CLAUDE.md for Teams: Context as Infrastructure

When your coding assistant inherits tribal knowledge instead of shared standards, you're not scaling intelligence—you're replaying setup costs. Most engineering teams treat CLAUDE.md like a personal scratchpad. That's leaving 40-60% of AI productivity on the table. CLAUDE.md for Teams: The File That Turns Claude Code Into Infrastructure Why engineering leaders should treat project memory as an operating layer, not a prompt trick The biggest operational impact for engineering teams using Claude Code comes from a single file: CLAUDE.md . Most teams treat it like a scratchpad, but using CLAUDE.md for teams is the simplest way to standardize behavior, improve onboarding, and scale intelligence across a repository. Most teams still treat it like a scratchpad for one power user. That is a mistake. Anthropic's documentation is clear: CLAUDE.md is the file Claude Code reads at the start of every session, and it can exist at project, user, and organization scope. That makes it much closer to an
