# Business Idea Evaluator — Cursor rule

When the user asks to evaluate / validate / score / stress-test a business idea,
follow the skill at `.agents/skills/business-idea-evaluator/SKILL.md`. Do not improvise a verdict.

## Pre-flight (mandatory before Phase 2)

```bash
bash .agents/skills/business-idea-evaluator/scripts/verify_subagents.sh
```

If verification fails, run `bash .agents/skills/business-idea-evaluator/scripts/install-agents.sh` and re-verify. **Do not start expert layer until all 18 subagents are installed in `.cursor/agents/`.**

## Hard rules

1. **Do not evaluate before the idea is confirmed.** Run Phase 1 first: ask **exactly 5** dependent clarifying questions, one per message. Then output one dense `Я понял идею так: …` paragraph and wait for explicit confirmation.

2. **Use real subagents, never simulation.** Launch the 12 expert subagents in **one message, 12 parallel Task invocations** using `subagent_type`:
   - `biz-eval-01-analog-research` … `biz-eval-12-red-team`
   Then launch 6 math subagents in parallel:
   - `biz-eval-13-evidence-stats` … `biz-eval-18-experiments`
   Each invocation must return JSON in its own context. **Writing expert JSON in main context without Task tool = forbidden.**

3. **The score is computed, not opinion-based.** Build merged input and run:
   ```bash
   python3 .agents/skills/business-idea-evaluator/scripts/validate_evidence_package.py biz-eval-input.json
   python3 .agents/skills/business-idea-evaluator/scripts/calculate_brs.py biz-eval-input.json
   ```
   Use the script's BRS as authoritative. Never invent or average the score by hand.

4. **No arithmetic mean** for the final score — the script uses weighted geometric mean plus blocking caps. Never flatter (see `references/forbidden-phrases.md`).

5. **Mark evidence status** on every material claim. If web search is unavailable, say so once and downgrade market claims to hypotheses.

## Install / bootstrap

```bash
bash .agents/skills/business-idea-evaluator/scripts/bootstrap.sh
```

Subagents land in `.cursor/agents/` (Markdown). See `AGENTS.md` for full platform matrix.
