 Dead code behind the wrong `#[cfg]` gate will only show up when building with a single feature.

+**Zero clippy warnings policy:** Fix ALL clippy warnings before committing, including pre-existing ones in files you didn't change. Never leave warnings behind — treat `cargo clippy` output as a zero-tolerance gate.

 **Mechanical verification before committing:** Run these checks on changed files before committing:
+- `cargo clippy --all --benches --tests --examples --all-features` -- zero warnings

 - `grep -rn 'super::' <files>` -- use `crate::` imports

 **NEAR AI** -- Uses the Chat Completions API with dual auth support. Session token auth (default): authenticates with session tokens (`sess_xxx`) obtained via browser OAuth (GitHub/Google), base URL defaults to `https://private.near.ai`. API key auth: set `NEARAI_API_KEY` (from `cloud.near.ai`), base URL defaults to `https://cloud-api.near.ai`. Both modes use the same Chat Completions endpoint. Tool messages are flattened to plain text for compatibility. Set `NEARAI_SESSION_TOKEN` env var for hosting providers that inject tokens via environment.

+**NEAR AI Cloud** -- Uses the OpenAI-compatible Chat Completions API (`https://cloud-api.near.ai/v1/chat/completions`). Authenticates with API keys from `cloud.near.ai`. Auto-selected when `NEARAI_API_KEY` is set (or explicitly via `NEARAI_API_MODE=chat_completions`). Tool messages are flattened to plain text for compatibility. Configure with `NEARAI_API_KEY` and `NEARAI_BASE_URL` (default: `https://cloud-api.near.ai`).
+
+**OpenAI-compatible** -- Any endpoint that speaks the OpenAI API (vLLM, LiteLLM, OpenRouter, etc.). Configure with `LLM_BASE_URL`, `LLM_API_KEY` (optional), `LLM_MODEL`. Set `LLM_EXTRA_HEADERS` to inject custom HTTP headers into every request (format: `Key:Value,Key2:Value2`), useful for OpenRouter attribution headers like `HTTP-Referer` and `X-Title`.
+
 **Tinfoil** -- Private inference via `https://inference.tinfoil.sh/v1`. Runs models inside hardware-attested TEEs so neither Tinfoil nor the cloud provider can see prompts or responses. Uses the OpenAI-compatible Chat Completions API. Configure with `TINFOIL_API_KEY` and `TINFOIL_MODEL` (default: `kimi-k2-5`).

