HackerRank Chakra

Chakra is HackerRank’s AI interviewer for coding-skills interviews. Candidates can use AI during an interview while Chakra observes how they use it and asks probing follow-up questions. The video describes it as publicly available after a beta in which it conducted approximately half a million interviews over six months, and names Capgemini among its users.

ResolveAI is an AI SRE platform for operating production systems, providing managed on-call and SRE agent teams for alert triage, incident investigation, root-cause analysis, recurring issue remediation, and operational automation. Its agents investigate across code, infrastructure, telemetry, observability data, knowledge bases, and production context supplied through Hivemind, which tracks production state, alerts, recent changes, on-call questions, and incident context. In a demonstrated workflow, a Grafana alert received through Slack triggers an investigation that builds a causal chain of evidence and rules out competing explanations before proposing or taking governed actions. ResolveAI agents can mitigate and restore services, escalate to engineers with context, supply production context to coding agents, support custom SRE agents for workflow-specific automation, and integrate with existing engineering tools. The platform combines model orchestration, context engineering, causal reasoning, governed actions, learning systems, evaluations, and domain models with frontier models.

Arize Skills is a set of installable skills for AI coding agents, maintained by Arize, that guides agents through adding observability, creating datasets, running experiments and evaluations, and optimizing prompts for LLM applications. The skills use the ax CLI to interact with Arize and include workflows for tracing and debugging applications, OpenInference-based instrumentation, dataset management, experiments, LLM-as-judge evaluators, annotations, prompt optimization, provider credentials, and production monitoring. They can be installed into agents such as Cursor, Claude Code, Codex, GitHub Copilot, and Windsurf through npx, the repository's installers, the ax CLI, or a Claude Code plugin. The repository is licensed under MIT.

Cursor is an AI-powered coding agent and integrated development environment designed to accelerate software development by handing off coding tasks to AI. It evolved from an email client into a multimodel development tool, supporting broader developer workflows. The platform also offers MCP-connected capabilities for tasks like searching and editing notes.

VI codebench is a coding benchmark that measures how well AI models turn natural-language prompts into full-stack web applications. It is associated with VALS, an AI evaluation company that develops continuously evolving assessments for measuring model performance before release and in practical coding workflows.
