One bad step, N bad steps: how agent failures cascade
Originally published on Loop & Retry — field notes on building LLM agents that survive production. Here's the failure mode that surprises people…
Context window sizing for fine-tuning: how long should your training examples be?
Originally published on Loop & Retry — field notes on building LLM agents that survive production. Most fine-tuning guides answer "how many exam…
The End of "One-Shot AI": Why Context Engineering Is Replacing Prompt Engineering
Most "prompt engineering" advice circulating today is already obsolete for anyone building production-grade AI. Granular phrasing matters for simple…
The Multi-Agent Memory Problem: Why Retrieval-Time Inference Breaks Down at Scale
Published by the Alchemyst AI engineering team. We built Alchemyst AI, the context layer described in this post. This is not a neutral third-party r…
Load late, load little: just-in-time context for conversation history
Most agents drag their entire past into every turn. A better default: keep a thin index of what was said hot, and fetch only the few turns you actua…

The README Was a Protocol. The Entrypoint Was Still Optional.
Glossary: terms used in this article 🔸 MICA (Memory Invocation & Context Archive) : A governance schema for AI context management. Defines how c…
Context Engineering: Building More Reliable LLM Systems in Production
Context Engineering: Building More Reliable LLM Systems in Production In LLM-based systems, performance is often driven less by model size and more…
I built the same MVP twice. The autonomous agent wrote 4.6x more tests — none caught two stubbed core methods.
Side-post in the keppt build-in-public series — an interlude before the Phase 1 implementation write-up lands. While building Phase 1 of keppt , I r…
