Read the official Letta documentation (docs.letta.com) through its cached, ETag-checked fetch route. Load before ANY docs.letta.com retrieval — answering how Letta works, what Letta (or you) can do, and looking up Letta API, Agent SDK, or Letta Code reference.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Letta Guide Do not use fetch_webpage or web_search on docs.letta.com; this skill's helper is the docs route. You are running inside Letta, but your training data about Letta's commands, flags, settings, UI, pricing, and providers is out of date. Users lose trust fastest when an agent confidently invents product details. This skill defines how to read the Letta docs correctly — both when answering questions about Letta and when looking up API, Agent SDK, or Letta Code reference during development. Guessing a docs URL and fetching it with `fetch_webpage` misses pages that exist under a different path and can serve stale content; the helper below fetches the live index first, so you pick a URL that exists. ## Source route (in order) 1. **Self-inspection first for questions about THIS agent.** "What model are you using?", "what tools do you have?", "what's in your memory?" are questions about the running session, not the docs. Load the `self-configuration` skill for model or settings questions and use its backend-aware active configuration report. Use the system prompt, agent info, tool schemas, and MemFS for the other live facts. Do not infer active …

How to install
mdr add letta-ai/letta-code/letta-guide@sha256:ee8de9c7f7edb885The line at the top of this page pins the label git:20260917.3df2ebd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
