Slack in your terminal, as yourself: a full TUI plus scriptable commands. One Rust binary called slack, ~10 ms startup.

cargo install --git https://github.com/vmeyet/slack-tui

That is all: the slack command is now on your path.

Optional shell completions: slack completions zsh > ~/.zfunc/_slack (also bash, fish). Update with slack update (a no-op when you already run the latest commit, -f to rebuild anyway); remove with cargo uninstall slack. slack --version prints the version and the commit it was built from.

slack login acme    # opens acme.slack.com in your browser; log in there, done
slack whoami
slack logout        # forgets the keychain entry, config and cache

slack        # or slack tui

Three panes: channels, messages, thread. Messages, edits, deletions and reactions arrive live; other channels light up with ●. Whoever is typing in the open conversation shows under the last message.

⌘k also works on terminals that forward it (Ghostty, Kitty, WezTerm, iTerm2 with the kitty keyboard protocol).

Command line. :join #ops, :leave, :go @bob, :msg @bob on my way, :compose, :react rocket, :search deploy failed, :export md, :read, :snooze 1h, :set theme=nord, :help, :quit. Tab completes verbs, channels, people and emoji; ↑ recalls history.

Inbox. Unread DMs, mentions and thread replies in one list. → marks read, ← snoozes (1h, 3h, tomorrow, monday), r replies in place, enter opens the conversation, a clears everything.

Triage (opt-in). With [typesafe] enabled = true, TypeSafe's Jev model ranks the inbox (↩ needs reply first, then ‼ urgent and ! soon) and tags each firehose line as incident, question-for-me, fyi or noise. The firehose hides noise (n shows it) and paints incidents red. Lines show at once; the tag lands when Jev answers. slack promises (or p) asks Jev which of your own messages promised a follow-up, and whether a later reply of yours in the same thread closed it. If Jev cannot answer, you get one ⚠ typesafe unavailable notice and the plain views.

No live feed? If the workspace refuses the RTM websocket, the open conversation is polled every 10 seconds (↻ in the status bar).

Every command takes --json (for scripts and agents) and -w <workspace>.

Messages are markdown by default and are sent as Block Kit rich_text: **bold**, _italic_, ~~strike~~, `code`, fenced code, # heading, lists, > quotes, ---, [label](url), @user, #channel, :emoji:. Use --raw to send Slack mrkdwn untouched.

~/.config/slack-tui/config.toml, every key optional:

[tui]
theme = "catppuccin"    # dracula, catppuccin, catppuccin-latte, rosepine, rosepine-dawn, nord, tokyonight, monokai
highlight = "#2a2a2a"   # fill under the selected row; by default only the ▎ bar marks it
images = true           # inline thumbnails on Kitty, Ghostty, WezTerm and iTerm2

[links]
show_url = false        # true prints `label (url)`; false keeps a clickable label

[firehose]
highlight = ["prod", "error|failed", "@bob"]   # case-insensitive regexes

[typesafe]
enabled = false         # true sends unread, live and your own message text to api.typesafe.ai to rank, tag and find promises

The TypeSafe key comes from TYPESAFE_API_KEY, else the keychain service typesafe. TYPESAFE_DISABLED=1 or ~/.agents/typesafe/disabled turns it off without touching the config.

:set theme=…, :set highlight=… and :set images=on|off write this file from the TUI.

1. slack login starts a throwaway browser profile and drives it over the DevTools protocol.
2. Once you are logged in, it reads the web client's session: the xoxc token and the d cookie.
3. It stores both in the macOS login keychain (service slack-tui), closes the browser and deletes the profile.

The session never touches disk unencrypted. It acts as you, with everything you can do in Slack: treat it like a password. The keychain is accessed through /usr/bin/security, so rebuilding the binary never triggers an "allow access" prompt.

Unread badges, the inbox and sidebar sections use undocumented web-client endpoints (client.counts, subscriptions.thread.*, users.channelSections.list). Slack can change them without notice.

cargo test                       # unit + end-to-end against a mock Slack API
cargo test -- --ignored          # also the real keychain round trip
SLACK_TUI_DEBUG=1 slack login …  # trace the browser capture

The app was called slack-cli before. Its old folders and keychain entries move to slack-tui the first time they are used, and SLACK_CLI_* variables still work.
