Keel: A Multi-Agent Workflow Framework That Turns Coding Agents into Work Owners

Keel is a project-agnostic multi-agent workflow skeleton that drives GitHub Issues from to-do items to merged completion, enabling end-to-end automation covering requirement understanding, branch creation, code implementation, CI waiting, code review, test validation, and secure merging.

Section 01

Keel: A Multi-Agent Workflow Framework for End-to-End Issue-to-Merge Automation

Keel is a project-agnostic multi-agent workflow backbone that automates the full lifecycle from GitHub Issue creation to PR merge—covering requirement understanding, branch creation, code implementation, CI waiting, code review, test validation, and secure merging. It fills gaps in existing tools by integrating coding agents, review tools, quality gates, and merge strategies into a unified work ownership framework.

Section 02

Background & Motivation for Keel

Existing coding agents (OpenHands, SWE-agent, Devin) stop at PR creation; PR review tools (CodeRabbit, PR-Agent) focus on existing PRs; merge queue tools (GitHub Merge Queue, Mergify) handle post-test merging. None cover the complete issue-to-merge lifecycle. Keel was built to bridge this gap as a unified workflow backbone.

Section 03

Core Architecture & 13-Step Workflow

Keel uses a 3-layer design: Layer1 (fixed keel-core backbone), Layer2 (project-specific config via project.yaml), Layer3 (add-only extensions). Its 13-step workflow includes key stages: implement (coding agent works), classify (risk grading), review (multi-agent via ai-jury), merge (security strategies like time zone locks), and capture (learning accumulation).

Section 04

Keel vs. Existing Tools

Keel complements rather than replaces existing tools:

  • Adds lifecycle management beyond PR creation for coding agents.
  • Extends PR review tools with implementation loops and merge strategies.
  • Provides issue ownership (pre-PR) for merge queue tools. It acts as a work ownership skeleton integrating these tools into a unified lifecycle.

Section 05

Installation, Commands & Quality Assurance

Installation: pip install keel-workflow (Python ≥3.11). Key commands: setup (project config), validate (config check), plan (workflow preview), ship (flagship command). Keel uses dogfooding (self-development via its own workflow) and maintains 100% test coverage for core packages.

Section 06

Real-World Application Scenarios

  1. Automated Issue Handling: End-to-end processing from issue creation to merge without manual intervention.
  2. Nightly Regression Testing: overnight command runs tests, checks dependencies, and creates issues for problems.
  3. Multi-agent Code Review: Integrates ai-jury to run multiple agents for comprehensive code reviews.

Section 07

Summary & Future Vision

Keel v1 focuses on single-agent work ownership. Long-term vision: Autonomous software teams (multiple agents under human supervision). It frees developers from routine tasks to focus on human-judgment work (product tradeoffs, approvals). Keel is key infrastructure connecting human intent and machine execution in software engineering automation.
