Symphony Daemon (Portable Pattern)

Use this skill in repos that vendor orchestration/symphony_overlay/daemon/*.

Platform Scope

• This workflow is macOS-only (uses launchd / launchctl).

Variables

Set these at the start of every run:

• REPO_ROOT: absolute path to target repo (defaults to current directory)
• SYMPHONY_ELIXIR_DIR: absolute path to local symphony/elixir
• PLUGIN: plugin id from orchestration/symphony_overlay/daemon/plugins
• PLUGIN_INPUT: plugin input path (absolute, or relative to REPO_ROOT)

export REPO_ROOT="${REPO_ROOT:-$(pwd)}"
export SYMPHONY_ELIXIR_DIR="${SYMPHONY_ELIXIR_DIR:-$HOME/projects_reference/symphony/elixir}"
export PLUGIN="${PLUGIN:-leetcode_hard}"
export PLUGIN_INPUT="${PLUGIN_INPUT:-benchmarks/harness/leetcode_hard_5_alt.json}"

if [[ -f "$PLUGIN_INPUT" ]]; then
  export PLUGIN_INPUT_PATH="$PLUGIN_INPUT"
else
  export PLUGIN_INPUT_PATH="$REPO_ROOT/$PLUGIN_INPUT"
fi

Preconditions

1. python3, jq, launchctl are available.
2. SYMPHONY_ELIXIR_DIR exists.
3. Repo contains orchestration/symphony_overlay/daemon/.
4. Plugin input exists.

Quick validation:

test "$(uname -s)" = "Darwin" || { echo "This skill requires macOS launchd"; exit 1; }
test -d "$SYMPHONY_ELIXIR_DIR" || { echo "Missing SYMPHONY_ELIXIR_DIR"; exit 1; }
test -f "$REPO_ROOT/orchestration/symphony_overlay/daemon/setup_launchd_daemon.py" || { echo "Missing setup script"; exit 1; }
test -f "$PLUGIN_INPUT_PATH" || { echo "Missing plugin input: $PLUGIN_INPUT_PATH"; exit 1; }

Install or Update Daemon

cd "$REPO_ROOT"
SYMPHONY_TASK_PLUGIN="$PLUGIN" \
SYMPHONY_TASK_PLUGIN_INPUT="$PLUGIN_INPUT_PATH" \
SYMPHONY_ELIXIR_DIR="$SYMPHONY_ELIXIR_DIR" \
python3 orchestration/symphony_overlay/daemon/setup_launchd_daemon.py

Enqueue Tasks

cd "$REPO_ROOT"
SYMPHONY_TASK_PLUGIN="$PLUGIN" \
SYMPHONY_TASK_PLUGIN_INPUT="$PLUGIN_INPUT_PATH" \
"$REPO_ROOT/orchestration/symphony_overlay/daemon/enqueue_plugin_tasks.sh"

Switch Plugin/Input Without Reinstall

cd "$REPO_ROOT"
SYMPHONY_TASK_PLUGIN="swe_bench_verified" \
SYMPHONY_TASK_PLUGIN_INPUT="$REPO_ROOT/benchmarks/harness/swe_bench_verified_5.json" \
"$REPO_ROOT/orchestration/symphony_overlay/daemon/enqueue_plugin_tasks.sh"

Troubleshooting

• Daemon not receiving tasks:
  • rerun setup_launchd_daemon.py
  • check metadata exists and has expected values:

cat "$HOME/Library/Application Support/orchestrator_benchmark/symphony_daemon/daemon_metadata.json"

• Plugin import errors:
  • confirm plugin exists under daemon/plugins
  • run plugin tests:

cd "$REPO_ROOT"
python3 -m pytest -q orchestration/symphony_overlay/daemon/tests/test_plugins.py

Fairness and Isolation (Benchmark Use)

1. Use per-orchestrator /tmp directories.
2. Use unique port ranges per orchestrator.
3. Keep task specs/acceptance criteria identical across orchestrators.
4. End each attempt with either benchmark_commit or machine-readable blocked_reason.
