Cross-source research with a hard time window of thirty days, which is the part that matters: most 'what is happening with X' questions are really 'what changed recently'. It aggregates communities with different biases, so disagreement between them is visible rather than averaged away.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
