+# Adding a New Backend
+
+When adding a new backend to LocalAI, you need to update several files to ensure the backend is properly built, tested, and registered. Here's a step-by-step guide based on the pattern used for adding backends like `moonshine`:
+
+## 1. Create Backend Directory Structure
+
+Create the backend directory under the appropriate location:
+- **Python backends**: `backend/python/<backend-name>/`
+- **Go backends**: `backend/go/<backend-name>/`
+- **C++ backends**: `backend/cpp/<backend-name>/`
+
+For Python backends, you'll typically need:
+- `backend.py` - Main gRPC server implementation
+- `Makefile` - Build configuration
+- `install.sh` - Installation script for dependencies
+- `protogen.sh` - Protocol buffer generation script
+- `requirements.txt` - Python dependencies
+- `run.sh` - Runtime script
+- `test.py` / `test.sh` - Test files
+
+## 2. Add Build Configurations to `.github/workflows/backend.yml`
+
+Add build matrix entries for each platform/GPU type you want to support. Look at similar backends (e.g., `chatterbox`, `faster-whisper`) for reference.
+
+**Placement in file:**
+- CPU builds: Add after other CPU builds (e.g., after `cpu-chatterbox`)
+- CUDA 12 builds: Add after other CUDA 12 builds (e.g., after `gpu-nvidia-cuda-12-chatterbox`)
+- CUDA 13 builds: Add after other CUDA 13 builds (e.g., after `gpu-nvidia-cuda-13-chatterbox`)
+
+**Additional build types you may need:**
+- ROCm/HIP: Use `build-type: 'hipblas'` with `base-image: "rocm/dev-ubuntu-24.04:6.4.4"`
+- Intel/SYCL: Use `build-type: 'intel'` or `build-type: 'sycl_f16'`/`sycl_f32` with `base-image: "intel/oneapi-basekit:2025.3.0-0-devel-ubuntu24.04"`
+- L4T (ARM): Use `build-type: 'l4t'` with `platforms: 'linux/arm64'` and `runs-on: 'ubuntu-24.04-arm'`
+
+## 3. Add Backend Metadata to `backend/index.yaml`
+
+**Step 3a: Add Meta Definition**
+
+Add a YAML anchor definition in the `## metas` section (around line 2-300). Look for similar backends to use as a template such as `diffusers` or `chatterbox`
+
+**Step 3b: Add Image Entries**
+
+Add image entries at the end of the file, following the pattern of similar backends such as `diffusers` or `chatterbox`. Include both `latest` (production) and `master` (development) tags.
+
+## 4. Update the Makefile
+
+The Makefile needs to be updated in several places to support building and testing the new backend:
+
+**Step 4a: Add to `.NOTPARALLEL`**
+
+Add `backends/<backend-name>` to the `.NOTPARALLEL` line (around line 2) to prevent parallel execution conflicts:
+
+```makefile
+.NOTPARALLEL: ... backends/<backend-name>
+```
+
+**Step 4b: Add to `prepare-test-extra`**
+
+Add the backend to the `prepare-test-extra` target (around line 312) to prepare it for testing:
+
+```makefile
+prepare-test-extra: protogen-python
+	...
+	$(MAKE) -C backend/python/<backend-name>
+```
+
+**Step 4c: Add to `test-extra`**
+
+Add the backend to the `test-extra` target (around line 319) to run its tests:
+
+```makefile
+test-extra: prepare-test-extra
+	...
+	$(MAKE) -C backend/python/<backend-name> test
+```
+
+**Step 4d: Add Backend Definition**
+
+Add a backend definition variable in the backend definitions section (around line 428-457). The format depends on the backend type:
+
+**For Python backends with root context** (like `faster-whisper`, `coqui`):
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|python|.|false|true
+```
+
+**For Python backends with `./backend` context** (like `chatterbox`, `moonshine`):
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|python|./backend|false|true
+```
+
+**For Go backends**:
+```makefile
+BACKEND_<BACKEND_NAME> = <backend-name>|golang|.|false|true
+```
+
+**Step 4e: Generate Docker Build Target**
+
+Add an eval call to generate the docker-build target (around line 480-501):
+
+```makefile
+$(eval $(call generate-docker-build-target,$(BACKEND_<BACKEND_NAME>)))
+```
+
+**Step 4f: Add to `docker-build-backends`**
+
+Add `docker-build-<backend-name>` to the `docker-build-backends` target (around line 507):
+
+```makefile
+docker-build-backends: ... docker-build-<backend-name>
+```
+
+**Determining the Context:**
+
+- If the backend is in `backend/python/<backend-name>/` and uses `./backend` as context in the workflow file, use `./backend` context
+- If the backend is in `backend/python/<backend-name>/` but uses `.` as context in the workflow file, use `.` context
+- Check similar backends to determine the correct context
+
+## 5. Verification Checklist
+
+After adding a new backend, verify:
+
+- [ ] Backend directory structure is complete with all necessary files
+- [ ] Build configurations added to `.github/workflows/backend.yml` for all desired platforms
+- [ ] Meta definition added to `backend/index.yaml` in the `## metas` section
+- [ ] Image entries added to `backend/index.yaml` for all build variants (latest + development)
+- [ ] Tag suffixes match between workflow file and index.yaml
+- [ ] Makefile updated with all 6 required changes (`.NOTPARALLEL`, `prepare-test-extra`, `test-extra`, backend definition, docker-build target eval, `docker-build-backends`)
+- [ ] No YAML syntax errors (check with linter)
+- [ ] No Makefile syntax errors (check with linter)
+- [ ] Follows the same pattern as similar backends (e.g., if it's a transcription backend, follow `faster-whisper` pattern)
+
+## 6. Example: Adding a Python Backend
+
+For reference, when `moonshine` was added:
+- **Files created**: `backend/python/moonshine/{backend.py, Makefile, install.sh, protogen.sh, requirements.txt, run.sh, test.py, test.sh}`
+- **Workflow entries**: 3 build configurations (CPU, CUDA 12, CUDA 13)
+- **Index entries**: 1 meta definition + 6 image entries (cpu, cuda12, cuda13 x latest/development)
+- **Makefile updates**:
+  - Added to `.NOTPARALLEL` line
+  - Added to `prepare-test-extra` and `test-extra` targets
+  - Added `BACKEND_MOONSHINE = moonshine|python|./backend|false|true`
+  - Added eval for docker-build target generation
+  - Added `docker-build-moonshine` to `docker-build-backends`

