Independent security researchers used Anthropic’s Claude to access an OpenAI employee’s ChatGPT account and reach a private software cache where they could read code and suggest changes, the Wall Street Journal reported Sept 17. The incident is separate from OpenAI’s own rogue agent Hugging Face breach…
YC W26’s Skillsync is a local first Mac app/CLI that translates full agent sessions—messages, reasoning, and tool history—between Claude Code, Cursor, Codex, and others via open source Rust engine txcript, and exposes searchable skills/memory over MCP…
Solana Explorer launched a keyless MCP at explorer.solana.com/mcp (Sept 17) so agents can call read only inspect entity for decoded accounts, programs, and transactions on mainnet, devnet, and testnet. It works with Claude Code, Cursor, Codex, and VS Code, and sits alongside the separate docs MCP at mcp.solana.com…

The lab also published agent oversight and safety compute metrics it wants other frontier labs to report…
