Noir — 127 Operations for AI Agents

Noir brings zero-knowledge programs to developers who think in functions, not constraints. act101 reads Noir's structure natively, so agents navigate circuits and their proofs-in-progress like ordinary code.

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze Noir 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.

Premium language. Operations on Noir require an Elite license or above. See pricing.

Operation	Description
`add-contract-storage`	Add a field to Noir contract storage
`add-field`	Add a field to a Noir struct
`add-fold-attribute`	Add #[fold] to a Noir function
`add-parameter`	Add a parameter to a Noir function
`change-parameter-type`	Change a Noir function parameter type
`change-return-type`	Change a Noir function return type
`convert-comptime-to-fn`	Convert a Noir comptime function to runtime execution
`convert-private-to-public`	Convert a private Noir function to public
`convert-public-to-private`	Convert a public Noir function to private
`convert-to-comptime-fn`	Convert a Noir function to comptime execution
`convert-to-constrained`	Convert a Noir function to constrained execution
`convert-to-global-constant`	Extract a Noir value to a global constant
`convert-to-unconstrained`	Convert a Noir function to unconstrained execution
`extract-function`	Extract selected Noir code into a new function
`extract-module`	Extract top-level declarations into an inline Noir module
`extract-struct`	Extract Noir struct fields into a new struct
`extract-to-module`	Extract Noir declarations to a module file
`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)]
`fix-missing-import`	Add a missing Noir use statement
`fix-type-mismatch`	Fix a Noir local variable type mismatch
`fix-unconstrained-in-proof`	Fix unconstrained Noir proof logic
`fix-unused-variable`	Fix an unused Noir local variable
`gen-contract-scaffold`	Generate a Noir contract-style module scaffold
`gen-hash-function`	Generate a Noir hash function wrapper
`gen-integration-test`	Generate a Noir integration-style test
`gen-membership-proof`	Generate a Noir membership proof helper
`gen-note-scaffold`	Generate a Noir note scaffold
`gen-nullifier-check`	Generate Noir nullifier check helpers
`gen-range-proof`	Generate a Noir range proof helper
`gen-storage-layout`	Generate a Noir storage layout struct
`gen-test-function`	Generate a Noir unit test function
`gen-zk-circuit-scaffold`	Generate a Noir ZK circuit function scaffold
`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`	Inline simple Noir function calls
`inline-global-constant`	Inline a Noir global constant
`inline-module`	Inline a Noir module into its parent scope
`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)]
`merge-modules`	Merge two inline Noir modules
`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-contract-storage`	Remove a field from Noir contract storage
`remove-field`	Remove a Noir struct field
`remove-fold-attribute`	Remove #[fold] from a Noir function
`remove-parameter`	Remove an unused Noir function parameter
`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-field`	Rename a Noir struct field and update field access syntax
`rename-function`	Rename a Noir function and update direct call targets
`rename-module`	Rename a Noir module and update module paths
`rename-struct`	Rename a Noir struct and update type and constructor references
`rename-variable`	Rename a Noir local variable inside a function
`reorder-fields`	Reorder fields in a Noir struct
`reorder-parameters`	Reorder Noir function parameters
