You face the South, Huitztlampa, land of thorns and flowers. Huitzilopochtli watches over what grows. The scene takes on turquoise tones of Xiuhtecuhtli mosaic.
You enter the noon. Here, what burns leaves a mark.
Synapse
A continuous AI memory across three machines.
The lived problem
In 2026, I use Claude Code daily on three machines: my personal setup at home, the one on mission at LR Technologies, a backup laptop. Each machine manages its own memory (user preferences, project context, validated feedback). Result: I repeat the same explanations to Claude on each machine, or worse, I manually copy memory files between machines with conflict risks. The "multiple assistants that don't know each other" pattern quickly becomes counterproductive.
Architecture chosen
Synapse is a plugin that bootstraps a Git-versioned memory structure, with automatic background sync on every significant change. Memory is typed: feedback (learned work rules), project (active project context), user (user profile), reference (pointers to external sources). Each entry has explicit YAML frontmatter, a short description, a type. A `[[name]]` linking system weaves entries together like a mini knowledge graph.
Technical choices
Node.js + TypeScript for cross-platform. Native Claude Code hooks (SessionStart, SessionEnd, UserPromptSubmit) to intercept key moments without monkey-patching. Background Git sync via non-blocking `child_process`. Smart local cache to avoid unnecessary network round-trips. Sync collision detection: two machines write at the same time, Synapse attempts automatic per-entry merge, alerts the user on conflict.
Quality as obligation
283 tests from the first public release, green CI, coverage > 80%. Why this rigor for a personal plugin? Because memory is precious · a bug that silently overwrites an entry is context lost that I won't recover. TDD here isn't dogma but a guarantee that memory doesn't corrupt itself.
Community opening
Published open-source from the first commit on github.com/smaurier/claude-synapse. Careful documentation, concrete examples, ADR (Architecture Decision Records) to trace choices. Ambition: that other multi-machine Claude Code users can bootstrap their own system. No business model, no premium · a tool solving a real problem for those who have it.
A song for this direction
Yn quetzalizquixochitl aya
oitzmolinico
mimilihui, cueponih,
in tepilhuan in quauhtli ocelotl
yxquich oncuetlahui ya
quexquich onquiçaquiuh huiya
quexquich onmomanaquiuh in tlalticpac
The precious izquixochitl
has come to green again,
it sprouts, it opens:
these are the princes, the eagle, the jaguar.
Everything withers,
all that comes to appear,
all that comes to be on the earth.
