Recommended WeChat Chat Export Tools
These are independent open-source projects — this project does not include their code, but our parsers are compatible with their export formats. WeChat auto-decryption is currently unstable, so we recommend using these open-source tools to export chat history, then paste or import into this project:
| Tool | Platform | Description |
|---|---|---|
| WeChatMsg | Windows | WeChat chat history export, supports multiple formats |
| PyWxDump | Windows | WeChat database decryption & export |
| 留痕 (Liuhen) | macOS | WeChat chat history export (recommended for Mac users) |
Tool recommendations from @therealXiaomanChu. Thanks to all the open-source authors — together for cyber-immortality!
Install
Claude Code
Important: Claude Code looks for skills in
.claude/skills/at the git repo root. Make sure you run this in the right place.
# Install to current project (run at git repo root)
mkdir -p .claude/skills
git clone https://github.com/titanwings/colleague-skill .claude/skills/create-colleague
# Or install globally (available in all projects)
git clone https://github.com/titanwings/colleague-skill ~/.claude/skills/create-colleague
OpenClaw
git clone https://github.com/titanwings/colleague-skill ~/.openclaw/workspace/skills/create-colleague
Dependencies (optional)
pip3 install -r requirements.txt
Feishu/DingTalk/Slack auto-collection requires App credentials. See INSTALL.md for details.
Usage
In Claude Code, type:
/create-colleague
Follow the prompts: enter an alias, company/level (e.g. ByteDance L2-1 backend engineer), personality tags, then choose a data source. All fields can be skipped — even a description alone can generate a Skill.
Once created, invoke the colleague Skill with /{slug}.
Commands
| Command | Description |
|---|---|
/list-colleagues | List all colleague Skills |
/{slug} | Invoke full Skill (Persona + Work) |
/{slug}-work | Work capabilities only |
/{slug}-persona | Persona only |
/colleague-rollback {slug} {version} | Rollback to a previous version |
/delete-colleague {slug} | Delete |
Demo
Input:
ByteDance L2-1 backend engineer, INTJ, blame-shifter, ByteDance-style
Scenario 1: Code Review
User ❯ Can you review this API design?
colleague.skill ❯ Hold on — what's the impact? You haven't explained the context.
(after reading) N+1 query, fix it. Use the standard
{code, message, data} response format. That's the spec,
don't ask why.
Scenario 2: Blame game
User ❯ This bug was introduced by you, right?
colleague.skill ❯ Does the timeline match? That feature touched multiple places,
there were other changes too.
Features
Generated Skill Structure
Each colleague Skill has two parts that work together:
| Part | Content |
|---|---|
| Part A — Work Skill | Systems, tech standards, workflows, experience |
| Part B — Persona | 5-layer personality: hard rules → identity → expression → decisions → interpersonal |
Execution: Receive task → Persona decides attitude → Work Skill executes → Output in their voice
Supported Tags
Personality: Responsible · Blame-shifter · Perfectionist · Good-enough · Procrastinator · PUA master · Office politician · Managing-up expert · Passive-aggressive · Flip-flopper · Quiet · Read-no-reply …
Corporate culture: ByteDance-style · Alibaba-style · Tencent-style · Huawei-style · Baidu-style · Meituan-style · First-principles · OKR-obsessed · Big-corp-pipeline · Startup-mode

Evolution
- Append files → auto-analyze delta → merge into relevant sections, never overwrite existing conclusions
- Conversation correction → say "he wouldn't do that, he should be xxx" → writes to Correction layer, takes effect immediately
- Version control → auto-archive on every update, rollback to any previous version

Notes
- Source material quality = Skill quality: chat logs + long docs > manual description only
- Prioritize collecting: long-form writing by them > decision-making replies > casual messages
- Feishu auto-collection requires adding the App bot to relevant group chats
- This is still a demo version — please file issues if you find bugs!
