This is a real problem — I blew past $300 in a week before I even noticed. The lack of visibility is genuinely alarming when you're letting an agent run autonomously.
Few questions that'd help me understand the scope better:
The risk level tagging (read/write/exec) — is that purely for logging, or are you planning any threshold-based alerting? Like "pause and ask me before you rack up another $50 in exec calls"?
Also curious about the append-only guarantee. What's preventing a compromised agent from tampering with the ledger before your audit? Is that a threat model you've considered or intentionally out of scope?
The Cursor billing pull is clever — did cursor.com's API require any reverse engineering or is that documented somewhere?
Rust was the right call for something sitting in that critical path. Nice work shipping something you actually needed. This fills a gap that the agent tools themselves are weirdly uninterested in solving.
