DRE — Domain Reverse Engineering

Analyze the business and domain side of a reference site, platform, or product: business model, positioning, marketing, ads, tech stack, financials, and pricing history — with evidence and explicit uncertainty on every claim. The business-side counterpart to REA, which covers the technical side.

Status: pre-release. 11 MCP tools built and tested; AC-008 (independent accuracy benchmark) is still pending real user labeling. See docs/adr.yaml for the design decisions behind each feature and .harness/ouroboros/ for the spec/eval history.

Principles

1. Only directly observed facts are labeled observed; the rest is inferred or estimated.

2. Estimates are ranges with stated assumptions, never single numbers.

3. Works with public sources and your own LLM key (BYOK). No paid data required.

4. DRE never bypasses robots.txt, bot/CAPTCHA detection, or login walls — see docs/adr.yaml ADR-004/005 for why (and why Meta's ad library is deliberately not covered: facebook.com's robots.txt specifically disallows ClaudeBot).

5. DRE never calls an LLM or search engine itself. When a collector is blocked, the calling agent may supplement with its own research, but must mark it source: "agent" and inferred/estimated — never observed (ADR-003).

Claim schema

Each claim has type (observed | inferred | estimated), confidence, evidence[] (each with an optional source: "dre" | "agent"), assumptions[]. Revenue-model labels are a fixed taxonomy with precise definitions — see packages/core/src/labels.ts and packages/core/src/schema.ts.

Develop

npm install
npm test
node packages/cli/dist/index.js eval reports benchmarks/gold   # AC-008 accuracy check

To rebuild the publishable dre-agents bundle after changing any package:

cd packages/dre-agents && npm run build

Optional environment variables

• DRE_DART_API_KEY — free key from opendart.fss.or.kr, enables collect_financials_kr

• DRE_SEC_USER_AGENT — your own "org contact@email" string for SEC EDGAR (recommended over the default)

• DRE_CHROME_PATH — Chrome/Chromium path, for JS-rendered pages (collect_pricing with js: true)

• DRE_ALLOW_PRIVATE_NETWORK=1 — local dev/testing only; disables the SSRF guard

Roadmap

• Done: pricing/terms/appstore/techstack/ad-library/financials(US+KR)/price-history/jobs collectors, analyze_company orchestrator, npm packaging prep

• Next: traffic/CPC/CTR/CVR/ROAS scenario estimates (user-supplied external API keys, stated assumptions — see non_goals in .harness/ouroboros/seeds/seed-v1.yaml for what DRE deliberately does not do)
