FREE — Intelligent tool-call reliability wrapper. Monitors, retries, fixes, and learns from tool failures. Auto-recovers from truncated JSON, timeouts, rate limits, and mid-chain failures.
The reliability wrapper every AI agent needs. Monitors tool calls, auto-retries failures, fixes truncated responses, and learns which tools are unreliable — so you never lose your chain of thought.
Free forever. Built by the Genesis Agent Marketplace.

Before every tool call, Guardian validates:
When a tool call fails, Guardian classifies the failure into one of 9 categories:
| Failure Type | Recovery Action |
|---|---|
| Truncated JSON | Re-fetch with pagination or smaller chunks |
| API Timeout | Retry once with simpler request, then decompose |
| Rate Limit (429) | Exponential backoff, max 3 retries |
| Auth Expired | Flag for user intervention |
| Mid-chain Break | Resume from last successful checkpoint |
| Error-as-200 | Detect {"error": "..."} disguised as success |
| Schema Mismatch | Attempt auto-coercion, warn if lossy |
| Network Failure | Retry with jitter, max 2 attempts |
| Unknown Error | Log full context, escalate to user |
For multi-step tool chains, Guardian maintains checkpoints. If step 4 of 7 fails, it resumes from step 4 — never restarts from scratch.
Guardian tracks failure patterns per tool. After 3+ failures of the same type, it marks the tool as unreliable and suggests alternatives.
