letta-guide
Answer questions about Letta itself from the official documentation. Use whenever the user asks how Letta works, what Letta (or you) can do, or how to set up or configure providers, models, channels, skills, memory, schedules, permissions, self-hosting, pricing, or billing — any "how do I…" or "can Letta…" question about the Letta product. Fetch the docs before answering; never answer Letta product questions from memory alone.

2 low severity findings. 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
SKILL.md:17-38/ scripts/fetch-letta-docs.mjs:306-361 fetches outsider-authored free text from public web pages on `https://docs.letta.com/...` at runtime, then the agent reads the returned local docs/outlines (prose ingested into the LLM context indirectly via “Read the outline, then read the relevant index lines”).
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill's runtime helper (scripts/fetch-letta-docs.mjs) fetches external documentation from https://docs.letta.com/llms.txt (and allows fetching specific pages such as https://docs.letta.com/configuration/models/index.md) and the fetched markdown is read and injected into the agent's decision/response flow, so external content directly controls agent prompts.
