saas-kit

saas-kit is a skill for Codex from dublyo/saas-skills. It costs 140 tokens per session (1,165 once invoked), scanned A, original, MIT.

A step-by-step planning workflow for building software-as-a-service products, such as dashboards, CRUD apps, and admin tools. It creates a written product specification before any implementation code.

In plain words
What is it for?
Use it to define an SaaS product, write its specification, turn that specification into plans and tasks, and review or evolve an existing product. SaaS means software people use online, often with accounts or subscriptions.
Why use it?
It prevents coding from starting before the product’s purpose, users, and workflow are clear. It also separates planning, review, and implementation so unclear requirements are found early.

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-kit 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 10d 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 Kit

Operating Rule

Do not write or edit implementation code until the user has approved a spec.

Use this order:

  1. Establish or note the SaaS constitution and project rules.
  2. Clarify the SaaS product with one question at a time.
  3. Produce a full human-readable SaaS spec.
  4. Map the spec to Spec Kit/manual artifacts.
  5. Create or update a plan, checklist, and tasks only after the spec is clear.
  6. Ask for explicit approval before implementation.
  7. Only after approval, inspect or modify implementation files.
  8. Analyze before implementation and converge after implementation.

If the user asks for a review or audit, stay read-only unless they explicitly ask for fixes.

Question Protocol

  • Ask at most 10 questions.
  • Ask exactly one question per message.
  • Each question must have exactly four choices: A, B, C, D.
  • Each question must build on the previous answer.
  • Recommend one option when helpful, but still present all four.
  • Stop early when the product direction is clear enough to write a useful spec.

Prioritize questions in this order:

  1. Primary SaaS job and target user
  2. Core workflow and success moment
  3. Dashboard views and daily user actions
  4. CRUD objects and ownership rules
  5. Roles and permissions
  6. Workflow states and transitions
  7. Data/provider constraints
  8. UI density and operational needs
  9. Testing and verification expectations
  10. Implementation scope and first release boundary

Planning Bias

Focus on the app's real work, not marketing copy or premature architecture.

Default assumptions:

  • Product: core SaaS workflows, dashboards, CRUD, and business functions first.
  • Frontend: functional dashboard-first UI, Tailwind CSS by default.
  • Backend/data: provider-neutral first; map to PocketBase or Supabase after workflows are clear.
  • New app defaults: Next.js, Nuxt.js, or Astro.js for frontend; PocketBase or Supabase for backend/data.
  • Existing app: inspect repo conventions after spec approval and follow existing patterns.

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.
