What does it mean for a team to be "AI-native" rather than simply using AI tools?

Your answer

Re-explain

An AI-native team designs its delivery system around safe, repeatable AI collaboration; simply using AI means adding tools to an otherwise unchanged process.

Dimension Uses AI tools AI-native
Workflow Individuals prompt as needed Specifications, context, and tests guide agents
Control Existing review absorbs output Permissions and risk gates limit actions
Success Tool adoption or generated code Delivery quality, effort, and defects

People still own product choices, architecture, and released changes. The team maintains reusable instructions and evaluations, keeps project knowledge retrievable, and strengthens verification as generation becomes faster.

Your answer

Re-explain

AI-generated code deserves at least normal scrutiny because fluent syntax can hide false assumptions, invented interfaces, insecure patterns, or unintended scope.

  • Read the complete diff and compare its behavior with the requirement.
  • Verify unfamiliar APIs and dependencies against version-matched, authoritative sources.
  • Test boundary cases, failures, authorization, data handling, secrets, and external calls.
  • Review generated tests independently; they may repeat the implementation's mistake.

The submitter owns every line. Set review depth from the change's impact and reversibility, not from how quickly or confidently the code appeared.

What is the "prompt-and-pray" anti-pattern, and what does a healthier workflow look like?

Your answer

Re-explain

Prompt-and-pray means sending a vague request, accepting a large result, and hoping it works without controlling scope or gathering evidence.

  1. Define the goal, relevant context, constraints, non-goals, and acceptance criteria.
  2. Ask for a plan when the work is nontrivial, then correct faulty assumptions.
  3. Make one small, reviewable batch and inspect its complete diff.
  4. Run focused checks before continuing; require approval for risky commands.
  5. Refine the specification or context when results are wrong.

The assistant drafts and explains work. The engineer controls direction, permissions, and the evidence required for acceptance.

How can test-driven development act as guardrails when you delegate coding to an AI agent?

Your answer

Re-explain

Test-driven development gives an agent an executable contract and a short feedback loop, making delegated work narrower and easier to inspect.

  1. Review a test that expresses one required behavior and confirm it fails for the right reason.
  2. Ask for the smallest implementation that makes the test pass.
  3. Protect tests from unapproved edits so the agent cannot weaken the contract.
  4. Add boundaries, invalid inputs, and failure paths, then rerun focused checks.
  5. Inspect the implementation and repeat with the next behavior.

A green suite proves only the specified cases, so human review and broader verification still matter.

What are the most common pitfalls of letting an AI generate your test suite?

Your answer

Re-explain

Generated tests often mirror the implementation instead of the requirement, so a polished suite and high coverage can still provide weak protection.

  • Shared mistake: Code and assertions can encode the same wrong interpretation.
  • Weak signal: Tautologies, excessive mocks, and snapshots may never detect realistic faults.
  • Missing risk: Boundaries, invalid input, permissions, and failure paths are easy to omit.
  • False confidence: Tests may pass even after the behavior they claim to protect is broken.

Start expected outcomes from an independent specification. Review assertions, add integration coverage at important boundaries, and use mutation testing where its cost is justified.

What is a hallucinated API, and how do you catch one before it causes damage?

Your answer

Re-explain

A hallucinated API is an invented method, option, endpoint, or package whose plausible name makes it look real.

  • Let the compiler, type checker, or language server flag unknown symbols.
  • Run a focused experiment in dynamic code instead of trusting an explanation.
  • Check unfamiliar calls in official documentation for the project's installed version.
  • Review a package's registry, publisher, and source before installation; plausible invented names can create supply-chain risk.
  • Keep new dependencies behind human approval.

When sources conflict, trust the executable project and authoritative documentation over the model's confidence.

How does rubber-duck debugging change when the duck can talk back?

Your answer

Re-explain

A talking rubber duck can question assumptions, propose competing hypotheses, and suggest experiments instead of merely forcing you to explain the bug aloud.

Start with observed facts, expected behavior, and one testable hypothesis. Ask the assistant what evidence would distinguish that idea from alternatives, then run the smallest useful experiment.

Guard against anchoring on a fluent story. Share only relevant, redacted logs, and verify claims in code, documentation, or runtime output. The assistant expands the search space; direct observation decides which explanation survives.
