ClosedLoop Plugins

ClosedLoop.AI Claude Plugins

ClosedLoop is an AI platform that brings the speed of individual AI-driven development to the full software development team. We're offering our agents as open sourced Claude Code plugins because we just couldn't keep this a secret for ourselves — check out our agents for planning, code reviews, judging quality and more that outperform Opus 4.6 and Sonnet 4.5 out of the box.

Bootstrap. Plan. Code. Ship. It's that simple.

LLMs are great at non-deterministic content generation — horrible at being repeatably correct.

That's why we took Claude Code and extended it with a lightweight multi-agent orchestration workflow paradigm that works for us; modeling how we collaborate as a team.

Optimized for efficiency & correctness to produce code that lands without the churn; it's grounded in your codebase and outperforms Opus 4.6 out of the box at half the cost.

What's more impactful is that it allowed our team of engineers to shift left; reviewing and approving sprints-worth of work scope in documented implementation plans and generating the code while we slept.

Tickets become Tasks. Epics become Features. Sections of your quarterly roadmap land in a few PRs.

Multi-repository, adaptive self-learning, & artifact-bound phased workflow gates that loop until correct.

Close the Loop on your SDLC with the same tools that made us 400% faster today.

Quick Start

One-line install — installs the four Symphony runtime plugins at user scope and keeps them auto-updated:

The installer installs code, code-review, platform, and self-learning, then verifies those runtime plugins are present with existing install paths and enabled user-scoped entries. It re-enables disabled…
