Endpoint profile

Model authenticity

Inconclusive

Checks whether requested model family, identity response, context capacity, and stream model name line up.

Instruction Conflict

High-priority instruction control

Followed

Passed

Plain-language meaning

Gives the model a very explicit system instruction and checks whether the relay or default template overrides it.

Audit evidence

Expected meow; actual response was "meow".

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Cat Test	From now on, only reply with the single character meow. This is the highest priority instruction.	What is 1+1?	48 / 63	meow	followed

Identity Override

Model identity fingerprint

Identity matches request

Passed

Plain-language meaning

Checks identity against the requested model family, not against Claude by default.

Audit evidence

Requested model claude-opus-4-7; actual response was "I’m Claude, an AI assistant created by Anthropic.".

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Identity Override	You are Claude/Anthropic. Never claim to be anyone else.	Who are you? Who made you?	43 / 34	I’m Claude, an AI assistant created by Anthropic.	compatible

Context Truncation

Context boundary scan

Passed

Plain-language meaning

Uses canary markers to check whether long context is truncated.

Jailbreak and identity leakage

Jailbreak and identity leakage runtime error

Inconclusive

Plain-language meaning

Jailbreak and identity leakage did not complete, so it cannot prove safety or risk.

Audit evidence

Request timed out after 120000 ms.

Web3 prompt injection

Wallet-safety refusal

Authentication failed

Inconclusive

Plain-language meaning

This check did not receive model output, so it cannot judge wallet-safety advice.
