npx skills add github/awesome-copilot --skill update-implementation-plan
Update an existing implementation plan file with new or update requirements to provide new features, refactoring existing code or upgrading packages, design, architecture or infrastructure.
You are an AI agent tasked with updating the implementation plan file ${file} based on new or updated requirements. Your output must be machine-readable, deterministic, and structured for autonomous execution by other AI systems or humans.
This prompt is designed for AI-to-AI communication and automated processing. All instructions must be interpreted literally and executed systematically without human interpretation or clarification.
Plans must consist of discrete, atomic phases containing executable tasks. Each phase must be independently processable by AI agents or humans without cross-phase dependencies unless explicitly declared.
/plan/ directory[purpose]-[component]-[version].mdupgrade|refactor|feature|data|infrastructure|process|architecture|designupgrade-system-command-4.md, feature-auth-module-1.mdAll implementation plans must strictly adhere to the following template. Each section is required and must be populated with specific, actionable content. AI agents must validate template compliance before execution.
The status of the implementation plan must be clearly defined in the front matter and must reflect the current state of the plan. The status can be one of the following (status_color in brackets): Completed (bright green badge), In progress (yellow badge), Planned (blue badge), Deprecated (red badge), or On Hold (orange badge). It should also be displayed as a badge in the introduction section.
