The source didn't share its exact prompt, so we wrote this from what it describes.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Build me an early retirement plan for retiring at 30 in Vancouver, and give me the results as a downloadable presentation.

Check with me first: What's my current age, income, savings and monthly spending, roughly?

What I'll give you:
- My city (Vancouver here) and target retirement age
- My rough income, savings and spending, if I want the plan based on my numbers

Rules:
- Research the local tax rules that apply.
- Look at typical monthly spending, work out the savings needed to retire at 30, and research investment allocation and tax-saving strategies.
- Build several FIRE (early retirement) scenarios.
- If something is missing or unclear, ask me instead of guessing.
- Show your assumptions and sources. This is research, not personal financial advice.
- Stop once the presentation is ready and hand it to me.

Output: A downloadable presentation with the tax research, savings targets, investment ideas and each scenario.

You'll know it worked when: I have a presentation that shows how much I'd need to save and what each scenario looks like.

Here's a task I'd like your help with. Read it all the way through before you start.

Goal: Build an early-retirement plan for retiring at 30 in Vancouver and export it as a presentation.

Quick check first: tell me if anything below is missing or unclear.

Inputs (fill in or confirm):
- Age, income, savings, spending
- Target age and city
- Risk tolerance
- Current account types (TFSA, RRSP, taxable)
- Housing plan (rent or own)
- Downloadable format (slides or PDF)

Rules:
- State all assumptions (returns, inflation, withdrawal rate) on one slide.
- Show scenarios: base, cautious, optimistic.
- Use current Canadian tax and account rules with sources.
- Say this is educational, not financial advice.
- Include Vancouver-specific costs (rent, transport, healthcare premiums) with sources.
- Show what changes if retirement slips to 35 or 40.
- Highlight the 2–3 assumptions that move the result most.
- Don't give personalised investment product picks; describe options generally.
- Remind me it's not financial advice and to check with a professional.

If you get stuck: If data is missing, ask instead of assuming. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Check the maths in a spreadsheet you attach.

Output: Slides plus spreadsheet.

Done when: I can see how much I need to save under each scenario.
