Agent skill
tmux-status-debug
Debug and test tmux pane status detection for AI agents (opencode, claude, amp). Use when patterns aren't matching, status icons are wrong, or adding new detection patterns.

Debugging tmux-opencode-integrated Status Detection
When to Use
- Status icons showing wrong state (e.g., showing ERROR when agent is IDLE)
- Adding new patterns for agent detection
- Testing pattern matching against real pane content
Quick Commands
List all agent panes
bash
tmux list-panes -a -F "#{session_name}:#{window_name}.#{pane_index} #{pane_current_command}" | grep -E "opencode|claude|amp"
Capture pane content (raw)
bash
tmux capture-pane -t "main:1" -p -S -30 | tail -40
Capture with control chars visible
bash
tmux capture-pane -t "main:1" -p -S -30 | cat -v | tail -40
Check if pattern exists in pane
bash
tmux capture-pane -t "main:1" -p -S -20 | grep -o "pattern"
Debug Script
Create /tmp/debug_status.py and run with the Nix Python that has libtmux:
python
import sys
sys.path.insert(0, "/Users/emiller/.config/dotfiles/packages/tmux-opencode-integrated/scripts")
import smart_name
import re
import libtmux
server = libtmux.Server()
for session in server.sessions:
for window in session.windows:
for pane in window.panes:
program = smart_name.get_pane_program(pane)
if program in smart_name.AGENT_PROGRAMS:
print(f"\n=== {program} in {session.name}:{window.name} ===")
try:
cmd_output = pane.cmd("capture-pane", "-p", "-S", "-20").stdout
if isinstance(cmd_output, list):
content = "\n".join(cmd_output)
else:
content = str(cmd_output)
cleaned = smart_name.strip_ansi_and_control(content)
print(f"Last 300 chars (cleaned):\n{cleaned[-300:]}")
print(f"\n--- Status: {smart_name.get_opencode_status(pane)} ---")
except Exception as e:
print(f"Error: {e}")
Find the Nix Python with libtmux
bash
# Build the package and get the store path
nix build .#tmux-opencode-integrated --no-link --print-out-paths
# Check wrapper to find Python path
head -10 /nix/store/<hash>-tmux-opencode-integrated-*/share/tmux-plugins/tmux-opencode-integrated/scripts/smart-name.sh
# Run debug script with that Python
/nix/store/<python-hash>-python3-*-env/bin/python3 /tmp/debug_status.py
Pattern Testing
Test patterns against sample content:
python
import re
content = """ctrl+t variants tab agents ctrl+p commands • OpenCode 1.1.30"""
patterns = [
(r"OpenCode \d+\.\d+\.\d+", "IDLE - version"),
(r"ctrl\+p commands", "IDLE - status bar"),
(r"esc interrupt", "BUSY - can interrupt"),
(r"Esc to cancel", "BUSY - can cancel"),
(r"■■■", "BUSY - progress bar"),
]
for pattern, desc in patterns:
if re.search(pattern, content, re.IGNORECASE):
print(f"✓ {desc}: {pattern}")
Status Priority
Order matters - first match wins:
- ERROR - Traceback, panic, FATAL ERROR, API errors
- WAITING - Allow once?, Permission required, yes/no/skip prompts
- BUSY - Thinking..., spinners, Running tools, esc interrupt
- IDLE - Input prompt, context display, OpenCode version, ctrl+p commands
- UNKNOWN - No patterns matched (fallback)
Adding New Patterns
- Capture real pane content with the debug script above
- Identify unique text that indicates the state
- Add pattern to appropriate list in
smart_name.py - Add test case in
tests/test_smart_name.py - Run tests:
uvx pytest tests/test_smart_name.py -v - Rebuild:
nix build .#tmux-opencode-integrated
Common Issues
"No module named 'libtmux'"
Using wrong Python. Must use the Nix-wrapped Python from the package.
Patterns not matching
Terminal control characters may be interfering. The strip_ansi_and_control() function should handle this, but check with cat -v to see raw content.
Status showing ERROR when it shouldn't
Check if content contains error-like strings from previous output. The detection looks at last 20 lines of pane content.
