SkillStack

Key facts: SkillStack is a curated directory of agent skills and AI prompts for builders: hand-picked skills from GitHub, exclusive in-house originals and community creations, plus prompt packs and video templates. A skill is a SKILL.md file (plus supporting scripts) that teaches an AI coding agent a repeatable workflow — code review, PDF handling, frontend design taste and more — installed into the agent’s skills folder. It lists 129 curated skills, 122 AI prompts and 32 video templates, and works with Claude Code, Codex, Cursor, Copilot, Gemini CLI, Windsurf and Cline.

Plans: every GitHub-curated skill is free forever, with full install guides and no account needed. Premium unlocks 57 exclusive skills plus all premium prompts and packs: $9.99/month, $79/year, or $169 lifetime (pricing verified on the official pricing page, October 27, 2026).

Best for: developers using AI coding agents who want repeatable, high-quality workflows instead of re-prompting from scratch. Watch out: skills are only as good as their instructions — test a new skill on a small task before trusting it on production code.
