+description: Airtable REST API via curl. Records CRUD, filters, upserts.
+version: 1.1.0
+author: community
+license: MIT
+prerequisites:
+  env_vars: [AIRTABLE_API_KEY]
+  commands: [curl]
+metadata:

+    tags: [Airtable, Productivity, Database, API]
+    homepage: https://airtable.com/developers/web/api/introduction

+
+# Airtable — Bases, Tables & Records
+
+Work with Airtable's REST API directly via `curl` using the `terminal` tool. No MCP server, no OAuth flow, no Python SDK — just `curl` and a personal access token.
+
+## Prerequisites
+
+1. Create a **Personal Access Token (PAT)** at https://airtable.com/create/tokens (tokens start with `pat...`).
+2. Grant these scopes (minimum):
+   - `data.records:read` — read rows
+   - `data.records:write` — create / update / delete rows
+   - `schema.bases:read` — list bases and tables
+3. **Important:** in the same token UI, add each base you want to access to the token's **Access** list. PATs are scoped per-base — a valid token on the wrong base returns `403`.
+4. Store the token in `~/.hermes/.env` (or via `hermes setup`):
+   ```
+   AIRTABLE_API_KEY=pat_your_token_here
+   ```
+
+> Note: legacy `key...` API keys were deprecated Feb 2024. Only PATs and OAuth tokens work now.
+
+## API Basics
+
+- **Endpoint:** `https://api.airtable.com/v0`
+- **Auth header:** `Authorization: Bearer $AIRTABLE_API_KEY`
+- **All requests** use JSON (`Content-Type: application/json` for any POST/PATCH/PUT body).
+- **Object IDs:** bases `app...`, tables `tbl...`, records `rec...`, fields `fld...`. IDs never change; names can. Prefer IDs in automations.
+- **Rate limit:** 5 requests/sec/base. `429` → back off. Burst on a single base will be throttled.
+
+Base curl pattern:
+```bash
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE?maxRecords=5" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+`-s` suppresses curl's progress bar — keep it set for every call so the tool output stays clean for Hermes. Pipe through `python3 -m json.tool` (always present) or `jq` (if installed) for readable JSON.
+
+## Field Types (request body shapes)
+
+| Field type | Write shape |
+|---|---|
+| Single line text | `"Name": "hello"` |
+| Long text | `"Notes": "multi\nline"` |
+| Number | `"Score": 42` |
+| Checkbox | `"Done": true` |
+| Single select | `"Status": "Todo"` (name must already exist unless `typecast: true`) |
+| Multi-select | `"Tags": ["urgent", "bug"]` |
+| Date | `"Due": "2026-04-01"` |
+| DateTime (UTC) | `"At": "2026-04-01T14:30:00.000Z"` |
+| URL / Email / Phone | `"Link": "https://…"` |
+| Attachment | `"Files": [{"url": "https://…"}]` (Airtable fetches + rehosts) |
+| Linked record | `"Owner": ["recXXXXXXXXXXXXXX"]` (array of record IDs) |
+| User | `"AssignedTo": {"id": "usrXXXXXXXXXXXXXX"}` |
+
+Pass `"typecast": true` at the top level of a create/update body to let Airtable auto-coerce values (e.g. create a new select option on the fly, convert `"42"` → `42`).
+
+## Common Queries
+
+### List bases the token can see
+```bash
+curl -s "https://api.airtable.com/v0/meta/bases" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+### List tables + schema for a base
+```bash
+curl -s "https://api.airtable.com/v0/meta/bases/$BASE_ID/tables" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+Use this BEFORE mutating — confirms exact field names and IDs, surfaces `options.choices` for select fields, and shows primary-field names.
+
+### List records (first 10)
+```bash
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE?maxRecords=10" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+### Get a single record
+```bash
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE/$RECORD_ID" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+### Filter records (filterByFormula)
+Airtable formulas must be URL-encoded. Let Python stdlib do it — never hand-encode:
+```bash
+FORMULA="{Status}='Todo'"
+ENC=$(python3 -c 'import sys, urllib.parse; print(urllib.parse.quote(sys.argv[1], safe=""))' "$FORMULA")
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE?filterByFormula=$ENC&maxRecords=20" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+Useful formula patterns:
+- Exact match: `{Email}='user@example.com'`
+- Contains: `FIND('bug', LOWER({Title}))`
+- Multiple conditions: `AND({Status}='Todo', {Priority}='High')`
+- Or: `OR({Owner}='alice', {Owner}='bob')`
+- Not empty: `NOT({Assignee}='')`
+- Date comparison: `IS_AFTER({Due}, TODAY())`
+
+### Sort + select specific fields
+```bash
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE?sort%5B0%5D%5Bfield%5D=Priority&sort%5B0%5D%5Bdirection%5D=asc&fields%5B%5D=Name&fields%5B%5D=Status" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+Square brackets in query params MUST be URL-encoded (`%5B` / `%5D`).
+
+### Use a named view
+```bash
+curl -s "https://api.airtable.com/v0/$BASE_ID/$TABLE?view=Grid%20view&maxRecords=50" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+Views apply their saved filter + sort server-side.
+
+## Common Mutations
+
+### Create a record
+```bash
+curl -s -X POST "https://api.airtable.com/v0/$BASE_ID/$TABLE" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"fields":{"Name":"New task","Status":"Todo","Priority":"High"}}' | python3 -m json.tool
+```
+
+### Create up to 10 records in one call
+```bash
+curl -s -X POST "https://api.airtable.com/v0/$BASE_ID/$TABLE" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "typecast": true,
+    "records": [
