One-Prompt Micro SaaS Architect
Example session with this skill installed
Build me a simple local-first task tracker for freelance developers that stores data in the browser and lets me export my logs to JSON.
- Read your context and instructions
- Compiled the one-prompt micro saas
- Generated the UI component
MODE: BUILD
1. What You Are Getting
FreelanceTaskTracker is a minimalist, local-first utility for developers to log time and tasks. It features a dashboard for active tracking, a history view, and a JSON export tool. It deliberately excludes cloud sync, user accounts, and integrated billing to maintain zero-infrastructure portability.
| Assumption | Default Used | How to Change It |
|---|---|---|
| Storage | Browser LocalStorage | Edit JS to use IndexedDB or an API. |
| Export Format | JSON | Modify the handleExport function in the script tag. |
| Persona | Individual Freelancer | Update CSS for different branding needs. |

# FreelanceTaskTracker
A single-file local productivity tool.
## Features
- Task logging with timestamps.
- LocalStorage persistence.
- JSON export.
4. File 3 of 3: DEPLOY.md
# Deployment
1. Save `index.html` to your computer.
2. Open it in any modern browser.
3. No hosting required, but works on Vercel or GitHub Pages.
5. 60-Second Test Checklist
- Open file in Chrome/Firefox.
- Enter "Build API" and click Log Task.
- Refresh the page to verify persistence.
- Click Export to JSON and verify the download.
App reviewed and verified against internal standards.
Next steps
- Save the
index.htmlfile locally. - Run the 60-second test checklist.
- Host on a static provider if sharing is needed.

About this skill
Ship faster by eliminating the gap between an idea and a working prototype. This skill functions as a senior product engineer and indie-SaaS operator, converting short descriptions into either a fully functional single-file web app or a detailed, scored product blueprint ready for AI coding tools.
What it does
- Builds single-file apps by generating a complete, deployable
index.htmlwith all logic, styles, and assets contained in one file. - Generates product blueprints including data schemas, pricing models, and architecture decision records for complex SaaS ideas.
- Scores project viability using a fit-score rubric to determine if an idea is a "GO", needs a pivot, or should be stopped.
- Authors master build prompts that can be handed directly to tools like Cursor, Lovable, or Bolt to execute a full build.
- Creates deployment guides including a
README.mdandDEPLOY.mdspecific to the generated code.
How it works
- Intake: Provide a single sentence or paragraph describing an app, tool, or SaaS idea.
- Mode Detection: The skill automatically selects BUILD (for code) or FULL/QUICK (for planning) based on your phrasing.
- Execution: It normalizes the idea, fills gaps with an Assumption Ledger, and aggressively cuts features to maintain a tight MVP scope.
- Delivery: Receive code, documentation, or a structured planning contract without having to answer clarifying questions.
Frameworks & tools
This skill delivers local-first web applications using vanilla HTML, CSS, and JavaScript. For planning modes, it generates SQL schemas with row-level security and architecture decisions based on a stack-decision matrix.
Why this beats prompting it yourself
Most LLMs suffer from feature creep or generate broken, incomplete code with placeholders. This skill enforces a "single core job" philosophy and includes a verification phase that traces checks through the code to ensure the deliverable is actually runnable.
Use cases
- Rapid Prototyping: Turn a thought into a working calculator or dashboard in one interaction.
- SaaS Planning: Generate a technical spec and data model for a subscription business.
- Idea Auditing: Review an existing product concept against a viability rubric to find gaps.
- Prompt Engineering: Get a production-ready system prompt to feed into another AI builder tool.
Known limitations
Does not build illegal or deceptive tools. Single-file apps lack persistent backends; complex state requires a switch to planning modes. No revenue or market success guarantees.

No support for illegal/deceptive tools. Single-file apps are local-first with no server-side sync. Planning mode required for backend/auth. No market or revenue guarantees.
