Featured Story

Your Codebase Has Context Your Repo Doesn't Store. Here's Where It Goes.

Most code work slows down before the first edit. The problem is usually not writing the change. It is finding the right code, understanding what depends on it, recovering prior decisions, and keeping follow-up from getting lost. This guide shows how to use ContextStream as a practical layer around a real repo so code work becomes easier to understand, safer to change, and easier to continue later.

Where Things Go in ContextStream: Memory vs Docs vs Todos vs Plans

New users usually hit the same question quickly: where should this go? If that stays fuzzy, the system gets messy fast. This post gives you the working model for deciding what belongs in memory, what should become a doc, what should be tracked as a todo, and when something is really a plan.

What ContextStream Is and Why it Matters

AI tools are good at helping in the moment. They are much worse at preserving the state around the work once that moment ends. This post explains what ContextStream is, what problem it actually solves, and why it matters if you want AI-assisted work to accumulate instead of disappearing into chat history.

The Missing Layer in Every Multi-Agent Architecture

Most multi-agent designs split work by role. The smarter approach splits by context boundaries. But both assume agents have no memory. Add a shared context layer and the entire calculus changes — you can design by expertise again, and sub-agents stop being a band-aid for context window limits.

A New Study Says Delete Your CLAUDE.md / AGENTS.md. Here's What Actually Works Instead

A recent paper just measured what CLAUDE.md and AGENTS.md files actually do to coding agents. The results are bad. Developer-written context files improved task success by about 4% on average, while LLM-generated context files *decreased* success by roughly 3% and both increased cost and latency by over 20%. And this isn't a fringe result it matches what most developers already suspect.
