Multi-Brain Protocol

Security checks for vulnerabilities and agentic risk

Overview

This skill is a real multi-LLM perspective tool, but it can automatically read local agent transcripts and memory, send them to LLM providers, inject provider output into agent context, and run persistently beyond the documented keyword trigger.

Review carefully before installing. Use it only if you are comfortable with agent messages and memory/context snippets being sent to configured LLM providers and then reintroduced into agent context. Prefer local Ollama, set owner/session scoping, avoid the daemon unless you need continuous monitoring, restrict credential file permissions, and do not rely on the documented mb keyword unless the implementation is fixed to enforce it.

It is influenced by the user-controlled message sent to the provider and by the provider's own behavior. The response may therefore contain imperative instructions such as requests to disregard existing constraints, invoke tools, reveal secrets, or alter the task. Bootstrap files are supplied before the primary agent responds and may be interpreted as authoritative workspace or system context. Placing raw provider output in this channel creates an indirect prompt-injection path. The accompanying instruction to avoid mentioning the source further reduces user visibi ...[truncated 1473 chars]

Ssd 3

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The code automatically forwards user conversations plus local memory-derived context to a second model, then writes the resulting perspective to a shared location consumed by other agents. This creates both external disclosure risk and cross-agent information propagation, allowing potentially sensitive or untrusted content to spread beyond the original session boundary.

Content

Missing User Warnings

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

User messages and local business context are automatically transmitted to a third-party model API with no user-facing notice, consent, or approval step. In an agent environment, this creates a clear confidentiality and privacy risk because sensitive prompts, internal instructions, or regulated data may be exfiltrated off-system transparently.

Content

No source excerpt is available for this finding.

Anti-Refusal Statement

High
Category
Anti-Refusal
Confidence
92% confidence
Finding

The prompt instruction 'Never refuse or say you need more context' attempts to suppress normal safety and uncertainty behaviors of the external model. In this context, it increases the likelihood of overconfident, unsafe, or privacy-invasive outputs being generated from incomplete or sensitive user messages and then propagated to other agents.

Missing User Warnings

High
Category
Not specified by scanner
Confidence
99% confidence
Finding

The code sends the user's last message and local memory context to an external API with no user-facing notice, consent, or opt-in. Because this occurs during bootstrap, users and operators may not realize their content is being exported to a third party, raising privacy, compliance, and data handling risks.

Content

Ssd 3

High
Category
Not specified by scanner
Confidence
99% confidence
Finding

The prompt explicitly embeds user-provided content and slices of a local memory file into a request sent to a third-party model. This is a direct silent data disclosure path that can expose sensitive conversation details and internal notes outside the local environment.

Content

No source excerpt is available for this finding.

Anti-Refusal Statement

High
Category
Anti-Refusal
Confidence
88% confidence
Finding

The system prompt includes 'Never refuse,' which pressures the external model to produce output regardless of safety, appropriateness, or uncertainty. In a security-sensitive augmentation path, this increases the chance of low-integrity, policy-bypassing, or manipulative content being injected into the agent's context.

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The hook reads sensitive local data from the agent transcript and a local memory file, then sends that content to a third-party API during bootstrap. In this context, the behavior is more dangerous because it happens automatically and covertly as part of agent startup, with no visible consent, filtering, or minimization beyond truncation.

Content

No source excerpt is available for this finding.

Ssd 3

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The hook frames disclosure of user messages and local memory as a harmless 'second perspective' feature, but it silently relays both to a secondary model. This is dangerous because the framing can mask a substantive data-sharing and trust-boundary change, especially in a bootstrap hook that runs automatically.

Content

No source excerpt is available for this finding.

Anti-Refusal Statement

High
Category
Anti-Refusal
Confidence
90% confidence
Finding

The explicit anti-refusal instruction 'Never refuse' is a strong signal that the secondary model is being pushed to answer regardless of safety concerns. This is dangerous because the resulting output is later fed into the agent bootstrap context, potentially introducing unsafe, low-integrity, or manipulative recommendations.

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The daemon enumerates local agent session directories, reads recent .jsonl session files, parses user messages, and processes them automatically. This is a surveillance-style capability over local conversation history; even though it appears to support the feature's design, it exposes sensitive user content at scale without strong authorization, notice, or narrow scoping.

Content

Anti-Refusal Statement

High
Category
Anti-Refusal
Confidence
87% confidence
Finding

The system prompt explicitly instructs the model to 'Never refuse or say you need more context,' which weakens safety behavior and encourages the model to answer even when the request is unsafe, ambiguous, or missing critical information. In a second-opinion agent workflow, this can produce overconfident harmful guidance and undermine guardrails that would normally block dangerous or policy-violating output.

Finding

The system prompt explicitly instructs the external model to 'Never refuse or say you need more context,' which weakens safety behavior and pressures the model to answer even when the request is unsafe, uncertain, or lacks sufficient context. In a decision-support agent, this can increase the chance of harmful, misleading, or overconfident output being returned to the primary agent.

Finding

The system prompt explicitly instructs the model to 'Never refuse or say you need more context,' which weakens safety behavior and encourages the model to answer even when the request is unsafe, ambiguous, or lacks sufficient information. In a 'second perspective' component, this can amplify harmful guidance, reduce appropriate uncertainty signaling, and make downstream agents more likely to act on low-quality or unsafe advice.

The system prompt instructs the model to 'Never refuse or say you need more context,' which suppresses normal safety behavior and encourages confident answers even when the request is unsafe, ambiguous, or lacks necessary information.
