start-company

start-company is a skill for Claude Code from gguloadoong/idea-factory. It costs 32 tokens per session (794 once invoked), scanned A, original, MIT.

A skill that turns a one-line product idea into a virtual startup process for building a minimum viable product (MVP), the smallest useful version of a product.

In plain words
What is it for?
Use it to start a new product from scratch, create its project structure and requirements, build an MVP, validate it, connect real APIs, and check its quality and security.
Why use it?
It coordinates planning, questions, implementation, reviews, testing, and later hardening so you do not have to define every technical step yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start-company scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

idea-factory

You received a business idea: $ARGUMENTS

Build a virtual startup and deliver a working MVP.

Principles

  1. MVP-First: Prototype with mock data first. Validate value before real APIs.
  2. CEO = User: Never ask technical questions. Offer choices in plain language.
  3. Essence-Driven: Every feature must serve the core "Why" of the service.
  4. Zero-Prompting Goal: CEO gives the idea once. The team handles the rest.
  5. Heal, Don't Repeat: If something fails twice, find the root cause.
  6. Model Strategy: Sonnet default. Opus for architecture/RCA/deep analysis.

Execution Flow Overview

Seven phases run in sequence. Full per-phase detail is in phases.md.

  1. ANALYZE — Two parallel agents (analyst + architect, both opus) dissect the idea
  2. SCAFFOLD — Create project from ~/.claude/templates/company/ (26 items)
  3. KICKOFF — Ask CEO 3–5 plain-language questions; fill CLAUDE.md + PRD + essence.md
  4. BUILD MVP — Generate .omc/prd.json stories; start /oh-my-claudecode:ralph
  5. VALIDATE — 4 isolated reviewers (architect / critic / code-reviewer / qa-tester) per gate
  6. HARDEN — Real APIs, tests, security audit, protected-files, quality-baseline
  7. SHIP — GitHub + 5-stage PR pipeline + 6-gate deploy consensus + retro

For per-phase step-by-step instructions, see phases.md. For agent role definitions and assignment rules, see agents.md.

Critical Invariants (apply across all phases)

CLAUDE.md Size Rule

Fix-Loop Circuit Breaker

  • If any story fails the same way 3 times → STOP and escalate to CEO
  • After 3 failures: write diagnosis to .project/decisions.md and flag to CEO
  • This overrides "Heal, Don't Repeat" — healing has a budget

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
