Orchestrator Plugin Quick Reference

Version: 0.1.0 Binary: target/release/nu_plugin_orchestrator (7.6M)

---

Installation

plugin add target/release/nu_plugin_orchestrator
plugin list | where name == nu_plugin_orchestrator

---

Commands

1. Status Check

orch status                              # Default data dir
orch status --data-dir /custom/path      # Custom location
orch status | to json                    # JSON output

Returns: {running, tasks_pending, tasks_running, tasks_completed, last_check, data_dir}

---

2. Workflow Validation

orch validate workflow.k                 # Basic validation
orch validate workflow.k --strict        # Strict mode (checks required fields)

Returns: {valid, errors, warnings}

---

3. Task Queue

orch tasks                               # All tasks
orch tasks --status pending              # Filter by status
orch tasks --limit 10                    # Limit results
orch tasks --status running --limit 5    # Combined filters

Returns: [{id, status, priority, created_at, workflow_id}]

---

Common Patterns

Check if Orchestrator Running

if (orch status | get running) { "✓ Running" } else { "✗ Stopped" }

Validate Before Submit

let valid = (orch validate workflow.k | get valid)
if $valid { "✓ Valid" } else { "✗ Invalid" }

Count Tasks by Status

orch tasks | group-by status | each { |k,v| {status: $k, count: ($v | length)} }

Find High Priority Tasks

orch tasks | where priority > 7 | select id priority

---

Environment

export ORCHESTRATOR_DATA_DIR=/custom/path/to/data

Performance

Operation	Latency	Notes
orch status	~1ms	Single file read
orch tasks	~10ms	1000 tasks
orch validate	~50-100ms	KCL subprocess

5-10x faster than HTTP for read operations
