Everything Fiona Fung said on any show that made the record, most notable first. Each card names its show and opens the statement there.
AI tools have eliminated raw coding as the primary software engineering bottleneck
“And that's the shift that, you know, like we're seeing with cloud code and coworkers is Coding is no longer the bottleneck.”
Entire Claude Code team checks in code, including PMs and designers
“Like now, not only engineers with, we also have designers, PMs, everybody on the Clark code team checks in code.”
Fung manages engineers via Claude sessions connected to all repos and Slack
“The other shift that I've recently done is I actually have a quad code remote session that I enlist in all of our repos. And so this way I have full visibility into the work that everybody's doing. And this instance, he also has access to all our Slack channel…”
Anthropic engineers use a swear word dashboard to track user frustration
“That was an engineer on the team of, hey, we should maybe track square words. I'm like, oh, that's a great idea. I remember it. I had just, you know, joined when we were having that really fun conversation. Yeah, so it's again, like, it's very interesting to k…”
Fung: Engineering managers should start as ICs before managing people
“On the manager front, I think giving time for managers that join to be able to go deep and to do that before supporting people. And then they actually like end up building really great rapport with the team. Like, because if not, I think sometimes as managers,…”
Anthropic engineers felt isolated working with AI, prompting pairwise programming lunches
“The other thing that we found interesting on the Cloud Code team is after a while we felt it could start being a lonely experience cause we all started just working with our agents so much. So recently we started maybe like a pairwise programming lunch.”
Product managers are no longer bottlenecked by engineering bandwidth
“PM are no longer bottlenecked of if they have an idea waiting on engineering bandwidth.”
Most engineering commits at Anthropic are now Claude-assisted
“Well, definitely. I think most commits are Claude assisted.”
Fung: AI allows smaller mobile teams while retaining deep platform experts
“Like, it's really important to still bring on folks with those expertise, but we probably don't need like as large because people are flexing.”
Check specs into repositories so AI reviews can enforce coding standards
“Any time you have like a statement of what good looks like. Get that into the repo, and then code review can make sure it's still matching what you set up to do.”
Fung: AI engineering teams must continue hiring deep subject matter experts
“Whatever are the parts that it's all about trust, but verify the models are really good, but there are definitely a lot of areas that still need You know, the verification. And so wherever you need the deep subject matter expertise, I would say that's, you kno…”
Fung: AI adoption divide will widen without active knowledge sharing
“Cause I just want to make sure we keep sharing the knowledge and, you know, making the tool equitable. Cause if not, I'm concerned that the divide grows larger and larger.”
Software engineering will shift toward managing asynchronous AI agent routines
“So I think we'll, we'll move more towards that kind of like asynchronous style of working.”
Measuring AI tool usage tracks developer motion rather than actual business progress
“There was another saying, I really like don't forsake motion for progress. Because if you're measuring like, you know, like tool user usage, then you're measuring the action, but is it really making whatever the end outcome of yours like important?”
Categorize user issues as 'bad' (irrecoverable) versus 'sad' (recoverable friction)
“Bad is like a very bad, irrecoverable error. And sad is something that's kind of like a pain point recoverable, but it's interesting when you stack up sads, it could, you know, generally go to bad, but even having a, like starting with a high level framework l…”
Fung: Engineers Must Continue Learning Their Underlying Architecture and Dependencies
“I actually still think, understand, like, it's always double clicking on that layer that you depend on. Like maybe that to me is a matter, like it's always take that time to learn about your dependencies. Cause this way, when your dependencies change, like you…”
Fung: Dogfooding prevents leaders from relying solely on metrics and dashboards
“And so I think it's number one, like making, that's how you keep your pulse on the product that you're building and don't get too lost in metrics and dashboards only or presentations.”
Asynchronous AI routines create heavy context-switching overhead for developers
“I think because with routines and everything being more async, I think there is starting to be a high load on our context switching.”
Fung: Engineers should regularly revisit previously failed AI automations
“There might've been something I tried to automate that Claude wasn't quite good enough. And then actually in the next model, oh, well now it is good enough. So it's always also thinking about what may have not worked. Like it might be worth the time to revisit…”
Anthropic replaced six-month roadmaps with lightweight, monthly just-in-time planning
“I think six months was too long. So now for sure some projects will take more than a month, but we try to do like a month planning, like really lightweight. Actually, there's not even dots. It's really just Also hunting on a little spreadsheet of what we think…”
Fung uses automated Claude routines to draft summaries and PRs overnight
“Like now I just have a routine that automates all this for me. And then there's also, it's almost like before I would, you know, be able to kind of like, you know, generate some prompts, but now with routines, it's almost like I'm, you know, having an agent he…”
Human reviewers were a major engineering bottleneck before Claude code reviews
“I think we didn't even have cloud code reviews last year. And so speaking of bottlenecks, that, that was a really, really big bottleneck of, you know, the human reviewers.”
Fung: Claude Code initially lacked engineers with distributed systems expertise
“When I first joined Cloud Code, we had really great kind of like product generalists. And then I realized, oh, we were missing folks with a systems background. And so that was definitely an area that we needed more folks with kind of like systems and distribut…”
Fung: Leaders driving AI adoption should focus listening tours on senior engineers
“Outside of metrics, especially if on teams, as you're having more people adopt AI tooling, I would say definitely go on a listening tour for the leaders listening to a podcast, especially, you know I love to focus on the senior engineers as well. Like hear fro…”
