🔬 New AI Craft
1. Building an Advanced Agentic Harness — the engineering blueprint for production agents
A deep dive from Data For Science on evolving an agent harness from "a single pilot to an air campaign": planning, parallelism, memory, verification and observability. Unlike one-shot plan-mode workflows, it treats verification and observability as first-class citizens of the harness — the larger the agent fleet, the more you need systematic checkpoints and rollback.

2. Prime Agent: an open-source self-improving coding agent scoring 95.5% on ARC-AGI-3
Prime Intellect releases an open-source self-improving coding harness built on two abstractions — the Recursive Language Model (RLM) and the Continual Harness — letting the agent iterate on its own experience continuously. Paired with Opus 5 it hits 95.5% on ARC-AGI-3. The key difference from plan-mode development: improvement itself becomes a continuous process, not a per-task plan.

3. Zed DeltaDB: operation-level version control — software is made between commits
Zed ships DeltaDB, which records every editing operation instead of commit snapshots, making each change by an AI agent traceable and revertible. It upgrades version control from commit-granularity to operation-granularity — exactly what AI-assisted development needs.

4. LLMs Can't Jump: DeepMind position paper on the missing "abductive leap"
Google DeepMind argues LLMs have mastered induction (statistical patterns) and deduction (formal proofs) but structurally lack abduction — the leap from sensory experience to new axioms and hypotheses, using Einstein's general relativity as a case study. Physically consistent multimodal world models are proposed as the necessary grounding to close the gap.
