 ## Workspace Restriction
 
-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.
+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`.
 
-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.
+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.
 
-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.

-Periodic background checks are driven by `HEARTBEAT.md` in your workspace (`~/.nanobot/workspace/HEARTBEAT.md`). When `nanobot gateway` starts, it registers a protected heartbeat cron job by default. Every 30 minutes, that job checks the file; if it finds tasks under `## Active Tasks`, the agent executes them and delivers only results that pass the notification gate to your most recently active chat channel.

+Use nanobot as a library — no CLI, no gateway, just Python.
 
-If you have used the OpenAI SDK before, the most important difference is this:
-
-- OpenAI SDK calls a model.
-- nanobot SDK runs an agent around a model.
-
-That means one SDK call can read files, call tools, keep session history, use

-      -> memory
-```
-
-## Before You Start
-
-Install and configure nanobot first. If you have not done that yet, follow the
-[Quick Start](quick-start.md) and complete the setup wizard. For SDK-only Python
-environments, install the package with:
-
-```bash
-python -m pip install nanobot-ai

-workspace, see [Concepts: Config vs Workspace](concepts.md#config-vs-workspace).
-
-Before writing SDK code, run the same first-run checks from the main
-[Install and Quick Start](quick-start.md):
-
-```bash
-nanobot status
-```
-
-`nanobot status` should show the config path, workspace path, active model or
-preset, and provider summary. Then send one real message:
+Before debugging SDK code, prove the same config works from the CLI:

-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,
-reasoning chunks, completion, and failures.

-## 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.
+Use `async with` when possible so MCP connections and background cleanup work are closed before the event loop exits. If you manage the instance manually, call `await bot.aclose()` in a `finally` block.
 
 ## 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
 
-async with Nanobot.from_config(workspace="/my/project") as bot:
-    result = await bot.run("Explain the project structure")
+bot = Nanobot.from_config(
+    config_path="~/.nanobot/config.json",
+    workspace="/my/project",
+)
 ```
 
-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:
@@ -306,131 +51,9 @@ await bot.run("hi", session_key="user-alice")

-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",
-    [
-        {

-### `await bot.run_streamed(...)`
-
-Start a streamed agent turn and return a `RunStream`. It accepts the same
-parameters as `bot.run(...)`.
-
-```python
-run = await bot.run_streamed("Generate a long answer")
-
-async for event in run.stream_events():

-### `RunStream`
-
-| Method | Description |
-|--------|-------------|
-| `stream_events()` | Single-consumer async iterator of `StreamEvent` objects. |
-| `await wait()` | Wait for the run to finish and return `RunResult`. |
-| `await text()` | Wait for the run to finish and return `RunResult.content`. |
-| `await cancel()` | Cancel the run and release stream resources. |
-| `await aclose()` | Close the stream; equivalent cleanup primitive for `async with` / manual lifecycle code. |
-
-Normal SDK runs with different session keys may overlap. Runs that use per-run
-`model` or `model_preset` overrides are exclusive while the override is active,
-because the current `AgentLoop` provider/model state is mutable.
-
-### `StreamEvent`
-
-| Field | Type | Description |
-|-------|------|-------------|
-| `type` | `StreamEventType` | Event type, such as `text.delta` or `run.completed`. |
-| `delta` | `str` | Incremental text or reasoning chunk. |
-| `content` | `str` | Completed text segment or final content. |
-| `result` | `RunResult \| None` | Present on `run.completed`. |
-| `name` | `str \| None` | Tool name for tool events. |
-| `tool_call_id` | `str \| None` | Provider tool call id when available. |
-| `arguments` | `dict \| None` | Tool arguments when available. |
-| `iteration` | `int \| None` | Agent loop iteration when available. |
-| `resuming` | `bool \| None` | Whether a text segment ended before more tool work. |
-| `usage` | `dict[str, int]` | Token usage on completion events. |
-| `error` | `str \| None` | Error text on failed events. |
-| `metadata` | `dict` | Additional event metadata. |
-
-Use the exported constants instead of hard-coded strings when possible:
-
-| Constant | Value |
-|----------|-------|
-| `STREAM_EVENT_RUN_STARTED` | `run.started` |
-| `STREAM_EVENT_TEXT_DELTA` | `text.delta` |
-| `STREAM_EVENT_TEXT_COMPLETED` | `text.completed` |

-# WebUI
-
-The WebUI is nanobot's browser workbench. Use it after a basic CLI reply already
-works, when you want a persistent chat workspace, visible agent activity,
-workspace controls, Apps, Skills, settings, and Automations in one place.
-
-The published `nanobot-ai` wheel already includes the WebUI bundle. You only need
-the `webui/` source directory when you are changing the frontend itself.
-
-## Open the WebUI
-
-First confirm your provider and model can answer:
-
-```bash
-nanobot agent -m "Hello!"
-```
-
-Then merge the WebSocket channel into your existing `~/.nanobot/config.json`.
-Set `tokenIssueSecret` to the password you will enter in the WebUI login form:
-
-```json
-{
-  "channels": {
-    "websocket": {
-      "enabled": true,
-      "tokenIssueSecret": "your-webui-password",
-      "websocketRequiresToken": true
-    }
-  }
-}
-```
-
-If you are new to JSON snippets, see
-[`start-without-technical-background.md#how-to-merge-json-snippets`](./start-without-technical-background.md#how-to-merge-json-snippets).
-
-Start the gateway:
-
-```bash
-nanobot gateway
-```
-
-Leave the gateway running and open
-[`http://127.0.0.1:8765`](http://127.0.0.1:8765). The WebUI is served by the
-WebSocket channel on port `8765` by default. The gateway health endpoint,
-`18790` by default, is not the browser UI.
-Enter `tokenIssueSecret` when the WebUI asks for a password.
-
-## What It Is For
-
-| Area | Use it for |
-|---|---|
-| Chat | Start, switch, search, fork, and delete browser sessions |
-| Agent activity | See thinking, tool calls, file activity, command output, and generated artifacts in context |
-| Workspace | Pick the project workspace before asking for file or shell work |
-| Access | Choose the access mode for local capabilities allowed by your gateway configuration |
-| Composer | Send text, images, voice input, slash commands, and `@` mentions for Apps or MCP presets |
-| Apps | Install, test, update, and use local CLI App adapters and MCP presets |
-| Skills | Inspect available built-in and workspace skills before relying on them |
-| Automations | Review, search, run, pause, edit, and delete scheduled agent turns |
-| Settings | Adjust models, providers, image generation, voice, web tools, runtime, and safety options |
-
-## Chat Workspace
-
-The sidebar is the session switcher. A session keeps its own history, title,
-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. When an automation runs, it normally delivers the result back to
-that linked chat.
-
-For recurring background checks that should stay quiet unless there is something
-useful to report, use the protected heartbeat job by editing `HEARTBEAT.md`
-instead of creating a chat automation.
-
-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.
