Vraelis Prompto

Vraelis Prompto is an open-source tool that locks AI model folders and coding-agent add-ons to their exact bytes, offline, and tells you when anything changes.

Vraelis Prompto keeps a lockfile of exactly what you approved, then tells you later whether it is still the same. It runs offline, never loads a model and never launches anything. The command is vraelis.

Runs on: Windows, macOS and Linux. Standalone downloads need nothing else; the Python package needs Python 3.11 or newer
Network: None. The optional signature check is the one command that contacts Sigstore

Two locks, one tool

vraelis models pins the exact bytes of an AI model folder (safetensors, GGUF, configs, tokenizer) and checks its structure. Model folders
vraelis agents (preview) pins an AI coding agent's add-ons: MCP servers, Claude Code settings, skills, agents and commands, and the local scripts those configs launch. Agent add-ons

Every result is one of Unchanged, Changed or Can't verify, and says what it shows and what it does not. Nothing here is a security assessment. Results and exit codes

Alpha

Testing so far was self-run, not independent, and no outside user has run it yet. Interfaces and lockfile formats may change.
