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.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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. ## Install ```bash npx skills add christopherlhammer11-ai/tool-use-guardian ``` ## 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 | | API Timeout | Retry once

Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
