SLIDE 1 — Cover

Headline: 920 tests, 0 failures. Here’s what AI pair programming actually looks like on a real production feature.

Sub-line: Not autocomplete on steroids. The more significant benefit is different — and harder to explain.

SLIDE 2

Label: THE REAL VALUE

Headline: AI pair programming raises the quality floor. It’s not about writing code faster.

Body: The bigger impact is what happens between writing and shipping — the discipline that gets skipped when humans feel time pressure. AI doesn’t feel time pressure.

SLIDE 3

Label: THE PROCESS

Headline: Brainstorm → spec → implementation plan → subagent execution → two-stage review.

Body: Each step has a clear gate. Nothing is implemented until the spec is approved. Each task is executed by a fresh subagent with exactly the context it needs — no accumulated drift.

SLIDE 4

Label: THE TDD LOOP

Headline: Write the failing test first. Confirm it fails for the right reason. Then implement.

Body: Human developers skip step 2 (“I know why it’ll fail”). AI doesn’t. The discipline holds even when it’s tedious. For the ConnectorFactory alone: 7 tests written before a single line of implementation.

SLIDE 5

Label: REVIEW STAGE 1

Headline: Spec compliance: did it build what was designed?

Body: A fresh agent reads the implementation line-by-line against the spec. On the GCP get_claim_status() implementation: everything was correct, but the credential fallback path had no test. Added before merge.

SLIDE 6

Label: REVIEW STAGE 2

Headline: Code quality: the “assisted” status bug — wrong semantics, no crash.

Body: file_claim() can legitimately return {"status": "assisted"}. Initial code treated it as an error, logging a misleading warning. Not a crash. Would have appeared as confusing log output months later.

SLIDE 7

Label: THE INSIGHT

Headline: Spec compliance review is more valuable than code quality review.

Body: Quality review surfaces issues that’ll matter in 6 months. Spec compliance surfaces issues that would have made the feature incomplete on day one. Don’t skip either.

SLIDE 8

Label: WHAT IT DOESN’T REPLACE

Headline: Architecture decisions, domain judgment, and customer empathy remain human.

Body: When the quality reviewer flagged a DRY violation, it was technically correct. We looked at the codebase history and accepted it as intentional tech debt. That judgment required context no AI had.

SLIDE 9

Label: FRESH CONTEXT

Headline: One subagent per task. No accumulated context drift.

Body: “I think we decided X three tasks ago” doesn’t happen when each task starts fresh. The spec is the source of truth — not a growing conversation history.

SLIDE 10 — CTA

Headline: Want the full story?

Body: The full breakdown: the TDD loop, the two-stage review, the bugs that almost shipped, and what AI pair programming doesn’t replace.
