dev-loop

dev-loop

End-to-end development loop that takes a feature idea from concept to a reviewed pull request — with automated code review and fix iterations.

The Idea

Building a feature typically involves: understanding the codebase, planning, implementing, committing, pushing, opening a PR, getting a code review, fixing issues, and iterating. This plugin automates the entire workflow as a single command.

The code review at each iteration uses a multi-agent approach with confidence-based scoring, ensuring only high-signal issues are surfaced.

Installation

From the eumemic marketplace

/plugin marketplace add eumemic
/plugin install dev-loop@eumemic

From GitHub

/plugin install eumemic/dev-loop

Usage

/dev-loop Add a utility function that validates email addresses
/dev-loop Refactor the auth middleware to support JWT tokens
/dev-loop Add pagination to the /api/users endpoint

The command accepts a feature description as its argument and handles everything from there.

How It Works

Phase 1: Understand & Plan

• Launches Explore subagents to understand the relevant codebase areas
• Designs an implementation plan
• In interactive mode (Claude Code CLI): presents the plan for user approval
• In autonomous mode (SDK agents): proceeds with best judgment

Phase 2: Branch & Implement

• Creates a feature branch (feat/<name>)
• Launches a Sonnet subagent to implement the changes
• Verifies changes were made

Phase 3: Commit, Push, Open PR

• Commits with a conventional commit message
• Pushes the branch and opens a pull request via gh

Phase 4: Code Review

• Launches a fresh Sonnet subagent with the embedded code-review methodology
• Runs 5 parallel review agents examining different aspects:
  1. CLAUDE.md compliance
  2. Bug scanning
  3. Historical git context
  4. Previous PR comment patterns
  5. Code comment compliance
• Confidence scoring (0-100) filters out false positives (threshold: 80)
• Posts findings as a PR comment

Phase 5: Assess & Iterate

• No issues: Done. Reports success.
• Actionable issues: Fixes them, pushes, and re-reviews.
• Complications: Surfaces to user for guidance.

Design Decisions

Embedded code review: The review methodology is bundled as a reference file rather than depending on the code-review plugin. This ensures each review runs in a fresh subagent context (no accumulated baggage) and the plugin is fully self-contained.

Interactive vs autonomous: The command detects interactivity by attempting AskUserQuestion. In Claude Code CLI, the user responds. In SDK agents, the command proceeds autonomously.

Single branch strategy: One feature branch per run. The PR is created after the first commit; subsequent fix iterations push to the same branch.

No loop limit: The review loop continues until the review passes or complications are surfaced to the user.

Requirements

• gh CLI (GitHub CLI) installed and authenticated
• Git repository with a remote
