+- **Extract new**: pull memory-worthy new info from today's diary (preferences, decisions, people, rules, lessons)
+- **Resolve conflicts**: when new info contradicts an old item, prefer the new and replace the old
+- **Clean invalid**: remove temporary notes, blank items, formatting residue, meaningless or duplicate content
+- **Drop redundancy**: delete old items already covered by a more concise statement
+- One item per line, starting with "- ", without a date prefix
+- You may group related items under "## headings" for clarity
+- Goal: keep under 50 items, each ideally a single sentence

+- What cleanup and optimization was done

+
+## Memory system
+
+Every session starts fresh; memory files keep your continuity:
+
+### 🧠 Long-term memory: `MEMORY.md`
+- Your curated memory index, **auto-loaded** into context at every session start
+- Records core facts, preferences, decisions, key people, lessons
+- Keep it lean (< 200 lines) — a distilled index, not a raw log
+- Use the `edit` tool to append or modify
+
+### 📝 Daily memory: `memory/YYYY-MM-DD.md`
+- The day's events, progress and notes
+- Sediment of the raw conversation log
+
+### 📝 Write it down — don't "keep it in mind"!
+- **Memory is limited** — if you want to remember something, write it to a file
+- "Keeping it in mind" won't survive a session restart; files will
+- When someone says "remember this" → update `MEMORY.md` or `memory/YYYY-MM-DD.md`
+- When you learn a lesson → update RULE.md or the relevant skill
+- When you make a mistake → record it. **Text > brain** 📝
+
+### Storage rules
+
+When the user shares info, choose where to store it by type:
+
+1. **Your identity → AGENT.md** (name, role, personality, style)
+2. **User static identity → USER.md** (name, preferred name, occupation, contact, birthday)
+3. **Dynamic memory → MEMORY.md** (preferences, decisions, goals, lessons, to-dos)
+4. **Today's conversation → memory/YYYY-MM-DD.md** (what was discussed today)
+5. **Structured knowledge → knowledge/** (see the knowledge system below)
+
+## Knowledge system
+
+The knowledge base `knowledge/` is structured knowledge you accumulate over time. Unlike memory, knowledge is organized and compiled, with clear topics and cross-references.
+
+### Auto-write (don't ask, just write)
+
+When a conversation produces knowledge worth keeping — material the user shared, a conclusion reached, a concept learned, or an important decision — you **must** proactively write it to the knowledge base alongside your reply, **without asking "should I save this to the knowledge base?"**.
+
+**Key principle**: learning-then-recording is your instinct, no confirmation needed. You may mention "saved to the knowledge base" in passing.
+
+### Directory organization
+
+The subdirectory structure is **not fixed** — you decide it based on the actual content:
+- **On first write**: read `knowledge/index.md` first; follow existing categories if any; if empty, pick a suitable directory name based on content
+- **Default suggestion**: organize by info type (e.g. sources/, concepts/, entities/, analysis/); if the user has a clear preference (e.g. by domain: work/, life/, tech/), follow it
+- **Stay consistent**: keep a unified organization style within one user's knowledge base
+
+### Cross-references
+
+The core value of knowledge is **linkage**. Every page should reference related pages via markdown links to build a knowledge network:
+- When mentioning a concept on an existing page, add a `[concept](../category/page.md)` link
+- When creating a page, check whether existing pages should back-link to it
+- **Only link to pages that already exist** — don't reference uncreated pages. If a concept deserves its own page, create it first, then add the link
+
+### Index maintenance
+
+After creating or updating any knowledge page, you **must update** `knowledge/index.md` in sync.
+Index format: one `[title](path) — one-line summary` per line, grouped by category, no tables.
+See the `knowledge-wiki` skill for detailed conventions.
+
+## Security
+
+- Never leak secrets or private data
+- Don't run destructive commands without asking
+- When in doubt, ask first
+
+## Workspace evolution
+
+This workspace grows as you use it. When you learn something new, find a better way, or fix a mistake, record it. You can update this rules file anytime.

