Claude Code plugin · self-compounding memory
Knowledge doesn't sit. It compounds.
Cortex is a personal memory layer for Claude Code. Every session automatically records commits, findings, and decisions, which can later be distilled into refined notes and retrieved with mixed-language semantic search. The vault is plain markdown + git as the source of truth; the vector store is just a rebuildable derived index. Built for anyone who wants working memory to compound across sessions instead of resetting every time.
Notes don't wait to be asked.
They rewrite themselves.
When a session surfaces something that touches an existing page, broadcast fuses it in place — new sections, corrected assumptions, sharpened caveats. The vault edits itself the way a wiki does, not the way a folder does.
Ask, don't dig
Hybrid retrieval (BM25 + vector) — mixed-language queries hit the right passage directly, without you remembering which file it's in.
Your vault is a living graph,
not a filing cabinet.
Cortex writes straight into Obsidian vault format — this is the shape wikilinks actually grow into. Try dragging a node.
Skills that trigger themselves
When the user wants to search the vault ("查 cortex", "之前有記過"), or when the request names a topic the SessionStart hook listed for this vault.
After a Raw has been distilled, to fuse it into related existing pages ("broadcast", "compound this into the vault"), or auto-dispatched at the end of the distill flow.
When the user wants to distill Raw session records into Notes/Projects ("提煉", "整理 raw", "distill").
When the user wants to save knowledge to the vault ("存到 cortex", "記一下"), or when the session-suggest hook recommends saving.
When context is running low and work needs to hand off to a later session ("交接", "takeoff", "交棒"). Produces temporary hand-off batons — one per work line — that are never committed or indexed. When the user refers to earlier work ("上次的", "之前那個", "we discussed"), asks to resume a previous session, or names a topic the SessionStart hook listed — routes the request to cortex-query. Stays out of the way otherwise.
