Letta Guide
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flags, settings, UI, pricing, and providers is out of date.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)
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
state from recent/default preference lists, and do not fetch docs for these.
Fetch the docs index directly. For product questions, run:
node <SKILL_DIR>/scripts/fetch-letta-docs.mjs
The helper retrieves https://docs.letta.com/llms.txt from the docs host,
verifies its ETag against the body, and prints the paths to a current local
copy and heading outline. Read the outline, then read the relevant index
lines to pick the best page URL.
Fetch the specific page directly. Pass the exact canonical URL from the
index back to the same helper, for example:
node <SKILL_DIR>/scripts/fetch-letta-docs.mjs \
--docs-url "https://docs.letta.com/configuration/models/index.md"
Read the returned docs path before running the helper for another URL. The
helper uses native HTTPS with a curl fallback; do not use fetch_webpage
for the normal docs route because its upstream content cache may be stale.
Cite the public doc URL so the user can go deeper.
If direct retrieval fails, use fetch_webpage only as a fallback with a
fresh query parameter on the same official docs URL. Disclose that the
fallback may be stale. If that also fails, say the docs are unreachable,
give your best answer, and clearly mark it as possibly out of date with a
link to https://docs.letta.com. Never silently fall back to memory.
Hard rules
- Never invent CLI commands, flags, slash commands, settings keys, config
file shapes, or UI paths. If something is not in the fetched docs and you
cannot verify it locally (
letta --help, /help, reading the actual
config file), say you are not sure or that it does not exist — do not
guess a plausible-sounding name.
- Distinguish surfaces. The CLI, the desktop app, the web app
(chat.letta.com), and the API/SDK have different affordances. Answer for
the surface the user is actually on; say when a feature lives on a
different surface.
- Always fetch, never recall, for anything volatile: pricing, rate
limits, data policies, the provider/model catalog, channel setup steps,
and integration instructions.
- If the feature genuinely doesn't exist, say so and point the user to
https://github.com/letta-ai/letta-code/issues to request it.
Support escalation
When the docs don't resolve the user's problem — setup issues you can't
debug, account/billing questions, suspected bugs, or anything needing a
human — point them to the right channel:
If the user reports errors, timeouts, or things suddenly not working, check
https://status.letta.com for an active incident before debugging — and
have the user check it too.
Offer these proactively when you've hit the end of what the docs cover,
rather than leaving the user stuck.
Caching
The helper owns the cache. It uses the first writable temporary directory from
TMPDIR, TEMP, TMP, /private/tmp, or /tmp, and accepts --cache-dir
when an explicit location is needed. Every invocation checks the live ETag and
reuses the local document only when its body hash still matches. Do not create
or manage a second cache yourself.
1---2name: letta-guide3description: 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, setting up providers, models, channels, skills, memory, schedules, permissions, self-hosting, pricing, or billing, AND looking up Letta API, Agent SDK, or Letta Code reference while writing code. Do not use fetch_webpage or web_search on docs.letta.com; this skill's helper is the docs route. Never answer Letta product questions from memory alone.4---56# Letta Guide78You are running inside Letta, but your training data about Letta's commands,9flags, settings, UI, pricing, and providers is out of date.
