AI writes the code. You design the system.
Battle-tested Claude Code plugins, curated from daily use.
Installation • Plugins • Philosophy
Most plugins in the wild are vibe-coded in an afternoon and never touched again.
These are different.
Every command in this marketplace comes from real, daily usage — refined over months, not as experiments, but as core tools in an actual development workflow.
- Curated — Only what survives daily use makes it here
- Updated — Continuously improved based on friction points
- Tested — Used hundreds of times across real projects
- Minimal — No bloat, no clever abstractions, just what works

Ralph-Loop is a premium plugin included in the DevX Course.
| Type | Name | Purpose |
|---|---|---|

Generate structured plan with verifiable predicates |
| Command | /devx-ralph:ralph |
Execute the agentic loop until all predicates pass |
| Command | /devx-ralph:archive |

Deep codebase analysis for planning context |
Orchestrator mode — Run with isolated sessions to avoid context rot, auto-commit after each task, token efficient.
Battle-tested — Every command exists because it solved a real problem, repeatedly.
Opinionated — Conventional commits. Proper PR descriptions. ASCII diagrams. Decisions are made so you don't waste time configuring.
Honest — If something doesn't work well, it gets fixed or removed.
Minimal — No dependencies. No build steps. Just markdown that Claude understands.
Built by Pierre Tomasina — building tools for AI-native development.
Dev3o — Teaching developers the 10% that AI can't figure out.
