# JIT-Agent — compare, do not clone
## When
JIT-Agent, arxiv 2608.25593, Rohan Paul harness intelligence, Model-as-a-Harness,
just-in-time harness evolution, HarnessFactory, four-module agent harness.
## Do
```bash
npx thumbgate jit-harness-compose --task="<what the agent should do>" --json
npx thumbgate jit-harness-compose --map-only
```
Map modules to existing rails:
- **memory** → lesson-retrieval / feedback / contextfs
- **planning** → `bin/agent-loop` Plan + GSD
- **action** → PreToolUse gates + `harness-selector` + `switchyard-router`
- **capability** → `subagent-profiles` + MCP allowlists + skills + model pool
## Never
- Train, serve, or download JIT-Agent-27B / `huggingface.co/JIT-Agent`
- Clone `bingreeky/JIT` HarnessFactory into ThumbGate
- Emit free-form harness programs as a new SKU
- Claim ThumbGate is JIT-Agent
