Logseq Brain

Persistent memory for Claude using a dedicated Logseq graph. Save and load project context, decisions, and progress across sessions and devices.

Overview

This plugin turns a Logseq graph into Claude's external brain. Claude can read from and write to the graph, storing project plans, decisions, implementation details, and session logs. Because Logseq syncs across devices, your Claude context travels with you — start a task on your desktop, continue on your notebook.

Install

Logseq Brain ships through the skillsmith marketplace.

Claude Code

/plugin marketplace add jame581/skillsmith
/plugin install logseq-brain@skillsmith

GitHub Copilot CLI

copilot plugin marketplace add jame581/skillsmith
copilot plugin install logseq-brain@skillsmith

Gemini CLI

gemini extensions install https://github.com/jame581/LogseqBrain

Cowork (Desktop App)

1. Create a new Logseq graph called "ClaudeBrain" (or any name you prefer).
2. Install this plugin in Claude (accept the .plugin file).
3. Say "init brain" — Claude will ask you to select the graph folder.
4. Say "init brain project MyProject" to add your first project.

Setup

After installing, create a Logseq graph (e.g. "ClaudeBrain") and tell the plugin where to find it. Pick one:

• Environment variable: export LOGSEQ_BRAIN_PATH=/path/to/ClaudeBrain (highest precedence)
• Just tell Claude the path when prompted — Claude saves it to a durable user config file (%APPDATA%\logseq-brain\config.json on Windows; on macOS/Linux $XDG_CONFIG_HOME/logseq-brain/config.json if XDG_CONFIG_HOME is set, otherwise ~/.config/logseq-brain/config.json) so you're not asked again, even after plugin reloads

Then say "init brain" to set up the graph structure, and "init brain project MyProject" to add your first project.

Skills

brain-init — Set up the graph for the first time, or add a new project.

• "init brain" — creates the graph structure (Index, Meta, Decisions pages)
• "init brain project MyProject" — adds a new project page

brain-load — Load project context into the current session.

• "load MyProject" — loads the project context (brief mode by default)
• "load MyProject full" — loads everything including decisions, implementation, linked tasks
• "load brain" — loads a high-level overview of all projects
• "what do we know about strategy pattern" — searches across the graph

brain-save — Save the current session's work to the graph.

• "save to brain" — saves decisions, progress, and plans from this session
• "save progress" — same as above
• "remember this" — save specific information
• Automatically detects multi-project sessions and Jira task context
• Updates Meta.md when new user preferences are discovered
• Jira comment drafts are stored verbatim in fenced code blocks, then verified with a mechanical post-write check over the files just written
• Seeds and updates task status:: as work progresses, and suggests Session Log rotation to a SessionArchive page once a project page grows past 64 KB / 40 entries
• Refreshes the project's Index.md one-liner on every save

brain-status — Quick dashboard of all projects.

• "brain status" — shows all projects with status, last activity, current focus
• "show projects" — same as above
• Flags stale projects that haven't been updated recently
• Groups task pages by status:: (active, blocked, done)

brain-doctor — Lint and repair the graph (graph hygiene).

• "brain doctor" / "check brain health" — scans for format problems and reports them
• "fix brain" / "clean up brain" — repairs them after a backup and your confirmation
• Catches the things that quietly create empty "phantom" pages or broken macros: code wrapped in {{ }}, bare #number/hex tags, un-namespaced [[Task]] links, [[file://]] links; also flags malformed properties, broken/duplicate entries, and structural gaps
• Reports unfenced Jira markup residue and guides a one-time batch backfill of missing task status::

Journey Log

Every brain operation (init / load / save / status / search) leaves a one-line HH:mm-prefixed bullet in today's journal under ## Activity — a low-cost, time-ordered audit trail of what Claude did, when. Disable by adding "journeyLog": false to your user config file (%APPDATA%\logseq-brain\config.json on Windows; on macOS/Linux $XDG_CONFIG_HOME/logseq-brain/config.json if XDG_CONFIG_HOME is set, otherwise ~/.config/logseq-brain/config.json).
