What’s inside

Everything in one vault.

I

Specs

Problem, goal, acceptance criteria, edge cases and security notes, on a board from idea to shipped.

II

Prompt library

16 prompts that make AI tools plan first, write tests, debug with evidence and review their work.

III

Agent context

Starters for AGENTS.md, CLAUDE.md and Cursor rules, plus a context-pack checklist.

IV

Decisions

Why you chose X over Y, so neither you nor the AI undoes it later.

V

Bugs

Open bugs grouped by severity, with root cause, fix and prevention.

VI

Ideas

Ranked automatically by impact × confidence × ease.

VII

Releases and sessions

Release notes per version, and a two-minute log after each AI coding session.

Launch checklists

Pre-launch security, launch day, the first week, and reviewing AI-written code.

Questions

Straight answers.

What is Obsidian?

A free note-taking app for Windows, Mac, Linux, iPhone, iPad and Android. Your notes are plain files on your own device, not in someone else’s database. Get it at obsidian.md.

Do I need plugins or coding?

No. Everything uses Obsidian’s built-in features (Bases, templates, daily notes), so it works with Restricted mode on, works on your phone, and keeps working when Obsidian updates.

What exactly do I get?

A ZIP with the complete vault: templates, ready-made views, guides, and fictional sample data you can clear from one list. Open the folder in Obsidian and the Home page appears.

Can I change it?

Yes, all of it. Rename statuses, add fields, delete what you don’t need. It’s yours to keep.

Does it work on my phone?

Yes. Use any sync you like (Obsidian Sync, iCloud or a free option); a guide inside compares them.

Is my data private?

Yes. The vault runs on your devices and we never see your notes. It’s designed to never hold passwords or ID numbers.

What if it isn’t right for me?

Email us within 14 days of buying and we’ll refund you. No form, no argument.

Do I get updates?

Yes, free for 12 months: re-download from the link on your purchase page.
