Zellij Skill

Configuration Locations

  • Layout files: home/.config/zellij/layouts/
  • Plugin file: home/.config/zellij/plugins/zjstatus.wasm
  • Always edit files in the dotfiles repo, not symlinked files in ~/.config/

Powerline Characters

Claude Code strips unicode characters. Use placeholders in the layout file (layout.kdl in this skill folder):

  • {{PL_RIGHT}} - right-pointing arrow (U+E0B0)
  • {{PL_LEFT}} - left-pointing arrow (U+E0B2)

After editing the layout, run the converter:

.claude/skills/zellij/convert-layout

This reads layout.kdl from the skill folder, replaces placeholders with actual powerline chars, and writes to ~/.config/zellij/layouts/layout.kdl.

VHS Testing

CRITICAL: NEVER run zellij commands in the user's active session. VHS creates its own isolated terminal.

CRITICAL: ALWAYS use the tapes in this skill folder. NEVER create ad-hoc tape files with different output names.

Use VHS to verify visual changes:

  1. Delete any existing test session: zellij delete-session zellij-test
  2. Run the appropriate tape from .claude/skills/zellij/:
    • layout.tape - Tests tabs and zjstatus bar appearance
    • swap-layout.tape - Tests swap layouts with multiple panes (creates 3 panes, cycles through layouts)
  3. Output screenshot ALWAYS goes to tmp/zellij.png (same name, no versioning)
  4. Read the screenshot to verify before telling user the fix is complete
  5. Clean up the test session: zellij delete-session zellij-test

The tapes create a dedicated zellij-test session. Never use zellij action commands directly - they affect the user's current session.

Color Scheme

Use Catppuccin Mocha colors. Reference by name in requirements:

  • base, surface1, lavender, text (not hex codes)

Top Bar Layout

  • Session name, tabs with powerline arrows, hostname/username
  • Arrows between tabs use base color as foreground
  • Active tab: accent background, base text color
  • Inactive tabs: surface background, text color

Bottom Bar Layout

  • Mode indicator, active tab name only, datetime
  • Show only active tab name (no inactive tabs)

Verification Checklist

Before declaring complete, verify:

  • Top bar arrows use dark/base color between all tabs
  • No accent color triangles between inactive tabs
  • Bottom bar shows only active tab name
  • Bottom bar has no powerline triangles
  • Session name arrow transitions correctly to first tab
