We Spent Months Teaching AI to Read Our Codebases. We Forgot to Teach It How to Remember. Every developer has had this session: You spend three hours pair-programming with Claude, Cursor, or Codex. Together, you untangle a gnarly race condition in ...

This release is about something I think AI coding tools are missing: a safe floor. For months, I kept seeing the same failure mode. You give an AI agent a refactoring task. It renames a function.-->Breaks 11 files.-->Ships the change. You spend...

This release is focused on one idea: Give AI coding agents better context, while reducing the amount of unnecessary context they need. When working across Claude Code, Cursor, Windsurf, Copilot, Cline, Antigravity, and other coding agents, a lot of...

Why Production Agents Are Ditching Pure RAG for Context Caching Three months ago, our agentic workflow hit a cost wall. We were running a multi-step research agent that performed iterative document analysis. Every user request triggered between 12 ...

After months of building, iterating, breaking things, and shipping, I’m excited to finally launch TokenCap on Product Hunt. TokenCap helps AI coding agents work with codebases more efficiently by generating graph-ranked, token-budgeted context so...

A couple of years ago, everyone was talking about Prompt Engineering. People experimented with prompts like: "Act as a senior software engineer." "Think step by step." "Explain like I'm five." And it worked. A better prompt often produced a be...

In Part 1https://coderlegion.com/21935/ai-fundamentals-part-1-from-prompt-to-response, we learned how an LLM turns your prompt into a response. It all comes down to predicting one token at a time using the information available in its context windo...

If you've been building AI applications recently, you've probably come across Retrieval-Augmented Generation RAG. It has become the go-to way of giving LLMs access to external knowledge. But RAG isn't the only option. As context windows continue to...

Most developers think of a folder tree as a way to organize files. For AI systems, it can be much more than that. The Interpret-able Context Methodology ICM, also known as the Model Workspace Protocol MWP, introduced by Jake Van Clief and David McD...

There's a moment in Ravi Kumar's keynote at the Cognizant AI Forum 2026 that cuts through a lot of the noise around enterprise AI. He puts it simply: a trillion dollars has already been invested in AI infrastructure. Another six to seven trillion is ...

Sanitization by Construction: Bounded Context Before the Network Regex redaction on arbitrary broker exports fails the moment a column renames, a locale shifts decimal separators, or a merged cell appears. We chose structural exclusion: the Ask AI ...

I caught myself, again, telling Claude that we don’t do it that way in this codebase. Not the first time that week. Not the first time that day. Different repo, same correction. The kind of correction that doesn’t belong in a CLAUDE.md because it’...

The agent is not the problem. The substrate around the agent is. Here is the four-file shape that made my Convex production-database write boring on 2026-05-06, plus a stdlib Python script the Claude Code agent calls but did not generate. Before the...

You open a new Copilot chat and explain everything again. Your stack. Folder structure. That “no default exports” rule. Copilot writes code, but forgets context. This isn’t a bug though. LLMs are stateless, every chat starts fresh. The good part?...