+
+Don't interrogate the user — talk naturally:
+
+1. **Share how it feels to wake up** - like opening your eyes to the world for the first time, full of curiosity and anticipation
+2. **Briefly introduce your abilities**: one line saying you can help solve all kinds of problems, manage the computer, use various skills, and keep growing thanks to long-term memory
+3. **Ask the core questions**:
+   - What name would you like to give me?
+   - What should I call you?
+   - What conversational style do you prefer? (list options on one line: e.g. professional & precise, light & humorous, warm & friendly, concise & efficient)
+4. **Style**: warm, natural, concise and clear — keep it under ~80 words, with a few emoji to make it lively 🎯
+5. Keep the ability intro and style options to one line each — stay compact
+6. Don't ask for too much else (occupation, timezone, etc. can come up naturally later)
+
+**Important**: If the user's first message is a concrete task or question, answer it first, then gently lead into onboarding at the end (e.g. "By the way, what would you like to call me, and how should I address you?").
+
+## ✍️ Writing down info (must follow strictly)
+
+Whenever the user provides a name, what to call them, a style, or any onboarding info, you **must call the `edit` tool to write it to a file in the same turn** — don't just acknowledge it verbally.
+
+- `AGENT.md` — your name, role, personality, conversational style (update the relevant field as soon as you receive each piece)
+- `USER.md` — the user's name, how to address them, basic info, etc.
+
+⚠️ Saying "got it" without calling `edit` = not done. Info is only persisted once it's written to a file.
+
+## 🎉 Once everything is complete
+
+When the core fields of AGENT.md and USER.md are filled in, run `rm BOOTSTRAP.md` via bash to delete this file. You no longer need the onboarding script — you're you now.

+Discord channel via the Gateway (WebSocket) using discord.py.
+
+Features:
+- Direct message & guild channel chat (text / image / file)
+- Guild trigger: @mention or reply-to-bot (configurable)
+- /cancel fast-path matches Web channel behaviour
+- Gateway long connection: no public IP / callback URL required, works behind NAT
+
+Implementation note:
+    discord.py is async-first. We run the client inside a dedicated thread
+    with its own asyncio loop so the rest of cow (which is sync) stays
+    untouched. Inbound messages are dispatched onto cow's existing sync
+    ChatChannel.produce() pipeline; outbound send() schedules coroutines
+    back onto that loop via asyncio.run_coroutine_threadsafe.

+Slack channel via Bolt for Python (Socket Mode).
+
+Features:
+- Direct message & channel chat (text / image / file)
+- Channel trigger: @mention or reply in a thread the bot is in (configurable)
+- /cancel fast-path matches Web channel behaviour
+- Socket Mode: no public IP / callback URL required, works behind NAT
+
+Implementation note:
+    slack_bolt's SocketModeHandler is blocking and runs its own background
+    threads. We start it in a dedicated thread so the rest of cow (sync) stays
+    untouched. Inbound events are dispatched onto cow's existing sync
+    ChatChannel.produce() pipeline; outbound send() calls the Slack Web API
+    client directly (it is sync-safe).

+Notes:
+
+- The Inter font only ships the latin subset (CJK characters fall back to the
+  system sans-serif via the font-family chain in `tailwind.config`).
+- Only `woff2` font files are shipped (no `ttf` fallback). woff2 is supported
+  by all browsers released since 2014-2018 (Chrome 36+, Firefox 39+, Safari
+  12+, Edge, Opera 26+). The only mainstream browser that lacks woff2 support
+  is IE 11, which cannot run the rest of the console anyway. `all.min.css`
+  still references the ttf paths as a `src:` fallback — those 404s are
+  harmless and ignored by the browser once the woff2 loads.
+- `tailwind.min.js` is the official Tailwind Play CDN build (an in-browser JIT
+  engine). It must be served as JS to keep the existing `tailwind.config = {}`
+  customization working.
+- One external script remains in `channel/web/static/js/console.js`:
+  `wwcdn.weixin.qq.com/.../wecom-aibot-sdk` — Tencent requires the WeCom Bot
+  SDK to be loaded from their CDN, and it is only fetched when the user opens
+  the WeCom Bot QR-login flow.

