PowerShell — 128 Operations for AI Agents
This page is the canonical reference an AI coding agent uses to refactor, query, and analyze PowerShell code through the act MCP server. 128 operations available: 54 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.

Change the scope modifier of a variable or function |
comment-out-statement |
Comment out one or more lines by prefixing each with # |
convert-alias-to-full-cmdlet |
Replace a cmdlet alias with its full cmdlet name |
convert-for-to-foreach |
Convert an index-based for loop to a foreach loop |
convert-foreach-to-for |
Convert a foreach loop to an index-based for loop |
convert-function-form |
Convert between function, filter, and workflow keyword forms |

convert-if-to-switch |
Convert an if/elseif/else chain to a switch statement |
convert-member-access-to-property |
Convert a .get_Name() getter call to direct .Name property access |
convert-string-format |

convert-string-literal-to-here-string |
Convert a regular string literal to a PowerShell here-string |
convert-switch-to-if |

convert-write-host-to-write-output |

expand-string-interpolation |
Expand a string interpolation expression into explicit concatenation |
extract-function |
Extract a block of code into a new function |
extract-interface |
Extract a PowerShell class interface definition |
extract-variable |
Extract an expression into a 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-constructor |
Generate a constructor method for a PowerShell class |
generate-equality |
Generate Equals() and GetHashCode() for a PowerShell class |
generate-function |
Generate a function stub at the cursor position |
generate-help-comment |
Generate a PowerShell comment-based help block before a function |
generate-impl-stubs |
Generate stub implementations for interface methods in a class |
generate-pester-test |
Generate a Pester test scaffold for a function |
generate-property-getter-setter |
Generate getter and setter methods for a class property |
generate-tostring |
Generate a ToString() override for a PowerShell class |
import-alias |
Add or update a New-Alias or Set-Alias for a module import |
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 a function call by replacing it with the function body |
inline-variable |
Inline a variable by replacing it with its value at all usages |
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-boolean-condition |
Invert a boolean condition in a conditional expression |
move-symbol |
Move a function or variable definition to another 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-imports |
Sort and deduplicate Import-Module and using statements |
promote-variable-to-parameter |
Promote a local variable to a function parameter |
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-unused-import |
Remove an unused Import-Module statement |
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 a variable, function, or cmdlet alias across all references |
set-strict-mode |
Add Set-StrictMode -Version Latest to enforce strict variable usage |
simplify-conditional |
Simplify a redundant or over-complex conditional expression |
uncomment-statement |
Remove the leading # comment marker from one or more lines |
wrap-try-catch |
Wrap a block of code in a try/catch error handling block |