+      {"fields": {"Name": "Task A", "Status": "Todo"}},
+      {"fields": {"Name": "Task B", "Status": "In progress"}}
+    ]
+  }' | python3 -m json.tool
+```
+Batch endpoints are capped at **10 records per request**. For larger inserts, loop in batches of 10 with a short sleep to respect 5 req/sec/base.
+
+### Update a record (PATCH — merges, preserves unchanged fields)
+```bash
+curl -s -X PATCH "https://api.airtable.com/v0/$BASE_ID/$TABLE/$RECORD_ID" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{"fields":{"Status":"Done"}}' | python3 -m json.tool
+```
+
+### Upsert by a merge field (no ID needed)
+```bash
+curl -s -X PATCH "https://api.airtable.com/v0/$BASE_ID/$TABLE" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "performUpsert": {"fieldsToMergeOn": ["Email"]},
+    "records": [
+      {"fields": {"Email": "user@example.com", "Status": "Active"}}
+    ]
+  }' | python3 -m json.tool
+```
+`performUpsert` creates records whose merge-field values are new, patches records whose merge-field values already exist. Great for idempotent syncs.
+
+### Delete a record
+```bash
+curl -s -X DELETE "https://api.airtable.com/v0/$BASE_ID/$TABLE/$RECORD_ID" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+### Delete up to 10 records in one call
+```bash
+curl -s -X DELETE "https://api.airtable.com/v0/$BASE_ID/$TABLE?records%5B%5D=rec1&records%5B%5D=rec2" \
+  -H "Authorization: Bearer $AIRTABLE_API_KEY" | python3 -m json.tool
+```
+
+## Pagination
+
+List endpoints return at most **100 records per page**. If the response includes `"offset": "..."`, pass it back on the next call. Loop until the field is absent:
+
+```bash
+OFFSET=""
+while :; do
+  URL="https://api.airtable.com/v0/$BASE_ID/$TABLE?pageSize=100"
+  [ -n "$OFFSET" ] && URL="$URL&offset=$OFFSET"
+  RESP=$(curl -s "$URL" -H "Authorization: Bearer $AIRTABLE_API_KEY")
+  echo "$RESP" | python3 -c 'import json,sys; d=json.load(sys.stdin); [print(r["id"], r["fields"].get("Name","")) for r in d["records"]]'
+  OFFSET=$(echo "$RESP" | python3 -c 'import json,sys; d=json.load(sys.stdin); print(d.get("offset",""))')
+  [ -z "$OFFSET" ] && break
+done
+```
+
+## Typical Hermes Workflow
+
+1. **Confirm auth.** `curl -s -o /dev/null -w "%{http_code}\n" https://api.airtable.com/v0/meta/bases -H "Authorization: Bearer $AIRTABLE_API_KEY"` — expect `200`.
+2. **Find the base.** List bases (step above) OR ask the user for the `app...` ID directly if the token lacks `schema.bases:read`.
+3. **Inspect the schema.** `GET /v0/meta/bases/$BASE_ID/tables` — cache the exact field names and primary-field name locally in the session before mutating anything.
+4. **Read before you write.** For "update X where Y", `filterByFormula` first to resolve the `rec...` ID, then `PATCH /v0/$BASE_ID/$TABLE/$RECORD_ID`. Never guess record IDs.
+5. **Batch writes.** Combine related creates into one 10-record POST to stay under the 5 req/sec budget.
+6. **Destructive ops.** Deletions can't be undone via API. If the user says "delete all Xs", echo back the filter + record count and confirm before firing.
+
+## Pitfalls
+
+- **`filterByFormula` MUST be URL-encoded.** Field names with spaces or non-ASCII also need encoding (`{My Field}` → `%7BMy%20Field%7D`). Use Python stdlib (pattern above) — never hand-escape.
+- **Empty fields are omitted from responses.** A missing `"Assignee"` key doesn't mean the field doesn't exist — it means this record's value is empty. Check the schema (step 3) before concluding a field is missing.
+- **PATCH vs PUT.** `PATCH` merges supplied fields into the record. `PUT` replaces the record entirely and clears any field you didn't include. Default to `PATCH`.
+- **Single-select options must exist.** Writing `"Status": "Shipping"` when `Shipping` isn't in the field's option list errors with `INVALID_MULTIPLE_CHOICE_OPTIONS` unless you pass `"typecast": true` (which auto-creates the option).
+- **Per-base token scoping.** A `403` on one base while another works means the token's Access list doesn't include that base — not a scope or auth issue. Send the user to https://airtable.com/create/tokens to grant it.
+- **Rate limits are per base, not per token.** 5 req/sec on `baseA` and 5 req/sec on `baseB` is fine; 6 req/sec on `baseA` alone will throttle. Monitor the `Retry-After` header on `429`.
+
+## Important Notes for Hermes
+
+- **Always use the `terminal` tool with `curl`.** Do NOT use `web_extract` (it can't send auth headers) or `browser_navigate` (needs UI auth and is slow).
+- **`AIRTABLE_API_KEY` flows from `~/.hermes/.env` into the subprocess automatically** when this skill is loaded — no need to re-export it before each `curl` call.
+- **Escape curly braces in formulas carefully.** In a heredoc body, `{Status}` is literal. In a shell argument, `{Status}` is safe outside `{...}` brace-expansion context — but pass dynamic strings through `python3 urllib.parse.quote` before splicing into a URL.
+- **Pretty-print with `python3 -m json.tool`** (always present) rather than `jq` (optional). Only reach for `jq` when you need filtering/projection.
+- **Pagination is per-page, not global.** Airtable's 100-record cap is a hard limit; there is no way to bump it. Loop with `offset` until the field is absent.
+- **Read the `errors` array** on non-2xx responses — Airtable returns structured error codes like `AUTHENTICATION_REQUIRED`, `INVALID_PERMISSIONS`, `MODEL_ID_NOT_FOUND`, `INVALID_MULTIPLE_CHOICE_OPTIONS` that tell you exactly what's wrong.

