SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires validate_plan_authority.py, validate_tracked_plan.py, read_tracked_plan.py, validate_plan_event.py, read_plan_events.py, validate_execution_surface.py, read_execution_surface.py, and includes scripts (resource) components.

What problem does it solve?

This Skill orchestrates the execution phase of the plan workflow by consuming the authoritative plan pointers and ensuring runtime state updates are append-only, avoiding modification to stable plan intent.

Core Features & Use Cases

  • Consumes the authoritative Linear issue pointer and the canonical linked-tracked-plan; validates alignment, and updates only runtime state fields on tracked-plan/1; appends progress events rather than rewriting history.
  • Enforces hard gates and blockers; validates presence of plan-authority/1 and linked-tracked-plan; cross-surface consistency checks and safe execution.
  • Use Case: resume execution from the latest plan state after plan mode; continue execution when new plan events occur.

Quick Start

Provide a Linear issue with a valid plan-authority envelope and a linked tracked-plan, then trigger execution to resume or continue the plan.

FAQPage Schema
How do I resume execution of a tracked plan from the latest state?

To resume tracked plan execution, provide a Linear issue with a valid plan-authority envelope and a linked tracked-plan. The Skill consumes these authoritative pointers, validates alignment, and updates runtime state by appending progress events rather than rewriting history.

What is plan drift and how do I prevent it during plan execution?

Plan drift occurs when runtime state diverges from the original plan intent. Prevent plan drift by validating the linked tracked-plan and plan-authority envelope alignment before execution, ensuring runtime state updates remain append-only and never modify stable plan intent.

Do I need helper scripts to execute a tracked plan workflow?

Yes, tracked plan execution requires helper scripts to read, validate, and append progress events. These scripts validate the plan-authority envelope, linked tracked-plan, and execution surface to guard against invalid cross-surface states during runtime.

Can I continue plan execution when new plan events occur without restarting?

Yes, you can continue plan execution when new plan events occur by triggering the execution Skill. It reads the latest plan events, validates the execution surface, and resumes from the current runtime state without modifying the original tracked-plan intent.

What are the limitations of append-only plan execution?

Append-only plan execution prevents modification of stable plan intent, meaning historical progress events cannot be rewritten. Execution is blocked if the plan-authority envelope or linked tracked-plan is missing, or if cross-surface consistency checks fail.

Does plan execution work with Linear issue pointers for workflow validation?

Yes, plan execution consumes the authoritative Linear issue pointer as part of workflow validation. It cross-references the Linear issue with the canonical linked tracked-plan and plan-authority envelope to ensure safe execution and prevent invalid cross-surface states.
