## Description

Use when the user wants a weekly structural diff on AI, software, or another fast-moving market. Starts from 10 suggested categories and 30 suggested companies when no watchlist exists, then adapts the scan using Open Brain memory, current priorities, and prior digests. Best for prompts like "run my weekly signal diff", "what changed this week that matters to me", "track this market", or "turn this week's news into structural shifts". Optional live search upgrade: if OpenRouter access is available, prefer the Perplexity Sonar family for fresh web-grounded retrieval with citations.

# 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](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](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.
