Open Giraffe

Pick the high-hanging fruit.

A persistent, daemon-based multi-agent system that leverages opencode to automatically explore, discover, plan, implement, and review code changes across a codebase. Multiple tasks run in parallel, each in its own git worktree, driven by a Project Explorer and a Planner → Coder → Reviewer pipeline with configurable models and retry logic.

Why This Project?

Tools like Cursor and opencode are powerful single-task coding assistants, but they operate in a single conversation at a time — you drive each interaction manually, and parallelism requires you to manage multiple terminal windows or editor tabs yourself. This project fills a different niche:

• Batch autonomy — Submit multiple tasks (or let the system discover them from TODO comments) and walk away. The daemon plans, codes, and reviews them concurrently without human babysitting.
• Continuous project exploration — Set up a free-running Explorer agent that continuously reads your codebase, understands the project structure, and proactively identifies potential refactors, bugs, or missing features.
• Built-in quality gate — Every code change is reviewed by one or more AI reviewers before it's considered done. Failed reviews automatically trigger retries with the reviewer's feedback, creating a self-correcting loop that a single-assistant workflow can't provide.
• Persistent state — Tasks, agent runs, and review history are stored in SQLite. You can stop the daemon, reboot, and resume exactly where you left off. Cursor/opencode sessions are ephemeral.
• Repository-scale isolation — Each task runs in its own git worktree and branch, so parallel tasks never conflict. Publishing is a one-click push.

In short: Cursor and opencode are excellent interactive copilots; this project is an autonomous task queue that orchestrates them at scale.

Key Features

• Continuous Project Explorer (New!) — A free-running agent loop that continuously explores the codebase to understand the overarching structure and business logic. It autonomously identifies potential architectural improvements, hidden bugs, and missing tests without requiring explicit TODO comments.
• Automatic TODO Discovery — Scans a repository for TODO/FIXME comments, then uses an AI analyzer to score each by feasibility and difficulty, producing a prioritized backlog.
• Plan → Code → Review Loop — Each task goes through a planner (generates an implementation plan), a coder (writes code in an isolated worktree), and one or more reviewers (approve or request changes). Rejected code re-enters the loop automatically.
• Multi-Model, Multi-Reviewer — Assign different models by task complexity (e.g. Opus for hard tasks, Haiku for simple ones). Multiple reviewer models vote; all must approve for a task to pass.
• Parallel Execution — Tasks run concurrently in separate git worktree branches, up to a configurable limit.
• Human-in-the-Loop — Completed or failed tasks can be revised with manual feedback, re-entering the code→review loop. A dedicated review-only mode lets you submit patches or PRs for AI review without any code generation.
• Web Dashboard — Real-time dark-themed UI for task management, agent run inspection, TODO browsing, model configuration, and branch publishing.
• Runtime Model Editing — Change planner/coder/reviewer models from the dashboard at any time; changes persist to config.yaml.
• Resource Lifecycle — Worktrees and branches are automatically cleaned up when review-only tasks complete, tasks are cancelled, or via a manual "Clean" action.

Project Explorer — Continuous Analysis Loop

The Explorer agent continuously crawls the codebase, mapping out dependencies, identifying technical debt, and proposing new tasks without needing explicit TODO markers.

These tasks will be automatically prioritized and become tasks ready to be launched.

Agent Runs — Code → Review Loop

Each task cycles through coder and reviewer agents. Reviewer verdicts (APPROVE / REQUEST_CHANGES) are displayed inline. The coder retries with the reviewer's feedback until all reviewers approve or retries are exhausted.

Scanned TODOs — AI-Analyzed Backlog

TODOs are scanned from the repo, then analyzed by an AI model that scores feasibility and difficulty, and writes a detailed analysis note. You can selectively dispatch them as tasks.

Completed tasks can be published (push branch to remote), revised (human sends feedback, loop resumes), or cleaned (worktree + branch deleted).
