 ## Workspace Restriction

-Filesystem tools (`read_file`, `write_file`, `edit_file`, `list_dir`) resolve paths through `_resolve_path` (`agent/tools/filesystem.py`), which enforces that the resolved path must lie under `allowed_dir` (typically the configured workspace), plus the media upload directory (`get_media_dir()`) and any `extra_allowed_dirs`.
+Filesystem tools (`read_file`, `write_file`, `edit_file`, `list_dir`, `apply_patch`) resolve paths through the workspace path resolver (`agent/tools/filesystem.py` / `agent/tools/path_utils.py`), which enforces that the resolved path must lie under the active workspace when workspace restriction is enabled. The media upload directory is always an internal extra read root while restricted.

-Shell execution (`ExecTool`, `agent/tools/shell.py`) also respects `restrict_to_workspace`: if enabled and `working_dir` is outside the workspace, the command is rejected before execution.
+Additional filesystem roots must be capability-specific. `extra_allowed_dirs` is a legacy read-only alias. Use `extra_read_allowed_dirs` for read-only roots, `extra_write_allowed_dirs` only when a write-capable tool is intentionally allowed to modify an extra directory, and exact file allowlists when a tool may modify only specific files.

-**Rule**: Any new path-handling logic must go through `_resolve_path` or perform an equivalent `allowed_dir` check.
+Shell execution (`ExecTool`, `agent/tools/shell.py`) also respects `restrict_to_workspace` as an application-level guard: if enabled and `working_dir` is outside the workspace, the command is rejected before execution, and command text is checked for obvious workspace escapes. This is not process-level isolation; use an exec sandbox backend for that.

+history, memory, streaming events, and runtime helpers.

-Before debugging SDK code, prove the same config works from the CLI:
+If you have used the OpenAI SDK before, the most important difference is this:
+
+- OpenAI SDK calls a model.

+      -> memory

+## Before You Start

+environments, install the package with:

+Use `async with` when possible so tool connections and background cleanup are
+closed before the event loop exits. If you manage the instance manually, call
+`await bot.aclose()` in a `finally` block.
+
+The SDK is async-first because agent runs may stream tokens, execute tools, and
+wait on external services. In a normal Python script, wrap your async function
+with `asyncio.run(...)` as shown above. In a notebook or another async app, call
+`await bot.run(...)` directly from your existing event loop.
+
+### Inspect What Happened
+
+`bot.run(...)` returns a `RunResult`, not just a string:
+
+```python
+result = await bot.run("Review this repository")
+
+print(result.content)     # final answer
+print(result.tools_used)  # tools the agent used
+print(result.usage)       # token usage when available
+print(result.stop_reason) # why the run stopped
+```
+
+### Continue A Conversation
+
+Use a `session_key` when you want history to carry across turns. Different
+session keys are isolated from each other:
+
+```python
+await bot.run("My name is Alice.", session_key="user:alice")
+result = await bot.run("What is my name?", session_key="user:alice")
+
+print(result.content)
+```
+
+This is the SDK equivalent of giving each user, task, eval case, or workflow
+its own conversation thread.
+
+### Stream A Long Answer
+
+For live output, use `bot.stream(...)`:
+
+```python
+from nanobot import STREAM_EVENT_TEXT_DELTA
+
+async for event in bot.stream("Write a migration plan"):
+    if event.type == STREAM_EVENT_TEXT_DELTA:
+        print(event.delta, end="", flush=True)

