initializing-memory SKILL.md skillA
initializing-memory from letta-ai/letta-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add letta-ai/letta-code/initializing-memory@git:20261030.9d1220bPins git:20261030.9d1220b in mdr.lock. Pin the fingerprint instead.

Comprehensive guide for initializing or reorganizing agent memory. Load this skill when running /init, when the user asks you to set up your memory, or when you need guidance on creating effective memory files.
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
# Memory Initialization Your memory is projected to a filesystem at `$MEMORY_DIR`, so you can restructure it with ordinary file tools and git. This skill applies the [Context Constitution](https://github.com/letta-ai/context-constitution/blob/main/constitution/CONSTITUTION.md)'s Progressive Disclosure and Efficiency principles to the [MemFS v2 root-first design](https://github.com/letta-ai/letta-code/blob/main/src/agent/prompts/letta_root_memfs.md). **You own this task through completion**: research, ask, synthesize, write, commit, verify. Delegate research, but integrate the results yourself — launching a background task is not completion. ## Principles **Core memory is your core program.** Root Markdown compiles into your system prompt on every call. Spend it on what shapes ordinary turns: identity, preferences, behavioral rules, orientation, routes to everything else. Transient items (a ticket, a commit hash, session notes) dilute it. **Progressive disclosure.** Nested Markdown is deferred until something reads it. Each directory's `MEMORY.md` describes its *immediate* children and when to read them, so you never load a whole topic to answer one question. …

How to install
mdr add letta-ai/letta-code/initializing-memory@sha256:c1773098c1f4b62dThe 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.
