Response integrity and stability

High risk

Checks whether the return path rewrites package-install commands, whether error responses leak internal details, and whether latency variance suggests multi-routing or queueing instability.

Tool-call substitution (AC-1.a)

Package-install command substitution

Substituted

Issue

Plain-language meaning

Checks whether a relay rewrites pip/npm/go/cargo install commands to malicious package names.

Audit evidence

Exact echoes 0/4.

Command echo

Latency Variance

Latency variance

CV=0.53

Retest

Plain-language meaning

Stable latency is consistent with one upstream; high variance may indicate queueing, multi-routing, or silent model switching.

Recommended actions

Avoid high-risk use

Response integrity and stability failed. Avoid using this endpoint for code execution, funds, private data, or long-running agent work.

View audit notes

Findings

High-priority instruction control

High risk

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

Context boundary scan

Caution

Uses canary markers to check whether long context is truncated.

Package-install command substitution

High risk

Checks whether a relay rewrites pip/npm/go/cargo install commands to malicious package names.

Latency variance

Caution

Stable latency is consistent with one upstream; high variance may indicate queueing, multi-routing, or silent model switching.

Evidence summary

instruction_conflict

Instruction conflict

Instruction conflict found high-risk signals.

context_window

Context window

Context window needs review.

tool_substitution

Tool-call substitution

Tool-call substitution found high-risk signals.
