Real-world analysis of CLAUDE.md scaling limits vs Continuity's O(1) search-based retrieval
Actual production CLAUDE.md file with 795 logged decisions. Base instructions: 7,053 tokens. Average per decision: 286 tokens.
System breaks at 674 decisions when CLAUDE.md exceeds 200K token context limit.
CLAUDE.md grows linearly: 234,147 tokens at 795 decisions. Every session loads ALL decisions regardless of relevance.
Cost per session: $0.702 (Claude pricing). Unusable beyond 674 decisions.
Continuity loads only relevant decisions via semantic search. Total: 20,073 tokens at 795 decisions (91.4% savings).
Cost per session: $0.060. Scales indefinitely with constant token usage.
Complexity analysis: O(1) vs O(n). Continuity maintains constant 20K tokens while CLAUDE.md grows linearly.
11.7× efficiency multiplier. System breaks at 674 decisions. Full analysis in documentation.
The more decisions you log, the worse CLAUDE.md performs. Continuity maintains constant efficiency.
