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-code — Agent Guide

This file explains how to work effectively in this repo. It covers the rules enforced by CI, **why each rule exists**, and the workflow conventions that keep the codebase healthy and agent-navigable.

---

## Workflow

1. **Create a worktree** for any non-trivial change — especially if another agent may be working concurrently.
2. **Make your change**, then run `bun run check` and fix all failures before opening a PR.
3. **One PR per logical change.** Don't bundle unrelated changes — harder to revert if something breaks.
4. **Never amend commits.** Always create a new commit.
5. **Check the current branch** before editing files. If in doubt, ask.

---

## Runtime Validation

### Automated notifications use user-role reminders

Never inject `role: "system"` messages into conversation history for harness
notifications, recovery, teleport, onboarding, or mod instructions. Use
`role: "user"` with `<system-reminder>...</system-reminder>` content instead.
The tags identify automated context without requiring API-level system priority;
the existing transcript echo strips reminder-only content from user bubbles.

How to install

The exact contents, by fingerprint
mdr add letta-ai/letta-code/AGENTS.md@sha256:d682ab91f45d91dc

The line at the top of this page pins the label git:20261102.b2f54b8, 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.