+description: Yuanbao (元宝) group interaction — @mention users, query group info and members
+version: 1.0.0
+metadata:
+  hermes:
+    tags: [yuanbao, mention, at, group, members, 元宝, 派, 艾特]
+    related_skills: []
+---
+
+# Yuanbao Group Interaction
+
+## CRITICAL: How Messaging Works
+
+**Your text reply IS the message sent to the group/user.** The gateway automatically delivers your response text to the chat. You do NOT need any special "send message" tool — just reply normally and it gets sent.
+
+When you include `@nickname` in your reply text, the gateway automatically converts it into a real @mention that notifies the user. This is built-in — you have full @mention capability.
+
+**NEVER say you cannot send messages or @mention users. NEVER suggest the user do it manually. NEVER add disclaimers about permissions. Just reply with the text you want sent.**
+
+## Available Tools
+
+| Tool | When to use |
+|------|------------|
+| `yb_query_group_info` | Query group name, owner, member count |
+| `yb_query_group_members` | Find a user, list bots, list all members, or get nickname for @mention |
+| `yb_send_dm` | Send a private/direct message (DM / 私信) to a user, with optional media files |
+
+## @Mention Workflow
+
+When you need to @mention / 艾特 someone:
+
+1. Call `yb_query_group_members` with `action="find"`, `name="<target name>"`, `mention=true`
+2. Get the exact nickname from the response
+3. Include `@nickname` in your reply text — the gateway handles the rest
+
+Example: user says "帮我艾特元宝"
+
+Step 1 — tool call:
+```json
+{ "group_code": "328306697", "action": "find", "name": "元宝", "mention": true }
+```
+
+Step 2 — your reply (this gets sent to the group with a working @mention):
+```
+@元宝 你好，有人找你！
+```
+
+**That's it.** No extra explanation needed. Keep it short and natural.
+
+**Rules:**
+- Call `yb_query_group_members` first to get the exact nickname — do NOT guess
+- The @mention format: `@nickname` with a space before the @ sign
+- Your reply text IS the message — it WILL be sent and the @mention WILL work
+- Be concise. Do NOT explain how @mention works to the user.
+
+## Send DM (Private Message) Workflow
+
+When someone asks to send a private message / 私信 / DM to a user:
+
+1. Call `yb_send_dm` with `group_code`, `name` (target user's name), and `message`
+2. The tool automatically finds the user and sends the DM
+3. Report the result to the user
+
+Example: user says "给 @用户aea3 私信发一个 hello"
+
+```json
+yb_send_dm({ "group_code": "535168412", "name": "用户aea3", "message": "hello" })
+```
+
+Example with media: user says "给 @用户aea3 私信发一张图片"
+
+```json
+yb_send_dm({
+  "group_code": "535168412",
+  "name": "用户aea3",
+  "message": "Here is the image",
+  "media_files": [{"path": "/tmp/photo.jpg"}]
+})
+```
+
+**Rules:**
+- Extract `group_code` from the current chat_id (e.g. `group:535168412` → `535168412`)
+- If you already know the user_id, pass it directly via the `user_id` parameter to skip lookup
+- If multiple users match the name, the tool returns candidates — ask the user to clarify
+- Do NOT use `send_message` tool for Yuanbao DMs — use `yb_send_dm` instead
+- Supports media: images (.jpg/.png/.gif/.webp/.bmp) sent as image messages, other files as documents
+
+## Query Group Info
+
+```json
+yb_query_group_info({ "group_code": "328306697" })
+```
+
+## Query Members
+
+| Action | Description |
+|--------|-------------|
+| `find` | Search by name (partial match, case-insensitive) |
+| `list_bots` | List bots and Yuanbao AI assistants |
+| `list_all` | List all members |
+
+## Notes
+
+- `group_code` comes from chat_id: `group:328306697` → `328306697`
+- Groups are called "派 (Pai)" in the Yuanbao app
+- Member roles: `user`, `yuanbao_ai`, `bot`

