A garden grows from what it reads. These are the external pieces that earned a place in my thinking — each one read properly, kept because it changed how I work or think, and annotated with why. Added in occasional batches, not as a feed.

Effective Harnesses for Long-Running Agents
Anthropic
The clearest statement that continuity across sessions is an architecture problem, not a prompt problem.
-
Dynamic Context Discovery
Cursor
Pull over push for agent context: give the agent less and let it retrieve, with files as the universal primitive.
-
Files Are All You Need
LlamaIndex
Files quietly won as the central abstraction for agent memory, retrieval, and skills, displacing heavier machinery.
-
Context Engineering
Harrison Chase on the Sequoia podcast
When behaviour emerges from code plus model, traces replace source files as the debugging surface.
-
Notes on Claude Coding
Andrej Karpathy
The 80/20 flip in weeks, and the observation that model failure is now conceptual rather than syntactic: hasty-junior mistakes, not syntax errors.
-
Outsource Thinking, Not Understanding
Andrej Karpathy
The line worth keeping between what you delegate to a model and what you must still hold yourself.
-
Shipping at Inference Speed
Peter Steinberger
What development looks like once the bottleneck is inference time rather than code: parallel projects, output streams monitored rather than read.
-
How to Work and Compound with AI
Eugene Yan
AI work compounds only when artefacts, decisions, and corrections persist as context for future sessions; the essay behind a lot of how this site’s author works.
-
How is Linear so fast?
performance.dev
Local-first sync as a worked example of an architecture bet paying off in feel, not just benchmarks.
Thinking and positioning
-
Get to the Core of the Thing
Shreyas Doshi
High-altitude binaries create the appearance of strategy while keeping the room away from the hard customer-specific question.
-
How to Enter Side Doors
Maja Media
A job is a bundle of problems someone wants solved, not an object on a board; the best career reframe of the year.
-
What Personal Software Actually Is
Dan Shipper
Personal software as software shaped by one person’s judgment rather than a market’s average need.
-
Think Inside the Box
Cal Newport
The disciplined counterweight to AI maximalism: constrain the tool to the box where it demonstrably helps.
AI and the economy
-
2026: This is AGI
Sequoia
AGI defined pragmatically as the ability to figure things out, with the three ingredients already shipped.
-
AI in Investment Management, 2026 Outlook
Two Sigma
Organisational integration beats raw model power; institutional capability is the differentiator, not model choice.
-
Anthropic Economic Index
Anthropic
Complex tasks see larger AI speedups than simple ones, inverting the usual displacement narrative.
-
After Automation
Dan Shipper, Every
Benchmarks measure a model operating inside a frame humans supplied; as framed competence gets cheap, the human work moves to problem-definition, review, and exceptions.
-
The 2028 Global Intelligence Crisis
Citrini Research
A scenario, not a forecast: what happens if AI succeeds and the economy’s redeployment loop breaks anyway.
-
How to Build a Self-Improving Company with AI
Tom Blomfield, Y Combinator
The organisational thesis: repeated work rebuilt as governed feedback loops, with humans kept at the high-stakes edges.
-
The Self-Driving Company
Amjad Masad, Replit
A first-person field report of company-wide agent adoption; the numbers are self-reported and unaudited, but the shape of the operating model is worth reading anyway.
