What Customer Service does

A multi-provider AI customer service agent that automates order lookup, return-eligibility checks, and Stripe refunds with a code-enforced human confirmation gate and inventory restocking. It also exposes the same functionality through a Claude Code plugin using MCP tools and a guided slash command.

README

customer-service

A customer service agent for product returns and Stripe refunds, with a JSON flat-file backing store and a defense-in-depth human-confirmation gate before any refund is issued. Refer to the [architecture](ARCHITECTURE.md) to learn more.

Layout

src/customer-service/ — the standalone Python app: a CLI chat loop backed by a swappable LLM provider (Anthropic, OpenAI, Google, or DeepSeek via NVIDIA). See src/customer-service/README.md (below) for setup.
src/claude-plugin/ — a Claude Code plugin exposing the same tools over MCP, so Claude Code itself can act as the agent. See src/claude-plugin/README.md.

Quick start (CLI)

cd src/customer-service
python3 -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
cp .env.example .env   # fill in an LLM provider API key in .env; leave STRIPE_API_KEY blank for dry-run
customer-service --dry-run

Quick start (Claude Code plugin)

claude --plugin-dir ./src/claude-plugin

Then in-chat: `/customer-service-returns:process-return`.

Safety model

Every refund requires: (1) the model setting `confirmed=true` only after the customer affirms in chat, (2) a from-scratch eligibility re-check inside the refund handler, and (3) an explicit human confirmation step — a terminal prompt in the CLI, or Claude Code's own tool-permission dialog in the plugin. See the implementation plan for full details.

Data

Happy path (ORD-1001): eligibility check → chat confirmation → terminal confirmation → dry-run Stripe refund → inventory incremented 42→43
Outside-window rejection (ORD-1002)
Already-refunded rejection (ORD-1003)
Fail-fast when the provider's API key is missing
