The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 14 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Ball: Amp core team has 8 people, ships 15 times daily without code reviews
“I think we're around eight people now on the AMP core team, and we still don't do formal code reviews. We still push to main. We still ship 15 times every day.”
Ball: Complex sub-agent workflows will result in user hangovers
“A lot of the features what we see, you know, where people build like elaborate workflows, like I have my custom slash commands and they trigger custom Custom sub-agents and they in turn trigger custom MCP tool calls behind which again another model is doing in…”
Ball: AI coding tools must optimize harness and scaffolding per model
“And people are now also waking up to the fact that it's not just the model, it's the system prompt, it's the tools, it's the harness. The scaffolding around the model. So I can give you the choice to use Gemini 2.5 in, in AMP, but without the system prompting …”
Ball: Foundation models will become background implementation details in AI tools
“So I think we're going towards a future where the model will become an implementation detail to some sense, and we will end up on a different abstraction layer.”
Ball: Coding agents should outsource typing, not engineering thinking
“The failure mode of outsourcing the thinking, but not the typing, which I think it should be the opposite. You still have to know engineering. You still have to know how to program. You still have to know your application and its architecture, how it's deploye…”
Ball: Custom MCP tools fail if workflows diverge from frontier training
“If I give it this other custom-made MCP that we built internally, and our processes don't map to anything that OpenAI and Anthropic have seen or trained for, it won't be used, and you won't get good results.”
Ball: Developers are actively modifying codebases to suit AI agents
“What we're seeing now with agents is as soon as somebody has seen what it can do, they have such a multiplying effect or this brings so much value that people are willing to adopt the code base for this. Like the first time in how many decades where people are…”
Ball: The Sourcegraph Amp team does not use formal evals
“I think we don't have any set evals. We don't. And this was controversial up until a week ago, I think, when I think Boris from
Or two weeks ago from Anthropix that they don't have evals for the coding agent too.
But we don't, and we haven't had them.”
Ball: Engineers under 25 find the terminal dated, preferring editor AI
“There's also a generational divide where I would say the younger people, you know, younger than 25, their terminal seems old to them and they were much more inclined to use the stuff in the editor.”
Ball: Agent scaffolding should be disposable as foundation models improve
“You want to build a scaffolding around the model, a wooden scaffolding that if the model gets better or you have to switch it out, the scaffolding falls away. You know, like the bitter lesson, like embrace that a lot of stuff might fall into the model as soon …”
Ball: Unify and make logs verbose for AI agents, not human readers
“Instead of having the client log and having the browser log and having the database log, let's have one unified log, because then it's easier for the agent to just look at this log and make sense of it. And then it turns out it doesn't have to be nicely format…”
Ball: Web frameworks will integrate AI agents directly into the runtime
“What if the agent is integrated into the framework so that you can, if the application fails to run, you can ask the agent that has access to all of the context. And that's going to be more and more, I think like a lot of the, you know, developers will build s…”
Ball: Engineers lacking business and product taste will lose value
“Like as an engineer, you cannot see yourself as the person anymore who types out a spec or turns a product PRD into code. I think you need to be aware of business. You need to be aware of a product. You need to know and have some taste for software. Otherwise,…”
