AI Tools: Use Context Files (.cursorrules, AGENTS.md, CLAUDE.md) Without Bloat
Context files punch above their weight when concise; bloated rules files train AI tools to ignore them and slow every call down.
8 min · Reviewed 2026
The premise
Project context files are powerful because every prompt sees them; that same property makes long ones expensive and easy to ignore when they contradict the diff in front of the model.
What AI does well here
Keep rules under 200 lines
Lead with non-negotiables (security, conventions)
Cite paths to deeper docs rather than inlining
Review and prune quarterly
What AI cannot do
Force the model to follow rules — only encourage
Replace lint and CI for hard requirements
Substitute for code review
