  Claude Code for fell running

  

  I’ve got a big run coming up, and I want to be prepared, so I created a GPX file to load onto my watch so that I can follow a little red line across the Yorkshire Dales.

  A little red line alone is a big help, but a bigger help would be to have the checkpoints on the watch as well, so that when it’s been dark for hours and I’m stumbling through peat hags, I can know that I’m only 2 km away from Capplestone Gate. Or whatever.

  The problem is that manually adding checkpoints to a GPX file is a tedious prospect in Garmin Connect. The solution is that I have a monthly subscription to the Do Tedious Things For Me robot.

  

  Claude Code made short work of the GPX file: I pasted in a screenshot from the event handbook listing the OS grid references for each of the checkpoints, and it parsed those checkpoints first into a CSV and then interpolated them into the GPX file itself. Names and lng/lats, and, with a little further prompting, elevations for each of the waypoints.

  I uploaded this file to Garmin Connect but found that some of the waypoints were missing; Claude discovered that the grid references provided (to 100m precision) weren’t always exactly on the plotted route. It tweaked the file; I reuploaded: success.

  The code agent orchestra - Addi Osmani

  I usually think that Addi is pretty clever, and it’s clear that he really knows his stuff — and it’s cool that all of these tools and methodologies exist, but I can’t help but think that this is not useful at all.

  The parent orchestrator only talks to two agents, keeping its context clean. Feature Lead A gets a brief like "Build the search feature" and decomposes it into Data, Logic, and API subagents on its own. The parent never sees those details.

  This doesn’t solve any of my problems, which all pertain to expertise, complexity management, and deep knowledge of systems. Whereas a lot of these breathless AI accelerationist thoughtpieces basically assume that everyone is just trying to build the same greenfield project management applications, over and over, all of the time.

  "Build a reusable card component." "Integrate with this API." "Build the search feature." What if the search feature was already built, 8 years ago, by someone who has dropped off the face of the earth, and for some reason stopped working earlier this week?

  I’d like to think that I’m reasonably bullish about using AI for programming — I’ve had some success with using Claude to increase the pace of development at work — but this just looks like it generates heaps of new code that no one knows how to understand, not even the agents themselves.

  Karpathy on Claude Code

  Yes I have been Claude Code-ing a bunch, so instead of telling you what I think, here's my commentary on what someone a lot smarter than me thinks.

  Fun. I didn't anticipate that with agents programming feels *more* fun because a lot of the fill in the blanks drudgery is removed and what remains is the creative part.

  But:

  Atrophy. I've already noticed that I am slowly starting to atrophy my ability to write code manually. Generation (writing code) and discrimination (reading code) are different capabilities in the brain.

  Using Claude Code to write code is like learning a language by reading alone. Being able to read signs in a foreign language doesn't mean that you're fluent... but a lot of the time it's sufficient.

  So much of what makes me a good coder is only doable when I’m down in the code itself, manually moving things around to build a legible API.

  And worse:

  Slopacolypse. I am bracing for 2026 as the year of the slopacolypse across all of github, substack, arxiv, X/instagram, and generally all digital media. We're also going to see a lot more AI hype productivity theater (is that even possible?), on the side of actual, real improvements.

  You thought that JavaScript fatigue was bad — I can feel a serious backlash building in 2027.