+# API Endpoints and Authentication
+
+This guide covers how to add new API endpoints and properly integrate them with the auth/permissions system.
+
+## Architecture overview
+
+Authentication and authorization flow through three layers:
+
+1. **Global auth middleware** (`core/http/auth/middleware.go` → `auth.Middleware`) — applied to every request in `core/http/app.go`. Handles session cookies, Bearer tokens, API keys, and legacy API keys. Populates `auth_user` and `auth_role` in the Echo context.
+2. **Feature middleware** (`auth.RequireFeature`) — per-feature access control applied to route groups or individual routes. Checks if the authenticated user has the specific feature enabled.
+3. **Admin middleware** (`auth.RequireAdmin`) — restricts endpoints to admin users only.
+
+When auth is disabled (no auth DB, no legacy API keys), all middleware becomes pass-through (`auth.NoopMiddleware`).
+
+## Adding a new API endpoint
+
+### Step 1: Create the handler
+
+Write the endpoint handler in the appropriate package under `core/http/endpoints/`. Follow existing patterns:
+
+```go
+// core/http/endpoints/localai/my_feature.go
+func MyFeatureEndpoint(app *application.Application) echo.HandlerFunc {
+    return func(c echo.Context) error {
+        // Use auth.GetUser(c) to get the authenticated user (may be nil if auth is disabled)
+        user := auth.GetUser(c)
+
+        // Your logic here
+        return c.JSON(http.StatusOK, result)
+    }
+}
+```
+
+### Step 2: Register routes
+
+Add routes in the appropriate file under `core/http/routes/`. The file you use depends on the endpoint category:
+
+| File | Category |
+|------|----------|
+| `routes/openai.go` | OpenAI-compatible API endpoints (`/v1/...`) |
+| `routes/localai.go` | LocalAI-specific endpoints (`/api/...`, `/models/...`, `/backends/...`) |
+| `routes/agents.go` | Agent pool endpoints (`/api/agents/...`) |
+| `routes/auth.go` | Auth endpoints (`/api/auth/...`) |
+| `routes/ui_api.go` | UI backend API endpoints |
+
+### Step 3: Apply the right middleware
+
+Choose the appropriate protection level:
+
+#### No auth required (public)
+Exempt paths bypass auth entirely. Add to `isExemptPath()` in `middleware.go` or use the `/api/auth/` prefix (always exempt). Use sparingly — most endpoints should require auth.
+
+#### Standard auth (any authenticated user)
+The global middleware already handles this. API paths (`/api/`, `/v1/`, etc.) automatically require authentication when auth is enabled. You don't need to add any extra middleware.
+
+```go
+router.GET("/v1/my-endpoint", myHandler)  // auth enforced by global middleware
+```
+
+#### Admin only
+Pass `adminMiddleware` to the route. This is set up in `app.go` and passed to `Register*Routes` functions:
+
+```go
+// In the Register function signature, accept the middleware:
+func RegisterMyRoutes(router *echo.Echo, app *application.Application, adminMiddleware echo.MiddlewareFunc) {
+    router.POST("/models/apply", myHandler, adminMiddleware)
+}
+```
+
+#### Feature-gated
+For endpoints that should be toggleable per-user, use feature middleware. There are two approaches:
+
+**Approach A: Route-level middleware** (preferred for groups of related endpoints)
+
+```go
+// In app.go, create the feature middleware:
+myFeatureMw := auth.RequireFeature(application.AuthDB(), auth.FeatureMyFeature)
+
+// Pass it to the route registration function:
+routes.RegisterMyRoutes(e, app, myFeatureMw)
+
+// In the routes file, apply to a group:
+g := e.Group("/api/my-feature", myFeatureMw)
+g.GET("", listHandler)
+g.POST("", createHandler)
+```
+
+**Approach B: RouteFeatureRegistry** (preferred for individual OpenAI-compatible endpoints)
+
+Add an entry to `RouteFeatureRegistry` in `core/http/auth/features.go`. The `RequireRouteFeature` global middleware will automatically enforce it:
+
+```go
+var RouteFeatureRegistry = []RouteFeature{
+    // ... existing entries ...
+    {"POST", "/v1/my-endpoint", FeatureMyFeature},
+}
+```
+
+## Adding a new feature
+
+When you need a new toggleable feature (not just a new endpoint under an existing feature):
+
+### 1. Define the feature constant
+
+Add to `core/http/auth/permissions.go`:
+
+```go
+const (
+    // Add to the appropriate group:
+    // Agent features (default OFF for new users)
+    FeatureMyFeature = "my_feature"
+
+    // OR API features (default ON for new users)
+    FeatureMyFeature = "my_feature"
+)
+```
+
+Then add it to the appropriate slice:
+
+```go
+// Default OFF — user must be explicitly granted access:
+var AgentFeatures = []string{..., FeatureMyFeature}
+
+// Default ON — user has access unless explicitly revoked:
+var APIFeatures = []string{..., FeatureMyFeature}
+```
+
+### 2. Add feature metadata
+
+In `core/http/auth/features.go`, add to the appropriate `FeatureMetas` function so the admin UI can display it:
+
+```go
+func AgentFeatureMetas() []FeatureMeta {
+    return []FeatureMeta{
+        // ... existing ...
+        {FeatureMyFeature, "My Feature", false},  // false = default OFF
+    }
+}
+```
+
+### 3. Wire up the middleware
+
+In `core/http/app.go`:
+
+```go
+myFeatureMw := auth.RequireFeature(application.AuthDB(), auth.FeatureMyFeature)
+```
+
+Then pass it to the route registration function.
+
+### 4. Register route-feature mappings (if applicable)
+
+If your feature gates standard API endpoints (like `/v1/...`), add entries to `RouteFeatureRegistry` in `features.go` instead of using per-route middleware.
+
+## Accessing the authenticated user in handlers
+
+```go
+import "github.com/mudler/LocalAI/core/http/auth"
+
+func MyHandler(c echo.Context) error {
+    // Get the user (nil when auth is disabled or unauthenticated)
+    user := auth.GetUser(c)
+    if user == nil {
+        // Handle unauthenticated — or let middleware handle it
+    }
+
+    // Check role
+    if user.Role == auth.RoleAdmin {
+        // admin-specific logic
+    }
+
+    // Check feature access programmatically (when you need conditional behavior, not full blocking)
+    if auth.HasFeatureAccess(db, user, auth.FeatureMyFeature) {
+        // feature-specific logic
+    }
+
+    // Check model access
+    if !auth.IsModelAllowed(db, user, modelName) {
+        return c.JSON(http.StatusForbidden, ...)
+    }
+}
+```
+
+## Middleware composition patterns
+
+Middleware can be composed at different levels. Here are the patterns used in the codebase:
+
+### Group-level middleware (agents pattern)
+```go
+// All routes in the group share the middleware
+g := e.Group("/api/agents", poolReadyMw, agentsMw)
+g.GET("", listHandler)
+g.POST("", createHandler)
+```
+
+### Per-route middleware (localai pattern)
+```go
+// Individual routes get middleware as extra arguments
+router.POST("/models/apply", applyHandler, adminMiddleware)
+router.GET("/metrics", metricsHandler, adminMiddleware)
+```
+
+### Middleware slice (openai pattern)
+```go
+// Build a middleware chain for a handler
+chatMiddleware := []echo.MiddlewareFunc{
+    usageMiddleware,
+    traceMiddleware,
+    modelFilterMiddleware,
+}
+app.POST("/v1/chat/completions", chatHandler, chatMiddleware...)
+```
+
+## Error response format
+
+Always use `schema.ErrorResponse` for auth/permission errors to stay consistent with the OpenAI-compatible API:
+
+```go
+return c.JSON(http.StatusForbidden, schema.ErrorResponse{
+    Error: &schema.APIError{
+        Message: "feature not enabled for your account",
+        Code:    http.StatusForbidden,
+        Type:    "authorization_error",
+    },
+})
+```
+
+Use these HTTP status codes:
+- `401 Unauthorized` — no valid credentials provided
+- `403 Forbidden` — authenticated but lacking permission
+- `429 Too Many Requests` — rate limited (auth endpoints)
+
+## Usage tracking
+
+If your endpoint should be tracked for usage (token counts, request counts), add the `usageMiddleware` to its middleware chain. See `core/http/middleware/usage.go` and how it's applied in `routes/openai.go`.
+
+## Path protection rules
+
+The global auth middleware classifies paths as API paths or non-API paths:
+
+- **API paths** (always require auth when auth is enabled): `/api/`, `/v1/`, `/models/`, `/backends/`, `/backend/`, `/tts`, `/vad`, `/video`, `/stores/`, `/system`, `/ws/`, `/metrics`
+- **Exempt paths** (never require auth): `/api/auth/` prefix, anything in `appConfig.PathWithoutAuth`
+- **Non-API paths** (UI, static assets): pass through without auth — the React UI handles login redirects client-side
+
+If you add endpoints under a new top-level path prefix, add it to `isAPIPath()` in `middleware.go` to ensure it requires authentication.
+
+## Checklist
+
+When adding a new endpoint:
+
+- [ ] Handler in `core/http/endpoints/`
+- [ ] Route registered in appropriate `core/http/routes/` file
+- [ ] Auth level chosen: public / standard / admin / feature-gated
+- [ ] If feature-gated: constant in `permissions.go`, metadata in `features.go`, middleware in `app.go`
+- [ ] If new path prefix: added to `isAPIPath()` in `middleware.go`
+- [ ] If OpenAI-compatible: entry in `RouteFeatureRegistry`
+- [ ] If token-counting: `usageMiddleware` added to middleware chain
+- [ ] Error responses use `schema.ErrorResponse` format
+- [ ] Tests cover both authenticated and unauthenticated access

