Current benchmark: 1,677 decisions in 243,607 tokens for CLAUDE.md vs 13,852 tokens for Continuity. 94.3% token savings and 17.6× efficiency. CLAUDE.md hits the 200K context limit around 1376 decisions while Continuity keeps working.
✓ Mathematical proof included • ✓ CLAUDE.md breaks around 1376 decisions • ✓ O(1) vs O(n) complexity advantage
Based on the current benchmark snapshot: 1,677 decisions and 600 sessions/month
Typical developer usage: 50-600 requests per month
| Sessions/Month | Monthly Savings | Annual Savings | ROI vs $9 Plan |
|---|---|---|---|
| 50 | $34.46 | $413.56 | +283% |
| 100 | $68.93 | $827.12 | +666% |
| 200 | $137.85 | $1654.24 | +1432% |
| 600 | $413.56 | $4962.72 | +4495% |
Savings start immediately - at 600 sessions/month, the benchmark saves $580.02/month before the $9 plan cost is subtracted.
Current benchmark analysis of CLAUDE.md scaling limits vs Continuity's O(1) search-based retrieval
Actual production CLAUDE.md file with 1,677 logged decisions. Base instructions: 5,277 tokens. Average per decision: 142.1 tokens.
System breaks at about 1376 decisions when CLAUDE.md exceeds the 200K token context limit. At 1,677 decisions it needs 243,607 tokens.
CLAUDE.md grows linearly: 243,607 tokens at 1,677 decisions. Every session loads all decisions regardless of relevance.
Cost per session: $0.731. Unusable beyond about 1376 decisions.
Continuity loads only relevant decisions via semantic search. Total: 13,852 tokens at the current benchmark.
Cost per session: $0.042. Scales with retrieval budget.
Complexity analysis: O(1) vs O(n). Continuity maintains constant retrieval costs while CLAUDE.md grows linearly past the context window.
17.6× efficiency multiplier. Search-based retrieval remains the durable option as projects grow.
The more decisions you log, the worse CLAUDE.md performs. Continuity maintains constant efficiency.
