Closing the Loop: Why Reactive Agent Analysis Isn't Enough

Last week, Langchain announced their Insights Agent. It automatically analyzes production traces to discover behavioral patterns and failure modes in agentic systems. It's an impressive feature that helps teams understand what's happening inside their agents while they're in production.

It also validates exactly what Wayfound has been doing for the past 18 months.

Reactive analysis is now table stakes in the agent quality space. We pioneered this approach, and we're thrilled to see the market catching up, but we didn't stop there.

The Problem with Analysis Alone

Discovering that your agents have issues is valuable, but discovering issues isn't the same as preventing them. As we've written about before, more AI agents mean more agent slop, and reactive analysis alone doesn't stop low-quality outputs from reaching production. The traditional workflow looks like this: your agents run in production, something goes wrong, users experience failures, analysis tools surface the patterns, a human reads the insights and manually updates prompts or configurations, you redeploy, and you hope the issue is fixed. There's a gap between insight and action, because even with automated analysis, you still need human intervention to close the loop. Your agents can't learn from their own history, can't access the collective wisdom of thousands of previous sessions, and can't query best practices before starting work.

Wayfound's Closed-Loop Innovation

Eighteen months ago, we launched Wayfound with comprehensive reactive analysis capabilities and full session analysis. Our Performance dashboard automatically assesses agents across multiple dimensions including user satisfaction, knowledge gaps, guideline compliance, action success rates, and sentiment. We categorize agent performance into actionable tiers and provide detailed breakdowns of where agents struggle.

Our AI Supervisor automatically generates two types of recommendations: Suggested Behaviors (improvement prompts based on observed patterns) and Suggested Knowledge (identified gaps that could enhance performance). We support multi-agent system supervision using OpenTelemetry traces to provide holistic views of complex workflows. We evaluate complete agent sessions, not just individual turns, tracking full conversation trajectories to assess sustained performance. All of this has been production-ready in Wayfound for over a year, including automated insights from production traces, multi-turn session evaluation, and everything Langchain just announced. But reactive analysis, no matter how sophisticated, only completes half the cycle. The breakthrough came when we closed the loop.

With Wayfound's MCP (Model Context Protocol) integration, the insights we generate from historical sessions become directly accessible to your agents in real-time, not through manual human intervention or deployment cycles, but directly, programmatically, and proactively.

Your agents can now:

• Query quality guidelines before starting work (mcp__wayfound__get_agent_details)
• Access supervisor analysis of common failure patterns (mcp__wayfound__get_supervisor_analysis_for_agent)
• Request improvement suggestions from historical sessions (mcp__wayfound__get_improvement_suggestions_for_agent)
• Submit their work for evaluation during execution (mcp__wayfound__evaluate_session)
• Iterate automatically based on feedback until quality thresholds are met

This is the complete cycle. Historical insights inform real-time prevention and production learnings become development guardrails. The system continuously improves itself.

The Architecture Comparison

Langchain's approach: Production traces → Automated analysis → Insights dashboard → Human reads insights → Manual prompt engineering → Redeploy → Monitor for improvement. 

This is a valuable workflow, but it's also incomplete.

Wayfound's complete cycle: Production traces → Automated analysis → Insights dashboard (same as Langchain), then the closed loop begins: Insights become accessible via MCP → Agents query guidelines and historical learnings before acting → Real-time evaluation during execution → Automatic iteration until quality thresholds met → Prevention of issues before they reach production

The difference is fundamental. One approach tells you what went wrong, the other prevents it from happening in the first place.

And because we use MCP (an open standard), you're not locked into a proprietary platform. Your agents can access Wayfound supervision from any framework that supports Model Context Protocol. Three lines of configuration, and your entire agentic system gains access to 18 months of accumulated wisdom.

Real Example: The Closed Loop in Action

We've open-sourced a working example that demonstrates this closed-loop system. It's a stock research agent that generates investment reports using the Claude Agent SDK. Here's what happens: Before the agent writes a single line of research, it queries Wayfound's supervisor analysis. The response shows that 56% of historical sessions had missing source citations for financial data. The agent also learns about other common issues: internal inconsistencies, incomplete risk disclosures, missing balance sheet metrics. Armed with this knowledge, the agent delegates to specialized sub-agents for research and writing. When the report is complete, it submits the full transcript to Wayfound for evaluation. Result? Grade A on the first submission, with every guideline met, every historical issue proactively avoided, and zero production failures.

‍

The entire integration required three lines of MCP server configuration. No framework changes. No complex instrumentation. Just a connection to the supervisor, and suddenly your agents have access to institutional memory. The complete example is available on Github where you can clone it, run it, and see the closed loop in action.

What This Means for Your Team

If you're still manually reviewing agent traces and hand-crafting prompts, you're already behind. The competitive advantage now comes from closing the loop: building systems that don't just discover issues but prevent them, agents that learn from collective history rather than just individual sessions, and quality gates that operate during development and execution rather than after production failures. Wayfound has been building this complete cycle for 18 months. We pioneered reactive analysis in the agent quality space. While others are catching up on insights and pattern detection, we're solving the harder problem: turning insights into prevention. We're not just monitoring your agents, we're making them better automatically, continuously, and proactively.

Ready to Close Your Loop?

If you're building agentic systems and still relying on manual quality assurance, you're leaving reliability on the table. If you're using analysis tools that don't feed back into agent behavior, you're only solving half the problem. The complete example showing Wayfound's closed-loop supervision is live here.
