What problem does it solve? Written implementation plans often get executed inconsistently across sessions: tasks get skipped, progress is lost after context compaction, and verification steps are forgotten. This Skill enforces a disciplined execution loop that loads a plan, reviews it critically, executes every task with verifications, and records progress in a durable git-based ledger. ## Core Features & Use Cases - Durable progress tracking: Writes completed tasks to a ledger under the git directory so execution can resume after session compaction without re-running finished work. - Pre-commit quality gates: Runs design-principles review, karpathy anti-pattern checks, code-documentation requirements, and a linter gate before every task commit. - Conditional skill invocation: Automatically invokes integration-testing for components with external dependencies and observability-standards for new API endpoints. - Use Case: You have a multi-task implementation plan written in a previous session. Invoke this Skill in a fresh session; it resumes from the first incomplete task, executes each step, and finishes with the branch-completion workflow. ## Quick Start Use the executing-plans skill to implement the plan in docs/plans/feature-auth.md, resuming from the progress ledger if one exists.
