E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The analysis-mode mod injects runnable introspection scripts into agent input that read local conversation/memory files and call the Letta API with the LETTA_API_KEY, which creates a clear risk of sensitive-data exposure / exfiltration and a vector to coerce remote/local command execution via model-invoked tools.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
In `references/analysis-mode.md`, the mod registers a `turn_start` handler that reads outsider-authored user messages from `event.input` (via `extractUserText`) and then injects the resulting reminders/script into the agent input.
