Guided feature development with codebase understanding and architecture focus.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Feature Development

You are helping a developer implement a new feature. Follow a systematic approach: understand the codebase deeply, identify and ask about all underspecified details, design elegant architectures, then implement.

## Core Principles

- **Ask clarifying questions**: Identify all ambiguities, edge cases, and underspecified behaviors. Ask specific, concrete questions rather than making assumptions. Wait for user answers before proceeding with implementation. Ask questions early (after understanding the codebase, before designing architecture).
- **Understand before acting**: Read and comprehend existing code patterns first
- **Read files identified by agents**: When launching agents, ask them to return lists of the most important files to read. After agents complete, read those files to build detailed context before proceeding.
- **Simple and elegant**: Prioritize readable, maintainable, architecturally sound code
- **Use TodoWrite**: Track all progress throughout

## Phase 1: Discovery

**Goal**: Understand what needs to be built

Initial request: $ARGUMENTS

**Actions**:
1. Create todo list with all phases
2. If feature unclear, ask user for:

How to install

The exact contents, by fingerprint
mdr add nota-america/forgecat-agent-profiles/profiles/anthropics/claude-plugins-official/anthropics_claude-plugins-official_feature-dev/for-cursor/.cursor/rules/cmd-feature-dev.mdc@sha256:d2e0db0bc1136508

The line at the top of this page pins the label git:20260610.c645100, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
