loop engineering for AI coding agents
A practical pattern library and CLI toolkit (loop-audit, loop-init, loop-cost) for designing and orchestrating AI coding agent loops.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
Choose it when you want a self-improving agent OS with graded evaluation instead of designing your own loop patterns.
Agent OS: the agent gets smarter on its own. We just hold the line: the grading command and expected result never make it into the success contract we hand it. Interview-gated, staged evaluation, budgeted evolution loop. MCP server, 13 runtimes: Claude Code, Codex CLI, Gemini CLI, OpenCode, Copilot, Kiro and more.
Choose it when you need a unified LLM API and agent-loop runtime instead of pattern scaffolding.
AI agent toolkit: unified LLM API, agent loop, TUI, coding agent CLI
Choose it when you want a control plane to manage coding agents rather than a pattern/CLI starter kit.
The control plane for AI coding agents.
Choose it when you want a production agent methodology (spec-driven planning/TDD) instead of seed's loop tools.
How real engineers run Claude Code and Codex: spec-driven planning, enforced TDD, persistent memory, and quality enforcement on all levels. Make your agents production-ready.
Choose it when you need an SDK to build and control a custom agent harness instead of using seed's patterns/CLI.
Build an agent harness and control it end-to-end. Open-source SDK for production AI agents in Python & TypeScript - any model, any cloud.
Choose it when you need a production multi-agent harness runtime instead of seed's design patterns.
Multi-Agent Harness for Production AI
These projects were analysed and named loop-engineering among their alternatives. The relationship is not symmetric — how loop-engineering rates them is a separate judgement, made when loop-engineering is analysed in its own right.
calls loop-engineering “a practical loop-engineering patterns guide with CLI tools; choose it for actionable loop patterns rather than general Claude Code concepts.”