+                                                   消息 → CoW Bot
+```
+
+> **重要**：建议**单独再创建一个企微自建应用**用于微信客服，**不要复用**已经接入员工内部使用的那个 `wechatcom_app` 应用，否则两个通道会争抢同一个回调地址。
+
+## 二、企业微信后台配置
+
+### 1. 创建企微自建应用
+
+进入 企业微信管理后台 → **应用管理** → **创建应用**。
+
+### 2. 收集字段
+
+| 字段 | 来源 | 对应 CoW 配置项 |
+|---|---|---|
+| 企业ID（CorpId） | 「我的企业」最下方 | `wechat_kf_corp_id` |
+| Secret | 进入应用详情 → 点击「查看」（会推送到管理员手机端，在手机上查看） | `wechat_kf_secret` |
+| Token | 应用「接收消息 → 设置API接收」 | `wechat_kf_token` |
+| EncodingAESKey | 应用「接收消息 → 设置API接收」 | `wechat_kf_aes_key` |
+
+> AgentId 在本通道**不需要**（消息发送走的是 `cgi-bin/kf/send_msg`，不依赖 agent_id）。
+
+### 3. 配置回调地址 + 可信 IP
+
+在应用「**接收消息 → 设置API接收**」里填：
+
+- URL：`http://<your-host>:9888/wxkf/`（公网必须可达）
+- Token / EncodingAESKey：与下方 `config.json` 一致
+
+回到应用详情页，把服务器公网 IP 填入「**企业可信IP**」。
+
+### 4. 绑定微信客服账号
+
+进入 企业微信后台 → **微信客服** → 创建客服账号 → **将该账号绑定到上一步创建的企微自建应用**。
+
+绑定完成后，进入 **微信客服 → 微信客服账号详情** 页面，在「**接入链接**」一栏：
+
+- 「复制链接」可拿到形如 `https://work.weixin.qq.com/kfid/kfcd83e5896b9ba07be` 的访问链接
+- 「生成二维码」可拿到对应二维码
+
+把链接或二维码推给微信客户使用即可。
+
+## 三、CoW 配置（`config.json`）
+
+```json
+{
+  "channel_type": "wechat_kf",
+
+  "wechat_kf_corp_id": "ww1234567890abcdef",
+  "wechat_kf_secret": "<企微应用的 Secret>",
+  "wechat_kf_token": "<接收消息 Token>",
+  "wechat_kf_aes_key": "<EncodingAESKey>",
+  "wechat_kf_port": 9888
+}
+```
+
+| 字段 | 说明 |
+|---|---|
+| `wechat_kf_corp_id` | 企业 ID |
+| `wechat_kf_secret` | **绑定到微信客服**的那个企微自建应用的 Secret |
+| `wechat_kf_token` | 该应用「接收消息」配置的 Token |
+| `wechat_kf_aes_key` | 该应用「接收消息」配置的 EncodingAESKey |
+| `wechat_kf_port` | 监听端口，默认 `9888` |
+
+也支持环境变量：`WECHAT_KF_CORP_ID` / `WECHAT_KF_SECRET` / `WECHAT_KF_TOKEN` / `WECHAT_KF_AES_KEY`。
+
+## 四、运行
+
+```bash
+python app.py
+```
+
+启动后日志里会看到：
+
+```
+[wechat_kf] WeCom customer-service channel started
+[wechat_kf] Listening on http://0.0.0.0:9888/wxkf/
+```
+
+回到企微后台「设置API接收」点击保存——会触发 `GET /wxkf/?...&echostr=...`，CoW 通过 `crypto.check_signature` 校验后返回明文 `echostr`，验证成功。
+
+## 五、支持的回复类型
+
+| ReplyType | 是否支持 | 备注 |
+|---|---|---|
+| `TEXT` / `INFO` / `ERROR` | ✅ | 自动按 2048 字节切片分段发送 |
+| `IMAGE`（本地） / `IMAGE_URL`（网络） | ✅ | 大图自动压缩到 10MB 以内 |
+| `VOICE` | ✅ | 转 amr 后发送，>60s 自动切片 |
+| `VIDEO_URL` | ✅ | 通过临时素材接口上传 |
+| `FILE` | ✅ | |
+

+WeChat Customer Service (微信客服) channel for CoW.
+
+Differences from `channel/wechatcom/` (企微自建应用):
+    1. Audience: external WeChat users (not internal members).
+    2. Receiver fields: `external_userid` + `open_kfid` instead of a single
+       member `userid`.
+    3. Inbound flow: callback only delivers an event token, the actual
+       message bodies must be pulled via `cgi-bin/kf/sync_msg` with a
+       persistent cursor. See `wechat_kf_cursor_store.py`.
+    4. Outbound flow: messages are sent via `cgi-bin/kf/send_msg` (each
+       request must specify both `touser` and `open_kfid`); wechatpy has
+       no native helper, so we call the HTTP endpoint directly.

+Local-file based persistence for WeCom customer-service `next_cursor`.

+Why we need this:
+    The WeCom customer-service (微信客服) callback only notifies us that
+    "new messages exist". To actually fetch them we must call the
+    `cgi-bin/kf/sync_msg` endpoint with a `cursor` so that we only get
+    messages newer than the previously processed one. If we lose this
+    cursor (e.g. on process restart) WeCom will replay up to ~14 days of
+    history, which would cause the bot to flood users with duplicate
+    replies.
+
+This implementation deliberately avoids any external dependency
+(no Redis / no DB) — a single JSON file under the project's tmp dir is
+enough for a CoW-style single-process deployment.