+# Build and Testing
+
+Building and testing the project depends on the components involved and the platform where development is taking place. Due to the amount of context required it's usually best not to try building or testing the project unless the user requests it. If you must build the project then inspect the Makefile in the project root and the Makefiles of any backends that are effected by changes you are making. In addition the workflows in .github/workflows can be used as a reference when it is unclear how to build or test a component. The primary Makefile contains targets for building inside or outside Docker, if the user has not previously specified a preference then ask which they would like to use.
+
+## Building a specified backend
+
+Let's say the user wants to build a particular backend for a given platform. For example let's say they want to build coqui for ROCM/hipblas
+
+- The Makefile has targets like `docker-build-coqui` created with `generate-docker-build-target` at the time of writing. Recently added backends may require a new target.
+- At a minimum we need to set the BUILD_TYPE, BASE_IMAGE build-args
+  - Use .github/workflows/backend.yml as a reference it lists the needed args in the `include` job strategy matrix
+  - l4t and cublas also requires the CUDA major and minor version
+- You can pretty print a command like `DOCKER_MAKEFLAGS=-j$(nproc --ignore=1) BUILD_TYPE=hipblas BASE_IMAGE=rocm/dev-ubuntu-24.04:6.4.4 make docker-build-coqui`
+- Unless the user specifies that they want you to run the command, then just print it because not all agent frontends handle long running jobs well and the output may overflow your context
+- The user may say they want to build AMD or ROCM instead of hipblas, or Intel instead of SYCL or NVIDIA insted of l4t or cublas. Ask for confirmation if there is ambiguity.
+- Sometimes the user may need extra parameters to be added to `docker build` (e.g. `--platform` for cross-platform builds or `--progress` to view the full logs), in which case you can generate the `docker build` command directly.

+# Debugging and Rebuilding Backends
+
+When a backend fails at runtime (e.g. a gRPC method error, a Python import error, or a dependency conflict), use this guide to diagnose, fix, and rebuild.
+
+## Architecture Overview
+
+- **Source directory**: `backend/python/<name>/` (or `backend/go/<name>/`, `backend/cpp/<name>/`)
+- **Installed directory**: `backends/<name>/` — this is what LocalAI actually runs. It is populated by `make backends/<name>` which builds a Docker image, exports it, and installs it via `local-ai backends install`.
+- **Virtual environment**: `backends/<name>/venv/` — the installed Python venv (for Python backends). The Python binary is at `backends/<name>/venv/bin/python`.
+
+Editing files in `backend/python/<name>/` does **not** affect the running backend until you rebuild with `make backends/<name>`.
+
+## Diagnosing Failures
+
+### 1. Check the logs
+
+Backend gRPC processes log to LocalAI's stdout/stderr. Look for lines tagged with the backend's model ID:
+
+```
+GRPC stderr id="trl-finetune-127.0.0.1:37335" line="..."
+```
+
+Common error patterns:
+- **"Method not implemented"** — the backend is missing a gRPC method that the Go side calls. The model loader (`pkg/model/initializers.go`) always calls `LoadModel` after `Health`; fine-tuning backends must implement it even as a no-op stub.
+- **Python import errors / `AttributeError`** — usually a dependency version mismatch (e.g. `pyarrow` removing `PyExtensionType`).
+- **"failed to load backend"** — the gRPC process crashed or never started. Check stderr lines for the traceback.
+
+### 2. Test the Python environment directly
+
+You can run the installed venv's Python to check imports without starting the full server:
+
+```bash
+backends/<name>/venv/bin/python -c "import datasets; print(datasets.__version__)"
+```
+
+If `pip` is missing from the venv, bootstrap it:
+
+```bash
+backends/<name>/venv/bin/python -m ensurepip
+```
+
+Then use `backends/<name>/venv/bin/python -m pip install ...` to test fixes in the installed venv before committing them to the source requirements.
+
+### 3. Check upstream dependency constraints
+
+When you hit a dependency conflict, check what the main library expects. For example, TRL's upstream `requirements.txt`:
+
+```
+https://github.com/huggingface/trl/blob/main/requirements.txt
+```
+
+Pin minimum versions in the backend's requirements files to match upstream.
+
+## Common Fixes
+
+### Missing gRPC methods
+
+If the Go side calls a method the backend doesn't implement (e.g. `LoadModel`), add a no-op stub in `backend.py`:
+
+```python
+def LoadModel(self, request, context):
+    """No-op — actual loading happens elsewhere."""
+    return backend_pb2.Result(success=True, message="OK")
+```
+
+The gRPC contract requires `LoadModel` to succeed for the model loader to return a usable client, even if the backend doesn't need upfront model loading.
+
+### Dependency version conflicts
+
+Python backends often break when a transitive dependency releases a breaking change (e.g. `pyarrow` removing `PyExtensionType`). Steps:
+
+1. Identify the broken import in the logs
+2. Test in the installed venv: `backends/<name>/venv/bin/python -c "import <module>"`
+3. Check upstream requirements for version constraints
+4. Update **all** requirements files in `backend/python/<name>/`:
+   - `requirements.txt` — base deps (grpcio, protobuf)
+   - `requirements-cpu.txt` — CPU-specific (includes PyTorch CPU index)
+   - `requirements-cublas12.txt` — CUDA 12
+   - `requirements-cublas13.txt` — CUDA 13
+5. Rebuild: `make backends/<name>`
+
+### PyTorch index conflicts (uv resolver)
+
+The Docker build uses `uv` for pip installs. When `--extra-index-url` points to the PyTorch wheel index, `uv` may refuse to fetch packages like `requests` from PyPI if it finds a different version on the PyTorch index first. Fix this by adding `--index-strategy=unsafe-first-match` to `install.sh`:
+
+```bash
+EXTRA_PIP_INSTALL_FLAGS+=" --upgrade --index-strategy=unsafe-first-match"
+installRequirements
+```
+
+Most Python backends already do this — check `backend/python/transformers/install.sh` or similar for reference.
+
+## Rebuilding
+
+### Rebuild a single backend
+
+```bash
+make backends/<name>
+```
+
+This runs the Docker build (`Dockerfile.python`), exports the image to `backend-images/<name>.tar`, and installs it into `backends/<name>/`. It also rebuilds the `local-ai` Go binary (without extra tags).
+
+**Important**: If you were previously running with `GO_TAGS=auth`, the `make backends/<name>` step will overwrite your binary without that tag. Rebuild the Go binary afterward:
+
+```bash
+GO_TAGS=auth make build
+```
+
+### Rebuild and restart
+
+After rebuilding a backend, you must restart LocalAI for it to pick up the new backend files. The backend gRPC process is spawned on demand when the model is first loaded.
+
+```bash
+# Kill existing process
+kill <pid>
+
+# Restart
+./local-ai run --debug [your flags]
+```
+
+### Quick iteration (skip Docker rebuild)
+
+For fast iteration on a Python backend's `backend.py` without a full Docker rebuild, you can edit the installed copy directly:
+
+```bash
+# Edit the installed copy
+vim backends/<name>/backend.py
+
+# Restart LocalAI to respawn the gRPC process
+```
+
+This is useful for testing but **does not persist** — the next `make backends/<name>` will overwrite it. Always commit fixes to the source in `backend/python/<name>/`.
+
+## Verification
+
+After fixing and rebuilding:
+
+1. Start LocalAI and confirm the backend registers: look for `Registering backend name="<name>"` in the logs
+2. Trigger the operation that failed (e.g. start a fine-tuning job)
+3. Watch the GRPC stderr/stdout lines for the backend's model ID
+4. Confirm no errors in the traceback

