I will write vapi retell ai prompt guardrails to stop hallucinations


About this gig
Is your AI voice agent making up fake pricing tiers, quoting wrong appointment times, or getting stuck in infinite loops? Overstuffed system prompts make voice bots erratic, slow down response speeds, and create severe legal liabilities for business owners.
I specialize in building bulletproof system prompt guardrails and conversational architectures for Vapi, Retell AI, and Bland AI setups. I will clean up your core instructions so your voice bot handles out-of-scope questions cleanly, avoids hallucinations, and protects your database webhooks.
What I deliver:
- Build rigid prompt guardrails to completely eliminate unauthorized voice agent hallucinations
- Compress overstuffed system prompts to speed up response latency and crush your token costs
- Design a seamless "Dead End" safety routing protocol to push out-of-scope calls to human managers
- Secure your GoHighLevel CRM integration by locking tool calling commands to verified data blocks
- Prevent prompt injection vulnerabilities to keep malicious callers from stealing your company lists
Protect your business from an erratic voice bot. Message me today to build strict prompt guardrails!

FAQ
Q: Why is my AI voice agent hallucinating information not found in its script?
A: This happens when you dump too much unformatted text into the system instructions. This causes token drift. I solve this by building hierarchical prompt guardrails that force the voice bot to strictly use a verified knowledge base.
Q: How do your prompt guardrails handle rude or uncooperative callers?
A: I write strict behavioral conditional blocks. If a user tries to hijack the system or uses toxic language, the voice agent triggers a safe termination script or routes the caller to a real human manager via a Twilio transfer tool.
