local-implementation

What problem does it solve?

This Skill eliminates inconsistent and error-prone local dev loop phase execution by providing deterministic phase planning, test-first implementation workflows, and mandatory validation guardrails, ensuring teams never skip required acceptance criteria or artifact steps when turning GitHub issues into merged PRs.

Core Features & Use Cases

• Deterministic Phase Planning: Generates 2-3 implementation plan variants, merges them into a reviewed phase plan, and delegates tasks to specialist subagents to avoid scope creep and missing requirements.
• Test-First Implementation Guardrails: Enforces 90% test coverage thresholds, pre-flight worktree and branch validation, and pre-approval review fan-out to catch issues before merge.
• Flexible Session Support: Works with both phase-document-backed and tracker-backed local implementation sessions, automatically bootstrapping missing support files as needed.
• Use Case: For example, when implementing a new feature branch for a GitHub issue, use this Skill to plan the phase, write tests first, run all required validation gates, and produce the correct phase artifacts without manual coordination of each step.

Quick Start

Use the local-implementation skill to execute the current dev loop phase, including phase planning, test-first implementation, all required validation gates, and mandatory phase artifact maintenance.