+- Test llama.cpp backend compilation: `make backends/llama-cpp`
+- The backend is built as part of the main build process
+- Check `backend/cpp/llama-cpp/Makefile` for build configuration
+
+## Architecture
+
+- **grpc-server.cpp**: gRPC server implementation, adapts HTTP server patterns to gRPC
+- Uses shared server infrastructure: `server-context.cpp`, `server-task.cpp`, `server-queue.cpp`, `server-common.cpp`
+- The gRPC server mirrors the HTTP server's functionality but uses gRPC instead of HTTP
+
+## Common Issues When Updating llama.cpp
+
+When fixing compilation errors after upstream changes:
+1. Check how `server.cpp` (HTTP server) handles the same change
+2. Look for new public APIs or getter methods
+3. Store copies of needed data instead of accessing private members
+4. Update function calls to match new signatures
+5. Test with `make backends/llama-cpp`
+
+## Key Differences from HTTP Server
+
+- gRPC uses `BackendServiceImpl` class with gRPC service methods
+- HTTP server uses `server_routes` with HTTP handlers
+- Both use the same `server_context` and task queue infrastructure
+- gRPC methods: `LoadModel`, `Predict`, `PredictStream`, `Embedding`, `Rerank`, `TokenizeString`, `GetMetrics`, `Health`
+
+## Tool Call Parsing Maintenance
+
+When working on JSON/XML tool call parsing functionality, always check llama.cpp for reference implementation and updates:
+
+### Checking for XML Parsing Changes
+
+1. **Review XML Format Definitions**: Check `llama.cpp/common/chat-parser-xml-toolcall.h` for `xml_tool_call_format` struct changes
+2. **Review Parsing Logic**: Check `llama.cpp/common/chat-parser-xml-toolcall.cpp` for parsing algorithm updates
+3. **Review Format Presets**: Check `llama.cpp/common/chat-parser.cpp` for new XML format presets (search for `xml_tool_call_format form`)
+4. **Review Model Lists**: Check `llama.cpp/common/chat.h` for `COMMON_CHAT_FORMAT_*` enum values that use XML parsing:
+   - `COMMON_CHAT_FORMAT_GLM_4_5`
+   - `COMMON_CHAT_FORMAT_MINIMAX_M2`
+   - `COMMON_CHAT_FORMAT_KIMI_K2`
+   - `COMMON_CHAT_FORMAT_QWEN3_CODER_XML`
+   - `COMMON_CHAT_FORMAT_APRIEL_1_5`
+   - `COMMON_CHAT_FORMAT_XIAOMI_MIMO`
+   - Any new formats added
+
+### Model Configuration Options
+
+Always check `llama.cpp` for new model configuration options that should be supported in LocalAI:
+
+1. **Check Server Context**: Review `llama.cpp/tools/server/server-context.cpp` for new parameters
+2. **Check Chat Params**: Review `llama.cpp/common/chat.h` for `common_chat_params` struct changes
+3. **Check Server Options**: Review `llama.cpp/tools/server/server.cpp` for command-line argument changes
+4. **Examples of options to check**:
+   - `ctx_shift` - Context shifting support
+   - `parallel_tool_calls` - Parallel tool calling
+   - `reasoning_format` - Reasoning format options
+   - Any new flags or parameters
+
+### Implementation Guidelines
+
+1. **Feature Parity**: Always aim for feature parity with llama.cpp's implementation
+2. **Test Coverage**: Add tests for new features matching llama.cpp's behavior
+3. **Documentation**: Update relevant documentation when adding new formats or options
+4. **Backward Compatibility**: Ensure changes don't break existing functionality
+
+### Files to Monitor
+
+- `llama.cpp/common/chat-parser-xml-toolcall.h` - Format definitions
+- `llama.cpp/common/chat-parser-xml-toolcall.cpp` - Parsing logic
+- `llama.cpp/common/chat-parser.cpp` - Format presets and model-specific handlers
+- `llama.cpp/common/chat.h` - Format enums and parameter structures
+- `llama.cpp/tools/server/server-context.cpp` - Server configuration options

