cc-session-control

tmux-first workbench (TUI + headless CLI) for the agent CLIs on one machine — Claude Code, Codex CLI, and Kimi Code: sessions across all three, plus Claude Code background agents and Remote Control.

CLI command: csctl

Features

• Sessions Tab — One machine-wide list of Claude Code, Codex, and Kimi Code sessions (CLI column: cc/cx/km), discovered from each CLI's own on-disk state — not just sessions csctl started. Resume tmux-first (Enter resumes into a project-labelled window in the shared csctl tmux session via each CLI's native resume command; t bare-terminal fallback; R backgrounds into tmux; f forks where the CLI supports it; ⧉ marks tmux-resident sessions), terminate, and delete; a cleanup submenu (c) prunes empty/short Claude sessions and sweeps orphan artifact directories, zombie session files, and aged global entries (cleanup models Claude state only)
• Projects Tab — The startup tab / launcher: Enter opens a CLI chooser (active providers only, claude focused first — so Enter-Enter starts claude) to open a new project-labelled window in the shared csctl tmux session; x/k jump straight to codex/kimi; start/stop Claude RC servers per project (o/s), toggle per-project auto Remote Control (c), show running/stopped/dead states
• Background agents Tab — List Claude Code background agent jobs; take over, respawn, watch their timeline, stop, or remove them

Non-Claude liveness is deliberately conservative (ADR-0005). A real resume target in argv (codex resume <sid-or-unique-name> / kimi --session <sid>) has priority; csctl's own identity-checked tmux dispatch metadata is a supplement for dispatched windows, and is essential after Kimi rewrites its argv at runtime. A brand-new session started from the launcher (the Enter chooser or x/k) has no sid yet, so it stays unbound, as does any other bare-launched TUI; unbound processes are never stop/takeover targets.

All agent sessions csctl dispatches — new, resumed, forked, backgrounded, or background-agent respawns — share the tmux session named csctl; their window names retain the project. Existing live sessions in older or user-created tmux sessions are entered in place and are never migrated automatically. Managed Remote Control servers remain isolated in the configurable rc session.

Built with urwid.

UI language: Simplified Chinese (notifications and status text). CLI output is in English.

Requirements

• Python 3.12+
• At least one supported agent CLI installed and authenticated: Claude Code, Codex CLI, and/or Kimi Code — each is discovered automatically when its state home exists (~/.claude, ~/.codex, ~/.kimi-code; official relocation variables CODEX_HOME / KIMI_CODE_HOME are honored)
• tmux (the primary session-lifecycle carrier: launch, resume, background, and survive terminal/SSH disconnects; managed Remote Control servers also use it)
• Linux / WSL. Other POSIX systems are not supported; without /proc, csctl shows degraded state and refuses destructive actions whose safety it cannot prove.

Installation

Install the latest published release:

uv tool install cc-session-control
# or
pipx install cc-session-control

Upgrade later with uv tool upgrade cc-session-control (or pipx upgrade cc-session-control).

Latest master build

To try the newest master before it is released, install from GitHub:

uv tool install --reinstall git+https://github.com/dzshzx/cc-session-control.git

csctl manages local state on the machine where it is installed: the active providers' ~/.claude, ~/.codex, and ~/.kimi-code homes, local tmux, and the project launcher entries recorded in ~/.claude.json. Install it separately on each machine whose sessions you want to manage. For working on the code instead of using it, see CONTRIBUTING.md.

Usage

The TUI is the primary surface — Remote Control management and session cleanup live there (Projects tab and the Sessions cleanup submenu). The headless CLI keeps only the agent-facing commands: resume and agents.

# Open TUI
csctl

# Resume rescue (headless): list sessions of ALL providers across
# directories with ready-to-copy resume commands (native /resume only
# searches the cwd and hides sdk-ts/bridge sessions); non-Claude rows
# are tagged [codex]/[kimi]
csctl resume                 # Page 1, 20 per page
csctl resume mybug           # Keyword: sid/cwd/title, then transcript body
csctl resume --page 2        # Next page
csctl resume --all           # Everything, no paging

# Read-only inventory
csctl agents                 # Background agents: state, tempo, name, cwd

# Options
csctl --theme light            # Force the TUI palette (auto/dark/light)
csctl --version

The companion Claude Code skill (claude-session-doctor) is distributed via the skills CLI — install it with skills add dzshzx/agent-skills --skill=claude-session-doctor (it is no longer bundled with this package).