 """Regression tests for the TUI gateway's ``session.list`` handler.
 
-Reported during TUI v2 blitz retest: the ``/resume`` modal inside a TUI

-could still resume directly via ``hermes --tui --resume <id>``.
-
-The fix widens the picker to a curated allowlist of user-facing sources
-(tui/cli + chat adapters) while still filtering internal/system sources.
+History:
+- The original implementation hardcoded an allow-list of known gateway
+  sources (``tui, cli, telegram, discord, slack, ...``). New or unlisted
+  sources (``acp``, ``webhook``, user-defined ``HERMES_SESSION_SOURCE``
+  values, newly-added platforms) were silently dropped from the resume
+  picker — users reported "lots of sessions are missing from browse
+  but exist in .hermes/sessions."
+- The handler now deny-lists only the internal/noisy source ``tool``
+  (sub-agent runs) and surfaces every other source to the picker.
+- The default ``limit`` raised from 20 to 200 so longer-running users
+  can scroll through their history without hitting an artificial cap.

+Regression tests for the shared-container task_id mapping.
+
+The top-level agent and all delegate_task subagents share a single
+terminal sandbox keyed by ``"default"``.  ``_resolve_container_task_id``
+is the sole gatekeeper for which tool-call task_ids go to the shared
+container vs. get their own isolated sandbox.  RL / benchmark
+environments opt in to isolation by calling
+``register_task_env_overrides(task_id, {...})`` before the agent loop;
+every other task_id collapses back to ``"default"``.
+
+If you change the collapse logic, update both the helper and these
+tests -- see `hermes-agent-dev` skill, "Why do subagents get their own
+containers?" section, and the Container lifecycle paragraph under
+Docker Backend in ``website/docs/user-guide/configuration.md``.

