 - **Config** (`nanobot/config/schema.py`, `loader.py`): Pydantic-based configuration loaded from `~/.nanobot/config.json`. Supports camelCase aliases for JSON compatibility.

 - **WebUI** (`webui/`): Vite-based React SPA that talks to the gateway over a WebSocket multiplex protocol. The dev server proxies `/api`, `/webui`, `/auth`, and WebSocket traffic to the gateway.
 - **API Server** (`nanobot/api/server.py`): OpenAI-compatible HTTP API (`/v1/chat/completions`, `/v1/models`) for programmatic access.
 - **Command Router** (`nanobot/command/`): Slash command routing and built-in command handlers.

+send a message into the current chat/session later. A name is required; plain
+`/trigger` only shows the usage hint.
+
+Create the trigger from the chat where future messages should arrive:
+
+```text
+/trigger PR review
+```
+
+nanobot replies with a trigger ID and a command shaped like:
+
+```bash
+nanobot trigger trg_8K4P2Q9X "Review PR #4502"
+```
+
+Replace `"Review PR #4502"` with the message you want nanobot to receive. The
+trigger is bound to the session where it was created, so the message goes back
+to that same chat. Keep `nanobot gateway` running so trigger messages can be
+delivered. The trigger message starts an automation turn recorded in that
+session with the message you passed to the CLI; it is not treated as a normal
+user message. If that session is already running a turn, the trigger waits
+until the session is idle instead of being injected into the active turn.
+
+Trigger deliveries are stored in the workspace until their linked agent turn
+finishes successfully. If the gateway exits after claiming a delivery but before
+the turn completes, the next gateway start requeues that delivery. This is an
+at-least-once local queue: a delivery may run more than once if the process
+exits at the wrong time, so external scripts should make repeated trigger
+messages safe. If the delivery reaches the agent and the agent turn fails, the
+delivery is marked failed in Automations instead of retrying forever.
+
+For longer or generated content, omit the message argument and pipe stdin:
+
+```bash
+printf '%s\n' "Review the latest failed CI job" | nanobot trigger trg_8K4P2Q9X
+```
+
+If an external webhook should wake nanobot up, run your own small webhook
+service and have it call the trigger command after it builds the final message:
+
+```bash
+nanobot trigger <trigger-id> "<message>"
+```
+
+If you run multiple nanobot instances, pass the same config or workspace
+selector used by the gateway:
+
+```bash
+nanobot trigger --config ./bot-a/config.json trg_8K4P2Q9X "Nightly report"
+nanobot trigger --workspace ./bot-a/workspace trg_8K4P2Q9X "Nightly report"
+```
+
+Manage triggers from the WebUI Automations view. You can search, pause/resume,
+rename, delete, and copy the trigger command there. A session may have multiple
+triggers, just like it may have multiple scheduled automations.
+
 ## Periodic Tasks
 
-Periodic tasks 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 results to your most recently active chat channel. If there are no active tasks, the heartbeat is skipped silently.

 **Setup:** edit `~/.nanobot/workspace/HEARTBEAT.md` (created automatically by `nanobot onboard`):
 
 ```markdown
 ## Active Tasks
 
-- Check weather forecast and send a summary
-- Scan inbox for urgent emails
+- Check weather forecast and notify me only if storms are expected
+- Scan inbox for urgent emails and notify me if any are found
 ```

+

+a chat/session with `/trigger <name>`.
+
+```bash
+nanobot trigger trg_8K4P2Q9X "Review PR #4502"
+```
+
+Keep `nanobot gateway` running so the message can be delivered to the linked
+chat/session. The message is recorded as an automation turn in that session,
+not as a normal chat message typed by the user.
+
+The command writes to a workspace-local durable queue. If `nanobot gateway` is
+not running yet, the message waits in that workspace. If the target session is
+already running a turn, the trigger waits for that session to become idle. If the
+gateway exits after claiming a delivery but before the linked turn completes,
+the next gateway start requeues that delivery. The queue is at-least-once, not
+exactly-once, so the same message can be delivered again after an interrupted
+process. If the agent receives the delivery and the turn fails, the delivery is
+marked failed instead of retried indefinitely. Each delivery also writes an
+audit record under `<workspace>/triggers/runs`. Run one gateway consumer per
+workspace; this local queue is not a distributed multi-consumer queue.

