Terminal.app profiles for new Slab machines. Live status colors come from AppDelegate.statusDecor; TerminalReadability checks their contrast after status, pulse, and message tints are combined.

Slab preserves app-supplied colors. Its sixteen ANSI swatches span red, orange, yellow, green, blue, indigo and violet, adjusted to at least 4.5:1 against each status page. Default text targets 7:1, bold ink 4.5:1, and the cursor 3:1. The extended 256-color cube and truecolor remain app-owned: Terminal has no per-character contrast floor for them or faint text. iTerm2 uses its native per-character minimum contrast.

The menubar imports Slab-Rainbow-v2 once and applies colors independently to each tab. It closes only the import's own temporary window; running sessions are preserved. Reinstalling the menubar updates live tabs without reseeding or quitting Terminal.

codex-slab prepares Terminal's page before Codex probes its colors, then records that appearance in the session marker. Status hues continue changing; an existing Codex session keeps its startup light/dark appearance because Codex caches that background. New sessions pick up the current Slab appearance. Older sessions without the marker continue following the appearance setting; resume them through codex-slab if their app colors were chosen for the wrong background. Slab never restarts an active agent to change its colors.

What's here #

terminal-profiles.plist — the Grass base profile plus every Slab-<state>-<dark|light>[-pulse] settings set (the named profiles the Slab menubar switches between per Claude Code session status). Colors + font are captured verbatim.
terminal-profiles.list — plain-text manifest of the profile names in the plist (the installer reads names from here, not by parsing the binary plist).
fonts/ — Monaspace Argon (Regular/Bold/Italic/BoldItalic/Medium/Light), the font the profiles reference. Installed into ~/Library/Fonts.

Install / redeploy on a machine #

slab-seed-terminal            # merge profiles + set Grass as default & startup
slab-seed-terminal --no-default   # profiles only, leave default profile alone
slab-seed-terminal --seed PATH    # use an alternate seed plist

install.sh calls this automatically. Quit Terminal first (the script does this for you) so its in-memory copy doesn't clobber the plist edits on exit; relaunch Terminal afterward.

Re-capture the seed (when you tweak the palette on the reference machine) #

The Slab menubar can create/adjust the Slab-* sets live. Once they look right, re-export them into this seed:

node ../bin/slab-capture-terminal.mjs   # or the python snippet in that file's header

This rewrites terminal-profiles.plist + .list from the current machine's com.apple.Terminal preferences (Grass + all Slab-* sets). Commit the result.
