v0.10.1

Bug Fixes

• Pane naming in detached sessions: Fixed create_named_pane not properly naming panes when running in detached sessions. Added delay and verification after pane creation, with retry logic to find and rename the correct pane.

• Claude pane protection: Added safeguards to prevent accidentally closing the Claude pane:

  • destroy_named_pane blocks closing any pane with "claude" in the name
  • close_pane checks the focused pane before closing

Documentation

• Added BUG-pane-naming.md documenting the root cause and fix

v0.10.0 - Spatial Layout Visualization

What's New

session_map Visual Layout

The session_map tool now shows the actual spatial arrangement of panes within each tab:

╔══════════════════════════════════════════════════════════════╗
║ ● fascinating-quasar                                         ║
╚══════════════════════════════════════════════════════════════╝
    [Tab #1] idle
  ┌────────────────────────────┐┌─────────────┐┌─────────────┐
  │                            ││    shell    ││             │
  │          claude            │├─────────────┤│    shell    │
  │                            ││    shell    ││             │
  └────────────────────────────┘└─────────────┘└─────────────┘

• Shows side-by-side splits, stacked panes, and nested layouts
• Focused panes highlighted in orange
• Proportional sizing based on actual layout percentages
• Properly skips UI chrome (tab-bar, status-bar plugins)

Bug Fixes

• Fixed layout parser to handle nested pane structures
• Fixed plugin pane filtering (no more phantom shells)
• Improved T-junction rendering for overlapping borders

v0.6.0 - Autonomous Workflow Tools

Major Update: Autonomous Workflow Tools for Bioinformatics

This release adds 20+ new tools enabling fully autonomous workflow execution through OpenCode or Claude Code.

New Features

Core I/O with Pane Targeting

• write_to_pane - Send text to any pane by name
• send_keys - Ctrl+C, arrows, function keys
• search_pane - Regex search in pane content

Output Monitoring

• wait_for_output - Block until pattern appears
• wait_for_idle - Wait for output to stabilize
• tail_pane - Incremental output reading

Compound Operations

• run_in_pane - Execute command with wait and capture
• create_named_pane - Idempotent pane creation with registry
• destroy_named_pane - Cleanup named panes

REPL Interaction

• repl_execute - Run code in IPython/R/Julia, capture output
• repl_interrupt - Send Ctrl+C with prompt detection

SSH/HPC Integration

• ssh_connect - Open SSH sessions in named panes
• ssh_run - Execute remote commands
• job_submit - Submit SLURM/PBS jobs with tracking
• job_status - Check job state

Infrastructure

• SessionState class for persistent pane/SSH/job registry
• with_pane_focus helper for transparent pane targeting
• strip_ansi utility for clean LLM output
• Enhanced layout parser with full metadata

Breaking Changes

• Removed write_bytes (use send_keys)
• Removed run_command (use run_in_pane)
• Removed dump_screen (use read_pane)

v0.3.0

What's New

Safety Guidelines for Running Inside Zellij

Added comprehensive documentation for safely using zellij-mcp when Claude Code runs inside a Zellij pane:

• Always specify your session - Use session_info to discover session name, then pass --session on all commands
• Never close your own pane - Safe patterns for creating and cleaning up work tabs
• Capture output correctly - Switch tabs before dumping screen content
• Recommended workflow - Step-by-step pattern for running commands in separate tabs