-## Webhooks
-
-Webhooks let external systems start a nanobot turn by sending an authenticated HTTP `POST` to the gateway health port. They are event sources, not chat channels: the HTTP caller gets an immediate JSON acceptance response, and the agent's actual reply is delivered to the configured chat target.
-
-`nanobot gateway` serves webhook routes on `gateway.host:gateway.port`, the same small HTTP listener that serves `/health`. If the gateway is behind a tunnel or reverse proxy, terminate TLS and public host policy there, then forward only the route paths you need.
-
-### Generic route

-      }

-```
-
-The default route path is `/webhooks/<route-name>`, so the example above listens on `/webhooks/deploy`. Set `path` only when the external platform requires a different URL.

-```text
-Authorization: Bearer <secret>
-X-Nanobot-Auth: <secret>
-X-Nanobot-Signature-256: sha256=<hmac_sha256(raw_body, secret)>
-```
-
-Use the HMAC header when the sender supports request signing. Bearer-style headers are simpler for systems that only support static secret headers. `auth: "none"` is available for trusted local-only integrations, but do not expose unauthenticated routes to the public internet.

+Local-only `127.0.0.1` usage does not require an API key. If you bind the API
+server to all interfaces with `api.host: "0.0.0.0"` or `"::"`, nanobot requires
+`api.apiKey`; otherwise startup fails to avoid exposing an unauthenticated agent
+endpoint on the network.

+When `api.apiKey` is set, send it as a Bearer token on API routes. The health
+endpoint remains unauthenticated so local probes and load balancers can still
+check process health.

 You usually omit `apiBase` for hosted built-in providers such as OpenRouter, Anthropic direct, OpenAI direct, Groq, or Bedrock because nanobot knows their default endpoints. Set `apiBase` for `custom`, local OpenAI-compatible servers, provider proxies, regional endpoints, or subscription endpoints. Include the API version path when the endpoint requires it, for example `https://api.example.com/v1` or `http://localhost:11434/v1`.
 
+Use `proxy` when one provider must send HTTP traffic through a proxy without changing process-wide `HTTP_PROXY` / `HTTPS_PROXY`. This is supported for providers that use nanobot's OpenAI-compatible client, including `openai`, `custom`, named custom providers, OpenRouter-style gateways, local OpenAI-compatible servers, and similar registry entries. It is also supported for `openai_codex`, including Codex OAuth token exchange/refresh and Codex Responses API requests. Native provider backends such as `anthropic`, `bedrock`, `azure_openai`, and `github_copilot` reject `proxy`; use their endpoint-specific configuration instead.

 Custom provider keys are treated as direct OpenAI-compatible providers. `apiBase` is required because nanobot cannot know the endpoint URL. `apiKey` is optional for local servers or private proxies that do not require one. Choose a name that does not conflict with a built-in provider name or alias, such as `openai`, `openai-codex`, `github-copilot`, or `lm-studio`. Do not set `apiType` on custom provider keys; `apiType` is only for `providers.openai`.
 
+If your custom endpoint documents a nonstandard thinking toggle, set `providers.<name>.thinkingStyle` to `thinking_type`, `enable_thinking`, or `reasoning_split`; nanobot then maps `reasoningEffort` onto that provider-specific request body. Leave it unset for ordinary OpenAI-compatible endpoints.

 This named custom provider path is not for Anthropic-compatible endpoints. For Anthropic-compatible proxies, use `providers.anthropic.apiBase` and set the preset provider to `anthropic`.

 ## 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.
+Automations are agent turns that run later in a linked chat/session. 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.
+
+There are two user-facing automation types:
+
+- Scheduled automations, created by the agent's cron tool, run at a time,
+  interval, or cron expression.
+- Local triggers, created with `/trigger <name>`, run when you call a local
+  command such as `nanobot trigger trg_8K4P2Q9X "Review PR #4502"`.
+
+If a GitHub webhook, CI system, or another service should wake nanobot up, keep
+that webhook/service outside nanobot and have it call the trigger command with
+the final message.
+
+Trigger deliveries use the same workspace as the gateway. They survive gateway
+restarts and are requeued if the process exits before the linked turn completes.
+If the linked session is already running a turn, the local trigger waits until
+that session is idle instead of being injected into the active turn. This is an
+at-least-once local queue, so repeated delivery is possible after an interrupted
+process. A delivered trigger is recorded as an automation turn in the linked
+session; if the agent receives it but the turn fails, Automations marks the run
+failed instead of retrying indefinitely.
+
+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.
+- Search by task name, message, trigger command, 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.
+- Run scheduled automations now.
+- Pause or resume, rename, or delete user-created automations.
+- Copy the CLI command for local triggers.
 - 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`.
+`chat:WeChat`, `schedule:09:30`, `cron:"0 23 * * *"`, `trigger`, 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.
 
+Local triggers do not have a WebUI "Run now" action because each run needs a
+message. Use the copied `nanobot trigger ...` command and replace `"message"`
+with the content that should be delivered.
