sdlc-startup

sdlc-startup is a command for coding agents from saitarrun/Devforge-ai. It costs 21 tokens per session (581 once invoked), scanned A, original, Apache-2.0.

A command that coordinates the development and operation of a software startup, from a minimum viable product (MVP) through billing, analytics, customer acquisition, and growth. An MVP is the smallest version that can test whether an idea works.

In plain words
What is it for?
Use it to scaffold an MVP and landing page, create Stripe subscriptions and usage billing, add PostHog analytics, design growth loops, or track MRR, CAC, LTV, and churn.
Why use it?
It brings product planning, payments, usage tracking, and business metrics into one startup workflow instead of treating them as separate tasks.

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

sdlc-startup 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 4d 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.

Startup Founder & Growth Command

This command orchestrates the business, monetization, product analytics, and customer acquisition loops needed to build and operate a high-growth software startup.

Usage

/sdlc-startup --mvp "AI claims copilot for insurance brokers" # Scaffold startup MVP, PRD, and landing page
/sdlc-startup --pricing stripe                                # Generate subscription tiers, customer portal & webhooks
/sdlc-startup --analytics posthog                             # Instrument North Star telemetry & activation funnels
/sdlc-startup --growth-loop                                   # Design viral loops, programmatic SEO, and referral engine
/sdlc-startup --metrics                                       # Generate live MRR, CAC, LTV, and churn tracker

Process

  1. Ideation to Minimum Viable Product (MVP):
    • Identifies high-conviction problem statement, 3 critical tracer bullet slices, and landing page waitlist.
  2. SaaS Billing & Monetization Generation:
    • Implements Stripe checkout, subscription webhooks, seat billing, and usage metering.
  3. Telemetry & Growth Loops:
    • Instruments activation funnels, session tracking (PostHog/Mixpanel), and automated customer feedback loops.
  4. Investor & Unit Economics Reporting:
    • Generates docs/startup-metrics.md tracking MRR, CAC, LTV, Churn, and Runway.

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.
