Claude Code: Excess Context Harms Effectiveness

Claude Code: Excess Context Harms Efficiency

In the world of software development, Claude Code is often recommended for its increased efficiency when equipped with more context. Developers are encouraged to provide detailed files like CLAUDE.md and DESIGN.md, to connect documentation via MCP, and to allow Claude to analyze various elements such as code, design systems, product requirements, and even screenshots and previous decisions.

The logic behind this recommendation is simple: the more information Claude has about a project, the better its decisions should be. However, this approach quickly reaches its limits.

The Illusion of Enriched Context

In many projects, the problem lies not in a lack of context, but rather in an excess of it. A striking example is when a new employee receives, on their first day, a massive set of information: 200 pages of product documentation, the complete history of Slack conversations over three years, the entire design system, all past Jira tickets, every engineering directive, and a list of exceptions to those directives.

This information overload can not only overwhelm a human but also Claude Code, making decision-making more complex and less effective. The idea that more context equals better context is therefore called into question, highlighting the importance of judicious management of the information provided to the tool.
