That's it. No API wrappers. No config files (for most plugins). Just install and talk to Claude naturally.
Why This Exists
AI plugins today have a trust problem. Most are demos — not production tools. They hardcode credentials, skip confirmation on destructive actions, and have no concept of agent boundaries.
We built SOSA™ (Supervised Orchestrated Secured Agents) to fix that — a four-pillar methodology for production-grade autonomous AI operations. Every plugin in this marketplace declares its compliance level, impact classification, and security posture.
The four pillars:
| Pillar | In Practice |
|---|
| 🛡️ Supervised | High-impact actions require human approval. An outreach agent can't send 500 emails without your sign-off. |
| ⚙️ Orchestrated | Agents follow Plan → Act → Verify. Token budgets are enforced — bloated skills waste your money. |
| 🔒 Secured | No hardcoded credentials. External data is scanned for prompt injection. Package versions pinned. |
| 🤖 Agents | Each agent has a formal role spec, declared tool access, and explicit boundaries. A finance agent can't send emails — period. |
