Source files

Find the plugin root directory. The plugin root directory is most likely in <USER_ROOT>/.claude/plugins/.

Required source files:

<CLAUDE_PLUGIN_ROOT>/scripts/cobrain.py - daemon script to copy
<CLAUDE_PLUGIN_ROOT>/scripts/control.sh - process controller script

Execution principle

Minimize user approval prompts: chain independent shell commands with && into single Bash calls.

Flow

1. Choose output directory

Default: ~/.claude/cobrain
Allow custom absolute path if user asks.
Resolve to absolute path and use it as OUTPUT_DIR.

2. Prerequisite check (one-shot, 1 Bash call)

Run all checks in a single command:

command -v python3 && python3 --version && \
command -v ollama && ollama --version && \
python3 -c "import PIL, ollama; print('ok')" && \
ollama list | grep qwen3-vl

If success: skip installation steps.

If failure: install only missing prerequisites.

Missing Python 3: brew install python
Missing Ollama CLI: brew install ollama
Missing Python packages: pip3 install Pillow ollama
Missing model: ollama pull qwen3-vl:2b

3. Deploy files (1 Bash call)

Chain file operations into one Bash call:

Create OUTPUT_DIR if needed.
Copy daemon script from <CLAUDE_PLUGIN_ROOT>/scripts/cobrain.py to <OUTPUT_DIR>/cobrain.py.
Copy controller script from <CLAUDE_PLUGIN_ROOT>/scripts/control.sh to <OUTPUT_DIR>/control.sh and chmod +x.
Write .source_repo marker to <OUTPUT_DIR>/.source_repo.
Remove stale pid file <OUTPUT_DIR>/cobrain.pid if it exists.

4. Start service (1 Bash call)

Run direct python3 start through the controller:

if [[ -n "${CLAUDE_PLUGIN_ROOT:-}" && -f "${CLAUDE_PLUGIN_ROOT}/scripts/control.sh" ]]; then
  CONTROL_SCRIPT="${CLAUDE_PLUGIN_ROOT}/scripts/control.sh"
elif [[ -f "./plugin/scripts/control.sh" ]]; then
  CONTROL_SCRIPT="./plugin/scripts/control.sh"
else
  CONTROL_SCRIPT="$(ls -dt "$HOME"/.claude/plugins/cache/*/claude-cobrain/*/scripts/control.sh 2>/dev/null | head -1)"
fi
[[ -n "${CONTROL_SCRIPT:-}" && -f "$CONTROL_SCRIPT" ]] || { echo "control.sh not found"; exit 1; }
bash "$CONTROL_SCRIPT" start

5. Completion output

Return:

Done. Daemon is running. Logs:
- <OUTPUT_DIR>/daemon.log
- <OUTPUT_DIR>/runtime.stdout.log
- <OUTPUT_DIR>/runtime.stderr.log
