# Sigillion, for an agent reading this repository

- Sigillion is lossless, local, provable memory for AI agents, made by Steddy Nova SRL. Today it ships as a Claude Code

- plugin: it keeps every Claude Code session on the user's own computer, word for word, compressed and sealed in

- hash-chained segments so that a change shows, after compaction and after Claude Code deletes its transcripts. Each new

- session starts with a brief of where the work stands, and Claude recalls earlier turns through MCP tools (recall,

expand, timeline, fixes, history), each answer with a receipt of what was read. Sigillion itself sends nothing

- anywhere: no telemetry, no account, the licence checked offline. What it hands Claude (the brief, the recalled

- turns) becomes part of the Claude Code session, which Claude Code sends to Anthropic as it does the rest.

The code is not here. The packages are on PyPI: `sigillion` (the engine, compiled), `sigillion-capture` and

- `sigillion-format` (readable source). This repository holds the README, the waitlist (issues), the releases, the

- privacy note, the terms and the website (`docs/`).

pipx install --include-deps sigillion

sigillion install

+ sigillion install cursor

- Then `sigillion status`. To remove it: `sigillion uninstall`, then `pipx uninstall sigillion`; what was kept stays in

- `~/.sigillion` until the user deletes it. Recording is free for good; reading back needs a licence after a 30-day

- trial; export with `sigillion-reader` always works.

+ `sigillion install` is for Claude Code and `sigillion install cursor` for Cursor: use one of them or both. After

+ `sigillion install cursor`, restart Cursor once. Then `sigillion status`. To upgrade from an earlier version: close

+ every Claude Code session and every Cursor window, then `pipx install --include-deps --force sigillion`, then

+ `sigillion install` again. To remove it: `sigillion uninstall` (in Cursor: `sigillion uninstall cursor`), then

+ `pipx uninstall sigillion`; what was kept stays in `~/.sigillion` until the user deletes it.
