+## Importer integration
+
+When you add a new backend, you MUST also make it importable via the model import form (`/import-model`). The import form dropdown is sourced dynamically from `GET /backends/known` — it reads the importer registry at `core/gallery/importers/importers.go`, so the steps below are the ONLY way to make your backend show up.
+
+Required steps:
+
+1. **If your backend has unambiguous detection signals** (unique file extension, HF `pipeline_tag`, unique repo name pattern, unique artefact like `modules.json`):
+   - Create an importer file at `core/gallery/importers/<backend>.go` following the Match/Import pattern in `llama-cpp.go`.
+   - Register it in `importers.go:defaultImporters` in **specificity order** — more specific detectors must appear BEFORE more generic ones (e.g. `sentencetransformers` before `transformers`, `stablediffusion-ggml` before `llama-cpp`, `vllm-omni` before `vllm`). First match wins.
+2. **If your backend is a drop-in replacement** (same artefacts as another backend, e.g. `ik-llama-cpp` and `turboquant` both consume GGUF the same way `llama-cpp` does):
+   - Do NOT create a new importer. Extend the existing importer's `Import()` to swap the emitted `backend:` field when `preferences.backend` matches. See `llama-cpp.go` for the pattern.
+3. **If your backend has no reliable auto-detect signal** (preference-only — e.g. `sglang`, `tinygrad`, `whisperx`):
+   - Do NOT create an importer. Instead add the backend name to the curated pref-only slice in `core/http/endpoints/localai/backend.go` that feeds `/backends/known`. A single line addition.
+4. **Always** add a table-driven test in `core/gallery/importers/importers_test.go` (Ginkgo/Gomega):
+   - Use a real public HuggingFace repo URI as the test fixture (existing tests already hit the live HF API — follow that pattern).
+   - Cover detection (auto-match without preferences), preference-override (explicit `backend:` in preferences wins), and — if the backend's modality has a common `pipeline_tag` but ambiguous artefacts — an ambiguity test asserting `errors.Is(err, importers.ErrAmbiguousImport)`.
+
+Rules of thumb:
+
+- When in doubt, lean pref-only. A wrong auto-detect is worse than a forced preference.
+- Never silently emit a modality mismatch (e.g. emit `llama-cpp` for a TTS repo because `.gguf` is present). Return `ErrAmbiguousImport` instead.
+- Registration order is the single most common source of bugs. Check by running `go test ./core/gallery/importers/...` — the existing suite will fail if you've shadowed a pre-existing detector.

 This guide covers how to add new API endpoints and properly integrate them with the auth/permissions system.
 
+> **Before you ship a new endpoint or capability surface**, re-read the [checklist at the bottom of this file](#checklist). LocalAI advertises its feature surface in several independent places — miss any one of them and clients/admins/UI won't know the endpoint exists.
+
 ## Architecture overview
 
 Authentication and authorization flow through three layers:
@@ -234,6 +236,66 @@ Use these HTTP status codes:
 
 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`.
 
