slab-deck

A control center for Claude Code in the SLAB design language: dark surfaces, hue only on glyphs and outcome markers (› ▸ ✓ ✗ ! · ↳ ▪), no box drawing. Two parts that work together:

• statusline-slab.sh fills Claude Code's own status line slot with gauges in true colour.
• mod/slab-deck is a mod on the function-hooks plugin API (Claude Code 2.1.289+): a live band above the prompt, a docked deck pane, popups and tmux navigation.

What it shows

Statusline (Claude Code's status line slot): model, repo and branch, effort | context, 5h and 7d rate-limit gauges (amber from 70 %, red from 90 %, reset countdown once a window passes 70 %), prompt-cache hit rate, output-per-turn sparkline (handed over by the mod), session clock, lines +N −N. Facts drop by priority when the terminal narrows; a window at 70 % or more outlasts the repo name.

Band above the prompt: while a turn runs, the animated ▪▪▪ working indicator with elapsed time, step, tokens, tok/s and the tools running; when idle, your tmux windows as links (1–9) and actions (d deck, n window, s split, h keys).

Deck pane — /deck [section]

| section | contents | | --- | --- | | overview | session facts, context, rate limits and resets, output per turn, recent tool calls | | context | the /context grid, categories, autocompact mark, memory files | | tools | calls by tool, 30-minute timeline, recent calls | | agents | subagents and their status | | git | changed files with diff bars, commits, history graph in a new tmux window | | tmux | all panes of the session: live peek, window minimap, go there, new window, split, zoom | | usage | rate limits, token totals, cache hit, turn durations |

Popups for a tool call, a turn, a tmux pane and the key list (esc closes).

Animations: the ▪▪▪ indicator breathes while a turn runs; the deck's context and rate-limit gauges sweep up when it opens and glide to each new value. Both repaint cells in place ($.ui.blit), no redraw. P1_REDUCED_MOTION=1 or SLAB_REDUCED_MOTION=1 freezes them.

Also /deck-band full|compact|off and toasts when context or a rate limit crosses 80 %. The tmux actions only select, open or split; nothing closes, kills or types into another pane.

Install

git clone https://github.com/5omeOtherGuy/slab-deck
claude --plugin-dir slab-deck/mod/slab-deck

For every session, in ~/.claude/settings.json:

"env": { "CLAUDE_CODE_PLUGIN_DIRS": "/path/to/slab-deck/mod/slab-deck" },
"statusLine": { "type": "command", "command": "/path/to/slab-deck/statusline-slab.sh", "padding": 0, "refreshInterval": 2 }

The statusline needs jq and git, and works without the mod (no sparkline then). refreshInterval re-fits it after a resize and keeps its clock and countdowns current; one run takes about 60 ms.

tmux and git features turn on by themselves when Claude Code runs inside tmux or a git repository. P1_REDUCED_MOTION=1 or SLAB_REDUCED_MOTION=1 freezes the working indicator.
