Build your agent skill stack (before your competitors do)

The agent skills ecosystem went from one registry to eight marketplaces in six months. Knowing how to evaluate, install, and combine skills is itself a skill.

Outcome

Replace a slice of your SaaS bill with a curated, auditable set of agent skills.

Best for

Solo operators already using Claude or other agents daily who want compounding leverage

What changed

The agent skills ecosystem grew from one registry in December 2025 to eight major marketplaces by Q2 2026 — skills.sh (Vercel-backed, npm-style), ClaudeSkills.info (650+ free, community-run), and Agensi (vetted, paid) are the practical trio. Anthropic's Claude for Small Business now ships with 15 ready-to-run workflows, which tells you where this is heading: skills are becoming the unit of business automation.

How to build the stack

List your recurring tasks; mark anything you do weekly that follows the same shape.
Browse one free registry and one vetted marketplace — don't try to track all eight.
Evaluate before installing: read the skill's instructions like you'd review a contractor's SOW. Trust and curation matter more than feature lists.
Install 3 skills, run them on real work for a week, keep what earns its place.
Write your own skill for the one workflow no marketplace covers — that's your moat.

The economics

The pitch that matters for a solo operator: $30–50 in one-time skill purchases can replace $200/mo in single-purpose SaaS. Audit your subscriptions against what a skill plus a frontier model could do.
