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.
- Install the binaries (macOS and Linux), or download them for your platform from Releases:
curl -fsSL https://raw.githubusercontent.com/samvallad33/vestige/main/scripts/install.sh | sh - Run
npx @vestige/init, choose Memory or Memory plus guard, and confirm. - Restart your AI client, then say: "Tell me something about a friend." Ask about them later.
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.
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.
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.
mkdir -p ~/.operator/downloads && curl -fsSL https://raw.githubusercontent.com/samvallad33/vestige/main/operator-lite/operator-gate.py -o ~/.operator/downloads/operator-gate.py && python3 ~/.operator/downloads/operator-gate.py installInstall 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.
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, and a 30-day refund if it is not for you.
