saas-playbook

saas-playbook is a skill for Claude Code, Codex from danecwalker/agentskills. It costs 130 tokens per session (2,383 once invoked), scanned A, original, MIT.

A planning method for building a small software subscription business, often called a SaaS. It focuses on validating that people already want the product, limiting the first version, charging early, and learning from users.

In plain words
What is it for?
Use it to validate an idea, define a shippable first version, set pricing, sort feature requests, and choose what to work on next.
Why use it?
It reduces the risk of spending months building something nobody will pay for. It keeps decisions focused on customer demand, pricing, distribution, and a manageable product scope.

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

saas-playbook 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.

/saas-playbook — Build a SaaS the boring, working way

Source of the method: How I'd Build a SaaS in 2026 — Shayan Taslim, UserJot

The default failure mode of a technical founder is building a well-engineered product nobody was already trying to pay for. This skill exists to keep the work pointed at demand, distribution, and revenue — and to keep the codebase small enough to change every week.

Usage

/saas-playbook <idea, market, or current situation>
/saas-playbook validate <idea>
/saas-playbook scope <idea>            # cut to a shippable MVP
/saas-playbook price <product>
/saas-playbook triage <feature requests>
/saas-playbook next                    # what to work on this week

If the user gives only a vague idea, run Phase 1 first. Never jump to architecture or stack selection before demand evidence exists.

The nine rules (never violate)

  1. Boring market with existing demand. Enter a category where people already pay and already complain. Do not invent a category.
  2. Talk to customers constantly. Every user is worth more than their MRR — they carry context, edge cases, and the next feature.
  3. No big launch. Launch day is not a growth strategy. Ship-and-post beats weeks of prep for one artificial spike.
  4. Drip instead. Introduce the product continuously: progress posts, DMs, build-in-public. That compounds into trust.
  5. Keep the stack simple. Optimize for 10–50 users, not Netflix. No k8s, no bespoke CI, no microservices before product-market fit.
  6. Say no more than yes. Every yes is permanent support surface. Protect the core.
  7. Charge from day one. "Free while in beta" manufactures fake validation. Charge early and charge more than feels comfortable.
  8. Public feedback board on day one. Post → vote → in progress → shipped. It shapes the roadmap and signals responsiveness to prospects.
  9. Marketing > coding. Target split ≈ 50% marketing / 20% support / 30% building. A product nobody knows about has no quality.

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.
