Reflecting on a year of Claude Code

When we first released Claude code, it was like a little video and I remember posting it to Slack and there was like two people that gave like the reaction . Like people were like excited . I thought it was really cool . Especially for my very easy engineering tasks . It was quite good at it . That's like a really nice way to say that it wasn't really good . I can't believe it's only been a year since we first launched in Claude code . It's hard to remember what what that was like. Like it it is it's so different than what we're doing today . Like now I just have like armies of agents that are doing stuff . Like I'm prompting one agent or I have like an agent that's like prompting agents that's prompting agents and it's like a tree of like thousands of agents . But it's I think it's just like the most important idea when working on this stuff is like every single time Claude makes a mistake I don't tell Claude to do a different way . I tell it to write it to the Claude MD or to like make a skill or or . And if you can do this then Claude can just like run forever . And I I think the other thing that we kind of realized is the verification is really important . Like we didn't realize that . I hear this come up a lot with developers and enterprises that we meet with . Um what are your tips for making a really good making Claude code really good at verification? I sort of feel like this is this thing that just like everyone misunderstands cuz whenever we talk about verification people are thinking like unit tests or they're thinking like lint or like type check . These are the things that are obviously really easy to automate and these are the things that were already automated. But actually when we talk about verification for agents it's something slightly different . It's like can the agent run the thing ? It takes a little bit of uh mental work to figure out how exactly do you do this cuz it's often not straightforward. And I think that's like that that's one of the challenges . I remember with uh with Opus 4 Claude tested itself . And we we we just like hooked it up to Opus 4 and I was
