Overview
Period: 2026-04-01T01:01Z to 2026-04-02T01:01Z (24 hours)
Runs analyzed: 5 Copilot-engine runs (3 had token data)
Total tokens: 642,938 across all instrumented workflows
Estimated total cost: $1.64
⚠️ This is the first token usage report. Historical trend data will be available in future reports.
All three instrumented workflows show 0% prompt cache hit rate — a systemic optimization gap. All traffic routes through the Copilot provider to claude-sonnet-4.6.

🔍 Optimization Opportunities
-
All workflows — 0% cache hit rate (systemic)
- No
cache_read_tokens or cache_write_tokens in any request across all 3 workflows
- Prompt caching is not enabled on the Copilot inference endpoint or the API proxy is not setting cache breakpoints
- Recommendation: Enable Anthropic prompt caching on the system prompt / static context. For Smoke Copilot with 40–44K input tokens per request, caching the static prefix could reduce input cost by ~90%, saving ~$0.90/run
-
Smoke Copilot — high cost ($1.09/run), very high I/O ratio (201:1)
- 10 requests with input tokens growing from 40K → 44K (accumulating conversation context without caching)
- 201:1 input/output ratio indicates large system prompt / tool schema relative to generated output
- Recommendation: Review MCP tool surface exposed to the agent — fewer tools means smaller context. Each request reprocesses 40K+ tokens from scratch.
-
All workflows — I/O ratios well above 10:1
- Secret Digger (Copilot): 179:1 (34–35K input, minimal output)
- Build Test Suite: 79:1 (34–38K input per request)
- These ratios suggest large static context (system prompts, tool schemas) being resent every request
- Recommendation: Identify and cache the static prefix in system prompts to reduce billable input tokens
Per-Workflow Details
Smoke Copilot
- Run: §23878258933 (scheduled,
main)
- Requests: 10 (all
claude-sonnet-4.6 via copilot provider)
- Tokens: 428K total — 426K input, 2K output, 0 cache_read, 0 cache_write
- Cache hit rate: 0%
- Avg latency: 3,992ms/request
- Estimated cost: $1.09
- Pattern: Input tokens grow steadily (40K → 44K) across 10 requests — conversation history accumulating without caching; output is small (24–354 tokens each)
