tetherly 0.1.0

Discord to tmux session bridge for agent-driven workflows.

tetherly

Discord channel ↔ tmux session bridge.

📖 Documentation is in docs/ — split into user docs (setup, commands, troubleshooting) and contributing docs (internals). This README is a quick start.

Features

• /bind session:<name>: bind the current Discord channel to a tmux session
• /config auto_send:<true|false>: enable or disable plain-text auto-send for the current bound channel
• /send text:<message>: send text plus Enter into the bound tmux session
• /key key:<Enter|Escape|Ctrl-C|Ctrl-D|Tab|Up|Down|Left|Right>: send a special key into the bound tmux session
• /tail lines:<n>: fetch recent tmux output
• /status: inspect the current binding and tmux session status
• tetherly discord-send --message <text>: let an agent inside a bound tmux session send a reply back to Discord
• tetherly codex-stop / tetherly codex-permission-request: Codex hook handlers that forward messages to the bound Discord channel

Requirements

• Python 3.11+
• tmux installed
• A Discord bot token (Message Content Intent enabled if you want plain-text auto-send)

Setup

Install once on your machine:

pipx install tetherly
tetherly init

tetherly init is interactive. It writes ~/.tetherly/.env and asks where to install Codex hooks:

• Global — writes ~/.codex/hooks.json once. Hooks fire in every project automatically; nothing per-project.
• Project — skip global hooks and run tetherly install-hooks inside each project where you want them.
• Skip — don't touch Codex hooks.

Then start the bot:

tetherly

That's it. State lives at ~/.tetherly/state.json so a single bot can serve every project.

Per-project usage

For each project you want to drive from Discord:

tmux new -s <session-name>
# inside the bound channel on Discord:
#   /bind session:<session-name>
#   /config auto_send:true

If you chose Project mode during init, also run once per project:

cd <project>
tetherly install-hooks

install-hooks accepts --global to (re)install user-level hooks instead.

Sending from inside a session

tetherly discord-send --message "작업 끝났습니다"
cat result.txt | tetherly discord-send --stdin
tetherly discord-send --session t1 --message "..."   # explicit session

Configuration

tetherly init writes everything you need. Advanced overrides live in ~/.tetherly/.env or shell env:

Variable	Default	Notes
DISCORD_BOT_TOKEN	(required)	Bot token
TETHERLY_ALLOWED_USER_IDS	(required)	Comma-separated user IDs
TETHERLY_ALLOWED_GUILD_IDS	—	Restrict commands to these guilds
TETHERLY_ALLOWED_ROLE_IDS	—	Allow members holding any of these roles
TETHERLY_TEST_GUILD_ID	—	Dev guild for instant slash-command sync
TETHERLY_STATE_PATH	~/.tetherly/state.json	Where bindings are persisted
TETHERLY_DEFAULT_TAIL_LINES	40	Default /tail line count
TETHERLY_MAX_TAIL_LINES	200	Cap for /tail
TETHERLY_LOG_LEVEL	INFO	Logger verbosity

A .env in the current working directory still overrides ~/.tetherly/.env.

Codex hooks

Both hooks only fire when the active tmux session has TETHERLY_NOTIFY_ON_FINISH=1 — /bind sets that flag automatically, so projects without a binding stay silent even when global hooks are installed.

• Stop → tetherly codex-stop forwards last_assistant_message to the bound channel.
• PermissionRequest → tetherly codex-permission-request forwards the tool/command/reason. It does not return an allow/deny decision, so Codex's normal approval prompt still appears.
