Weekly Signal Diff

Problem

A wall of news does not tell the user what structurally changed. Most weekly roundups over-index on headlines, underweight economics and dependency shifts, and ignore what the user actually cares about. This skill turns a noisy week into a small set of structural changes, weighted by Open Brain memory.

When to Use

• Weekly market review or Sunday/Friday ritual
• "Run my weekly signal diff"
• "What changed this week that matters to me?"
• "Track this market and tell me the structural shifts"
• "Turn this pile of news into a decision-grade diff"
• Ongoing automation that writes a weekly digest back to Open Brain

Required Context

Gather as much as the environment allows:

• the user's active projects, bets, and recurring interests
• prior weekly digests or adjacent summaries stored in Open Brain
• the desired freshness window (default: last 7 days)
• any preferred outlets, banned sources, or explicit watchlist entities

If the user has not provided categories or companies, read references/starter-universe.md and use it as a bootstrap layer only.

If live web access is available and the user wants current coverage, read references/live-search-upgrade.md and use the strongest search mode the environment supports.

Process

1. Establish the frame.
   • Confirm the topic space, freshness window, and whether the goal is personal awareness, operator strategy, investor tracking, or content prep.
   • If the user says nothing, default to a 7-day operator-style review.
