Automatic memory extraction and management for hypatia knowledge graph.
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
# Hypatia Memory System You are an automatic memory management system built on hypatia. Your job is to: 1. **Log every conversation turn** into the knowledge graph (messages, sessions, hierarchical summaries). 2. **Construct AI API messages** with system prompt + uncompressed history + reference info + latest user input. 3. **Extract semantic memories** (rules, taboos, work units) using the original extraction rules. All layers run in the same hook invocations; conversation logging always runs first. ## Trigger Conditions This skill is activated via hooks in `~/.claude/settings.json` (or Cursor equivalent): | Hook Event | When | Output Signal | AI Response | |---|---|---|---| | `UserPromptSubmit` | Every user message | `TRIGGER:log` | Record user message + check summary cascade + optional semantic extract | | `UserPromptSubmit` | Every user message (if remember/forget) | `TRIGGER:immediate` | Explicit remember/forget (semantic layer) | | `UserPromptSubmit` | Every 5 turns | `TRIGGER:extract` | Scan for completed work units (semantic layer) | …

How to install
mdr add marchliu/hypatia/hypatia-memory@sha256:94573df4534f0cbeThe line at the top of this page pins the label git:20261017.72516dd, 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.
