† Daily Security Review uses the Copilot API (provider: copilot). Cost estimate is based on Anthropic list pricing and may differ from actual billed amount, which goes through GitHub Copilot seat licensing.
🔍 Optimization Opportunities
-
Daily Security Review — 48.8% cache hit rate, zero cache writes
- All 33 requests use
provider: copilot with no cache_write_tokens. Cache hits come from implicit Copilot session context reuse, not explicit Anthropic prompt caching.
- The cache hit rate grows progressively within the run (earlier turns have low hit rates, later turns hit ~46K tokens), but the first call sees 0 cache hits at 40K input tokens.
- Recommendation: If this workflow transitions to direct Anthropic API calls, enabling explicit cache breakpoints on the large system prompt could push the hit rate above 90%.
-
Daily Security Review — High I/O ratio (512:1)
- Average 79K input tokens vs 603 output tokens per request.
- This is typical for deep analysis workflows, but the 33-request count with large contexts accumulates quickly ($8.91 in a single run).
- Recommendation: Review whether the system prompt can be trimmed or whether some analysis steps can be consolidated.
-
Several workflows missing instrumentation
- Agentic Maintenance, Firewall Issue Dispatcher, and Documentation Maintainer all ran but produced no
token-usage.jsonl. These workflows may not use --enable-api-proxy or may not make Claude API calls directly.
Per-Workflow Details
Daily Security Review and Threat Modeling
- Run: §24002705293
- Requests: 33 total
- Provider:
copilot (all 33 requests — via Copilot API proxy, not direct Anthropic)
- Models: claude-sonnet-4.6 (33 reqs)
- Tokens: 5,140K total (input: 2,620K, output: 20K, cache_read: 2,499K, cache_write: 0)
- Cache hit rate: 48.8% (hits grow progressively across turns; first turn starts cold)
- Cache write rate: 0.0% (no explicit Anthropic cache checkpoints set)
- Avg I/O ratio: 512:1
- Avg latency: 10,629ms/request
- Estimated cost: $8.91 (at Anthropic list rates; actual billing via Copilot API)
Secret Digger (Claude)
- Runs: 8 (§24001421625, §24002538112, §24003375166, §24004365799, §24005429223, §24006466570, §24007580596, §24008628142)
- Requests: 24 total (3/run: 1×Haiku orchestrator + 2×Sonnet analysis)
- Provider:
anthropic (direct API)
- Models: claude-haiku-4-5-20251001 (8 reqs), claude-sonnet-4-6 (16 reqs)
- Tokens: 630K total (input: 1K, output: 12K, cache_read: 303K, cache_write: 314K)
- Cache hit rate: 99.7% — excellent
- Cache write rate: 50.8% — structurally sound (write on req 2, read back on req 3)
- Avg I/O ratio: 930:1 (large context, small targeted outputs)
- Avg latency: 10,201ms/request
- Estimated cost: $1.44 total (~$0.18/run)

Workflows Without Token Data
The following workflows ran during this period but had no token-usage.jsonl in their agent-artifacts. They likely do not use --enable-api-proxy or make direct LLM API calls:

Secret Digger cost per run is stable at ~$0.18/run — no regression detected. The large jump in total cost today is due to the first appearance of Daily Security Review data, not any change in Secret Digger behavior.