+# Testing MCP Apps (Interactive Tool UIs)
+
+MCP Apps is an extension to MCP where tools declare interactive HTML UIs via `_meta.ui.resourceUri`. When the LLM calls such a tool, the UI renders the app in a sandboxed iframe inline in the chat. The app communicates bidirectionally with the host via `postMessage` (JSON-RPC) and can call server tools, send messages, and update model context.
+
+Spec: https://modelcontextprotocol.io/extensions/apps/overview
+
+## Quick Start: Run a Test MCP App Server
+
+The `@modelcontextprotocol/server-basic-react` npm package is a ready-to-use test server that exposes a `get-time` tool with an interactive React clock UI. It requires Node >= 20, so run it in Docker:
+
+```bash
+docker run -d --name mcp-app-test -p 3001:3001 node:22-slim \
+  sh -c 'npx -y @modelcontextprotocol/server-basic-react'
+```
+
+Wait ~10 seconds for it to start, then verify:
+
+```bash
+# Check it's running
+docker logs mcp-app-test
+# Expected: "MCP server listening on http://localhost:3001/mcp"
+
+# Verify MCP protocol works
+curl -s -X POST http://localhost:3001/mcp \
+  -H 'Content-Type: application/json' \
+  -H 'Accept: application/json, text/event-stream' \
+  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}'
+
+# List tools — should show get-time with _meta.ui.resourceUri
+curl -s -X POST http://localhost:3001/mcp \
+  -H 'Content-Type: application/json' \
+  -H 'Accept: application/json, text/event-stream' \
+  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'
+```
+
+The `tools/list` response should contain:
+```json
+{
+  "name": "get-time",
+  "_meta": {
+    "ui": { "resourceUri": "ui://get-time/mcp-app.html" }
+  }
+}
+```
+
+## Testing in LocalAI's UI
+
+1. Make sure LocalAI is running (e.g. `http://localhost:8080`)
+2. Build the React UI: `cd core/http/react-ui && npm install && npm run build`
+3. Open the Chat page in your browser
+4. Click **"Client MCP"** in the chat header
+5. Add a new client MCP server:
+   - **URL**: `http://localhost:3001/mcp`
+   - **Use CORS proxy**: enabled (default) — required because the browser can't hit `localhost:3001` directly due to CORS; LocalAI's proxy at `/api/cors-proxy` handles it
+6. The server should connect and discover the `get-time` tool
+7. Select a model and send: **"What time is it?"**
+8. The LLM should call the `get-time` tool
+9. The tool result should render the interactive React clock app in an iframe as a standalone chat message (not inside the collapsed activity group)
+
+## What to Verify
+
+- [ ] Tool appears in the connected tools list (not filtered — `get-time` is callable by the LLM)
+- [ ] The iframe renders as a standalone chat message with a puzzle-piece icon
+- [ ] The app loads and is interactive (clock UI, buttons work)
+- [ ] No "Reconnect to MCP server" overlay (connection is live)
+- [ ] Console logs show bidirectional communication:
+  - `tools/call` messages from app to host (app calling server tools)
+  - `ui/message` notifications (app sending messages)
+- [ ] After the app renders, the LLM continues and produces a text response with the time
+- [ ] Non-UI tools continue to work normally (text-only results)
+- [ ] Page reload shows the HTML statically with a reconnect overlay until you reconnect
+
+## Console Log Patterns
+
+Healthy bidirectional communication looks like:
+
+```
+Parsed message { jsonrpc: "2.0", id: N, result: {...} }     // Bridge init
+get-time result: { content: [...] }                          // Tool result received
+Calling get-time tool...                                     // App calls tool
+Sending message { method: "tools/call", ... }                // App -> host -> server
+Parsed message { jsonrpc: "2.0", id: N, result: {...} }     // Server response
+Sending message text to Host: ...                            // App sends message
+Sending message { method: "ui/message", ... }                // Message notification
+Message accepted                                             // Host acknowledged
+```
+
+Benign warnings to ignore:
+- `Source map error: ... about:srcdoc` — browser devtools can't find source maps for srcdoc iframes
+- `Ignoring message from unknown source` — duplicate postMessage from iframe navigation
+- `notifications/cancelled` — app cleaning up previous requests
+
+## Architecture Notes
+
+- **No server-side changes needed** — the MCP App protocol runs entirely in the browser
+- `PostMessageTransport` wraps `window.postMessage` between host and `srcdoc` iframe
+- `AppBridge` (from `@modelcontextprotocol/ext-apps`) auto-forwards `tools/call`, `resources/read`, `resources/list` from the app to the MCP server via the host's `Client`
+- The iframe uses `sandbox="allow-scripts allow-forms"` (no `allow-same-origin`) — opaque origin, no access to host cookies/DOM/localStorage
+- App-only tools (`_meta.ui.visibility: "app-only"`) are filtered from the LLM's tool list but remain callable by the app iframe
+
+## Key Files
+
+- `core/http/react-ui/src/components/MCPAppFrame.jsx` — iframe + AppBridge component
+- `core/http/react-ui/src/hooks/useMCPClient.js` — MCP client hook with app UI helpers (`hasAppUI`, `getAppResource`, `getClientForTool`, `getToolDefinition`)
+- `core/http/react-ui/src/hooks/useChat.js` — agentic loop, attaches `appUI` to tool_result messages
+- `core/http/react-ui/src/pages/Chat.jsx` — renders MCPAppFrame as standalone chat messages
+
+## Other Test Servers
+
+The `@modelcontextprotocol/ext-apps` repo has many example servers:
+- `@modelcontextprotocol/server-basic-react` — simple clock (React)
+- More examples at https://github.com/modelcontextprotocol/ext-apps/tree/main/examples
+
+All examples support both stdio and HTTP transport. Run without `--stdio` for HTTP mode on port 3001.
+
+## Cleanup
+
+```bash
+docker rm -f mcp-app-test
+```

