Hey @DeboJolaosho , It’s really solid work on the valta-audit-chain implementation. You are absolutely right that moving the financial gate upstream of the provider payload is the only way to prevent runaway agent execution loops. The SHA-256 ledger for billing accountability is a nice touch.
While building pre-call financial guardrails, our enterprise teams realized that stopping an agent when it goes broke is necessary, but the bigger issue was why the agent was burning so many tokens in the first place.
Almost always, the agent gets stuck in a recursive failure loop because it was fed deprecated, contradictory, or stale RAG context (Context Rot).
To solve this upstream, we built KU-Gateway (a localhost FastAPI proxy). Instead of just tracking the budget, the gateway actively intercepts the payload, applies a deterministic temporal decay algorithm to the embedded , and strips out the rotting data before it hits the LLM.
By filtering the stale data upstream, the agent stops hallucinating, which stops the recursive tool-calling glitch you mentioned. As a byproduct, it structurally shrinks the prompt size, cutting the token burn by ~50% per call.
Your valta-audit-chain is perfect for hard financial limits. If anyone wants to look at the architecture for reducing the token payload before the limit is hit via context-filtering, our Python/FastAPI implementation is open-source here: GitHub - VLSiddarth/KU-Gateway · GitHub
Wrote a deeper technical breakdown on how the temporal decay math works at the proxy layer here: I built a localhost proxy that stops LangChain from hallucinating on dead RAG data (and cuts token burn by 50%) - DEV Community
Great discussion. The community desperately needs to move agent governance to the proxy layer.
