Tool
Prefix Cache Auditor
Client-side v0 for diagnosing cacheability score, unstable prefix segments, dynamic fields, schema volatility and cache-aware recommendations.
Prompt and request shape
No external calls. This only inspects text structure locally.
Cacheability score
Estimated risk based on unstable prefix shape, dynamic fields and schema volatility.
71/ 100
Unstable prefix segments
No obvious issue detected.
Dynamic field warnings
- trace_id
- timestamp
Tool schema volatility
- Tool schema includes volatile field: trace_id
Recommendations
- Keep tool schemas stable and avoid embedding trace/session/request fields in the cached prefix.
- Normalize dynamic fields into late request payloads instead of early system instructions.
- Make the first tokens of similar requests identical so provider prefix caches can match them.
Agent-step diff
- prefix_hash changes between agent steps.
- tools_hash changes between agent steps.
- Trace includes timestamp/request_id/trace_id: verify they are not in the prompt prefix.
