Odin — 113 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Odin code through the act MCP server. 113 operations available: 39 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-function-parameter`	Add a parameter to a function definition
`add-import`	Add import statement for a package at top of file
`add-null-check`	Wrap statement with null check guard
`add-package-qualifier`	Add package prefix to unqualified function calls
`add-struct-field`	Add a new field to a struct definition
`convert-for-to-while`	Convert for loop to while loop with index counter
`convert-if-to-switch`	Convert chained if statements to switch statement
`convert-pointer-to-value`	Convert pointer type to value type
`convert-struct-to-named-type`	Convert anonymous struct to named type definition
`convert-switch-to-if`	Convert simple switch statement to if statement chain
`convert-value-to-pointer`	Convert value type to pointer type
`convert-while-to-for`	Convert while loop with index to for loop
`extract-function`	Extract code block into new named function
`extract-variable`	Extract expression into named 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-equality-check`	Generate equality check function for a struct
`generate-error-check`	Generate error checking procedure for a function
`generate-function-stub`	Generate empty function with signature
`generate-string-builder-impl`	Generate string building utilities for a type
`generate-test-procedure`	Generate test procedure for a given function
`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`	Replace function call with function body
`inline-variable`	Replace variable reference with assigned 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)]
`invert-if-expression`	Swap condition and branches of an if statement
`merge-imports`	Merge multiple import statements for the same package
`move-function-to-file`	Move function definition from current file to target 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)]
`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-function-parameter`	Remove a parameter from a function definition
`remove-package-qualifier`	Remove package prefix from qualified function calls
`remove-struct-field`	Remove a field from a struct definition
`remove-unused-import`	Remove import statement if package is not referenced
`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-function`	Rename a function and update all call sites
`rename-struct`	Rename a struct and update all usages
`rename-variable`	Rename a variable across all references in the same scope
`simplify-if-expression`	Simplify if expression that returns boolean values
