+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+PicoClaw is an ultra-lightweight personal AI assistant written in Go, designed to run on minimal hardware (<10MB RAM). It supports multiple LLM providers and chat channels (Telegram, Discord, QQ, WhatsApp, Feishu, Slack, Matrix, etc.).
+
+This repo is a **company internal fork**. The `main` branch mirrors upstream; all development happens on `internal_main`. Branch off `internal_main` for features/bugfixes, never develop directly on `main`.
+
+## Build & Development Commands
+
+```bash
+# Build
+make build                  # Build for current platform (runs go generate first)
+make generate               # Run go generate only
+make build-launcher         # Build web console (frontend + Go backend)
+
+# Test
+make test                   # All Go tests
+go test ./pkg/agent/        # Test a specific package
+go test -run TestName -v ./pkg/session/  # Run a single test
+
+# Lint & Format
+make lint                   # golangci-lint (strict config in .golangci.yaml)
+make fmt                    # Format code (gci, gofmt, gofumpt, goimports, golines)
+make vet                    # Static analysis
+make check                  # Full pre-commit: deps + fmt + vet + test
+
+# Frontend (web/frontend/)
+cd web/frontend && pnpm install
+pnpm dev                    # Vite dev server
+pnpm build                  # Production build
+pnpm build:backend          # Build into web/backend/dist for embedding
+pnpm lint                   # ESLint
+pnpm check                  # Prettier + ESLint fix
+
+# Web console dev (web/)
+cd web && make dev           # Start backend + frontend dev servers
+```
+
+## Go Build Configuration
+
+- `CGO_ENABLED=0` — static binaries, no cgo
+- Build tags: `stdjson` (standard library JSON)
+- WhatsApp native support: build tag `whatsapp_native` (separate, larger binary)
+- LDFLAGS inject version from git tags
+- Module: `github.com/sipeed/picoclaw`, Go 1.25+
+
+## Architecture
+
+### Core Flow
+```
+Channel → MessageBus → Agent → LLM Provider
+                         ↕
+                     Tool System (exec, fs, web, MCP, cron, skills)
+```
+
+### Key Packages (pkg/)
+- **agent/** — Agent loop, registry, memory, thinking. Multi-agent with per-agent workspace/model/tools
+- **bus/** — Central MessageBus for decoupled channel↔agent communication
+- **channels/** — Pluggable channel implementations (telegram, discord, qq, whatsapp_native, feishu, dingtalk, slack, matrix, irc, line, wechat_work, onebot, maixcam)
+- **providers/** — LLM provider abstraction with fallback chains (Anthropic, OpenAI, OpenRouter, Gemini, Groq, Zhipu, etc.)
+- **tools/** — Extensible tool registry with safety features (deny patterns, path restrictions)
+- **mcp/** — Model Context Protocol integration (Go SDK, HTTP+stdio transport, BM25 tool search)
+- **session/** — JSONL-based session persistence
+- **skills/** — Installable skill packages with ClawHub registry
+- **config/** — Configuration loading/validation
+- **commands/** — Command registry and execution
+
+### CLI Structure (cmd/picoclaw/)
+Entry point is `cmd/picoclaw/main.go` using cobra. Subcommands in `cmd/picoclaw/internal/` (agent, gateway, auth, cron, migrate, onboard, skills, status, version).
+
+### Frontend (web/frontend/)
+React 19 + TypeScript + Vite + TailwindCSS 4 + TanStack Router + Radix UI + Jotai state + i18next. Built output embeds into the Go binary at `web/backend/dist/`.
+
+## Code Style
+
+- Formatting enforced by golangci-lint: gci (import ordering: std → third-party → local), gofumpt, golines (120 char max)
+- Use `any` instead of `interface{}`
+- Commit messages: conventional commits, imperative mood, English ("Add retry logic" not "Added retry logic")
+- Reference issues in commits: `Fix session leak (#123)`
+
+## Branching (Internal Fork)
+
+```
+upstream/main → main (mirror only) → internal_main (dev mainline) → feature/*, bugfix/*
+```
+
+PRs target `internal_main`. To contribute upstream: cherry-pick from `main` branch.
