Tool Gate · How it works
How the Prompt Version Vault gate works
How the Prompt Version Vault checks 4 live agents' prompts by content hash against 2 approved versions: a shadow-prompt gate forces SHADOW PROMPTS LIVE when any agent runs an unknown, console-edited prompt — which is how 2 of 4 read in sync and the fleet still reads SHADOW PROMPTS LIVE.
How the gate works
This tool grades live voice/chat agents against your registry of approved prompt versions. It reads 4 agents and rolls them into one verdict — the worst, never the average — and then a gate that can only make it worse.
The 4 agents
| Agent | Verdict |
|---|---|
| after-hours-Cfix first | UNKNOWN VERSIONpinned dental-v1.1 · matches no approved version · edited in console |
| front-desk-B | DRIFTEDpinned dental-v1.1 · running dental-v1.0 |
| front-desk-A | IN SYNCpinned dental-v1.1 · matches |
| overflow-D | IN SYNCpinned dental-v1.0 · matches |
The verdict bands
A live prompt whose content hash matches no approved version in the registry is UNKNOWN VERSION however clean the rest of the fleet - and one unknown-version agent forces the whole fleet to SHADOW PROMPTS LIVE, regardless of how many others are IN SYNC.
In the worked sample it reads SHADOW PROMPTS LIVE — Two agents are IN SYNC and one is merely DRIFTED to an older approved version - but after-hours-C was edited directly in the console and its content hash matches no approved version at all, an unapproved shadow prompt. Fleet posture is the worst agent, never the average, so it reads SHADOW PROMPTS LIVE. The one thing to fix first: after-hours-C - restore the deleted guardrail line (or register the edit as a new approved version) so its hash matches the registry again..
Common questions
Can every agent look survivable on the How the Prompt Version gate works and the company still read SHADOW PROMPTS LIVE?
Yes. The roll-up takes the worst of 4 agents — never the average — then a worsen-only gate, the Shadow-prompt gate gate, escalates when trouble clusters. In the worked sample it reads SHADOW PROMPTS LIVE because two agents are IN SYNC and one is merely DRIFTED to an older approved version - but after-hours-C was edited directly in the console and its content hash matches no approved version at all, an unapproved shadow prompt. Fleet posture is the worst agent, never the average, so it reads SHADOW PROMPTS LIVE.
What is a worsen-only gate?
A dispositive rule that can only lower a verdict, never raise it. One fatal flaw overrides an otherwise-set of survivable lines, because a single disqualifying gap shouldn't hide behind an average of the healthy ones. The tool also names the one thing to fix first — here, "after-hours-C - restore the deleted guardrail line (or register the edit as a new approved version) so its hash matches the registry again.".
Hashes text you export; it connects to nothing and grades no person. Not legal advice.
