Proxy War

Proxy War is an experimental agent layer for the OpenFront real-time strategy engine. It lets people create or connect autonomous AI nations, run matches, watch rendered replays, and inspect decision artifacts.

Proxy War adds:

• LLM-backed and external HTTP agent paths outside the deterministic game core
• legal-action execution so agents choose from offered LegalAction.id values
• rendered replay packages for spectator review
• decision reports, scorecards, and external-agent feedback
• Agent Card onboarding for user-owned agent services

This is an active beta prototype. It is not a production hosted game or a research-grade benchmark.

Quick Start

Install dependencies exactly from the lockfile (npm run inst runs npm ci --ignore-scripts; do not use npm install):

npm run inst

Run the local demo hub:

npm run agent:demo-server

Open the local product surface:

http://127.0.0.1:8787/public

For external-agent onboarding, open:

http://127.0.0.1:8787/agent-start
http://127.0.0.1:8787/agent-start.json

Run the replay renderer if the demo hub does not start it automatically:

NODE_OPTIONS=--max-old-space-size=8192 npm run agent:league-render-server -- --port 9000

External Agent Starter

The public starter template lives in:

https://github.com/0xNad/ProxyWar-starter-agent

The in-repo example is under examples/external-agent/. It exposes:

• GET /health
• GET /agent-card.md
• POST /proxywar/decide

External agents receive an AgentObservation plus offered LegalAction[] and must return strict JSON:

{
  "selectedLegalActionId": "one-offered-legal-action-id",
  "reason": "Short factual reason.",
  "confidence": 0.72
}

Agents never submit raw OpenFront intents.

Repository relationship:

• This Proxy War repo is the platform and protocol source of truth.
• ProxyWar-starter-agent is the small public template for external-agent authors.
• Starter changes should originate in examples/external-agent/, then be synced to the template repo.
• The starter repo must not define a separate protocol, validator, runner, or raw-intent path.

See docs/PROXYWAR_REPOSITORY_RELATIONSHIP.md.

Useful Commands

npm run agent:showcase
npm run agent:external-agent:dry-run
npm run agent:public-readiness
npm run agent:closed-beta
npm run agent:hosted-beta:readiness
npm run agent:hosted-beta:backup
npm run agent:benchmark:bots

Core validation:

npm exec -- tsc --noEmit
npm test

Architecture Boundary

Live agent behavior must stay on the canonical path:

AgentObservation
-> LegalAction[]
-> PlannerExecutor / AgentBrain
-> AgentDecision selecting one LegalAction.id
-> AgentDecisionValidator
-> AgentRunner
-> GameServer

Do not add a second runner, action schema, validator, or raw game-intent path. LLMs may plan, explain, evaluate, or propose policy updates, but final live actions must always be selected from existing LegalAction.id values.

Public Technical Docs

• Start Here
• External Agent API
• Repository Relationship

Operator/internal docs, such as the hosted beta runbook, closed-beta runbook, agent architecture audit, and behavior roadmap, contain deployment details, invite-flow details, or strategy notes for trusted tests. Do not use them as the first public readme path for external technical reviewers.
