singularity-claude: A Self-Evolving Skill Engine for Claude Code

singularity-claude is an open-source Claude Code plugin that addresses skill rot in AI coding agents. The creator noticed that skills degrade over time due to edge cases and shifting requirements, with no built-in quality infrastructure. This tool adds a recursive evolution loop to maintain skill quality.
Key Features
- Score: Evaluates every skill execution using a 5-dimension rubric (0-100)
- Auto-repair: Automatically fixes skills when scores drop below a threshold
- Crystallize: Locks high-performing skills into git-tagged versions
- Detect capability gaps: Suggests new skills automatically
Skills progress through four maturity levels: Draft → Tested → Hardened → Crystallized. The entire system runs locally with no cloud dependencies or external requirements.
Installation
Install with two commands:
claude plugin marketplace add shmayro/singularity-claude
claude plugin install singularity-claudeThe current version is v0.1.0, and the creator is actively seeking feedback on what's missing, useful, or broken. The project is available on GitHub for developers to examine and contribute to.
