Giving AI Your Spec

Claude Code

Build this feature: [paste spec]

Codebase: React + TypeScript + Tailwind
Reference: src/components/Button.tsx for button patterns

Lovable

Build: [paste simplified spec focusing on outcome]
Make it look like Linear (minimal, clean)

Replit

Create: [paste spec emphasizing what user sees]
Use React. Keep simple.

See PROMPTS.md for patterns.

Build in Pieces, Not All at Once

The biggest mistake non-technical founders make: giving AI the entire spec and hoping it comes back perfect. It won't. AI tools work best in focused chunks.

The Build Loop:

1. Pick ONE piece (a single feature or flow)
2. Give AI a clear spec for just that piece
3. Test it — does the piece work?
4. Fix any issues before moving on
5. Pick the next piece → repeat

Good pieces (1-3 hours each):

User signup and login
Dashboard showing key metrics
Settings page with profile editing
One core workflow (e.g., "create an invoice")

Bad pieces (too big):

"Build the whole app"
"Build the dashboard with all integrations"
"User management with roles, permissions, and team features"

Quality Gate Between Pieces

Before building the next feature, check: Does the previous feature still work? Can you sign up, do the core action, and see the result? AI tools sometimes break existing features while adding new ones. Catch that early.

When to Start a Fresh Session

Start a new chat/session with your AI tool when:

AI has made 3+ attempts at the same fix without success — context is polluted
You're seeing new bugs appear every time a bug is fixed
The AI is going in circles (suggesting things it already tried)
You want to add a new feature after finishing the current one

When starting fresh, give AI a clear description of: what exists, what works, and what you need next. Don't assume it remembers.

Things AI Won't Add Unless You Ask

AI-built projects routinely ship without these. Add them explicitly:

Ask Your AI Tool to Add:
- [ ] Error tracking (Sentry) — so you know when things break
- [ ] Analytics snippet (Plausible, PostHog, or GA4) — so you know who visits
- [ ] Proper 404 page — so broken links don't show a blank screen
- [ ] Proper 500 page — so server errors show a helpful message
- [ ] Favicon — so your browser tab has an icon, not a blank square
- [ ] Meta tags (title, description, OG image) — so links look good when shared
- [ ] Loading states — so users know something is happening

Reviewing What AI Built

Test, don't just run:

- [ ] Looks right?
- [ ] Happy path works?
- [ ] Edge cases work?
- [ ] Works on mobile?
- [ ] Error messages clear?

Giving Feedback

Bad: "This doesn't work"
Good: "Clicking 'Save' does nothing. Expected: 'Saved!' message"

Template:

What I tried: [action]
Expected: [outcome]
Got: [what happened]

Iteration Expectations

Normal: 2-4 rounds per feature
First build: AI builds from spec, you find 3-5 issues
Second build: Fixes those, you find 1-2 more
Third build: Final polish

Stop when:

Happy path works
Edge cases handled
Mobile works
No obvious bugs

Don't iterate for:

Perfection
Features beyond spec
Premature optimization

Common Mistakes

Mistake	Fix
No spec	Use scope skill first
"Build a dashboard"	Specify what's on it
Skip edge case testing	Try breaking it
Accept without review	Always test
Add features mid-build	Finish current feature first
Fix code yourself	Describe problem, let AI fix

Right-Sizing Work

Too big: "Build entire app"
Too small: "Add one button"
Right: "Build user auth flow" (1-3 hours)

Good chunks:

User login/signup flow
Dashboard with 4 metrics
Settings page with profile editing

When Stuck

AI keeps breaking things: → Break into smaller piece, start fresh session

Can't figure out complex feature: → Ask: "What's simplest way?" Accept simpler solution

Each fix breaks something else: → Stop. Ask: "Better approach?" Consider starting over

Working with Existing Code

Add [feature] to existing project.

Stack: [React, Next.js, etc]
Patterns: Check src/components for examples
Style: Tailwind + custom design system
Follow existing code style

Prompting Patterns

Reference existing:

Build Settings page.
Reference Dashboard page layout.
Use same Card/Button components.

Provide examples:

Pricing page with 3 tiers.
Like Linear's pricing - clean, minimal.

Specify constraints:

Build profile page.
Must work offline.
Load under 2 seconds.
WCAG AA accessible.

See PROMPTS.md for more.

Review for Non-Technical Founders

Check:

Does it match spec?
Buttons work?
Forms validate?
Looks like design reference?
Works on mobile?
Error messages clear?

Don't check:

Code cleanliness
Optimization
"Best practices"

AI handles code quality. You handle requirements.

Success Looks Like

✅ Features match specs
✅ 2-4 iterations (not 10+)
✅ Can explain what's wrong
✅ Building faster each week
