# Vestige **Memory your AI can prove. A guard that stops it before it breaks things.** Vestige gives AI agents a memory that gets sharper over time, and a guard that checks your agent's tool calls before they run. Every memory has a receipt. Every stop has a reason. Nothing is guessed. [](https://github.com/samvallad33/vestige/releases/latest) [](https://github.com/samvallad33/vestige/actions) [](https://github.com/samvallad33/vestige/releases/latest) [](LICENSE) ## Quick start 1. Install the binaries (macOS and Linux), or download them for your platform from [Releases](https://github.com/samvallad33/vestige/releases): ```bash curl -fsSL https://raw.githubusercontent.com/samvallad33/vestige/main/scripts/install.sh | sh ``` 2. Run `npx @vestige/init`, choose Memory or Memory plus guard, and confirm. 3. Restart your AI client, then say: *"Tell me something about a friend."* Ask about them later. ## It remembers what matters Save *"Maya felt off after dinner at Bangkok Garden."* Later, save *"Maya has a peanut allergy."* Vestige sees that both memories are about Maya and raises the older one. When your agent plans Maya's birthday dinner, that dinner comes up first. This is **Retroactive Salience Backfill**: when something new makes an old memory matter, Vestige brings it back. It runs on every save, records every change it makes, and any change can be undone. [How Backfill works](docs/REFERENCE.md#retroactive-salience-backfill). ## It proves what it knows Memory lives in **Strata**, an append-only log. Every write passes a gate and returns a receipt. A memory is found by its exact id or tag, never by a lookalike. When something breaks, `causal_walk` follows the recorded links backward to the cause. Point `gather` at a GitHub issue and it walks back from there. ## It stops what you never approved **Operator Lite** is a free guard for your agent's tool calls. It stops force pushes, dropped tables, recursive deletes and production deploys before they run, even when the command is disguised. 30 rules: 15 stop the call, 15 record it for you to review. ```bash curl -fsSL https://raw.githubusercontent.com/samvallad33/vestige/main/operator-lite/operator-gate.py -o /tmp/operator-gate.py && python3 /tmp/operator-gate.py install ``` Install replays your last 30 days of agent history and shows what it would have stopped. Nothing in that history is run. [Windows, OpenClaw, and every claim checked on your machine](operator-lite/README.md). ## Vestige Operator [](operator-lite/media/from-lite-to-operator.mp4) The owner's version of the guard. Write your own laws, see a Board of today's stops, and get a weekly Letter of what your agents tried. $149 once, every future version included.
