An InfoQ 中文 AI&大模型 account of YC Paper Club's Harness Night says the same model weights can score from 30% to 95% or even 100% on ARC-AGI when the harness changes. Seth Karten described a harness as an expressive layer spanning model weights, active context with a REPL, and filesystem-like scheduling state, with compression, CRUD operations, and refinement connecting the layers. Other talks addressed hardware limits and organizational issues involving permissions, trust, and collaboration.

Running untrusted agents and tools requires isolation, identity, network controls, and careful management of workloads that spend much of their time idle. Agent Substrate addresses these needs by providing a Kubernetes-based runtime that sandboxes each workload, withholds sensitive credentials, mediates outbound traffic, and suspends idle actors until they are needed.
Key fe…

Kubernetes environments need networking, load balancing, cross-cluster connectivity, identity-aware policy enforcement, service mesh capabilities, and operational visibility. Cilium addresses these needs through an eBPF-based dataplane that decouples security policies from network addressing and supports multiple routing and service-mesh approaches.
Key features
Flexible Kub…

Teams often rely on separate tools for communication, tasks, documents, customer relationships, and other work, leaving context scattered across systems. Macro addresses this by bringing those workflows into one connected interface where linked records remain searchable and available to both people and agents.
Key features
Connected team workflows — Email, messages, docs, ta…
What problem it solves
Python projects often spread their packaging and dependency metadata across several files such as setup.py, requirements.txt, setup.cfg, MANIFEST.in and Pipfile, which makes the dependency stack harder to keep consistent. Poetry consolidates that metadata so a project declares its dependencies and stack in one place, ensuring the right stack everywhere.
Key features
Single-f…

Security teams need to normalize heterogeneous telemetry, detect and correlate threats, investigate incidents, and prepare responses while retaining an auditable record of each agent step. These workflows also require explicit controls so that response actions are not sent to vendors without human approval.
Key features
Telemetry ingestion and detection — Normalize incoming …

Coding agents often need to trace API call chains before testing a backend, while regressions can involve changes spread across earlier calls and later reads. shrt records approved call chains and their responses as baselines so later releases can be replayed and compared. When a response changes, it identifies the affected step, field, and potentially responsible write.
