Add a WhatsApp adapter backed by Baileys linked-device auth, plus desktop QR binding UI, server config endpoints, sidecar startup wiring, tests, and documentation.
Constraint: Uses WhatsApp Web linked-device auth, not Meta WhatsApp Business Cloud API.
Tested:
- cd adapters && bun run check:adapters
- bun test src/server/__tests__/adapters.test.ts
- cd desktop && bun run check:desktop
- bun run check:native
- bun run check:persistence-upgrade
- bun run check:docs
Not-tested:
- Live WhatsApp QR pairing, because no WhatsApp account/device was exercised here.
- bun run check:server, because the existing src/server/__tests__/conversations.test.ts timeout still fails independently.
Confidence: medium
Scope-risk: moderate
DingTalk uses QR registration to store client credentials, then reuses the existing IM pairing and session bridge. The merged main implementation keeps the existing WeChat QR binding path intact while adding DingTalk as a peer IM platform. The default IM workdir now falls back to the local user working directory so a newly bound chat can start immediately even when recent-project history is empty.
Constraint: Local main already carries WeChat IM, so the merge keeps WeChat config, QR binding, sidecar args, and unbind behavior intact while adding DingTalk.
Rejected: Keep empty defaultProjectDir as project-picker-only | newly bound IM users can hit a dead end with no recent projects.
Confidence: high
Scope-risk: moderate
Directive: Keep IM platform unions synchronized across config, pairing, sidecar args, desktop settings, and docs.
Tested: bun test common/ dingtalk/ wechat/; bun test src/server/__tests__/adapters.test.ts; cd adapters && bunx tsc --noEmit; bun run check:policy; bun run check:server; bun run check:desktop; bun run check:adapters; bun run check:native; bun run check:docs
Not-tested: quality:pr full gate was blocked by existing local main CLI-core diff requiring allow-cli-core-change maintainer approval; live post-fix DingTalk second-message delivery was not repeated after the merge.
WeChat needs a QR-paired path instead of bot-token setup, so the adapter layer now includes the iLink protocol calls, desktop pairing UI, server-side bind/unbind APIs, and shared IM command behavior. Empty project history falls back to the user's default work directory so mobile /new works without pre-opening a desktop project.
Constraint: Tencent iLink login returns a URL that the desktop UI must render as a QR image locally
Constraint: IM adapters should keep /new, /projects, status, permission, and default workdir behavior consistent across WeChat, Feishu, and Telegram
Rejected: Require users to paste absolute project paths for first WeChat sessions | mobile onboarding should work from the default user working directory
Confidence: high
Scope-risk: moderate
Directive: Do not change WeChat polling back to overlapping intervals; getupdates is a long-poll endpoint and must remain serialized
Tested: Real WeChat QR scan, inbound /status, outbound reply, and unbind E2E
Tested: bun run check:adapters
Tested: bun run quality:pr
Not-tested: Re-scan live WeChat after the default-workdir fallback tweak; covered by adapter config tests and PR gate
Three security improvements for adapters.json storage:
- Use crypto.randomBytes for temp filename instead of predictable
Date.now(), preventing TOCTOU symlink race during atomic write.
- Enforce 0o600 permissions on adapters.json via writeFileSync mode
option to prevent credential leakage via permissive umask.
- Enforce 0o700 permissions on ~/.claude/ config directory via
mkdirSync mode option.
adapters.json contains sensitive credentials including Feishu app
secrets and Telegram bot tokens.
- Rate limit: max 5 failed pairing attempts per user per 5 minutes
- Default closed: reject all users when no allowedUsers/pairedUsers configured
- Extract isAllowedUser() to common/pairing.ts to eliminate duplication
