Codebase harness + loop engineer

What it solves

This project provides a marketplace of plugins for Claude Code designed to transform coding agents from task-by-task prompt-driven tools into "loop engineers." These agents can be triggered automatically, perform work, verify their own results, and maintain a shared, file-based memory to allow work to compound over time across different agent loops (e.g., SEO, product, and support).

How it works

The system relies on four primary components to create autonomous loops:

  1. Triggers: Mechanisms like crons or webhooks that wake the agent.
  2. Shared Memory: A file-based knowledge base (managed by the new-loop skill) where agents read and write logs and architecture notes.
  3. Tools: MCPs and other skills that allow the agent to interact with the world.
  4. Codebase Harness: A set of skills (orchestrated by setup-codebase-harness) that allow agents to run, test, and verify code in isolated environments, including support for parallel cloud stacks via Crabbox.

Additionally, it includes utility skills for auditing agent context against Anthropic's guidance, delegating tasks to other CLI agents via tmux, and generating visual flow diagrams or video captions.

Who it’s for

Developers and AI builders who use Claude Code and want to build autonomous, compounding agentic workflows rather than manually prompting every step of a software development lifecycle.

Highlights

  • Compounding Loops: Enables multiple agents to share a single "brain" via a shared folder structure, allowing one agent's findings to inform another's work.
  • Codebase Harness: Automates the setup of local dev stacks, e2e tests, and isolated cloud boxes for parallel agent execution.
  • Agent Context Audit: A specialized tool to find overconstraints and redundancies in CLAUDE.md and documentation based on Claude 5 guidance.
  • Open Agent Teams: A protocol for delegating work to any CLI agent (such as Grok or Aider) using detached tmux sessions.
