JARVIS Runtime Model

This repo will contain the shared data model and schemas used by the ARP ecosystem:

• Agent Runtime Instances
• Tool Registry
• Clients/SDKs

Current phase: MVP with basic standard library tools only.

Design docs

• docs/intro.md
• docs/design/overview.md

What’s implemented

• jarvis_model/: dependency-free Python package with:
  • core types (FlowRun, FlowStep, ToolDefinition, ToolInvocationRequest, ToolResult, Error)
  • a small JSON Schema validator for tool arg validation
  • JSON Schema exports in jarvis_model/schemas.py

Install

Pre-release:

pip install --pre jarvis-model

Run tests

From Repos/Jarvis/Model:

python3 -m unittest discover -v

Or pytest:

pytest -q

Install (dev)

From the repo root:

python3 -m venv .venv
source .venv/bin/activate
pip install -e .

MVP capabilities + known gaps

Capabilities:

• Shared, versioned types for flows/steps, tool definitions, invocations, and results.
• JSON Schema exports and a lightweight tool-args validator (stdlib-only).

Known gaps:

• Not a full ARP wire-protocol spec yet (transport/network protocol is explicitly out of scope for the MVP).
• Compatibility/versioning policy beyond schema_version is still minimal.
