Navigates archived ChatGPT or Claude-style conversation exports and a MemFS reference archive on demand. Use when recalling what a past assistant knew, searching old conversations, rendering specific chats, seeding reference memory from export sidecars, or mining historical context without doing a full import.
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
# Navigating Chat History Without Digesting Everything Use this skill when the goal is **referenceable history**, not immediate full ingestion. ## Good fits - search my exported ChatGPT history for a topic - figure out what the old assistant knew about me - render the conversation where we discussed X - keep this export around as external memory and only mine it when needed - seed MemFS from `memories.json` or `projects.json` ## Default posture Treat the export as an archive you can navigate later. 1. read the MemFS archive index first if it exists: `reference/chatgpt/index.md` 2. inspect the export with `scripts/inspect-export.py` 3. search or list before rendering broad ranges 4. preserve findings to `reference/chatgpt/` first 5. promote to `system/human.md` only when the fact is durable, current, and worth carrying every turn Do **not** re-digest the entire archive unless the user explicitly wants that. ## Archive layout in MemFS Keep the external-memory archive under `reference/chatgpt/`. Recommended files: - `reference/chatgpt/index.md` — source exports, schema notes, known paths, retrieval strategy …

How to install
mdr add letta-ai/skills/navigating-chatgpt-history@sha256:ecc0015523668090The line at the top of this page pins the label git:20260521.b7217b9, 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.
