Cross-Harness Export: One Component Pack Across Claude Code, Codex, and Ollama Cloud

Customers bring their own model access and harness. Here is how one AgentFoundry component pack mounts cleanly into Claude Code, OpenAI Codex CLI, and Ollama Cloud.


Baltor is not a vendor-locked model host. Customers bring their own API keys, sign-ins, or local endpoints (127.0.0.1:11434, Ollama Cloud, Claude Code, or Codex CLI) and use getagentfoundry.si to give their chosen harness verified materials, tools, and checks. Because the 8-file pack format uses plain Markdown, JSON Schema, YAML, and standard Python 3.11+ verifiers, a single pack mounts into all three harnesses without rewriting a line of logic.

Mounting an 8-file pack across three harnesses

Target Harness Discovery & Rule Entrypoint Action / Tool Binding Independent Verification Hook
Claude Code (claude) CLAUDE.md imports AGENTS.md + RULES.md .claude/settings.json + TOOLS.json Post-step hook runs python3 verifier.py
OpenAI Codex (codex) AGENTS.md + baltor_contract_card.json Sandboxed tool runner reads TOOLS.json WORKFLOW.yaml gate executes verifier.py
Ollama Cloud / Local System prompt loads < 2 KB contract card OpenAI-compatible tools array from TOOLS.json Loop Engine runner enforces verifier.py
# Verify an 8-file AgentFoundry pack locally against its conformance kit
curl -fsSL https://getagentfoundry.si/feed.json -o /tmp/agentfoundry-feed.json
python3 -m json.tool /tmp/agentfoundry-feed.json | head -n 20

Whether a developer runs gemma4:31b on Ollama Cloud for overnight batch solving or Claude Code interactively on a workstation, the contract card and verifier.py guarantee identical structural invariants.
