 ### New Features
 
+- **Elixir** (`.ex`, `.exs`) language support — modules, functions, imports, calls, and HEEx (`.heex`) templates with component extraction.
+- **Grok Build** agent support — `codegraph install` now detects and configures Grok Build (xAI's coding agent CLI) as an MCP server.
 - CodeGraph now indexes **Terraform and OpenTofu** (`.tf`, `.tfvars`, `.tofu`) — resources, data sources, modules, variables, outputs, providers, and every `locals` attribute become symbols (e.g. `aws_s3_bucket.my_bucket`, `var.region`, `module.vpc`, `local.prefix`), and uses like `var.region`, `module.vpc.id`, `data.aws_caller_identity.current`, or `aws_s3_bucket.my.arn` are wired up cross-file, so search, callers, and impact queries return real results on infrastructure repos instead of nothing. Module calls are bridged across the module boundary: a `module` block's inputs link to the child module's variables, `module.vpc.vpc_id` reaches the child's `output "vpc_id"` definition, and the block's local `source` path links to the module's files — so "what breaks if I change this module's variable" reaches every caller instead of dead-ending at the declaration (registry and git sources are deliberately left as visible boundaries rather than guessed). Cross-component wiring through the cloudposse/atmos `remote-state` module connects too: `module.vpc.outputs.vpc_cidr` in one component reaches the `vpc` component's own output when the component name is statically declared (a literal, or a variable with a literal default) and exactly one directory matches — anything dynamic or ambiguous stays unlinked. Aliased providers are first-class: `provider "aws" { alias = "east" }` gets its own symbol, and `provider = aws.east` on a resource (or a module's `providers` map) links to that configuration, found up the module tree the way Terraform actually inherits it. `moved`/`import`/`removed` state-migration blocks and `check` assertions reference the resources they name, so a refactor's paper trail is part of the graph. `.tfvars` assignments link to the variables they set, including var-files kept in a subdirectory. Resolution follows Terraform's real per-directory scoping, so same-named variables across modules never cross-link and "what depends on `var.project_id`" in a multi-module repo never mixes in unrelated modules. Thanks @Javviviii2. (#83, #310, #648)
 - CodeGraph now indexes **CUDA** (`.cu`, `.cuh`) — kernels, device/host functions, structs, and classes become symbols, and the host→kernel call edge survives the `<<<grid, block>>>` launch syntax, so questions like "how does this call reach the GPU kernel?" trace across the CPU/GPU boundary instead of going dark at the launch site. Real-world launch styles all connect: templated launches (`my_kernel<Traits, 256><<<grid, block>>>(args)`), launches through a local function pointer (`auto kernel = &my_kernel<...>; ... kernel<<<grid, block>>>(args)` — each branch-assigned target linked), brace-initialized launch configs (`<<<dim3{1,1,1}, dim3{256,1,1}>>>`), and kernels defined through a name-in-first-argument macro (flash-attention's `DEFINE_FLASH_FORWARD_KERNEL(kernel_name, ...) { ... }` style), which now index under their real kernel names. CUDA that lives in plain `.h`/`.hpp` headers — where much real-world device code sits, launch-template headers included — is recognized by content and indexed the same way. Validated on llm.c, flash-attention, and NVIDIA CUTLASS. (#387, #648)
 - C++ symbols defined inside `namespace` blocks now carry the namespace in their qualified name (`flash::compute_attn`, C++17 `namespace a::b {` included), and namespace-qualified calls (`ns::fn(...)`) resolve to their definitions — previously such calls never linked at all, which hid much of the call graph in namespace-heavy C++ codebases from callers and impact analysis.