-# Build and testing
-
-Building and testing the project depends on the components involved and the platform where development is taking place. Due to the amount of context required it's usually best not to try building or testing the project unless the user requests it. If you must build the project then inspect the Makefile in the project root and the Makefiles of any backends that are effected by changes you are making. In addition the workflows in .github/workflows can be used as a reference when it is unclear how to build or test a component. The primary Makefile contains targets for building inside or outside Docker, if the user has not previously specified a preference then ask which they would like to use.
-
-## Building a specified backend
-
-Let's say the user wants to build a particular backend for a given platform. For example let's say they want to build bark for ROCM/hipblas
-
-- The Makefile has targets like `docker-build-bark` created with `generate-docker-build-target` at the time of writing. Recently added backends may require a new target.
-- At a minimum we need to set the BUILD_TYPE, BASE_IMAGE build-args
-  - Use .github/workflows/backend.yml as a reference it lists the needed args in the `include` job strategy matrix
-  - l4t and cublas also requires the CUDA major and minor version
-- You can pretty print a command like `DOCKER_MAKEFLAGS=-j$(nproc --ignore=1) BUILD_TYPE=hipblas BASE_IMAGE=rocm/dev-ubuntu-24.04:6.4.4 make docker-build-bark`
-- Unless the user specifies that they want you to run the command, then just print it because not all agent frontends handle long running jobs well and the output may overflow your context
-- The user may say they want to build AMD or ROCM instead of hipblas, or Intel instead of SYCL or NVIDIA insted of l4t or cublas. Ask for confirmation if there is ambiguity.
-- Sometimes the user may need extra parameters to be added to `docker build` (e.g. `--platform` for cross-platform builds or `--progress` to view the full logs), in which case you can generate the `docker build` command directly.
-
-## Adding a New Backend
-
-When adding a new backend to LocalAI, you need to update several files to ensure the backend is properly built, tested, and registered. Here's a step-by-step guide based on the pattern used for adding backends like `moonshine`:
-
-### 1. Create Backend Directory Structure
-
-Create the backend directory under the appropriate location:
-- **Python backends**: `backend/python/<backend-name>/`
-- **Go backends**: `backend/go/<backend-name>/`
-- **C++ backends**: `backend/cpp/<backend-name>/`
-
-For Python backends, you'll typically need:
-- `backend.py` - Main gRPC server implementation
-- `Makefile` - Build configuration
-- `install.sh` - Installation script for dependencies
-- `protogen.sh` - Protocol buffer generation script
-- `requirements.txt` - Python dependencies
-- `run.sh` - Runtime script
-- `test.py` / `test.sh` - Test files
-
-### 2. Add Build Configurations to `.github/workflows/backend.yml`
-
-Add build matrix entries for each platform/GPU type you want to support. Look at similar backends (e.g., `chatterbox`, `faster-whisper`) for reference.
-
-**Placement in file:**
-- CPU builds: Add after other CPU builds (e.g., after `cpu-chatterbox`)
-- CUDA 12 builds: Add after other CUDA 12 builds (e.g., after `gpu-nvidia-cuda-12-chatterbox`)
-- CUDA 13 builds: Add after other CUDA 13 builds (e.g., after `gpu-nvidia-cuda-13-chatterbox`)
-
-**Additional build types you may need:**
-- ROCm/HIP: Use `build-type: 'hipblas'` with `base-image: "rocm/dev-ubuntu-24.04:6.4.4"`
-- Intel/SYCL: Use `build-type: 'intel'` or `build-type: 'sycl_f16'`/`sycl_f32` with `base-image: "intel/oneapi-basekit:2025.3.0-0-devel-ubuntu24.04"`
-- L4T (ARM): Use `build-type: 'l4t'` with `platforms: 'linux/arm64'` and `runs-on: 'ubuntu-24.04-arm'`
-
-### 3. Add Backend Metadata to `backend/index.yaml`
-
-**Step 3a: Add Meta Definition**
-
-Add a YAML anchor definition in the `## metas` section (around line 2-300). Look for similar backends to use as a template such as `diffusers` or `chatterbox`
-
-**Step 3b: Add Image Entries**
-
-Add image entries at the end of the file, following the pattern of similar backends such as `diffusers` or `chatterbox`. Include both `latest` (production) and `master` (development) tags.
-
-### 4. Update the Makefile
-
-The Makefile needs to be updated in several places to support building and testing the new backend:
-
-**Step 4a: Add to `.NOTPARALLEL`**
-
-Add `backends/<backend-name>` to the `.NOTPARALLEL` line (around line 2) to prevent parallel execution conflicts:
-
-```makefile
-.NOTPARALLEL: ... backends/<backend-name>
-```
-
-**Step 4b: Add to `prepare-test-extra`**
-
-Add the backend to the `prepare-test-extra` target (around line 312) to prepare it for testing:
-
-```makefile
-prepare-test-extra: protogen-python
-	...
-	$(MAKE) -C backend/python/<backend-name>
-```
-
-**Step 4c: Add to `test-extra`**
-
-Add the backend to the `test-extra` target (around line 319) to run its tests:
-
-```makefile
-test-extra: prepare-test-extra
-	...
-	$(MAKE) -C backend/python/<backend-name> test
-```
-
-**Step 4d: Add Backend Definition**
-
-Add a backend definition variable in the backend definitions section (around line 428-457). The format depends on the backend type:
-
-**For Python backends with root context** (like `faster-whisper`, `bark`):
-```makefile
-BACKEND_<BACKEND_NAME> = <backend-name>|python|.|false|true
-```
-
-**For Python backends with `./backend` context** (like `chatterbox`, `moonshine`):
-```makefile
-BACKEND_<BACKEND_NAME> = <backend-name>|python|./backend|false|true
-```
-
-**For Go backends**:
-```makefile
-BACKEND_<BACKEND_NAME> = <backend-name>|golang|.|false|true
-```
-
-**Step 4e: Generate Docker Build Target**
-
-Add an eval call to generate the docker-build target (around line 480-501):
-
-```makefile
-$(eval $(call generate-docker-build-target,$(BACKEND_<BACKEND_NAME>)))
-```
-
-**Step 4f: Add to `docker-build-backends`**
-
-Add `docker-build-<backend-name>` to the `docker-build-backends` target (around line 507):
-
-```makefile
-docker-build-backends: ... docker-build-<backend-name>
-```
-
-**Determining the Context:**
-
-- If the backend is in `backend/python/<backend-name>/` and uses `./backend` as context in the workflow file, use `./backend` context
-- If the backend is in `backend/python/<backend-name>/` but uses `.` as context in the workflow file, use `.` context
-- Check similar backends to determine the correct context
-
-### 5. Verification Checklist
-
-After adding a new backend, verify:
-
-- [ ] Backend directory structure is complete with all necessary files
-- [ ] Build configurations added to `.github/workflows/backend.yml` for all desired platforms
-- [ ] Meta definition added to `backend/index.yaml` in the `## metas` section
-- [ ] Image entries added to `backend/index.yaml` for all build variants (latest + development)
-- [ ] Tag suffixes match between workflow file and index.yaml
-- [ ] Makefile updated with all 6 required changes (`.NOTPARALLEL`, `prepare-test-extra`, `test-extra`, backend definition, docker-build target eval, `docker-build-backends`)
-- [ ] No YAML syntax errors (check with linter)
-- [ ] No Makefile syntax errors (check with linter)
-- [ ] Follows the same pattern as similar backends (e.g., if it's a transcription backend, follow `faster-whisper` pattern)
-
-### 6. Example: Adding a Python Backend
-
-For reference, when `moonshine` was added:
-- **Files created**: `backend/python/moonshine/{backend.py, Makefile, install.sh, protogen.sh, requirements.txt, run.sh, test.py, test.sh}`
-- **Workflow entries**: 3 build configurations (CPU, CUDA 12, CUDA 13)
-- **Index entries**: 1 meta definition + 6 image entries (cpu, cuda12, cuda13 × latest/development)
-- **Makefile updates**: 
-  - Added to `.NOTPARALLEL` line
-  - Added to `prepare-test-extra` and `test-extra` targets
-  - Added `BACKEND_MOONSHINE = moonshine|python|./backend|false|true`
-  - Added eval for docker-build target generation
-  - Added `docker-build-moonshine` to `docker-build-backends`
-
-# Coding style
-
-- The project has the following .editorconfig
-
-```
-root = true
-
-[*]
-indent_style = space
-indent_size = 2
-end_of_line = lf
-charset = utf-8
-trim_trailing_whitespace = true
-insert_final_newline = true

