I work for a $50B+ company (is this big tech? idk), but I’ll answer this because we are fully embracing AI (Cursor, Claude Code, cloud agents, AI reviews, you name it)

> Have you noticed faster pace of development?

Yes, our org has had a 50% increase in PRs since Opus 4.5 released.

> Have you seen changes to code quality or code review?

Yes, significantly more bugs (no exact number), but consider it maybe 3-4x in volume. However, nothing catastrophic and everyone just uses AI for fast-follow fixes anyways. The company as a whole is embracing this style of development for better or worse.

> Do teammates that use these tools complete sprint tasks faster than those who don't?

Yes, but my entire team uses them. I’d say the ones who use it more effectively (crazy skill setups, better tooling/commands, better scaffolding) finish much faster. Probably 80% of my team still uses Cursor in the one-shot way with very vague requirements, and don’t have the AI connected to github, jira, slack, etc which can actually feed really important context into decision making.

If I do something more than once a day, I write a custom slash command for it. This has personally 2x’d my pace.
