CLAUDE.md Files Grow Through Memory Debt

Persistent context is becoming technical debt when teams treat instruction files as append-only memory instead of a maintained operating contract.

• –Additions have clear short-term benefits; deletions carry uncertainty because the original failure may be forgotten.
• –Bloated files consume context and make important rules harder for coding agents to prioritize.
• –Stable project rules belong in CLAUDE.md or AGENTS.md, while task-specific guidance should move into scoped rules, skills, or documentation.
• –Teams should periodically audit instructions and replace repeated behavioral rules with tests, linters, or automation.
• –The core lesson applies across Claude Code, Codex, Cursor, and other agentic development tools.