+# LLM Provider Configuration
+
+IronClaw defaults to NEAR AI for model access, but supports any OpenAI-compatible
+endpoint as well as Anthropic and Ollama directly. This guide covers the most common
+configurations.
+
+## Provider Overview
+
+| Provider | Backend value | Requires API key | Notes |
+|---|---|---|---|
+| NEAR AI | `nearai` | OAuth (browser) | Default; multi-model |
+| Anthropic | `anthropic` | `ANTHROPIC_API_KEY` | Claude models |
+| OpenAI | `openai` | `OPENAI_API_KEY` | GPT models |
+| Ollama | `ollama` | No | Local inference |
+| OpenRouter | `openai_compatible` | `LLM_API_KEY` | 300+ models |
+| Together AI | `openai_compatible` | `LLM_API_KEY` | Fast inference |
+| Fireworks AI | `openai_compatible` | `LLM_API_KEY` | Fast inference |
+| vLLM / LiteLLM | `openai_compatible` | Optional | Self-hosted |
+| LM Studio | `openai_compatible` | No | Local GUI |
+
+---
+
+## NEAR AI (default)
+
+No additional configuration required. On first run, `ironclaw onboard` opens a browser
+for OAuth authentication. Credentials are saved to `~/.ironclaw/session.json`.
+
+```env
+NEARAI_MODEL=claude-3-5-sonnet-20241022
+NEARAI_BASE_URL=https://private.near.ai
+```
+
+---
+
+## Anthropic (Claude)
+
+```env
+LLM_BACKEND=anthropic
+ANTHROPIC_API_KEY=sk-ant-...
+```
+
+Popular models: `claude-sonnet-4-20250514`, `claude-3-5-sonnet-20241022`, `claude-3-5-haiku-20241022`
+
+---
+
+## OpenAI (GPT)
+
+```env
+LLM_BACKEND=openai
+OPENAI_API_KEY=sk-...
+```
+
+Popular models: `gpt-4o`, `gpt-4o-mini`, `o3-mini`
+
+---
+
+## Ollama (local)
+
+Install Ollama from [ollama.com](https://ollama.com), pull a model, then:
+
+```env
+LLM_BACKEND=ollama
+OLLAMA_MODEL=llama3.2
+# OLLAMA_BASE_URL=http://localhost:11434   # default
+```
+
+Pull a model first: `ollama pull llama3.2`
+
+---
+
+## OpenAI-Compatible Endpoints
+
+All providers below use `LLM_BACKEND=openai_compatible`. Set `LLM_BASE_URL` to the
+provider's OpenAI-compatible endpoint and `LLM_API_KEY` to your API key.
+
+### OpenRouter
+
+[OpenRouter](https://openrouter.ai) routes to 300+ models from a single API key.
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=https://openrouter.ai/api/v1
+LLM_API_KEY=sk-or-...
+LLM_MODEL=anthropic/claude-sonnet-4
+```
+
+Popular OpenRouter model IDs:
+
+| Model | ID |
+|---|---|
+| Claude Sonnet 4 | `anthropic/claude-sonnet-4` |
+| GPT-4o | `openai/gpt-4o` |
+| Llama 4 Maverick | `meta-llama/llama-4-maverick` |
+| Gemini 2.0 Flash | `google/gemini-2.0-flash-001` |
+| Mistral Small | `mistralai/mistral-small-3.1-24b-instruct` |
+
+Browse all models at [openrouter.ai/models](https://openrouter.ai/models).
+
+### Together AI
+
+[Together AI](https://www.together.ai) provides fast inference for open-source models.
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=https://api.together.xyz/v1
+LLM_API_KEY=...
+LLM_MODEL=meta-llama/Llama-3.3-70B-Instruct-Turbo
+```
+
+Popular Together AI model IDs:
+
+| Model | ID |
+|---|---|
+| Llama 3.3 70B | `meta-llama/Llama-3.3-70B-Instruct-Turbo` |
+| DeepSeek R1 | `deepseek-ai/DeepSeek-R1` |
+| Qwen 2.5 72B | `Qwen/Qwen2.5-72B-Instruct-Turbo` |
+
+### Fireworks AI
+
+[Fireworks AI](https://fireworks.ai) offers fast inference with compound AI system support.
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=https://api.fireworks.ai/inference/v1
+LLM_API_KEY=fw_...
+LLM_MODEL=accounts/fireworks/models/llama4-maverick-instruct-basic
+```
+
+### vLLM / LiteLLM (self-hosted)
+
+For self-hosted inference servers:
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=http://localhost:8000/v1
+LLM_API_KEY=token-abc123        # set to any string if auth is not configured
+LLM_MODEL=meta-llama/Llama-3.1-8B-Instruct
+```
+
+LiteLLM proxy (forwards to any backend, including Bedrock, Vertex, Azure):
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=http://localhost:4000/v1
+LLM_API_KEY=sk-...
+LLM_MODEL=gpt-4o                 # as configured in litellm config.yaml
+```
+
+### LM Studio (local GUI)
+
+Start LM Studio's local server, then:
+
+```env
+LLM_BACKEND=openai_compatible
+LLM_BASE_URL=http://localhost:1234/v1
+LLM_MODEL=llama-3.2-3b-instruct-q4_K_M
+# LLM_API_KEY is not required for LM Studio
+```
+
+---
+
+## Using the Setup Wizard
+
+Instead of editing `.env` manually, run the onboarding wizard:
+
+```bash
+ironclaw onboard
+```
+
+Select **"OpenAI-compatible"** for OpenRouter, Together AI, Fireworks, vLLM, LiteLLM,
+or LM Studio. You will be prompted for the base URL and (optionally) an API key.
+The model name is configured in the following step.
