## Core capabilities
- **WeChat omnichannel access** — Unified access for Official/Service Accounts and Mini Programs; normalizes text/image/voice/file, turns events into greetings, with fallback for unknown types.
- **Knowledge-grounded reply** — The digital employee answers from the enterprise knowledge base with citations; when there is no match it says so instead of inventing, honoring the citation rule.
- **Session & tenant management** — Multi-tenant isolation; one tenant can bind many WeChat entries. Sessions are serialized per user with double-track idempotent de-duplication.
- **Sub-second gateway + async** — The callback returns success first, then does business — never blocking on the model. End-to-end timeouts fall back to a holding message with a Run-ID for resumption.
- **Quota & activation billing** — Counts by window and message type, degrades beyond the window without silent failure; issued/renewed via activation codes, downgrade on expiry and restore on renewal.
- **Self-serve onboarding** — A console and wizard: fill credentials, configure the employee, IP-allowlist guidance and error-code hints — then go live gradually and watch usage.

## Highlights
### WeChat-channel rules, without losing LLM experience
An inbound/outbound gateway designed for WeChat's hard constraints: ack-then-async, byte-safe splitting and double-track quota counting turn a flaky third-party channel into a reliable service entry.

### The service brain plugs straight into ThinkDE
ThinkCS builds no dialog or knowledge engine; it orchestrates conversations through ThinkDE digital-employee open APIs, reusing mature agent capabilities for customer service while focusing on channel, tenant and billing.

## Use cases
Service-account support · Mini-program chat · Official-account messages · Pre-sales Q&A · After-sales tickets
