SkillSealSkillSealThe skills market is the Wild West — 36% contain prompt injection and the average score is 6/12. SkillSeal tests every skill in an isolated environment and certifies that it actually works. Install with confidence.
Every skill passes 3 layers before earning the seal.
Valid YAML frontmatter, complete SKILL.md, referenced scripts exist. No half-baked skills.
Runs the skill in an isolated Docker container and verifies the output matches expectations. Proves it works, not just that it "seems fine".
Scans for env var reading, network requests, reverse shells, destructive commands, and obfuscated payloads.
Tested and approved by SkillSeal.
Turns your agent into a performance DBA. Analyzes EXPLAIN plans, detects slow queries (Seq Scan, Nested Loop, disk sorts, low work_mem) and suggests concrete fixes. Knowledge from the PostgreSQL Mastery ebook (216 chapters).
Agent specialized in creating and optimizing n8n automations — workflows, integrations, AI agents and production. Based on the n8n Mastery ebook.
Upload your skill and we'll test it. Get the seal if it passes.
Your skill must follow the standard agentskills.io structure. Submit either:
SKILL.md must have YAML frontmatter: name, description, version.
If your skill has no executable script, we'll validate structure + security and rate it as "structure-only".
The SkillSeal certification engine is MIT-licensed and open for anyone to use, modify and build on.
