Overview
Period: 2026-04-03T20:07Z to 2026-04-04T19:18Z (since previous report §1646)
Runs analyzed: 4 of 4 Claude-engine runs (all had token data)
Total tokens: 317K across all workflows
Estimated total cost: $0.74
Only Secret Digger (Claude) ran Claude-engine workflows this period — no Security Guard or other Claude workflows ran. All 4 runs show consistent, efficient behavior with excellent cache performance.

🔍 Optimization Opportunities
-
ℹ️ Secret Digger — Cache write rate ~51% — Consistent with prior reports. Pattern is structurally sound: request 2 (sonnet) writes ~38K context tokens, request 3 immediately reads them back within the same run. The 37,927-token cache write is identical across all 4 runs (same system prompt size), confirming stability.
- Recommendation: No action needed. This is expected behavior for a 2-sonnet-turn workflow.
-
✅ I/O ratio improved — Avg I/O ratio dropped from ~45:1 (previous period) to ~23:1 this period, meaning the model is producing more output tokens relative to input. This is a healthy shift toward more generative responses.
-
✅ Haiku pre-classification is cheap — The first request per run uses Haiku (123 input, ~90 output tokens, no cache) for what appears to be a routing or classification step. Cost is negligible (<$0.001/run).

- Per-run token breakdown (all runs highly consistent):
- Input: ~127 tokens
- Output: 1,280–2,015 tokens
- Cache read: 37,927 tokens (from prior turn within same run)
- Cache write: 37,927–39,866 tokens
- Totals (4 runs): 508 input | 6,745 output | 151,708 cache_read | 158,048 cache_write
- Cache hit rate: 99.7% (stable, 4/4 runs)
- Cache write rate: ~51% (stable)
- Avg latency: 12,271ms/request
- Estimated cost: $0.18/run × 4 = $0.74 total
