Feature Development

Goal

Build features with a clear, reviewable flow: understand first, design second, implement third, verify last.

Workflow

1. Discovery

• Restate the feature in plain language.
• Identify success criteria, constraints, and unclear details.
• Ask questions before designing if important behavior is unspecified.

2. Codebase Exploration

• Read the most relevant files and similar features.
• Reuse existing patterns for architecture, UI, state, tests, and naming.
• Note extension points and project conventions before proposing changes.

3. Design

• Present one recommended approach or 2-3 approaches if trade-offs are meaningful.
• Explain the impact on files, behavior, tests, and user experience.
• Get user approval before implementation.

4. Implementation

• Keep scope aligned with the approved plan.
• Prefer incremental edits over broad refactors.
• Add or update tests when behavior changes.
• For design-heavy UI work, combine with frontend-design after the approach is approved.

5. Review And Verification

• Self-check for regressions, accessibility issues, and confusing behavior.
• Run the most relevant validation steps for the change.
• Use code-review for a focused review if the task is non-trivial.

6. Summary

Report:

• What was built
• Key assumptions or decisions
• What was verified
• Any remaining risks or follow-up work

Output Structure

When helpful, organize responses as:

• Summary
• Questions or assumptions
• Proposed approach
• Implementation
• Verification