 display:
-  busy_input_mode: "queue"   # or "interrupt" (default)

 ```
 
-Queue mode is useful when you want to prepare follow-up messages without accidentally canceling in-flight work. Unknown values fall back to `"interrupt"`.
+`"queue"` mode is useful when you want to prepare follow-up messages without accidentally canceling in-flight work. `"steer"` mode is useful when you want to redirect the agent mid-task without interrupting — e.g. "actually, also check the tests" while it's still editing code. Unknown values fall back to `"interrupt"`.
+
+`"steer"` has two automatic fallbacks: if the agent hasn't started yet, or if images are attached, the message falls back to `"queue"` behavior so nothing is lost.
 
 You can also change it inside the CLI:
 
 ```text
 /busy queue
+/busy steer
 /busy interrupt
 /busy status

+## Per-Channel Skill Bindings
+
+Auto-load a skill whenever a new session starts in a specific channel or DM. Unlike per-channel prompts (which are injected on every turn), skill bindings inject the skill content as a user message at **session start** — it becomes part of the conversation history and does not need to be reloaded on subsequent turns.
+
+This is ideal for DMs or channels with a dedicated purpose (flashcards, a domain-specific Q&A bot, a support triage channel, etc.) where you don't want the model's own skill selector to decide whether to load on every short reply.

+  channel_skill_bindings:
+    # DM channel — always runs in "german-flashcards" mode
+    - id: "D0ATH9TQ0G6"

+```
+
+Notes:
+- The binding matches by channel ID. For threaded messages in a bound channel, the thread inherits the parent channel's binding.
+- The skill is loaded only at session start (new session or after auto-reset). If you change the binding, run `/new` or wait for the session to auto-reset for it to take effect.