+## Advertising surfaces — where to register a new capability
+
+Beyond routing and auth, LocalAI publishes its capability surface in **four independent places**. When you add an endpoint — especially one introducing a net-new capability like a new media type or a new auth-gated feature — you must update every relevant surface. These aren't optional: missing them means the endpoint works but is invisible to clients, admins, and the UI.
+
+### 1. Swagger `@Tags` annotation (mandatory)
+
+Every handler needs a swagger block so the endpoint appears in `/swagger/index.html` and in the `/api/instructions` output. The `@Tags` value is what groups the endpoint into a capability area:
+
+```go
+// MyEndpoint does X.
+// @Summary Do X.
+// @Tags my-capability
+// @Param request body schema.MyRequest true "payload"
+// @Success 200 {object} schema.MyResponse "Response"
+// @Router /v1/my-endpoint [post]
+func MyEndpoint(...) echo.HandlerFunc { ... }
+```
+
+Use an existing tag when the endpoint extends an existing area (e.g. `audio`, `images`, `face-recognition`). Create a new tag only when the endpoint introduces a genuinely new capability surface — and in that case, also register it in step 2.
+
+After adding endpoints, regenerate the embedded spec so the runtime serves it:
+
+```bash
+make protogen-go         # ensures gRPC codegen is fresh first
+make swagger             # regenerates swagger/swagger.json
+```
+
+### 2. `/api/instructions` registry (for new capability areas)
+
+`core/http/endpoints/localai/api_instructions.go` defines `instructionDefs` — a lightweight, machine-readable index of capability areas that groups swagger endpoints by tag. It's the primary discovery surface for agents and SDKs ("what can this server do?").
+
+**When to update:** only when adding a new capability area (a new swagger tag). Existing-tag additions automatically surface without any change here.
+
+Add an entry to `instructionDefs`:
+
+```go
+{
+    Name:        "my-capability",             // URL segment at /api/instructions/my-capability
+    Description: "Short sentence describing the capability",
+    Tags:        []string{"my-capability"},   // must match swagger @Tags
+    Intro:       "Optional gotcha/context that isn't in the swagger descriptions (caveats, defaults, cross-references to other endpoints).",
+},
+```
+
+Also bump the expected-length count in `api_instructions_test.go` and add the name to the `ContainElements` assertion.
+
+### 3. `capabilities.js` symbol (for new model-config FLAG_* flags)
+
+If your feature needs a new `FLAG_*` usecase flag in `core/config/model_config.go` (so users can filter gallery models by it, and so `/v1/models` surfaces it), also declare the matching symbol in `core/http/react-ui/src/utils/capabilities.js`:
+
+```js
+export const CAP_MY_CAPABILITY = 'FLAG_MY_CAPABILITY'
+```
+
+React pages that want to filter the ModelSelector by capability import this symbol. Declare it even if you're not building the UI page yet — the declaration keeps the Go/JS vocabularies in sync.
+
+### 4. `docs/content/` (user-facing documentation)
+
+A new capability deserves its own page under `docs/content/features/`, plus cross-links from related features and an entry in `docs/content/whats-new.md`. See the pattern used by `face-recognition.md` / `object-detection.md`.

+## Go tests
+
+All Go tests — including backend tests — must use [Ginkgo](https://onsi.github.io/ginkgo/) (v2) with Gomega matchers, not the stdlib `testing` package with `t.Run` / `t.Errorf`. A test file should register a suite with `RegisterFailHandler(Fail)` in a `TestXxx(t *testing.T)` bootstrap and use `Describe`/`Context`/`It` blocks for the actual cases. Look at any existing `*_test.go` under `core/` or `pkg/` for a template.
+
+Do not mix styles within a package. If you are extending tests in a package that already uses Ginkgo, keep using Ginkgo. If you find stdlib-style Go tests in the tree, treat them as tech debt to be migrated rather than as a pattern to follow.

 ## Documentation
 
 The project documentation is located in `docs/content`. When adding new features or changing existing functionality, it is crucial to update the documentation to reflect these changes. This helps users understand how to use the new capabilities and ensures the documentation stays relevant.

 - **Comments**: Explain *why*, not *what*
 - **Docs**: Update `docs/content/` when adding features or changing config
+- **New API endpoints**: LocalAI advertises its capability surface in several independent places — swagger `@Tags`, `/api/instructions` registry, auth `RouteFeatureRegistry`, React UI `capabilities.js`, docs. Read [.agents/api-endpoints-and-auth.md](.agents/api-endpoints-and-auth.md) and follow its checklist — missing any surface means clients, admins, and the UI won't know the endpoint exists.
 - **Build**: Inspect `Makefile` and `.github/workflows/` — ask the user before running long builds

