# ║  This overlay adds agent-aware pane styling and team keybindings to        ║
# ║  your existing tmux config. It is sourced automatically by tmux.conf       ║
# ║  but can also be used independently:                                       ║
# ║                                                                            ║

# ║  What this overlay does:                                                   ║
# ║    - Shows agent names in pane borders (pane_title)                        ║
# ║    - Enables aggressive resize for better multi-agent layouts              ║
# ║    - Adds safety bindings to prevent accidentally killing agent panes      ║
# ║    - Provides team-specific keybindings for navigation and management      ║
# ║    - Fixes known Claude Code + tmux compatibility issues                   ║
# ║                                                                            ║
# ║  Convention: Each Claude agent pane should set its title on startup via:   ║
# ║    printf '\033]2;agent-name\033\\'                                        ║
# ║  The shipwright CLI does this automatically when spawning agent panes.     ║

# Format: pane index, agent name, running command, zoom indicator
# Active pane: bold + bright │ Inactive: muted, recessed
# Uses #{pane_title} which each agent sets via OSC 2 escape sequence

# This prevents smaller terminal clients from constraining team pane sizes

# DARK THEME — Active pane gets a subtle background lift
# ═══════════════════════════════════════════════════════════════════════════
# Inactive panes: deep navy, dimmed text — recedes visually
# Active pane: subtle bg lift, softer warm gray text — easy on the eyes
# NOTE: Claude Code renders its own colors for TUI elements. These fg values
# only affect plain terminal output (shell prompts, command output, etc.)
# The bg lift (#1a1a2e → #1e1e36) gives the active pane a "floating" feel.

# ROLE-COLORED BORDERS — Active pane border reflects agent role
# ═══════════════════════════════════════════════════════════════════════════
# When you switch panes, a hook reads the pane title and sets the active
# border color to match the agent's role:
#   leader/pm    → cyan (#00d4ff)      builder/dev   → blue (#0066ff)
#   reviewer     → orange (#f97316)    tester        → yellow (#facc15)
#   security     → red (#ef4444)       docs          → violet (#a78bfa)
#   optimizer    → green (#4ade80)     researcher    → purple (#7c3aed)
#
# The hook script must exist; -q makes source-file silent if missing.
# Falls back to cyan for non-agent panes (plain shell, vim, etc.)