-
-[*.js]
-indent_size = 2
-
-[*.yaml]
-indent_size = 2
-
-[*.md]
-trim_trailing_whitespace = false
-```
-
-- Use comments sparingly to explain why code does something, not what it does. Comments are there to add context that would be difficult to deduce from reading the code.
-- Prefer modern Go e.g. use `any` not `interface{}`
-
-# Logging
-
-Use `github.com/mudler/xlog` for logging which has the same API as slog.
-
-# llama.cpp Backend
-
-The llama.cpp backend (`backend/cpp/llama-cpp/grpc-server.cpp`) is a gRPC adaptation of the upstream HTTP server (`llama.cpp/tools/server/server.cpp`). It uses the same underlying server infrastructure from `llama.cpp/tools/server/server-context.cpp`.
-
-## Building and Testing
-
-- Test llama.cpp backend compilation: `make backends/llama-cpp`
-- The backend is built as part of the main build process
-- Check `backend/cpp/llama-cpp/Makefile` for build configuration
-
-## Architecture
-
-- **grpc-server.cpp**: gRPC server implementation, adapts HTTP server patterns to gRPC
-- Uses shared server infrastructure: `server-context.cpp`, `server-task.cpp`, `server-queue.cpp`, `server-common.cpp`
-- The gRPC server mirrors the HTTP server's functionality but uses gRPC instead of HTTP
-
-## Common Issues When Updating llama.cpp
-
-When fixing compilation errors after upstream changes:
-1. Check how `server.cpp` (HTTP server) handles the same change
-2. Look for new public APIs or getter methods
-3. Store copies of needed data instead of accessing private members
-4. Update function calls to match new signatures
-5. Test with `make backends/llama-cpp`
-
-## Key Differences from HTTP Server
-
-- gRPC uses `BackendServiceImpl` class with gRPC service methods
-- HTTP server uses `server_routes` with HTTP handlers
-- Both use the same `server_context` and task queue infrastructure
-- gRPC methods: `LoadModel`, `Predict`, `PredictStream`, `Embedding`, `Rerank`, `TokenizeString`, `GetMetrics`, `Health`
-
-## Tool Call Parsing Maintenance
-
-When working on JSON/XML tool call parsing functionality, always check llama.cpp for reference implementation and updates:
-
-### Checking for XML Parsing Changes
-
-1. **Review XML Format Definitions**: Check `llama.cpp/common/chat-parser-xml-toolcall.h` for `xml_tool_call_format` struct changes
-2. **Review Parsing Logic**: Check `llama.cpp/common/chat-parser-xml-toolcall.cpp` for parsing algorithm updates
-3. **Review Format Presets**: Check `llama.cpp/common/chat-parser.cpp` for new XML format presets (search for `xml_tool_call_format form`)
-4. **Review Model Lists**: Check `llama.cpp/common/chat.h` for `COMMON_CHAT_FORMAT_*` enum values that use XML parsing:
-   - `COMMON_CHAT_FORMAT_GLM_4_5`
-   - `COMMON_CHAT_FORMAT_MINIMAX_M2`
-   - `COMMON_CHAT_FORMAT_KIMI_K2`
-   - `COMMON_CHAT_FORMAT_QWEN3_CODER_XML`
-   - `COMMON_CHAT_FORMAT_APRIEL_1_5`
-   - `COMMON_CHAT_FORMAT_XIAOMI_MIMO`
-   - Any new formats added
-
-### Model Configuration Options
-
-Always check `llama.cpp` for new model configuration options that should be supported in LocalAI:
-
-1. **Check Server Context**: Review `llama.cpp/tools/server/server-context.cpp` for new parameters
-2. **Check Chat Params**: Review `llama.cpp/common/chat.h` for `common_chat_params` struct changes
-3. **Check Server Options**: Review `llama.cpp/tools/server/server.cpp` for command-line argument changes
-4. **Examples of options to check**:
-   - `ctx_shift` - Context shifting support
-   - `parallel_tool_calls` - Parallel tool calling
-   - `reasoning_format` - Reasoning format options
-   - Any new flags or parameters
-
-### Implementation Guidelines
-
-1. **Feature Parity**: Always aim for feature parity with llama.cpp's implementation
-2. **Test Coverage**: Add tests for new features matching llama.cpp's behavior
-3. **Documentation**: Update relevant documentation when adding new formats or options
-4. **Backward Compatibility**: Ensure changes don't break existing functionality
-
-### Files to Monitor
-
-- `llama.cpp/common/chat-parser-xml-toolcall.h` - Format definitions
-- `llama.cpp/common/chat-parser-xml-toolcall.cpp` - Parsing logic
-- `llama.cpp/common/chat-parser.cpp` - Format presets and model-specific handlers
-- `llama.cpp/common/chat.h` - Format enums and parameter structures
-- `llama.cpp/tools/server/server-context.cpp` - Server configuration options

+- **Go style**: Prefer `any` over `interface{}`
+- **Comments**: Explain *why*, not *what*
+- **Docs**: Update `docs/content/` when adding features or changing config
+- **Build**: Inspect `Makefile` and `.github/workflows/` — ask the user before running long builds
+- **UI**: The active UI is the React app in `core/http/react-ui/`. The older Alpine.js/HTML UI in `core/http/static/` is pending deprecation — all new UI work goes in the React UI

+
+### Setting up the Development Environment
+
+1. **Clone the repository:**
+
+   ```bash
+   git clone https://github.com/mudler/LocalAI.git
+   cd LocalAI
+   ```
+
+2. **Build LocalAI:**
+
+   ```bash
+   make build
+   ```
+
+   This runs protobuf generation, installs Go tools, builds the React UI, and compiles the `local-ai` binary. Key build variables you can set:
+
+   | Variable | Description | Example |
+   |---|---|---|
+   | `BUILD_TYPE` | GPU/accelerator type (`cublas`, `hipblas`, `intel`, ``) | `BUILD_TYPE=cublas make build` |
+   | `GO_TAGS` | Additional Go build tags | `GO_TAGS=debug make build` |
+   | `CUDA_MAJOR_VERSION` | CUDA major version (default: `13`) | `CUDA_MAJOR_VERSION=12` |
+
+3. **Run LocalAI:**
+
+   ```bash
+   ./local-ai
+   ```
+
+4. **Development mode with live reload:**
+
+   ```bash
+   make build-dev
+   ```
+
+   This installs [`air`](https://github.com/air-verse/air) automatically and watches for file changes, rebuilding and restarting the server on each save.
+
+5. **Containerized build** (no local toolchain needed):
+
+   ```bash
+   make docker
+   ```
+
+   For GPU-specific Docker builds, see the `docker-build-*` targets in the Makefile and refer to [CLAUDE.md](CLAUDE.md) for detailed backend build instructions.
+
+### Environment Variables
+
+LocalAI is configured primarily through environment variables (or equivalent CLI flags). The most useful ones for development are:
+
+| Variable | Description | Default |
+|---|---|---|
+| `LOCALAI_DEBUG` | Enable debug mode | `false` |
+| `LOCALAI_LOG_LEVEL` | Log verbosity (`error`, `warn`, `info`, `debug`, `trace`) | — |
+| `LOCALAI_LOG_FORMAT` | Log format (`default`, `text`, `json`) | `default` |
+| `LOCALAI_MODELS_PATH` | Path to model files | `./models` |
+| `LOCALAI_BACKENDS_PATH` | Path to backend binaries | `./backends` |
+| `LOCALAI_CONFIG_DIR` | Directory for dynamic config files (API keys, external backends) | `./configuration` |
+| `LOCALAI_THREADS` | Number of threads for inference | — |
+| `LOCALAI_ADDRESS` | Bind address for the API server | `:8080` |
+| `LOCALAI_API_KEY` | API key(s) for authentication | — |
+| `LOCALAI_CORS` | Enable CORS | `false` |
+| `LOCALAI_DISABLE_WEBUI` | Disable the web UI | `false` |
+
+See `core/cli/run.go` for the full list of supported environment variables.

