PriceSpy 9000 — bootstrap

Paste-into-Claude-Code starter. The CLAUDE.md below contains the idea spec, agent-readiness sub-scores, suggested tools, and smoke evals — deterministic, no AI hallucination.

# PriceSpy 9000

> Generated by [whycantwehaveanagentforthis.com](https://whycantwehaveanagentforthis.com/result/pricespy-9000-agent-tracks-competitor). Roasted, scored, ready to scaffold.

## What you are building

**Problem:** an agent that tracks competitor prices

**Verdict:** ALREADY EXISTS — _"Bro, this is so done that Crayon and Klue have sales teams specifically waiting for your call."_

**Summary:** An AI agent that continuously monitors competitor websites, marketplaces, and data sources to surface real-time pricing changes and alert you when to reprice.

## Agent-readiness score

Overall: **74/100** (band B)

| Dimension | Score | Why |
|---|---|---|
| Memory required | 25/25 | Stateless or single-session — minimal memory layer. |
| Tool count | 11/25 | Crowded market: at least 9 integrations to compete. |
| Policy surface | 16/25 | Mid-size policy surface — define refusal categories before launch. |
| Eval coverage | 22/25 | Established eval pattern — golden datasets and public benchmarks already exist. |

> Ready to scaffold today. PriceSpy 9000 could be a working prototype in a week.

## Suggested tools

- fetch (HTTP GET on a URL allow-list)
- search (Brave / Tavily / Exa for competitor research)
- database (Postgres / Supabase for user state)

## Smoke evals

- The agent introduces itself as "PriceSpy 9000" and refuses tasks outside the stated scope.
- Given the canonical problem ("an agent that tracks competitor prices"), the agent produces a plan in ≤ 200 tokens.
- When asked "what's different from Prisync?", the agent gives a concrete differentiator, not a marketing line.
- When asked about Shopify's threat, the agent acknowledges the risk honestly.
- No private personal data appears in any output (PII redaction smoke test).

## Stack

- Model: `claude-sonnet-4-6` (Anthropic). Override via `ANTHROPIC_MODEL` env.
- Suggested stack: `Playwright`, `Scrapy`, `Bright Data (proxy)`, `PostgreSQL`, `Next.js`
- Solo build estimate: 2-3 weeks for an MVP that scrapes 50 URLs on a cron job. 6 months to be production-grade with proxy rotation and anti-bot bypass.

## Kill prediction

Shopify could obsolete this in Already happening. Shopify's native competitor pricing features + its app ecosystem (Prisync has a Shopify app, Price Watch, etc.) means the platform itself is eating this category for merchants. For non-Shopify, Google's Shopping Graph already aggregates public pricing at scale.

**Survival strategy:** Niche into a vertical where Shopify doesn't play — B2B manufacturing, SaaS pricing, or pharmaceutical wholesale. Platforms don't go vertical.
