CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Commands

The Rust crate lives in src-tauri/. Run Cargo commands from that directory unless a command explicitly targets repository-root assets or scripts.

cd src-tauri

cargo run                                  # Run cc-switch in interactive mode
cargo run -- provider list                 # Run a specific CLI command
cargo run -- --app codex provider list     # Run a command for a specific app
cargo run -- proxy show                    # Inspect proxy state
cargo run -- env tools                     # Check local CLI tools
cargo build --release                      # Build release binary at target/release/cc-switch

cargo fmt                                  # Format Rust code
cargo fmt --check                          # Check formatting, matching CI
cargo clippy                               # Run lints
cargo test                                 # Run all tests
cargo test provider_switch                 # Run tests whose names contain provider_switch
cargo test --test provider_commands        # Run a single integration test target
cargo test --features test-hooks           # Run tests with the test-hooks feature enabled

The repository pins Rust through src-tauri/rust-toolchain.toml to Rust 1.91.1 with rustfmt and clippy. CI currently runs cargo fmt --check for changes under src-tauri/**.

Project overview

CC-Switch CLI is a Rust command-line management tool for Claude Code, Codex, Gemini, OpenCode, Hermes, and OpenClaw. It manages provider configurations, MCP servers, prompts, skills, WebDAV sync, local proxy routes, failover, daemon/start flows, deep-link imports, workspace memory files, and environment checks.

The main crate is src-tauri/; the repository root contains docs, assets, install/update scripts, packaging metadata, and Nix files.

Key Rust entry points:

• src/main.rs parses CLI arguments, initializes logging, creates startup state for most commands, and dispatches to command handlers.
• src/lib.rs declares crate modules and re-exports public types used by integration tests and command code.
• src/cli/mod.rs defines the top-level Clap CLI, global --app flag, and command enum.
• src/cli/commands/ contains direct command implementations for providers, MCP, prompts, skills, config/WebDAV, proxy, failover, Hermes, start, daemon, env, update, completions, and internal commands.
• src/commands/ contains library command helpers that are not top-level Clap subcommands, including OpenClaw workspace file and daily memory operations.
• src/cli/interactive/ and src/cli/tui/ contain the interactive ratatui UI, runtime action handlers, forms, overlays, route state, and UI rendering.
• src/services/ contains durable business logic used by commands and the TUI: providers, auth, MCP, prompts, skills, proxy, WebDAV sync, stream checks, speed tests, environment checks, visible apps, subscription/coding-plan quota checks, and state coordination.
• src/database/ is the SQLite persistence layer. Database owns a mutex-wrapped rusqlite connection, schema creation/migration, backups, and DAO modules for providers, MCP, prompts, skills, settings, proxy state, stream checks, universal providers, and failover queues.
• src/app_config.rs, src/provider.rs, and app-specific config modules (claude_*, codex_config.rs, gemini_*, hermes_config.rs, opencode_config.rs, openclaw_config.rs) define the shared configuration model and live-file adapters for supported apps.
• src/deeplink/ implements the ccswitch://v1/import?... import protocol for provider resources and is exported through lib.rs for tests and callers.
• src/proxy/ implements the local multi-app proxy with Axum handlers, request forwarding, provider routing/failover, provider-specific transformations, response/stream handling, usage logging, model mapping, cache/thinking rectifiers, circuit breaking, and metrics.
• src/daemon/ implements the Unix supervisor daemon, IPC protocol, logging, pidfile, and restart support.
• src/store.rs defines AppState, which ties together the database, an in-memory MultiAppConfig snapshot, startup live-config imports/recovery, and ProxyService.