+
+Streaming returns structured events, so you can also observe tool calls,

+
+You should see the configured model, workspace path, streamed assistant text,
+and final run metadata. The exact answer depends on your config and workspace,
+but a file-listing prompt may look like this:
+
+```text
+model: openai/gpt-4.1-mini
+workspace: /Users/alice/.nanobot/workspace
+
+[tool] list_dir
+Here are the top-level files I found...
+
+stop_reason: completed
+tools_used: ['list_dir']
+usage: {'prompt_tokens': ..., 'completion_tokens': ..., 'total_tokens': ...}
+```
+
+This script shows the usual production shape: create one `Nanobot`, choose a
+stable `session_key`, stream events, keep the final `RunResult`, and let
+`async with` close runtime resources.
+
+## Core Concepts
+
+| Concept | Meaning |
+|---------|---------|
+| `Nanobot` | The SDK object that owns one configured agent runtime. |
+| Run | One call to `bot.run(...)`, `bot.run_streamed(...)`, or `bot.stream(...)`. |
+| `session_key` | The conversation history key. Reuse it to continue a thread; change it to isolate a thread. |
+| Workspace | The local directory where file tools and shell tools operate. |
+| Tools | Capabilities the agent may call, such as file access, shell, web, or custom tools from your config. |
+| Memory | Long-term memory files managed by nanobot. |
+| Stream event | A typed event such as `text.delta`, `tool.started`, or `run.completed`. |
+| Model override | A temporary model or model preset used for one SDK instance or one run. |
+
+For most users, the mental model is:
+
+1. Create a `Nanobot` from config.
+2. Pick a `session_key`.
+3. Call `run` or `stream`.
+4. Read `RunResult` or stream events.
+5. Use session/memory/runtime helpers only when you need more control.
+
+## SDK Or OpenAI-Compatible API?
+
+nanobot has two programming surfaces:
+
+| Use | Choose | Why |
+|-----|--------|-----|
+| Python code running in the same process as nanobot | Python SDK | Direct access to `RunResult`, sessions, memory, runtime helpers, hooks, and stream events. |
+| Existing OpenAI-compatible clients, another language, or a separate process | [OpenAI-Compatible API](openai-api.md) | HTTP `/v1/chat/completions` compatibility with familiar client libraries. |
+
+The Python SDK is best when you are writing evals, notebooks, benchmark
+runners, product backends, local scripts, or integrations that should control
+nanobot directly.
+
+The OpenAI-compatible API is best when you already have an HTTP client, want
+process isolation, or need to call nanobot from a non-Python service.

 ## Common Patterns

 ### Use a specific config or workspace

+Set the workspace when your agent should work inside a specific project:
+
 ```python
 from nanobot import Nanobot

-bot = Nanobot.from_config(
-    config_path="~/.nanobot/config.json",
-    workspace="/my/project",
-)
+async with Nanobot.from_config(workspace="/my/project") as bot:
+    result = await bot.run("Explain the project structure")
 ```

+Use a custom config when you run multiple nanobot instances or test an isolated
+setup:
+
+```python
+async with Nanobot.from_config(
+    config_path="./bot-a/config.json",
+    workspace="./bot-a/workspace",
+) as bot:
+    result = await bot.run("Hello from bot A")
+```
+
+The config controls what nanobot may use. The workspace is where nanobot keeps
+state for that instance. See [multiple-instances.md](multiple-instances.md) for
+multi-instance CLI and gateway examples.
+
+### Choose a default or per-run model
+
+Set the SDK instance default model when you create the bot:
+
+```python
+bot = Nanobot.from_config(model="openai/gpt-4.1")
+```
+
+Override the model for one run without changing the instance default:
+
+```python
+result = await bot.run("Summarize this file", model="openai/gpt-4.1-mini")
+```
+
+Model presets from `config.json` work the same way:
+
+```python
+bot = Nanobot.from_config(model_preset="fast")
+
+result = await bot.run("Think deeply about this bug", model_preset="reasoning")
+```
+
+`model` and `model_preset` are mutually exclusive.
+
+For first setup, prefer named presets in `config.json`. Mixing an API key from
+one provider with a model ID from another is the most common first-run failure.
+For the exact difference between `provider`, `model`, `apiKey`, and `apiBase`,
+see [Providers: Provider, Model, API Key, and Base URL](providers.md#provider-model-api-key-and-base-url).
+If a run fails before the SDK does anything interesting, confirm the same
+provider and model work with `nanobot agent -m "Hello!"` first.
+
 ### Isolate conversations with `session_key`

