PowerShell Orchestration State Machine

Canonical checkpoint and resume behavior for orchestration agents running multi-step PowerShell delivery flows.

When to Use This Skill

Use this skill when:

• A workflow spans multiple delegations and commands.
• Execution may be interrupted and must resume deterministically.
• An orchestrator must avoid repeating completed steps.

Canonical Checkpoint Location

• artifacts/orchestration/powershell-orchestrator-state.json

Required Checkpoint Fields

• objective
• change_budget_estimate
• path_selected (small or large)
• promotion-type
• short-name
• relativeFile
• long-name
• issue-num
• feature-folder
• work-mode (minor-audit, full-feature, or full-bug; normalize legacy full to full-feature before persistence)
• plan-path (minimal or full plan path)
• completed_steps
• next_step
• last_updated

For short-path runs, also persist:

• small_path_qc_summary
• small_path_audit_artifacts
• bootstrap_mode (manual-bootstrap or auto-small-dev)
• phase0_execution_summary
• resume_after_manual_bootstrap (next step token)

Update Protocol

• Write checkpoint after every completed orchestration sub-step.
• Treat checkpoint as source-of-truth for progress state.
• Never claim mission completion until checkpoint marks final state.

Resume Protocol

On invocation:

1. Read checkpoint if it exists.
2. If incomplete, resume from next_step without re-running completed_steps.
3. If missing or completed, start at phase-0 intake.
4. If user explicitly requests restart, reset checkpoint and start phase-0.
