You have three memory systems. They don't talk to each other. Brain Sync fixes that — extracts triggers and relations for your fast-twitch Memory MCP, keeps deep docs in your Obsidian brain. TRUST 5 quality gate on every sync.
Brain Sync keeps your three-layer AI memory stack in sync without duplication. It reads your Obsidian knowledge base, extracts the "how to use" information (triggers, relations, orchestras), and stores it in Memory MCP for 0.1-second reflexes. Full documentation stays in Obsidian for deep reasoning.
你有三个记忆系统。它们互相不说话。 Brain Sync 修复这个问题——提取触发词和关系到 快反应小脑，把深度文档留在大脑。每次同步都过 TRUST 5 质量门。
| Feature | What it does |
|---|---|
| 🔍 Drift Detection | Compares Obsidian skill count vs Memory MCP entity count |
| ➕ Auto-sync Missing | Creates entities for skills not yet in Memory MCP |
| 🔗 Auto-relations | Links every new tool to its orchestra |
| 👻 Ghost Pruning | Removes entities that no longer exist in Obsidian |
| ✅ TRUST 5 Quality Gate | Tested · Readable · Unified · Secure · Trackable |
| 📊 Sync Report | Before/after table with pass/fail for each dimension |
| 🎚️ Progressive Disclosure | L1 150-token summary → L2 4000-token full spec |

Every sync passes through five automated checks. If any fail, the report tells you exactly what to fix.
| Dimension | Check | Failure means |
|---|---|---|
| T Tested | Can search_nodes find the new entity? |
Write failed — entity not persisted |
| R Readable | Observations ≤ 3 each, ≤ 200 chars each | Small brain overloaded — trim it |
| U Unified | Obsidian count ≈ Memory MCP count? | Brains drifted — gap > 2 warns, > 5 fails |
| S Secure | No ghp_ / sk- / token leaks in observations? |
Immediate fix — expose credential |
| T Trackable | Sync report output? | No audit trail |
tool-eval → Evaluate someone else's tool (should I install this?)
preflight → Check your own project (is this ready to ship?)
brain-sync → Sync small brain and big brain (memory consistent?)
All three belong to Orchestra ⑮ AI/ML — your skill development toolchain.
