## About

Firefighter is an experimental software harness that uses a local LLM with root access to continuously patch servers against vulnerabilities. It listens to official vulnerability sources centrally, investigates exposures locally, applies fixes, and verifies service health without runtime approval prompts. The project operates on the hypothesis that faster automated responses can reduce security exposure.

## Who it's for

System administrators and developers willing to run experimental and potentially risky autonomous root-level tools.

## Use cases

- Continuously patching servers against newly published vulnerabilities
- Automating code and package fixes without manual confirmation prompts
- Broadcasting vulnerability notices from a centralized hub to client servers

## Features

- Centralized hub broadcasting official vulnerability notices
- Local LLM investigation of server versions, exposures, logs, and evidence
- Automated application of package or code fixes with testing and rollback support
- Local recording of commands, results, verification, and recovery attempts
- Configured key rotation hooks and reporting to a chosen agent

## FAQ

### What does Firefighter do?

Firefighter is a harness that constantly and continuously patches your server by running with root access and zero confirmations using a local LLM.

### Is Firefighter safe to run?

No, it is an unproven root-LLM paradigm where a mistaken decision, bad patch, malicious input, or compromised dependency could delete your entire server, break services, corrupt data, or expose secrets.

### Will it ask before making changes?

No, there are no runtime approval prompts and everything happens automatically while sending reports to a configured output and keeping local audit logs.

### What does running Firefighter cost?

You pay for your client's model API usage and server resources, while the shared hub currently mirrors official sources for free.

### Can the central site tell my server what to do?

No, the central site only broadcasts vulnerability notices, and your local LLM running in the Firefighter harness decides what to do.