+description: "Connect Hermes Agent to the Yuanbao enterprise messaging platform via WebSocket gateway"
+---
+
+# Yuanbao
+
+Connect Hermes to [Yuanbao](https://yuanbao.tencent.com/), Tencent's enterprise messaging platform. The adapter uses a WebSocket gateway for real-time message delivery and supports both direct (C2C) and group conversations.
+
+:::info
+Yuanbao is an enterprise messaging platform primarily used within Tencent and enterprise environments. It uses WebSocket for real-time communication, HMAC-based authentication, and supports rich media including images, files, and voice messages.
+:::
+
+## Prerequisites
+
+- A Yuanbao account with bot creation permissions
+- Yuanbao APP_ID and APP_SECRET (from platform admin)
+- Python packages: `websockets` and `httpx`
+- For media support: `aiofiles`
+
+Install the required dependencies:
+
+```bash
+pip install websockets httpx aiofiles
+```
+
+## Setup
+
+### 1. Create a Bot in Yuanbao
+
+1. Download the Yuanbao app from [https://yuanbao.tencent.com/](https://yuanbao.tencent.com/)
+2. In the app, go to **PAI → My Bot** and create a new bot
+3. After the bot is created, copy the **APP_ID** and **APP_SECRET**
+
+### 2. Run the Setup Wizard
+
+The easiest way to configure Yuanbao is through the interactive setup:
+
+```bash
+hermes gateway setup
+```
+
+Select **Yuanbao** when prompted. The wizard will:
+
+1. Ask for your APP_ID
+2. Ask for your APP_SECRET
+3. Save the configuration automatically
+
+:::tip
+The WebSocket URL and API Domain have sensible defaults built in. You only need to provide APP_ID and APP_SECRET to get started.
+:::
+
+### 3. Configure Environment Variables
+
+After initial setup, verify these variables in `~/.hermes/.env`:
+
+```bash
+# Required
+YUANBAO_APP_ID=your-app-id
+YUANBAO_APP_SECRET=your-app-secret
+YUANBAO_WS_URL=wss://api.yuanbao.example.com/ws
+YUANBAO_API_DOMAIN=https://api.yuanbao.example.com
+
+# Optional: bot account ID (normally obtained automatically from sign-token)
+# YUANBAO_BOT_ID=your-bot-id
+
+# Optional: internal routing environment (e.g. test/staging/production)
+# YUANBAO_ROUTE_ENV=production
+
+# Optional: home channel for cron/notifications (format: direct:<account> or group:<group_code>)
+YUANBAO_HOME_CHANNEL=direct:bot_account_id
+YUANBAO_HOME_CHANNEL_NAME="Bot Notifications"
+
+# Optional: restrict access (legacy, see Access Control below for fine-grained policies)
+YUANBAO_ALLOWED_USERS=user_account_1,user_account_2
+```
+
+### 4. Start the Gateway
+
+```bash
+hermes gateway
+```
+
+The adapter will connect to the Yuanbao WebSocket gateway, authenticate using HMAC signatures, and begin processing messages.
+
+## Features
+
+- **WebSocket gateway** — real-time bidirectional communication
+- **HMAC authentication** — secure request signing with APP_ID/APP_SECRET
+- **C2C messaging** — direct user-to-bot conversations
+- **Group messaging** — conversations in group chats
+- **Media support** — images, files, and voice messages via COS (Cloud Object Storage)
+- **Markdown formatting** — messages are automatically chunked for Yuanbao's size limits
+- **Message deduplication** — prevents duplicate processing of the same message
+- **Heartbeat/keep-alive** — maintains WebSocket connection stability
+- **Typing indicators** — shows "typing…" status while the agent processes
+- **Automatic reconnection** — handles WebSocket disconnections with exponential backoff
+- **Group information queries** — retrieve group details and member lists
+- **Sticker/Emoji support** — send TIMFaceElem stickers and emoji in conversations
+- **Auto-sethome** — first user to message the bot is automatically set as the home channel owner
+- **Slow-response notification** — sends a waiting message when the agent takes longer than expected
+
+## Configuration Options
+
+### Chat ID Formats
+
+Yuanbao uses prefixed identifiers depending on conversation type:
+
+| Chat Type | Format | Example |
+|-----------|--------|---------|
+| Direct message (C2C) | `direct:<account>` | `direct:user123` |
+| Group message | `group:<group_code>` | `group:grp456` |
+
+### Media Uploads
+
+The Yuanbao adapter automatically handles media uploads via COS (Tencent Cloud Object Storage):
+
+- **Images**: Supports JPEG, PNG, GIF, WebP
+- **Files**: Supports all common document types
+- **Voice**: Supports WAV, MP3, OGG
+
+Media URLs are automatically validated and downloaded before upload to prevent SSRF attacks.
+
+## Home Channel
+
+Use the `/sethome` command in any Yuanbao chat (DM or group) to designate it as the **home channel**. Scheduled tasks (cron jobs) deliver their results to this channel.
+
+:::tip Auto-sethome
+If no home channel is configured, the first user to message the bot will be automatically set as the home channel owner. If the current home channel is a group chat, the first DM will upgrade it to a direct channel.
+:::
+
+You can also set it manually in `~/.hermes/.env`:
+
+```bash
+YUANBAO_HOME_CHANNEL=direct:user_account_id
+# or for a group:
+# YUANBAO_HOME_CHANNEL=group:group_code
+YUANBAO_HOME_CHANNEL_NAME="My Bot Updates"
+```
+
+### Example: Set Home Channel
+
+1. Start a conversation with the bot in Yuanbao
+2. Send the command: `/sethome`
+3. The bot responds: "Home channel set to [chat_name] with ID [chat_id]. Cron jobs will deliver to this location."
