The tool indexes repositories locally via Codebase Memory MCP (SQLite + ZSTD graph database) and Serena LSP, computing a mathematical blast radius before any code change and halting edits to high-degree hub or bridge nodes. It enforces a RED→GREEN→REFACTOR TDD cycle, schedules tasks as a Wave DAG with isolated git worktrees, and runs across five agent platforms under the MIT license.", "body_md": "Most AI coding agents (Claude Code, OpenAI Codex, OpenCode, DeepSeek Harness) write code fast, but they break architectures in large production codebases.\n\nHere are the 3 biggest problems with raw agents:\n\nTo fix this, I created **[Supergraph](https://github.com/datit309/supergraph)** — an open-source workflow and orchestration engine for AI coding agents.\n\nSupergraph enforces a strict 8-step engineering lifecycle on every task:\n\n`scan → analyze → plan → TDD → execute → fix → verify → review`\n\nPowered by **Codebase Memory MCP** (SQLite + ZSTD graph database) and **Serena LSP**, Supergraph indexes your repository locally. Before proposing a single code change, it calculates the mathematical blast radius. If you attempt to modify a high-degree hub node or bridge node, it flags the risk immediately and halts reckless edits.\n\nSupergraph enforces a strict **RED → GREEN → REFACTOR** cycle:\n\n`supergraph-team`)\nFor complex features or refactors, Supergraph schedules tasks as a Wave DAG. Each agent worker claims an isolated git worktree branch. Tasks execute in parallel without dirtying your main working tree. A verification gate checks tests and linter before merging back into main, with a live status dashboard running at `http://localhost:3333`.\n\n`browser-agent`)\nBuilt on native Rust CDP (`agent-browser`, zero Playwright bloat). It bypasses anti-bot defenses using real browser profiles, captures token-efficient Accessibility Tree snapshots (`@ref`), and executes 5-dimension ISTQB test matrices (UI + API + database fault injection).\n\n`caveman` mode)\nBuilt-in prompt engineering and tool-result pruning strip conversational fluff while keeping code and terminal outputs technically exact, saving token costs across multi-hour sessions.\n\nSupergraph runs identically across 5 agent platforms:\n\nInstall in one command (macOS/Linux/WSL):\n\n```\ncurl -fsSL https://raw.githubusercontent.com/datit309/supergraph/master/install.sh | sh\n```\n\nOr on Windows PowerShell 5.1+:\n\n```\nirm https://raw.githubusercontent.com/datit309/supergraph/master/install.ps1 | iex\n```\n\nStart your session with:\n\n```\n/supergraph:scan       # Ingest graph context\n/supergraph:analyze    # Risk & blast radius check\n/supergraph:plan       # Generate DAG plan\n/supergraph:execute    # Parallel git worktrees execution\n```\n\nSupergraph is 100% open-source under the MIT license:\n\n⭐ **GitHub Repository:** [https://github.com/datit309/supergraph](https://github.com/datit309/supergraph)\n\nIf you find this approach useful, please drop a Star on GitHub!
