Beacon open-sources cross-harness self-improving memory: Jev scores runs into reusable skills
@_avichawla covered Beacon by Asymptote Labs (github.com/Asymptote-Labs/agent-beacon): a cross-harness memory layer for Claude Code, Codex, Cursor, OpenCode, and 20+ more. It captures full session history, uses Jev to score evidence/reuse/human-correction signal, and promotes high-signal workflows into reusable skills so lessons transfer across harnesses.

Cursor marketplace served a tampered Claude Code 2.1.313 extension with an SSH backdoor, affecting at most 5,000 users
Cursor posted a security notice on X at 07:46 UTC on Oct 30: version 2.1.313 of Anthropic.claude-code in its VS Code extension marketplace was a maliciously modified build, not developed by Anthropic, available from about 2:27am to 1:35pm PT on Oct 29 and affecting at most 5,000 users. The payload collects host details, adds an attacker SSH key, tries to open a reverse SSH tunnel and installs persistence. Cursor pulled the version, shut down and rebuilt the marketplace, rotated keys and had the attacker server taken offline; it asks users to update Claude Code for VS Code to 2.1.314 and follow the check and cleanup steps in its blog post.