-### Creating a Pull Request (PR)
+### Development Workflow
+
+#### Branch naming conventions
+
+Use a descriptive branch name that indicates the type and scope of the change:
+
+- `feature/<short-description>` — new functionality
+- `fix/<short-description>` — bug fixes
+- `docs/<short-description>` — documentation changes
+- `refactor/<short-description>` — code refactoring
+
+#### Commit messages
+
+- Use a short, imperative subject line (e.g., "feat: add whisper backend support", not "Added whisper backend support")
+- Keep the subject under 72 characters
+- Use the body to explain **why** the change was made when the subject alone is not sufficient
+- Use [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/)
+
+#### Creating a Pull Request (PR)
+
+Before jumping into a PR for a massive feature or big change, it is preferred to discuss it first via an issue.
 
 1. Fork the repository.
-2. Create a new branch with a descriptive name: `git checkout -b [branch name]`
-3. Make your changes and commit them.
-4. Push the changes to your fork: `git push origin [branch name]`
-5. Create a new pull request from your branch to the main project's `main` or `master` branch.
-6. Provide a clear description of your changes in the pull request.
-7. Make any requested changes during the review process.
-8. Once your PR is approved, it will be merged into the main project.
+2. Create a new branch: `git checkout -b feature/my-change`
+3. Make your changes, keeping commits focused and atomic.
+4. Run tests locally before pushing (see [Testing](#testing) below).
+5. Push to your fork: `git push origin feature/my-change`
+6. Open a pull request against the `master` branch.
+7. Fill in the PR description with:
+   - What the change does and why
+   - How it was tested
+   - Any breaking changes or migration steps
+8. Respond to review feedback promptly. Push follow-up commits rather than force-pushing amended commits so reviewers can see incremental changes.
+9. Once approved, a maintainer will merge your PR.
 
 ## Coding Guidelines
 
-- No specific coding guidelines at the moment. Please make sure the code can be tested. The most popular lint tools like [`golangci-lint`](https://golangci-lint.run) can help you here.
+This project uses an [`.editorconfig`](.editorconfig) file to define formatting standards (indentation, line endings, charset, etc.). Please configure your editor to respect it.
+
+For AI-assisted development, see [`CLAUDE.md`](CLAUDE.md) for agent-specific guidelines including build instructions and backend architecture details.
+
+### General Principles
+
+- Write code that can be tested. All new features and bug fixes should include test coverage.
+- Use comments sparingly to explain **why** code does something, not **what** it does. Comments should add context that would be difficult to deduce from reading the code alone.
+- Keep changes focused. Avoid unrelated refactors, formatting changes, or feature additions in the same PR.
+
+### Go Code
+
+- Prefer modern Go idioms — for example, use `any` instead of `interface{}`.
+- Use [`golangci-lint`](https://golangci-lint.run) to catch common issues before submitting a PR.
+- Use [`github.com/mudler/xlog`](https://github.com/mudler/xlog) for logging (same API as `slog`). Do not use `fmt.Println` or the standard `log` package for operational logging.
+- Use tab indentation for Go files (as defined in `.editorconfig`).
+
+### Python Code
+
+- Use 4-space indentation (as defined in `.editorconfig`).
+- Include a `requirements.txt` for any new dependencies.
+
+### Code Review
+
+- All contributions go through code review via pull requests.
+- Reviewers will check for correctness, test coverage, adherence to these guidelines, and clarity of intent.
+- Be responsive to review feedback and keep discussions constructive.
 
 ## Testing
 
-`make test` cannot handle all the model now. Please be sure to add a test case for the new features or the part was changed.
+All new features and bug fixes should include test coverage. The project uses [Ginkgo](https://onsi.github.io/ginkgo/) as its test framework.
 
-### Running AIO tests
+### Running unit tests
 
-All-In-One images has a set of tests that automatically verifies that most of the endpoints works correctly, a flow can be :
+```bash
+make test
+```
+
+This downloads test model fixtures, runs protobuf generation, and executes the full test suite including llama-gguf, TTS, and stable-diffusion tests. Note: some tests require model files to be downloaded, so the first run may take longer.
+
+To run tests for a specific package:
+
+```bash
+go test ./core/config/...
+go test ./pkg/model/...
+```
+
+To run a specific test by name using Ginkgo's `--focus` flag:
+
+```bash
+go run github.com/onsi/ginkgo/v2/ginkgo --focus="should load a model" -v -r ./core/
+```
+
+### Running end-to-end tests
+
+The e2e tests run LocalAI in a Docker container and exercise the API:
+
+```bash
+make test-e2e
+```
+
+### Running E2E container tests
+
+These tests build a standard LocalAI Docker image and run it with pre-configured model configs to verify that most endpoints work correctly:
 
 ```bash
 # Build the LocalAI docker image
-make DOCKER_IMAGE=local-ai docker
+make docker-build-e2e
 
-# Build the corresponding AIO image
-BASE_IMAGE=local-ai DOCKER_AIO_IMAGE=local-ai-aio:test make docker-aio
+# Run the e2e tests (uses model configs from tests/e2e-aio/models/)
+make e2e-aio
+```
 
-# Run the AIO e2e tests
-LOCALAI_IMAGE_TAG=test LOCALAI_IMAGE=local-ai-aio make run-e2e-aio
+### Testing backends
+
+To prepare and test extra (Python) backends:
+
+```bash
+make prepare-test-extra   # build Python backends for testing
+make test-extra           # run backend-specific tests
 ```

 **LocalAI** is the free, Open Source OpenAI alternative. LocalAI act as a drop-in replacement REST API that's compatible with OpenAI (Elevenlabs, Anthropic... ) API specifications for local AI inferencing. It allows you to run LLMs, generate images, audio (and not only) locally or on-prem with consumer grade hardware, supporting multiple model families. Does not require GPU. It is created and maintained by [Ettore Di Giacinto](https://github.com/mudler).
