Software Engineering

AI-driven edge case discovery

Uses Claude (Opus-4.6) to review API/flow/PR context and propose edge cases (retries, timeouts, caching, permissions, unusual inputs) to strengthen implementation and testing.

Why the human is still essential here

The engineer validates relevance, prioritizes scenarios, and decides what to implement/test; AI accelerates brainstorming and coverage.

How people use this

API edge-case checklist

AI takes an endpoint spec and produces a categorized checklist of edge cases (auth, pagination, idempotency, rate limits, invalid payloads) to test.

Concurrency and retry scenarios

AI proposes race conditions, retry storms, and ordering issues based on the flow description so the engineer can add guards and tests.

Property-based test ideas

AI suggests invariants and input generators to expand coverage beyond hand-written examples in unit tests.

My top AI tools for planning, edge cases, and PR reviews

In my previous post I listed the top 5 things I use AI for apart from writing code.
Reena Garg asked which AI tools I use for these tasks 🙏 — sharing my list👇


⭐️ Thinking partner for ideas Tool: Cursor (Plan/Ask mode) I use Plan mode to discuss a feature/design: “what am I missing?”, “what can go wrong?”, “what’s the simplest version?”, “how should I break this into steps?”, “How can we implement this?”,


⭐️ Finding edge cases Tool: Claude (Opus-4.6) I paste the context (API, flow, PR description) and ask it to list edge cases: retries, timeouts, caching, permissions, weird inputs, etc. Opus works great for any code related tasks.


⭐️ Code review before the code review Tool: CodeRabbit, GitHub Copilot, Cursor Review These tools are really great to get a review before asking for a human review. I use them on all of my PRs.


⭐️ Turning manual processes into clean steps Tool: ChatGPT / Claude This is usually a back-and-forth conversation until it becomes a clean checklist/runbook and sometimes an automation script.


⭐️ Writing clearer communication Tool: Any AI works, but I mostly use ChatGPT PR descriptions, Slack updates, incident notes — it helps turn messy thoughts into clear writing.


If you’re using any AI tools in a different way, please share — I’d love to learn and try them too 🙌
