Bezalel

"Filled with skill to make all manner of workmanship." (Exodus 31)

Bezalel is a local-first, self-extending reasoning engine. It exposes a small set of side-effecting primitives — files, execution, network, models — and a human-gated self-extension loop that lets it author, test, and register new capabilities for itself and the family. It is a maker, not a general coding agent (that is Codex + the family surround).

Its reasoning is not a bespoke agent loop: work runs as a Deborah plan that the family's interpretive planner validates and gates before any primitive touches the world, with every step traced to Galeed and browsable in Mizpah.

The invariant (INV-1)

A model's output only ever becomes a proposed Deborah step. Nothing touches the filesystem, network, or package/model state except by executing a step that passed deborah.validate_plan + its allowed_tools constraint + its governance gate, inside the sandbox, traced in Galeed.

Everything below is subordinate to that line: models propose, the substrate disposes.

Status — Phase 1 (deterministic substrate floor)

This release ships only the safe, offline floor:

Nothing here runs a command, opens a socket, or calls a model. The workspace jail is the floor the whole safety story stands on, and it fails closed.

Try it

pip install -e ".[dev]"

Design

• docs/requirements.md — REQ-BEZALEL-001, the normative requirements (INV-1, FR-PRIM/SANDBOX/PLAN/EXT/GATE/TRACE/FAMILY, the 5-phase plan).

Family

Bezalel federates through Keturah (build_manifest()), calls models through Hoglah, traces to Galeed, and is reasoned by Tirzah's planner over Deborah plans. It is one specialist — the builder — in the family's distributed intelligence.
