Self-checking agents fail: should you build an independent verifier for AI agent tasks?
1982_miguel · reddit · 2026-10-21
A Reddit user poses an agent-engineering question: agents often declare "task completed" while skipping business rules. Having the same model self-audit via a detailed Skill invites confirmation bias — if it erred executing, it errs auditing. They propose an independent verifier (small model, deterministic rules, or hybrid flow) that checks requirements one by one and outputs structured verdicts, e.g. "30 days required / 25 proposed → pass; $5M guarantee required / $3M found → fail." Core question: does an independent verifier actually beat skill-based self-checks on precision, and is the extra token cost and latency worth it? The thread solicits production-experienced tools, frameworks, and MCP suggestions.
