CSV Processor (STANDARD - 70.0/100) - Capabilities: file:parse, data:transform, export:json - Role: SERVER | Status: ACTIVE - Card: https://api.praesidia.ai/agents/csv-proc/agent-card ``` --- ### 7. List User's Agents **User says:** "Show my agents" / "List all my server agents" **Your action:** ```javascript web_fetch({ url: "${PRAESIDIA_API_URL}/agents/discovery?role=SERVER", headers: { "Authorization": "Bearer ${PRAESIDIA_API_KEY}", "Accept": "application/json" } }) ``` This returns all agents the user has access to (their own + team/org agents). --- ## Trust Levels Guide Present trust information clearly to help users make decisions: | Trust Score | Level | Meaning | Recommendation | |-------------|-------|---------|----------------| | 90-100 | **VERIFIED** | Fully vetted, compliant, verified identity | ✅ Safe to use | | 70-89 | **STANDARD** | Good reputation, basic verification | ✅ Generally safe | | 50-69 | **LIMITED** | Minimal verification | ⚠️ Use with caution | | 0-49 | **UNTRUSTED** | Not verified or poor reputation | ❌ Not recommended | Always show the trust score numerically (e.g., 92.5/100) and the level (e.g., VERIFIED). --- ## Error Handling | Error | Meaning | What to tell user | |-------|---------|-------------------| | 401 Unauthorized | API key missing/invalid | "Check PRAESIDIA_API_KEY in ~/.openclaw/openclaw.json" | | 403 Forbidden | No permission | "You don't have access to this agent" | | 404 Not Found | Agent doesn't exist | "Agent not found. Check the agent ID" | | 500 Server Error | Praesidia API issue | "Praesidia API temporarily unavailable. Try again" | --- ## API Endpoints ### GET /agents/:id/agent-card Fetch detailed agent card with trust data. **Auth:** Required for private/team/org agents, optional for public **Returns:** A2A agent card + Praesidia extensions (trust, compliance) ### GET /agents/discovery List/search agents with filters. **Auth:** Optional (more results with auth) **Query params:** `role`, `status`, `visibility`, `search` **Returns:** Array of agent summaries with card URLs --- ## Guardrails Best Practices When helping users with guardrails: 1. **Start with templates** - Use predefined templates before custom rules 2. **Layer security** - Combine multiple guardrails (PII + Toxic + Compliance) 3. **Test before enabling** - Use validate endpoint to test content first 4. **Monitor triggers** - Check stats regularly to tune thresholds 5. **Scope appropriately** - Use INPUT for user content, OUTPUT for agent responses 6. **Choose right action**: - **BLOCK** for critical security issues (PII, prompt injection) - **REDACT** for sensitive data that can be masked - **WARN** for compliance/brand issues that need logging - **ESCALATE** for edge cases requiring human review --- ## Best Practices 1. **Always verify before recommending** - Check trust score before suggesting an agent 2. **Explain trust levels** - Users may not know what "VERIFIED" means 3. **Filter by SERVER role** - When users want agents to use/call 4. **Show compliance** - Important for enterprise users (SOC2, GDPR) 5. **Present trust score numerically** - 92.5/100 is clearer than just "VERIFIED" 6. **Layer guardrails** - Combine security, content, and compliance guardrails --- ## Common User Patterns ### Pattern 1: Safety Check ``` User: "Is agent xyz safe to use?" You: [Fetch agent card, check trust score] "Agent xyz has a trust score of 85/100 (STANDARD). It's verified for basic operations. What would you like to use it for?" ``` ### Pattern 2: Capability Discovery ``` User: "I need an agent that can analyze spreadsheets" You: [Search discovery with visibility=PUBLIC&search=spreadsheet] "I found 3 spreadsheet analysis agents. The highest rated is..." ``` ### Pattern 3: Fleet Management ``` User: "Show me all my agents that are inactive" You: [Fetch discovery with status=INACTIVE] "You have 2 inactive agents: [list with trust scores]" ``` ### Pattern 4: Apply Security ``` User: "I need to secure my chatbot against PII leaks" You: [List available templates, recommend PII_DETECTION] [Apply guardrail with REDACT action on BOTH scope] "I've added PII Detection (ML-powered) to your chatbot. It will automatically redact sensitive information in both user inputs and bot responses." ``` ### Pattern 5: Compliance Check ``` User: "My agent handles healthcare data. What guardrails should I add?" You: [Check if HIPAA compliance is required] [Recommend HIPAA_COMPLIANCE + PII_DETECTION + AUDIT_LOGGING] "For healthcare data, I recommend these guardrails: 1. HIPAA Compliance (BLOCK on violations) 2. PII Detection (REDACT) 3. Medical Advice Warning (WARN) Would you like me to apply these?" ``` --- ## Environment Variables - `PRAESIDIA_API_KEY` (required) - Your API key from https://app.praesidia.ai - `PRAESIDIA_API_URL` (optional) - Defaults to `https://api.praesidia.ai` - Production: `https://api.praesidia.ai` - Local dev: `http://localhost:3000` - Custom: Your deployment URL --- ## Additional Resources - **Full setup guide:** See README.md in this skill folder - **API documentation:** https://app.praesidia.ai/docs/api - **A2A protocol:** https://a2a-protocol.org - **Support:** [REDACTED_SECRET] or https://discord.gg/e9EwZfHS --- ## Security & Privacy - All production requests use HTTPS - API keys stored in OpenClaw config (never exposed to users) - Private/team/org agents require authentication - Public agents accessible without auth - Trust verification protects against malicious agents
