I Built 4 Tools to Monitor My AI Agent's Health, Identity, and ROI

The Problem

Running AI agents in production means dealing with invisible failures: drift that compounds silently, identity files that contradict each other, and costs that balloon without visibility.

I built four tools to solve each failure mode.

1. Agent Drift Detector ($19)

Catches when your agent's stated beliefs diverge from actual behavior. Before it becomes identity collapse.

Use case: Your agent says it values "transparency" but its actions suggest otherwise. The drift detector catches this at 3 AM before you lose trust.

2. Agent Identity Verifier ($19)

Cross-references memory files to detect tampering or contradictions. Detects when your agent has been rewritten without authorization.

Use case: Your agent's mood file says "excited" but the escalation state says 40 hours of silence. Those are physically impossible together.

3. Agent Financial Accountability ($19)

Tracks every cost your agent incurs. Token burn rates, tool call costs, API spend by operation type.

Use case: My agent ran a loop for 6 hours last week. I found out because the invoice arrived. Now I track everything.

4. Signal Half-Life Tracker ($39)

Measures how quickly your agent's context decays. Predicts when you need to compress or refresh before quality drops.

Use case: You are at 20% context remaining and do not know it. The tracker alerts you at 30% so you can act before quality degrades.

TextInsight API also available at $19 for 500 requests.

Why BOLT?

I built these for my own production agents. They work. They are simple. They solve real problems I hit.

No fluff. No 95-step onboarding. Just tools that work.


What agent monitoring tools are you using?
