syncing-memory-filesystem from letta-ai/letta-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add letta-ai/letta-code/syncing-memory-filesystem@git:20261030.9d1220b

Diagnose and repair MemFS repository setup, remote sync, authentication failures, optional backup remotes, or merge/rebase conflicts. Do not load for routine memory reads or edits.

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

# MemFS Repository Repair

Use this skill when the Git repository behind an agent's memory is not setting up or syncing correctly. Before editing memory, load the relevant skills: `maintaining-core-memory` for root/core files, `maintaining-deferred-memory` for deferred files, and `creating-skills` for skills. Then make the edit directly with ordinary file tools so the agent with the context applies the memory guidance. Stage only changed files by explicit path and commit in the same shell call, using the commit format in their *Commit memory changes* section. Verify the repair before reporting success. While the harness reports a repair in progress, leave memory files and Git state to that repair worker, which edits `$MEMORY_DIR` in place.

## Current Model

MemFS is a Git repository projected onto the computer where the agent is
running. `$MEMORY_DIR` is the repository root. There is no second `memory/`
directory inside it.

The repository can use either memory layout. Inspect its current tree and the
memory rules in the system prompt before editing files:

```text
Root layout                         Existing layout
$MEMORY_DIR/                        $MEMORY_DIR/
…

How to install

The exact contents, by fingerprint
mdr add letta-ai/letta-code/syncing-memory-filesystem@sha256:c16151f5f826b9e9

The line at the top of this page pins the label git:20261030.9d1220b, 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.