+# insightface backend (LocalAI)
+
+Face recognition backend backed by ONNX Runtime. Provides face
+verification (1:1), face analysis (age/gender), face detection, face
+embedding, and — via LocalAI's built-in vector store — 1:N
+identification.
+
+## Engines
+
+This backend ships with **two** interchangeable engines selected via
+`LoadModel.Options["engine"]`:
+
+| engine | Implementation | Models | License |
+|---|---|---|---|
+| `insightface` (default) | `insightface.app.FaceAnalysis` | `buffalo_l`, `buffalo_s`, `antelopev2` | **Non-commercial research use only** |
+| `onnx_direct` | OpenCV `FaceDetectorYN` + `FaceRecognizerSF` | OpenCV Zoo YuNet + SFace | Apache 2.0 (commercial-safe) |
+
+Both engines implement the same `FaceEngine` protocol in `engines.py`,
+so the gRPC servicer in `backend.py` doesn't need to know which one is
+active.
+
+## LoadModel options
+
+Common:
+
+| option | default | description |
+|---|---|---|
+| `engine` | `insightface` | one of `insightface`, `onnx_direct` |
+| `det_size` | `640x640` (insightface), `320x320` (onnx_direct) | detector input size |
+| `det_thresh` | `0.5` | detector confidence threshold |
+| `verify_threshold` | `0.35` | default cosine distance cutoff for FaceVerify |
+
+`insightface` engine:
+
+| option | default | description |
+|---|---|---|
+| `model_pack` | `buffalo_l` | which insightface pack to load |
+
+`onnx_direct` engine:
+
+| option | default | description |
+|---|---|---|
+| `detector_onnx` | *(required)* | path to YuNet-compatible ONNX |
+| `recognizer_onnx` | *(required)* | path to SFace-compatible ONNX |
+
+## Adding a new model pack
+
+1. If it's an insightface pack (auto-downloadable or manually extracted
+   into `~/.insightface/models/<name>/`), just add a new gallery entry
+   in `backend/index.yaml` with `options: ["engine:insightface",
+   "model_pack:<name>"]`. No code change.
+2. If it's an Apache-licensed ONNX pair, add a gallery entry with
+   `options: ["engine:onnx_direct", "detector_onnx:...",
+   "recognizer_onnx:..."]`. If the detector or recognizer has a
+   different input-tensor shape than YuNet/SFace, you may need a new
+   engine implementation in `engines.py`; the two-engine seam makes
+   that a self-contained change.
+
+## Running tests locally
+
+```bash
+make -C backend/python/insightface         # install deps + bake models
+make -C backend/python/insightface test    # run test.py
+```
+
+The OpenCV Zoo tests skip gracefully when `/models/opencv/*.onnx` is
+absent (e.g. on dev boxes where `install.sh` wasn't run).

+# speaker-recognition
+
+Speaker (voice) recognition backend for LocalAI. The audio analog to
+`insightface` — produces speaker embeddings and supports 1:1 voice
+verification and voice demographic analysis.
+
+## Engines
+
+- **SpeechBrainEngine** (default): ECAPA-TDNN trained on VoxCeleb.
+  192-d L2-normalised embeddings, cosine distance for verification.
+  Auto-downloads from HuggingFace on first LoadModel.
+- **OnnxDirectEngine**: Any pre-exported ONNX speaker encoder
+  (WeSpeaker ResNet, 3D-Speaker ERes2Net, CAM++, …). Model path comes
+  from the gallery `files:` entry.
+
+Engine selection is gallery-driven: if the model config provides
+`model_path:` / `onnx:` the ONNX engine is used, otherwise the
+SpeechBrain engine.
+
+## Endpoints
+
+- `POST /v1/voice/verify` — 1:1 same-speaker check.
+- `POST /v1/voice/embed` — extract a speaker embedding vector.
+- `POST /v1/voice/analyze` — voice demographics, loaded lazily on
+  the first analyze call:
+  - **Emotion** (default, opt-out): `superb/wav2vec2-base-superb-er`
+    (Apache-2.0), 4-way categorical (neutral / happy / angry / sad).
+  - **Age + gender** (opt-in): no default — wire a checkpoint with a
+    standard `Wav2Vec2ForSequenceClassification` head via
+    `age_gender_model:<repo>` in options. The Audeering
+    age-gender model is *not* usable as a drop-in because its
+    multi-task head isn't loadable via `AutoModelForAudioClassification`.
+
+  Both heads are optional. When nothing loads, the engine returns 501.
+
+## Audio input
+
+Audio is materialised by the HTTP layer to a temp wav before calling
+the gRPC backend. Accepted input forms on the HTTP side: URL, data-URI,
+or raw base64. The backend itself always receives a filesystem path.
