Treats `best_skill.md` as the adapter: trajectory-driven edits, textual learning-rate budget, validation gate, deployable artifact. BYO LLM backends (OpenAI/Azure/Claude/Qwen/…). SkillOpt-Sleep companion for offline session harvest. Not a paid wall — bring your own keys and verifiers.","theCatch":"★17,883 in about 70 weeks (~255 a week): judge it on the optimizer loop, not the star count. Vs Superpowers / agent-skills (Addy) / Matt Pocock skills packs: those ship hand-authored SKILL.md workflows and session methodology; SkillOpt trains/evolves skills as parameters for frozen agents. Training burns provider tokens; plugin shells for Claude/Codex/etc. live in-repo more than in the PyPI wheel.","verdict":"MIT skill trainer when frozen agents need evolved skill.md — not another hand-pack; ignore the star spike.","addedAt":"2026-09-30","featured":false,"domain":"AI Agents","subSpecialty":"Skills","subcategory":"Skills","tags":["self-host","local-first","permissive","skills","active","young-repo","fast-stars"],"capabilities":["skills","optimizer","agents"],"surfaces":["Self-host","Hosted"],"ecosystem":["Python","Multi-platform"],"licenseModel":"OSS/MIT","githubStars":18545,"starsPerWeek":789,"access":"free","archived":false,"repo":{"createdAt":"2026-05-08","pushedAt":"2026-10-18","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/skillopt","html":"/gems/skillopt","markdown":"/gems/skillopt.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
