Heph

Heph is the agent brain the user talks to.

It owns the user-facing agent identity, research/talking orchestration, the command entrypoint, slash-command coordination, and the composition needed to connect the harness, AI runtime, interfaces, and extension contracts.

The validation layer is the harness.

Source Layout

src/
  heph/
    cli/       Console entrypoint and top-level command routing
    commands/  Slash-command registry and command coordinators
    sdk/       Programmatic runtime/session surface for native apps and automation
    product/   Temporary bridge for Heph self-knowledge context
    identity/  Stable agent identity target
    prompts/   Prompt-program target for Heph-facing behavior
    state/     Declarative state contract target

The product/ bridge exists for current self-knowledge routing. It should stay thin and should not become a second harness or a place for domain behavior.

Boundaries

Heph is protected as the brain and composition layer. Lower packages must not import it, and optional behavior should extend Heph through contracts or composition instead of modifying harness or AI internals:

• Heph calls the harness for grounded answering, validation, citations, retrieval, memory, and armory workflows.
• Heph calls AI for provider/model runtime.
• Heph calls Interfaces for terminal and TUI presentation.
• Heph calls Extensions for stable extension contracts.
• Heph exposes SDK wrappers for non-terminal clients; those wrappers must stay UI-neutral and must not import interfaces.*.

Reusable validation behavior should move to the harness. Provider/API behavior should move to AI. Conversational strategy, research orchestration, and Heph-facing identity should stay here or move here as the migration continues.
