# NextEleven

We build practical AI systems and open-source tools that help developers control
agent actions, inspect their sources, and verify how software behaves.

## Start with DeadBolt

**Let agents work. Keep control of their actions.**

DeadBolt is a free local execution gate. Put it into the trusted code that performs
an action, then apply policy, leases, operator approval and revocation at dispatch.
Choose embedded Rust, local HTTP clients, a trusted stdio MCP proxy, or the
prerelease OpenAI Agents SDK function-tool adapter.

- [Install, integrate and inspect the source](https://github.com/seanebones-lang/deadbolt)
- [Complete developer walkthrough and transcript](https://seanebones-lang.github.io/deadbolt/#watch)

Stable **v1.0.3** and published prerelease **v1.1.0-rc.1** are available. Exact-action
approvals and scoped admission credentials are prerelease features. DeadBolt
protects routed actions; it is not an OS sandbox or a compliance certification.
Read the [trust boundary](https://github.com/seanebones-lang/deadbolt/blob/v1.1.0-rc.1/docs/TRUST.md).

## Search across your own files with PersonalRAGVault

Local document retrieval across notes, PDFs, code and supported saved exports,
including file-based Obsidian vault integration. Inspect matching passages and
sources through a CLI, optional browser UI or local HTTP API. Free under MIT.

- [Released 1.5.1 application and installation guide](https://github.com/seanebones-lang/personal-RAG)

Both Spaces are **free static showcases of recorded application results**.
They do not run agents or search your personal files on Hugging Face.

## Build or improve software with us

NextEleven also offers software engineering and practical AI consulting.
Bring an existing application, an integration problem, or a workflow you want to
improve. We value a short path from the problem to a tested working system.

This card and the showcases were prepared with AI assistance. Capability claims
are grounded in the linked released source; recorded examples are demonstrations,
not evidence of adoption or universal effectiveness.
