Agent Credential Guard
by Matt Busel
On a 401 your agent stops and reports instead of hunting for tokens. Protocol + a Claude Code hook that blocks secret reads.
AI Engineer @ Tensorust. I write the guardrails I use on my own coding agents: tamperproof (tests stay read-only, done means the real suite passes). Proof: 8 iOS apps live on the App Store, 524K views on X, 517 GitHub stars, O'BLOCK on Steam Oct 20. Questions: mattbusel@gmail.com

Several agents on one account? One shared request budget they all obey, and a 429 seen by one pauses all of them.

Build and prove the grader before the code, lock it, and keep only changes where more tests pass and none break.