 Different session keys keep independent conversation history:
@@ -51,9 +306,131 @@ await bot.run("hi", session_key="user-alice")
 await bot.run("hi", session_key="task-42")
 ```

+Use stable keys in product code:
+
+```python
+session_key = f"user:{user_id}"
+result = await bot.run(user_message, session_key=session_key)
+```
+
+Avoid using the default `"sdk:default"` for multiple users or unrelated
+workflows. It is convenient for local experiments, but stable product code
+should choose explicit keys such as `user:<id>`, `project:<id>`, or
+`eval:<case-id>`.
+
+### Handle failures
+
+For a normal non-streamed run, catch exceptions around `bot.run(...)` and inspect
+`RunResult.error` when the runtime returns a structured failure:
+
+```python
+try:
+    result = await bot.run("Review this repo", session_key="project:demo")
+except Exception as exc:
+    print(f"SDK call failed before a result was returned: {exc}")
+else:
+    if result.error:
+        print(f"Agent run failed: {result.error}")
+    else:
+        print(result.content)
+```
+
+For streamed runs, either consume the stream to completion or close it:
+
+```python
+run = await bot.run_streamed("Write a long answer", session_key="task:123")
+try:
+    async for event in run.stream_events():
+        ...
+finally:
+    if not run.done:
+        await run.aclose()
+```
+
+Use `await run.cancel()` when the user presses a stop button or leaves the page
+before the stream finishes.
+
+### Stream long-running output
+
+Use `bot.stream()` when you want Cursor/OpenAI-style live events instead of
+waiting for the final `RunResult`:
+
+```python
+from nanobot import (
+    STREAM_EVENT_RUN_COMPLETED,
+    STREAM_EVENT_TEXT_DELTA,
+    STREAM_EVENT_TOOL_STARTED,
+)
+
+async for event in bot.stream("Review this repository"):
+    if event.type == STREAM_EVENT_TEXT_DELTA:
+        print(event.delta, end="", flush=True)
+    elif event.type == STREAM_EVENT_TOOL_STARTED:
+        print(f"\nusing {event.name}")
+    elif event.type == STREAM_EVENT_RUN_COMPLETED:
+        print("\nfinal:", event.result.content)
+```
+
+Use `run_streamed()` when you also want a handle you can wait on:
+
+```python
+from nanobot import STREAM_EVENT_TEXT_DELTA
+
+run = await bot.run_streamed("Write a detailed migration plan")
+
+async for event in run.stream_events():
+    if event.type == STREAM_EVENT_TEXT_DELTA:
+        print(event.delta, end="", flush=True)
+
+result = await run.wait()
+```
+
+Always either consume the stream, call `await run.wait()` / `await run.text()`,
+or close it with `await run.cancel()` / `await run.aclose()`. Exiting
+`stream_events()` or `bot.stream()` early cancels the underlying run so a
+half-consumed stream cannot leave a background task stuck behind backpressure.
+
+### Import an existing transcript
+
+This is useful for evals, benchmark runners, migrations, and tests.
+
+Use `bot.sessions.ingest()` when you already have a transcript and want it to
+become nanobot session history. Ingesting a transcript does not call the model,
+execute tools, update memory, or compact automatically.
+
+```python
+await bot.sessions.ingest(
+    "eval:case-1",
+    [
+        {
+            "role": "user",
+            "content": "I graduated with a degree in Business Administration.",
+            "timestamp": "2023/05/30 (Tue) 17:27",
+            "source_session_id": "answer_280352e9",
+        },
+        {
+            "role": "assistant",
+            "content": "Congratulations on your degree.",
+            "timestamp": "2023/05/30 (Tue) 17:27",
+        },
+    ],
+    source="longmemeval",
+)
+
+await bot.runtime.compact_session("eval:case-1")
+

+workspace metadata, and linked automations. Use a new session when you want a
+separate context; use fork when you want to continue from an existing point
+without changing the original thread.
+
+The message timeline shows both user-visible replies and agent activity. Long
+tool or reasoning sections can be expanded when you need the details.
+
+## Workspace and Access
+
+Use the workspace picker before starting project-specific work. This gives the
+agent the right project context for file paths, shell commands, and session
+metadata.
+
+The access control in the composer controls the local capability level for the
