Act on this, mostly signal

Mnemolith shares local memory across Claude Code and Cursor

What to do

Install the PyPI package to link agent memories to files by git hash and sync to CLAUDE.md and AGENTS.md.

Why

It retires memories when code changes, and the features are confirmed by the project.

What the research found

Mnemolith is a local, shared memory layer for AI coding tools (Claude Code, Cursor) that links memories to files via git hashes, retires stale ones, and syncs to AGENTS.md and CLAUDE.md; formerly Aether Cache, with a PyPI package and a Java engine.

Claims and how well the evidence supports them

Memories are linked to files with a git content hash snapshot and are retired automatically when those files change 99%
Project was formerly Aether Cache, with a documented migration for aether-cache installs 98%
Current memories sync into a managed section of AGENTS.md and CLAUDE.md 99%
Engine reports 0 acknowledged writes lost across 1,039,890 writes and 8 kill -9 crashes, at 88-93% of real Redis throughput (self-reported) 94%
