code_rename_symbol

code_rename_symbol finds every definition, call site, import, and type reference for a symbol so you know exactly what a rename will touch — before making any changes. Always run in dry-run mode first.

Usage

code_rename_symbol(old_name="processUser", new_name="handleUser", dry_run=true)

Parameters

Parameter	Type	Default	Description
`old_name`	string	required	Current symbol name
`new_name`	string	required	Desired new name
`dry_run`	boolean	true	Preview changes without writing files

Output

Rename: processUser → handleUser
Locations to update (7):

  src/services/user.ts:44          definition
  src/controllers/user.ts:31       call site
  src/controllers/admin.ts:88      call site
  src/middleware/auth.ts:22        call site
  src/types/user.d.ts:12           type reference
  tests/user.test.ts:14            call site
  tests/integration/user.test.ts:9 call site

Safe rename workflow

# Step 1: preview (always)
code_rename_symbol(old_name="processUser", new_name="handleUser", dry_run=true)

# Step 2: review each location
code_get(name="processUser")

# Step 3: make the change, then verify
code_build()

When to use

Before any rename to understand the full blast radius
When a function has spread across many files and you are unsure of all usages
As a safety check before automated refactoring
