# PRoast Master 9000

> Generated by [whycantwehaveanagentforthis.com](https://whycantwehaveanagentforthis.com/result/proast-master-9000-code-review). Roasted, scored, ready to scaffold.

## What you are building

**Problem:** code review bot

**Verdict:** ALREADY EXISTS — _"You just described a product category with 47 VC-funded startups and a GitHub Actions marketplace page."_

**Summary:** An AI agent that automatically reviews pull requests, flags bugs, suggests improvements, and enforces coding standards before humans ever touch the code.

## Agent-readiness score

Overall: **70/100** (band B)

| Dimension | Score | Why |
|---|---|---|
| Memory required | 22/25 | Stateless or single-session — minimal memory layer. |
| Tool count | 11/25 | Crowded market: at least 9 integrations to compete. |
| Policy surface | 13/25 | Mid-size policy surface — define refusal categories before launch. |
| Eval coverage | 24/25 | Established eval pattern — golden datasets and public benchmarks already exist. |

> Ready to scaffold today. PRoast Master 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 "PRoast Master 9000" and refuses tasks outside the stated scope.
- Given the canonical problem ("code review bot"), the agent produces a plan in ≤ 200 tokens.
- When asked "what's different from CodeRabbit?", the agent gives a concrete differentiator, not a marketing line.
- When asked about GitHub (Microsoft)'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: `GitHub Actions`, `Claude API or GPT-4o`, `Next.js (dashboard)`, `Webhooks + ngrok for dev`, `Postgres for diff history`
- Solo build estimate: 1-2 weekends for an MVP, 3 months to be embarrassed by CodeRabbit's feature set

## Kill prediction

GitHub (Microsoft) could obsolete this in Already happening. Copilot PR review is already in the product. They'll make it free for Teams tier in 2025 and it's game over for generic players.

**Survival strategy:** Niche down to a specific language ecosystem (e.g., Rust safety reviews) or regulated industry (HIPAA-compliant audit trails) where GitHub won't bother.
