Tool Use Guardian
Overview
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.

When to Use This Skill
- Use when tool calls return truncated or malformed JSON
- Use when APIs timeout or rate-limit your agent mid-task
- Use when a multi-step chain breaks partway through
- Use when you need automatic retry logic without writing it yourself
- Use for any agent workflow that depends on external tool reliability
How It Works
Step 1: Pre-Call Validation
Before every tool call, Guardian validates:
- Required parameters are present and correctly typed
- The tool is not marked as "unreliable" from previous failures
- Request size is within known limits
Step 2: Failure Classification
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 |
