jit-harness-compare-not-clone

JIT-Agent (arXiv:2608.25593) is a harness-intelligence model, not a ThumbGate clone. Steal the four-module FORMAT (memory/planning/action/capability) onto existing rails; never train or download JIT-Agent. Slash: /jit-harness-compare-not-clone.

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

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
  • planningbin/agent-loop Plan + GSD
  • action → PreToolUse gates + harness-selector + switchyard-router
  • capabilitysubagent-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
