What io.github.EDKarlsson/locus does

Hierarchical markdown-based memory system for autonomous AI agents. Each directory is a room (locus) in the palace, containing specific knowledge navigated on demand. Named for the atomic unit of the Method of Loci.

Locus

Core idea: Keep context windows small. Load only the room you need, not the whole palace.

How it works

palace/
  INDEX.md                    ← always read first (~50 lines max)
  global/
    toolchain/
      toolchain.md            ← canonical facts about tools
  projects/
    my-project/
      my-project.md           ← room overview + key files
      technical-gotchas.md    ← specialty: issues & resolutions
      sessions/
        2026-03-02.md         ← append-only session log

An agent reads INDEX.md, navigates to the relevant room, and reads only that room. Session logs accumulate until consolidation merges them into canonical files.

See the wiki for full documentation.

Quick start

# Install
pip install locus-mcp
# or: uvx locus-mcp --palace ~/.locus  (no install needed)

# Create a palace from the example template
cp -r example-palace ~/.locus
# Edit ~/.locus/INDEX.md to describe your palace

# Run the MCP server
locus-mcp --palace ~/.locus
# or: LOCUS_PALACE=~/.locus locus-mcp

Installation

MCP server (recommended for MCP-capable clients)

pip install locus-mcp

Or run without installing using uvx:

uvx locus-mcp --palace ~/.locus

Claude Code skills

Install all skills at once using the Makefile:

git clone https://github.com/Nano-Nimbus/locus.git
cd locus
make install-skills

Or install individually:

cp -r skills/claude/locus ~/.claude/skills/locus
cp -r skills/claude/locus-consolidate ~/.claude/skills/locus-consolidate
cp -r skills/claude/locus-audit ~/.claude/skills/locus-audit

cp -r skills/claude/locus-security ~/.claude/skills/locus-security
cp -r skills/claude/locus-palace-init ~/.claude/skills/locus-palace-init

Available Claude Code skills:

Skill	Command	Description
`locus`	`/locus`	Navigate the palace, read rooms, write session logs
`locus-consolidate`	`/locus-consolidate`	Merge session logs into canonical files
`locus-audit`	`/locus-audit`	Audit palace health
`locus-feedback`	`/locus-feedback`	Record explicit feedback on a palace recall
`locus-release`	`/locus-release`	Post-release verification workflow
`locus-security`	`/locus-security`	Security conventions for signed palaces
`locus-palace-init`	`/locus-palace-init`	Bootstrap a palace from existing memory files
