> colin: a coding-agent box on tenki.cloud, one command away, with auto-resume.

colin is a single bash script. It creates or resumes a tenki.cloud sandbox named
colincode-<harness>, provisions tmux, starts the chosen coding agent inside tmux,
and attaches you to it. Supported harnesses: claude (Claude Code, with Remote
Control so the box is reachable from claude.ai/code), opencode, and codex.

## Install

    curl -fsSL https://colincode.org/install.sh | sh

Requires the tenki CLI (https://tenki.cloud) and jq. The raw script is served at
https://colincode.org/colin.

## Commands

    colin                      pick an agent from a menu, then up
    colin <harness> [action]   harness: claude | opencode | codex
    colin <action>             default harness (claude, or $COLINCODE_HARNESS)

    up (default)   create or resume the box, start the agent, attach to it
    ssh            same as up (attach to the running agent's tmux session)
    shell          plain shell in the box
    run -- <p>     one-shot headless prompt
    status         show box state
    down           pause the box (auto-resumed on next command)
    rm             terminate the box
    colin auth [h] sign in; for claude this runs `claude auth login` inside the
                   box (Remote Control needs a full login, not a setup-token)
    colin ls       list every colincode box

COLINCODE_HARNESS (claude), COLINCODE_CPU (4), COLINCODE_MEMORY_MB (8192),