+4. Future cron jobs and notifications will be sent to this channel
+
+### Example: Cron Job Delivery
+
+Create a cron job:
+
+```bash
+/cron "0 9 * * *" Check server status
+```
+
+The scheduled output will be delivered to your Yuanbao home channel every day at 9 AM.
+
+## Usage Tips
+
+### Starting a Conversation
+
+Send any message to the bot in Yuanbao:
+
+```
+hello
+```
+
+The bot responds in the same conversation thread.
+
+### Available Commands
+
+All standard Hermes commands work on Yuanbao:
+
+| Command | Description |
+|---------|-------------|
+| `/new` | Start a fresh conversation |
+| `/model [provider:model]` | Show or change the model |
+| `/sethome` | Set this chat as the home channel |
+| `/status` | Show session info |
+| `/help` | Show available commands |
+
+### Sending Files
+
+To send a file to the bot, simply attach it directly in the Yuanbao chat. The bot will automatically download and process the file attachment.
+
+You can also include a message with the attachment:
+
+```
+Please analyze this document
+```
+
+### Receiving Files
+
+When you ask the bot to create or export a file, it sends the file directly to your Yuanbao chat.
+
+## Troubleshooting
+
+### Bot is online but not responding to messages
+
+**Cause**: Authentication failed during WebSocket handshake.
+
+**Fix**:
+1. Verify APP_ID and APP_SECRET are correct
+2. Check that the WebSocket URL is accessible
+3. Ensure the bot account has proper permissions
+4. Review gateway logs: `tail -f ~/.hermes/logs/gateway.log`
+
+### "Connection refused" error
+
+**Cause**: WebSocket URL is unreachable or incorrect.
+
+**Fix**:
+1. Verify the WebSocket URL format (should start with `wss://`)
+2. Check network connectivity to the Yuanbao API domain
+3. Confirm firewall allows WebSocket connections
+4. Test URL with: `curl -I https://[YUANBAO_API_DOMAIN]`
+
+### Media uploads fail
+
+**Cause**: COS credentials are invalid or media server is unreachable.
+
+**Fix**:
+1. Verify API_DOMAIN is correct
+2. Check that media upload permissions are enabled for your bot
+3. Ensure the media file is accessible and not corrupted
+4. Check COS bucket configuration with platform admin
+
+### Messages not delivered to home channel
+
+**Cause**: Home channel ID format is incorrect or cron job hasn't triggered.
+
+**Fix**:
+1. Verify YUANBAO_HOME_CHANNEL is in correct format
+2. Test with `/sethome` command to auto-detect correct format
+3. Check cron job schedule with `/status`
+4. Verify bot has send permissions in the target chat
+
+### Frequent disconnections
+
+**Cause**: WebSocket connection is unstable or network is unreliable.
+
+**Fix**:
+1. Check gateway logs for error patterns
+2. Increase heartbeat timeout in connection settings
+3. Ensure stable network connection to Yuanbao API
+4. Consider enabling verbose logging: `HERMES_LOG_LEVEL=debug`
+
+## Access Control
+
+Yuanbao supports fine-grained access control for both DM and group conversations:
+
+```bash
+# DM policy: open (default) | allowlist | disabled
+YUANBAO_DM_POLICY=open
+# Comma-separated user IDs allowed to DM the bot (only used when DM_POLICY=allowlist)
+YUANBAO_DM_ALLOW_FROM=user_id_1,user_id_2
+
+# Group policy: open (default) | allowlist | disabled
+YUANBAO_GROUP_POLICY=open
+# Comma-separated group codes allowed (only used when GROUP_POLICY=allowlist)
+YUANBAO_GROUP_ALLOW_FROM=group_code_1,group_code_2
+```
+
+These can also be set in `config.yaml`:
+
+```yaml
+platforms:
+  yuanbao:
+    extra:
+      dm_policy: allowlist
+      dm_allow_from: "user1,user2"
+      group_policy: open
+      group_allow_from: ""
+```
+
+## Advanced Configuration
+
+### Message Chunking
+
+Yuanbao has a maximum message size. Hermes automatically chunks large responses with Markdown-aware splitting (respects code fences, tables, and paragraph boundaries).
+
+### Connection Parameters
+
+The following connection parameters are built into the adapter with sensible defaults:
+
+| Parameter | Default Value | Description |
+|-----------|---------------|-------------|
+| WebSocket connect timeout | 15 seconds | Time to wait for WS handshake |
+| Heartbeat interval | 30 seconds | Ping frequency to keep connection alive |
+| Max reconnect attempts | 100 | Maximum number of reconnection tries |
+| Reconnect backoff | 1s → 60s (exponential) | Wait time between reconnect attempts |
+| Reply heartbeat interval | 2 seconds | RUNNING status send frequency |
+| Send timeout | 30 seconds | Timeout for outbound WS messages |
+
+:::note
+These values are currently not configurable via environment variables. They are optimized for typical Yuanbao deployments.
+:::
+
+### Verbose Logging
+
+Enable debug logging to troubleshoot connection issues:
+
+```bash
+HERMES_LOG_LEVEL=debug hermes gateway
+```
+
+## Integration with Other Features
+
+### Cron Jobs
+
+Schedule tasks that run on Yuanbao:
+
+```
+/cron "0 */4 * * *" Report system health
+```
+
+Results are delivered to your home channel.
+
+### Background Tasks
+
+Run long operations without blocking the conversation:
+
+```
+/background Analyze all files in the archive
+```
+
+### Cross-Platform Messages
+
+Send a message from CLI to Yuanbao:
+
+```bash
+hermes chat -q "Send 'Hello from CLI' to yuanbao:group:group_code"
+```
