In plain words
What is it for?
Use it to plan or build a SaaS product, including authentication, billing, databases, APIs, frontend work, and growth features.
Why use it?

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

ccc-saas 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 5d 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.

$ccc-saas — SaaS work, routed

CC Commander · $ccc-saas · the right SaaS method for the job, from scaffold to revenue.

SaaS sub-skills (saas-router, saas-scaffolder, better-auth, database-designer, drizzle-neon, api-design, backend-patterns, fastify-api, nextjs-app-router, shadcn-ui, tailwind-v4, stripe-subscriptions, billing-automation, webhook-patterns, multi-tenant, feature-flags, saas-metrics-coach, signup-flow-cro, paywall-upgrade-cro, form-cro) ship with the Commander CLI toolkit. Invoke one with the Skill tool when it is listed in this session; otherwise apply the focus in references/routing.md. The user's selected model is preserved.

Codex: ask pickers as plain-text questions.

When to use / when not to

  • Use for a multi-user product with accounts, billing or tenants: new SaaS, adding auth or Stripe, schema and API design, upgrade and signup conversion, SaaS metrics.
  • Use $ccc-build for a plain web app, API or CLI without SaaS concerns, $ccc-design for visual direction, $ccc-marketing for acquisition beyond the product funnel, $ccc-data for warehouse and analytics pipelines.

What happens

1. Detect the stack

Run in one Bash call, silent on failure:

test -f package.json && grep -oE '"(next|fastify|express|drizzle-orm|@neondatabase/serverless|prisma|better-auth|next-auth|@clerk/nextjs|stripe|tailwindcss|posthog-js|launchdarkly-node-server-sdk)"' package.json | sort -u
ls drizzle.config.* components.json prisma/schema.prisma 2>/dev/null

Render one line:

🏗️ Stack: <tools detected | none detected>

2. Route by intent, or ask

An argument or a clear intent routes straight to the sub-skill(s) in references/routing.md. new, or no codebase with a build request, goes to step 3. A request that spans several areas (zero to MVP, add billing, growth) follows the matching campaign in that file, one sub-skill per step, and confirms the sequence with the user before the first write.

Changes

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.
