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.

Refactor

Operation Description
add-cmdlet-binding Add [CmdletBinding()] attribute to a function
add-module-import Add an Import-Module statement for a given module
add-null-guard Add a null check guard before a variable usage
add-output-type Add [OutputType()] attribute to a function
add-parameter-type-constraint Add a [TypeName] type constraint to a function parameter
add-requires-statement Add a #Requires statement at the top of the script
add-using-module Add a using module statement for a given module
change-signature Modify a function's parameter list and update all call sites
change-visibility 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-here-string-to-string-interpolation Convert a here-string to an inline string interpolation
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 formatting to PowerShell string interpolation
convert-string-literal-to-here-string Convert a regular string literal to a PowerShell here-string
convert-switch-to-if Convert a switch statement to an if/elseif/else chain
convert-variable-mutability Convert a variable between mutable and read-only using Set-Variable
convert-write-host-to-write-output Replace Write-Host calls with Write-Output for pipeline compatibility
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
