How Kiro Cut My API Integration Time from 4 Hours to 10 Seconds

Source: Dev.to

Enter Kiro

When the hackathon started, I thought Kiro was just another AI code assistant. It turned out to be much more: it forces you to think in specs, architecture, and clarity before you even touch code.

Specs Changed How I Think About Code

Before Kiro:
Write code first, then refactor.

After Kiro:
Write a spec first, then generate code.

Here’s an actual spec I wrote:

adapter:
  # define the adapter purpose and endpoints
code_structure:
  # outline modules, classes, and file layout
generation_instructions:
  # detailed instructions for the AI generator

It took me 30 minutes to write the spec, but the spec becomes the blueprint, documentation, and quality gate for the generated code.

Vibe Coding Is Actually Magical

I gave Kiro the prompt:

“Generate a REST‑to‑GraphQL adapter that converts Stripe payment webhooks to Shopify order creation. Include retry logic and error handling.”

60 seconds later I got:

• Error classes
• Retry with exponential backoff
• Field mapping
• GraphQL client
• Fully typed, structured code
• Zero bugs

What normally takes me 4 hours came out in under a minute.

Steering Docs = Guaranteed Consistency

I wrote a simple rule:

All errors must return this structure:

{
  "error": {
    "code": "string",
    "message": "string",
    "details": {}
  }
}

Now every generated file follows this pattern automatically—like having an AI junior dev who actually listens.

Agent Hooks Automate the Boring Stuff

I created a hook to scaffold everything:

hook:
  actions:
    - Create spec file
    - Create template file
    - Create test file
    - Update service references

Before: 30 minutes of manual scaffolding
After: Instant generation

The Results

What Changed in My Workflow

The Aha Moment

Kiro isn’t replacing me—it’s amplifying me. I’m not writing less code; Kiro handles the syntax and boilerplate, letting me focus on architecture and problem solving.

Tips for Anyone Starting with Kiro

1. Always start with specs.
2. Iterate on steering docs to enforce patterns.
3. Review generated code like a PR.
4. Document everything—Kiro uses it as guidance.
5. Let AI handle the boring work (scaffolding, error handling, retries).

Final Thoughts

AI‑assisted coding isn’t the future—it’s already here, built for the Kiroween Hackathon 2024.
