when not needed
`remove-unused-function`	Remove function definitions that are never called in the module
`remove-unused-parameter`	Remove function parameters that are never referenced in the body
`remove-unused-variable`	Remove local variable declarations that are never 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-identifier`	Rename variable, function, or table field across references
`simplify-conditional`	Simplify if block with always-true or always-false literal condition
`wrap-if`	Wrap code in if statement
`wrap-null-check`	Add null/undefined check guard
`wrap-try-catch`	Wrap code in try-catch block
