Agensi: A SKILL.md Marketplace Built with Claude in 3 Weeks
Agensi is a marketplace for SKILL.md skills that was built almost entirely using Claude over three weeks. The project combines Claude Code with Lovable and Supabase for infrastructure.
How Claude Built This
Claude handled multiple aspects of the project:
- Wrote legal documents including terms of service, privacy policy, and DMCA policy
- Designed an automated security scanner that checks every uploaded skill for malicious patterns
- Generated the initial batch of free skills available on the platform
- Wrote edge functions for download fingerprinting and piracy reporting
- Helped architect the bounty system
- Created drafts for Reddit posts about the project
Current Platform Status
After three weeks, Agensi has:
- 37 skills listed across 8 categories
- Close to 200 downloads
- 100-200 unique visitors daily
- Skills ranging from a $30 Blender 5 Python scripting skill (handles breaking API changes) to free developer utilities like a code reviewer and environment doctor
Recent Additions
Since the initial launch, the developer has added:
- A learning center with guides on creating skills, installing them, and comparisons between SKILL.md, Cursor rules, and Codex skills
- A compatibility system where creators declare which agents they tested their skills on
- A bounty request system where users can post skills they want, set a price, and creators can build them
The site is free to browse with many free skills available. Paid skills allow creators to set their own prices and keep 80% of the revenue.
