Wraps tool calls with automatic retry, failure classification, truncated JSON recovery, rate-limit backoff, and chain checkpointing. Use when tools timeout, return malformed responses, or break multi-step agent workflows.

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.

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.
@recallmax - Long-context memory enhancement (also free from Genesis Marketplace)npx claudepluginhub sickn33/antigravity-awesome-skills --plugin antigravity-bundle-aas-mobile-app-builderWraps tool calls for reliability: monitors failures, auto-retries with backoff, fixes truncated JSON/timeouts/rate limits, resumes mid-chain from checkpoints, learns unreliable tools. Use for robust AI agent workflows.
Implements circuit breaker logic for agentic tool calls: tracking tool health, transitioning states, reducing scope on failure, and routing to alternatives via capability maps. Use when building fault-tolerant agents with multiple tools.
Provides error classification by severity/recoverability, recovery strategies, logging, and handlers for auth/rate-limit/timeout errors in resilient services.
