name	competitor-watch
description	Weekly snapshot of top competitor ASINs — listing changes, BSR shifts, review velocity changes, new SERP entrants. Pulls SellerApp data and diffs vs prior week. Use when running `competitor-watch {portfolio}` weekly via `/loop weekly`. Companion to the existing `competitor-tracker` agent (this is the skill-level wrapper).

competitor-watch — Weekly Competitor Drift Detection

Active CRO clients need to know when their competitors move — new product entrants, pricing changes, listing refreshes. This catches it weekly.

Prerequisites

• SellerApp via n8n MCP

Invocation

competitor-watch {client-slug}
competitor-watch --asin={ASIN} --top-N=10

Output

/tmp/cro-research/{client}-competitor-watch-{date}.md

Phase 1 — Load Watchlist

State at /tmp/cro-research/.competitor-watch/{client}.json:

• ASIN of own product
• Top N competitor ASINs (from latest competitor-sweep)
• Last-run snapshot

If no state: trigger competitor-sweep first.

Phase 2 — Pull Current Snapshot

For each watched ASIN: Get_Product_Details (with ratings, price, history flags) + Get_Product_History_30d_.

Phase 3 — Diff vs Prior Snapshot

For each ASIN, detect:

• BSR shift (>10% movement in either direction)
• Price change (>5%)
• Rating change (>0.05)
• Review count surge (>20% week-over-week)
• Image change (image_urls[0] hash differs — possible new main image)

Phase 4 — New Entrants

Re-pull SERP for primary keyword. Anyone in top 10 not in last week's top 10 = new entrant. Flag.

Phase 5 — Output

# Competitor Watch — {client}

**Week of:** {date} | **ASINs watched:** {N+1} (your + N competitors)

## Movers This Week

## New SERP Entrants

🆕 Brand X (B0...) — entered #7 for "{keyword}"

## Alerts

🟡 **Comp 2 dropped price** — review your pricing position via `price-sensitivity`

## Recommended Actions

- {specific action per alert}
- Schedule via `/loop weekly competitor-watch {client}` if not already
