Engineering teams rarely fail because they lack skill

As teams grow and move faster, decisions are made quickly to ship features, fix bugs, or meet deadlines. Over time, the reasoning behind those decisions fades. Code remains, systems run, but the original intent disappears.

This is how engineering teams slowly lose clarity.

Where the problem begins

Most decisions live in places that were never designed to store long-term reasoning: Slack threads that get buried, pull request comments that are never revisited, meetings where conclusions are never written down, and verbal explanations passed from one engineer to another.

At the moment, everyone understands what is happening. Six months later, no one does.

Code survives, context doesn’t

Code is durable. It stays in repositories for years. Context is fragile. It disappears when people leave, priorities shift, or systems evolve.

When teams forget why something was built, they hesitate to refactor, reintroduce old bugs, rebuild systems that already existed, and repeat the same architectural debates. This creates long-term drag that compounds as the team scales.

Why documentation doesn’t fix this

Documentation requires discipline, constant updates, and manual effort. Most teams don’t have the time or incentive to keep it current.

Even when documentation exists, it often explains what a system does, not why it was designed that way. The real issue is not a lack of tools. It’s the absence of memory.

The real solution

Engineering teams need a way to preserve reasoning automatically, as work happens, without adding overhead. Context should be treated as infrastructure, not an afterthought.