+chat. It does not bypass your gateway, provider, shell sandbox, or operating
+system configuration; it only selects among the capabilities that are already
+available to this WebUI session.
+
+## Composer
+
+The composer supports plain messages, image attachments, voice input when
+transcription is configured, slash commands, and `@` mentions for installed Apps
+or MCP presets. The model badge shows the current model or preset and links back
+to model settings when setup is incomplete.
+
+For image generation, configure an image provider first and then use the WebUI
+image mode from the composer. See [`image-generation.md`](./image-generation.md)
+for provider setup and output behavior.
+
+## Apps
+
+Open Apps from the sidebar or settings navigation to manage integrations that
+nanobot can call from a chat. CLI Apps install local adapters that nanobot runs
+on your machine; they do not modify the native apps themselves. MCP presets add
+predefined MCP server configurations.
+
+Some MCP presets connect to hosted keyless endpoints. For example, the Firecrawl
+preset uses Firecrawl's hosted MCP endpoint for search, scrape, crawl, and
+extraction tools without requiring an API key. This does not replace nanobot's
+built-in web search provider; mention the Firecrawl MCP preset with `@` when a
+turn needs Firecrawl's richer web data tools.
+
+After an App or MCP preset is available, mention it from the composer with `@`
+to attach that capability to the next message.
+
+## Skills
+
+The Skills view shows the skill instructions available to the agent, including
+built-in skills and workspace-provided skills. Check this view when you want to
+know whether nanobot already has a focused workflow for a task before you ask it
+to perform that task.
+
+## Automations
+
+Automations are scheduled agent turns. They should be created from the chat,
+channel, or session where they are supposed to run so nanobot keeps the correct
+target context.
+
+Use the Automations view to:
+
+- Filter by all, active, paused, needs-attention, or system jobs.
+- Search by task name, message, linked chat, schedule, or status.
+- Sort by next run, last run, updated time, or name.
+- Run now, pause or resume, edit, or delete user-created automations.
+- Inspect protected system automations without changing them.
+
+Search accepts plain text and field filters such as `name:backup`,
+`chat:WeChat`, `schedule:09:30`, `cron:"0 23 * * *"`, and `status:paused`.
+
+An automation without a linked chat cannot be enabled or run from the WebUI,
+because nanobot would not know where to deliver the scheduled turn. Recreate it
+from the target chat or channel so the automation has complete context.
+
+## Settings
+
+Settings is the control surface for the browser session and gateway-backed
+runtime configuration. Use it to review or adjust model presets, provider
+visibility, image generation, voice transcription, web tools, Apps, Automations,
+Skills, runtime identity, and advanced safety controls.
+
+Some settings take effect immediately. Runtime settings that affect the gateway
+or agent process may require a restart; the WebUI shows that requirement next to
+the relevant control.
+
+## LAN Access
+
+To open the WebUI from another device on the same network, bind the WebSocket
+channel to all interfaces and set a token or token issue secret:
+
+```json
+{
+  "channels": {
+    "websocket": {
+      "enabled": true,
+      "host": "0.0.0.0",
+      "port": 8765,
+      "tokenIssueSecret": "your-secret-here"
+    }
+  }
+}
+```
+
+The gateway refuses to start with `host` set to `"0.0.0.0"` unless `token` or
+`tokenIssueSecret` is configured. After the gateway starts, open
+`http://<your-ip>:8765` from the other device and enter the secret in the login
+form.
+
+## Troubleshooting
+
+If the page does not open, check these in order:
+
+1. `nanobot agent -m "Hello!"` works in the same Python environment.
+2. The WebSocket channel is enabled in `~/.nanobot/config.json`.
+3. `nanobot gateway` is still running.
+4. You are opening port `8765`, not the gateway health port.
+5. LAN access uses `host: "0.0.0.0"` and a token or token issue secret.
+

+[`troubleshooting.md#webui-problems`](./troubleshooting.md#webui-problems).
+For frontend development, see [`../webui/README.md`](../webui/README.md).
