# GrepAI Trace Callers This skill covers using `grepai trace callers` to find all code locations that call a specific function or method. ## When to Use This Skill - Finding all usages of a function before refactoring - Understanding function dependencies - Impact analysis before changes - Code navigation and exploration ## What is Trace Callers? `grepai trace callers` answers: **"Who calls this function?"** ``` func Login(user, pass) {...} ↑ │ ┌───────┴───────────────────┐ │ Who calls Login()? │ ├───────────────────────────┤ │ • HandleAuth (auth.go:42) │ │ • TestLogin (test.go:15) │ │ • CLI (main.go:88) │ └───────────────────────────┘ ``` ## Basic Usage ```bash grepai trace callers "FunctionName" ``` ### Example ```bash grepai trace callers "Login" ``` Output: ``` 🔍 Callers of "Login" Found 3 callers: 1. HandleAuth File: handlers/auth.go:42 Context: user.Login(ctx, credentials) 2. TestLoginSuccess File: handlers/auth_test.go:15 Context: result := Login(testUser, testPass) 3. RunCLI File: cmd/main.go:88 Context: err := auth.Login(username, password) ``` ## JSON Output For programmatic use: ```bash grepai trace callers "Login" --json ``` Output: ```json { "query": "Login", "mode": "callers", "count": 3, "results": [ { "file": "handlers/auth.go", "line": 42, "caller": "HandleAuth", "context": "user.Login(ctx, credentials)" }, { "file": "handlers/auth_test.go",
