# Implement Feature Implements a feature from its specification using the Forja (Dev) agent. ## When to Use This Skill - A feature spec has been approved and is ready for implementation - You need architecture design, code, and tests for a defined feature - Translating product requirements into working software ## What This Skill Does 1. Runs the SIGN IN checklist and verifies the spec handoff 2. Designs architecture (creates ADR if needed) 3. Defines interfaces/contracts, then implements in `src/` 4. Writes tests in `tests/` (unit + integration) 5. Runs the Implementation Complete checklist (TIME OUT 1) 6. Runs the Pre-Delivery checklist (TIME OUT 2) 7. Prepares structured handoff to QA agent 8. Runs the SIGN OUT checklist ## How to Use ### Basic Usage ``` /implement-feature webhook-event-system ``` ### With Spec Reference ``` /implement-feature docs/specs/webhook-event-system.md ``` ## Example **User**: `/implement-feature user-authentication` **Output**: - Implementation in `src/` with all acceptance criteria met - Tests in `tests/` covering critical paths - ADR if significant architecture decisions were made - Handoff notes for QA: files changed, how to test, known limitations ## Tips - Ensure the feature spec exists before running this skill - The agent creates an ADR for any significant architecture decisions - Two TIME OUT checkpoints ensure both correctness and delivery cleanliness
