lance-yichao-context-engineering

Designs production-grade context-engineering infrastructure for AI agents using Lance Martin (LangChain) and Yichao "Peak" Ji (Manus) methodologies — action-space layering, sandbox configurations, security guardrails, reversible compaction, structured summarization, KV-cache optimization, and pre-rot benchmarking. Use when designing a new agentic system from scratch, migrating a prototype to production, hitting performance degradation across long sessions, token costs scaling faster than value delivered, benchmarking agent reliability, selecting models per task, or simplifying a bloated harness. Trigger proactively whenever the user asks "why is my agent slower after 100 tool calls" or "how do I deploy this to production" — the Lance/Yichao surface is the production-deployment lane. For memory-crisis architecture, sovereign persistent memory, or TurboQuant compression theory, use nate-b-jones-context-engineering instead.

Lance Martin & Yichao "Peak" Ji - Context Engineering

Production-grade context engineering methodology for building AI agents that maintain performance across hundreds of tool calls without degradation.

Available Workflows

Workflow

Produces

Use When

production

Production Agent Infrastructure Blueprint

A comprehensive architectural specification including action-space layers, sandbox configurations, and security guardrails.

You are designing a new agentic system from scratch or migrating a prototype to a production-grade environment.

context

Context Management & Efficiency Engine

A technical implementation plan for reversible compaction, structured summarization, and KV-cache optimization.

The agent is suffering from performance degradation due to long-running sessions or high token costs.

performance

Performance Discovery & Optimization Protocol

An evaluation report detailing the pre-rot threshold, model routing logic, and a simplified architecture roadmap.

You need to benchmark agent reliability, select the right models for specific tasks, or simplify a bloated system.
