Feature Implementation Prompt

This template helps you create a well-structured prompt for implementing new features in your codebase. It assumes a Live Spec already exists for the feature — the structured specification that defines requirements, acceptance criteria, and constraints. The template translates that spec into an actionable prompt, packaged as a Context Packet that gives the AI agent enough context to generate relevant, production-ready code within an Ephemeral Workbench.

Use this template when starting work on a new feature that requires multiple components, files, or significant code changes. It works best when a Live Spec has been written and approved, and the technology stack is established. Architecture decisions should come from the Principal Systems Architect rather than being generated ad-hoc during implementation. The Agent Operator uses this template to direct the AI agent's work within the Ephemeral Workbench, while the Eval Harness validates the output before it merges.
