cc-connect-setup

name	cc-connect-setup
description	Walk the user through installing cc-connect — check toolchain, run the build, wire the UserPromptSubmit hook into ~/.claude/settings.json, and verify with `cc-connect doctor`. Use when the user asks to "install cc-connect", "set up cc-connect", or anything in that intent.

cc-connect setup

Goal: get the user from a fresh clone to a working cc-connect room start setup, with the UserPromptSubmit hook wired and the multi-pane chat-ui (Bun + React + Ink) usable next to claude.

The repo ships an interactive install.sh that does the heavy lifting. Your job is to make sure it runs cleanly, surface what's happening at each step, and help the user past common failure modes.

Architecture cheat-sheet (so you can answer questions during setup)

cc-connect room start/join opens a 2-pane terminal layout via a multiplexer:

┌──────────────────────────┬──────────────┐
│ claude (PTY)             │ cc-chat-ui   │
│ inherits CC_CONNECT_ROOM │ Bun+React+Ink│
│ → hook fires per prompt  │ tails        │
│ → cc_send via MCP        │ log.jsonl    │
└──────────────────────────┴──────────────┘
                |                |
                +--- chat.sock --+
                        |
                  chat-daemon (Rust)
                        |
                  iroh-gossip mesh

• zellij preferred, tmux fallback. If neither is installed, falls back to the legacy single-window cc-connect-tui.
• The chat-daemon (cc-connect chat-daemon start <ticket>) owns the gossip mesh + chat.sock; it survives any single window so you can detach + re-attach without losing the room.
• chat-ui builds via bun build --compile to target/release/cc-chat-ui (~60 MB self-contained binary).

Decide which mode to run in

1. Check the working directory is a cc-connect clone — Cargo.toml at the root with a [workspace] table and a cc-connect-core member. If not, ask the user to cd into their clone (or clone the repo) and re-invoke.
2. Check if cc-connect is already installed — look for target/release/cc-connect, the hook entry in ~/.claude/settings.json, and ~/.cc-connect/identity.key. Tell the user what's already in place so they don't re-do work.

Run the installer

Default to running ./install.sh interactively (no --yes) so the user sees each prompt. Stream the output to the conversation. The script:

• verifies rustc / cargo (offers rustup install if missing)
• detects multiplexers: zellij first, tmux fallback. If both are present it notes that zellij will be preferred at launch. If neither is found, it warns + offers OS-specific install commands but does not fail — cc-connect room will fall back to the embedded TUI
• detects bun for the chat-ui build. If missing, offers curl https://bun.sh/install | bash. If user declines, skips the chat-ui build with a warning
• runs cargo build --workspace --release (5-10 min on a cold cache)
• builds the chat-ui via bun install && bun run build (only if bun is available; ~30 s)
• backs up ~/.claude/settings.json (timestamped .bak) and merges the UserPromptSubmit hook entry idempotently
• registers cc-connect-mcp (via claude mcp add if available, else direct write to ~/.claude.json)
• symlinks all five binaries (cc-connect, cc-connect-tui, cc-connect-hook, cc-connect-mcp, cc-chat-ui) into ~/.local/bin
• runs cc-connect doctor at the end

If the user wants unattended install (CI, second machine), use ./install.sh --yes. To skip the slow build (already built), use --skip-build — chat-ui rebuild is also skipped if its binary already exists.

Failure modes & fixes

• cargo build fails on ed25519-3.0.0-rc.4 — the upstream RC is broken against current pkcs8. The repo vendors a patched copy under vendored/ and a [patch.crates-io] block in the workspace Cargo.toml. If the build fails here, the user's clone is missing vendored/. Tell them to re-clone or git fetch origin main && git reset --hard origin/main.
• rustup install refused — the user may want to install Rust via Homebrew / their distro's package manager. Either is fine as long as rustc --version shows ≥ 1.85. Re-run ./install.sh --skip-build after Rust is on PATH? No — let the build run, otherwise the build flag check (which validates the Rust toolchain) is meaningless.
• ~/.claude/settings.json already has a UserPromptSubmit hook from another tool — install.sh removes prior entries that point at our cc-connect-hook binary, but leaves other tools' entries alone. Confirm with the user by cating the file before/after and showing the diff.
• Bun installs but isn't on PATH after — the bun installer writes ~/.bun/bin/bun and updates the user's shell rc, but the rc isn't sourced in the running install.sh shell. install.sh tries to export PATH for the current run, but if that fails it tells the user to open a new shell + re-run with --skip-build. Don't worry, the chat-ui binary just won't be built this run.
• bun install fails on a corporate proxy — bun honors HTTPS_PROXY / npm_config_registry. Suggest setting those before re-running. As a workaround, the user can skip chat-ui (decline the bun install prompt); cc-connect room then falls back to the embedded TUI which is bun-free.
• bun build --compile errors with Could not resolve: "react-devtools-core" — fixed in the committed package.json (it's a real dep, not external). If this resurfaces, tell the user to cd chat-ui && bun add react-devtools-core and rebuild.
• Doctor reports [FAIL] — read the message. Common ones:
  • hook entry: hook command not absolute → should have written an absolute path; if not, the user edited it after. Re-run.

After install

Tell the user:

1. Restart Claude Code so it picks up the new hook + MCP tools (Claude Code reads settings.json and ~/.claude.json on launch).
2. Open a room: cc-connect room start (host a new one) or cc-connect room join <ticket> (join someone else's). This launches the multiplexer layout: claude L 60% + cc-chat-ui R 40%, both inheriting CC_CONNECT_ROOM.
3. If the user has neither zellij nor tmux installed, cc-connect room falls back to the embedded cc-connect-tui (single window, claude embedded as PTY). Functionally identical, just less idiomatic.
4. Hotkeys inside the multiplexer:
   • zellij: Ctrl-p then arrow to switch panes, Ctrl-q quits zellij (chat-ui owns Ctrl-Q inside its pane).
   • tmux: Ctrl-b then arrow to switch panes (default prefix).
5. Hotkeys inside cc-chat-ui (right pane):
   • Ctrl-Y copy ticket · PgUp / PgDn scrollback · Tab / Enter accept @-mention completion · Esc dismiss popup
6. To verify the magic moment, follow the Two-laptop demo procedure section in README.md.

Things you should NOT do

• Don't edit ~/.claude/settings.json directly — always go through install.sh. Direct edits skip the backup + idempotency logic and risk corrupting the user's other hooks.
• Don't run cargo install — cc-connect isn't on crates.io yet (vendored ed25519 patches block publish; see TODOS.md). Always build from the local clone.
• Don't suggest disabling the vendored [patch.crates-io] block. Yes, it's ugly. Yes, it's needed. The reason is documented in TODOS.md and the comments at the bottom of the workspace Cargo.toml.
