- Observing the Changescape
Engineers must adopt new 'changescape' tools to grasp large-scale code changes in AI-assisted development, moving beyond line-level diff reviews toward holistic system evolution understanding.
- If AI coding is lowering your code quality, you’re not managing quality right
With layered quality practices like spec-driven development and AI-assisted testing, coding agents can double output without increasing bugs.
- The Evolution of the Agent Harness - by Dan McAteer
The article argues that as AI models internalize agent harness capabilities, the remaining harness evolves into an interface for managing scarce human attention rather than directing model behavior.
- The cost of caring about software - Alex Rios Substack
AI reduces code-writing effort but shifts verification cost onto reviewers, creating an externality where comprehension debt rises despite faster generation.
- The 33-year-old executive Satya Nadella is trusting to save Microsoft’s AI strategy
Microsoft is betting on rising executive Jacob Andreou to retool its Copilot AI product and regain competitiveness against rivals like OpenAI and Anthropic.
- agent-skills/skills/autoreview/SKILL.md at main · openclaw/agent-skills
The piece defines a structured pre-commit code review skill for AI agents, specifying contracts, scope governance, and engine isolation across multiple review engines including Codex, Claude, and others.
- What are you doing this week?
A developer finds that large coding agents like Opus 4.7 harm the programmer's mental model, preferring smaller models and old-style FIM autocompletion.
- lil agents — tiny AI friends for your Mac
lil agents places animated AI companions on the macOS dock, each with a Claude session for chatting and coding.
- Why your next mobile app is probably headless - Tuan-Anh Tran
As AI assistants answer queries and complete tasks without opening vendor apps, mobile apps become headless backends, and metrics like traffic and sessions decline long before installs.
- Microsoft’s New AI Health Tool Can Read Your Medical Records and Give Advice - WSJ
Microsoft launches Copilot Health, an AI-powered concierge doctor within its Copilot app that provides personalized advice based on user medical records and biometric data.
- The Singularity will occur on a Tuesday
A satirical article fits hyperbolic curves to five AI metrics and predicts the singularity will occur on a specific Tuesday, critiquing the hype and social dynamics around the concept.
- Stop generating, start thinking
Hacker News commenters debate whether AI coding agents are genuinely useful or overhyped, with critics citing prompt engineering burdens and proponents citing successful agentic workflows.
- Microsoft’s Pivotal AI Product Is Running Into Big Problems - WSJ
Microsoft's Copilot chatbot struggles with brand confusion and low enterprise adoption as its OpenAI partnership wanes.
- There is an AI code review bubble
The Hacker News discussion argues that the AI code review market is a bubble, with many tools failing to differentiate or provide meaningful value beyond linters.
- Microsoft Office renamed to “Microsoft 365 Copilot app”
Microsoft rebranded the Office app to "Microsoft 365 Copilot app," drawing widespread criticism for confusing naming and perceived desperation to boost AI usage.
- Build Software. Build Users
Quality software requires understanding users deeply, so the author proposes building agentic user simulations before coding—then iterating between user and software development.
- The changing drivers of LLM adoption
LLM adoption remains on trend globally, but growth is increasingly driven by international markets, app usage, and bottom-up workplace adoption rather than US consumer growth.
- Microsoft increases Office 365 and Microsoft 365 license prices
Microsoft is raising Office 365 and Microsoft 365 license prices effective July 1, 2026, justifying the increase with new AI features like Copilot.
- Microsoft has a problem: lack of demand for its AI products
Microsoft's AI products suffer from poor quality and low demand, driven by forced integration into core tools rather than genuine user need.
- Microsoft drops AI sales targets in half after salespeople miss their quotas
Microsoft lowered sales growth targets for AI agent products after salespeople missed quotas, signaling enterprise customer resistance.
- Don't push AI down our throats
Hacker News commenters argue that aggressive AI promotion by big tech is driven by investor pressure, not user demand, forcing unwanted tools on users.
Takes
Really nice walk-through of Omarchy by Microsoft's Dan Wahlin. Super cool to see him use Copilot for all his agentic alterations! Omarchy supports every major harness right out of the box. (Now can we talk bringing Office to Omarchy, @satyanadella 😄?)
@dhh
Here’s what I’d do if I was in charge of GitHub, in order: 1. Establish a North Star plan around being critical infrastructure for agentic code lifecycles and determine a set of ways to measure that. 2. Fire everyone who works on or advocates for copilot and shut it down. It’s not about the people, Im sure theres many talented people, youre just working at the wrong company. 3. Buy Pierre and launch agentic repo hosting as the first agentic product. Repos would be separate from the legacy web product to start since they’re likely burdened with legacy cross product interactions. 4. Re-evaluate all product lines and initiatives against the new North Star. I suspect 50% get cut (to make room for different ones). The big idea is all agentic interactions should critically rely on GitHub APIs. Code review should be agentic but the labs should be building that into GH (not bolted in through GHA like today, real first class platform primitives). GH should absolutely launch an agent chat primitive, agent mailboxes are obviously good. Etc. GH should be a platform and not an agent itself. This is going to be very obviously lacking since I only have external ideas to work off of and have no idea how GitHub internals are working, what their KPIs are or what North Star they define, etc. But, with imperfect information, this is what I’d do.
