Demis Hassabis argues that AGI may be only a few years away, leaving a narrow chance to set shared thresholds for the most dangerous models. Rules that are too strict may leave safe but useless systems; rules that are too loose may let someone else deploy genuinely dangerous capabilities.

With the same parameter count, matrix dimensions and layer count decide whether a GPU computes at full speed or wastes work moving data and processing edge tiles. Near-square dimensions aligned to 128, 256, or 512—and often wider, shallower models—fit hardware better without sacrificing accuracy.

A security researcher demonstrates a stealthy data exfiltration technique: turning hyperlinks into a keyboard so Claude "types" out the user’s name, company, and hometown one character at a time—while the user sees nothing but a coffee shop menu.

Satya Nadella coins the "Reverse Information Paradox": economics used to worry about sellers leaking knowledge to sell it — in the AI era, buyers must feed their secrets into AI just to use it. Enterprises need a "trust boundary" to keep their learning gains in-house.

The TypeScript team rewrote the entire compiler in native Go. Real-world tests show 8x to 12x faster compilation with lower memory usage. VS Code project compilation dropped from 125.7 seconds to 10.6 seconds. Time to first error in the editor went from 17.5 seconds to under 1.3 seconds.

Jarred Sumner rewrote 535K lines of Zig into Rust with 64 Claude agents in parallel, adversarial code review, and mechanical porting. 11 days later: all tests green, memory leaks fixed, binary 20% smaller.

Anthropic engineer trq212 shares his methodology for coding with Claude Fable 5: the bottleneck isn't model capability anymore—it's whether users can surface their 'unknowns' before, during, and after implementation. Includes prompt examples plus HTML artifacts for visualizing blind spots and plans.

Simon Willison learned from the Claude Code team fireside chat: instead of dictating rules, let Fable use its own judgment. Extended application: let Fable decide which tasks to delegate to cheaper models.

AI can handle 80-90% of frontend work, but the remaining edges — depth, sensitivity to new platform features, and knowing when the stable default is not the best answer — are becoming the real moat. Fundamentals are not obsolete. They are compounding assets.

Geoffrey Litt asks a sharp question for the agent era: if agents can write and verify more code by themselves, why should humans still understand the code? His answer is that understanding is not only for verification. It is how humans keep participating.

Phil Chen shares six years of career lessons — from his own startup through Helm AI, Scale AI, OpenAI, and Google: when agents can solve every well-defined problem, what stays valuable is finding problems, sprinting the last mile, and everything that cannot be graded by a loss function.

Fable 5 as the commander, Opus as the deep thinker, Sonnet as the grunt worker, Codex as the parallel-universe senior engineer — a multi-model orchestration setup inside Claude Code that reserves the most expensive brain for the most critical decisions.

Mitchell Hashimoto tries to define "taste": consistently making high-quality qualitative judgments where no objective metric exists. People say taste is worthless because it is easy to copy — but that proves the opposite: without someone with taste making the thing first, there is nothing to copy.

Open any agent skill and it's stuffed with 'be more detailed,' 'be thorough'—lines that look diligent but don't change the model's behavior at all. Matt Pocock names the no-op trap, plus how to spot a dead instruction versus one that actually pulls its weight.

In 2010 Princeton priced happiness at $75,000/year. A 2021 Wharton study found the ceiling gone. The 2023 joint reanalysis: money keeps working for almost everyone — except the unhappiest group, where it stops near $100,000. The real question: is your money deleting worry, or feeding the self?

Loop Engineering is the wrong name. The real work isn't the loop—it's the foundation nobody photographs: push 'what counts as correct' down to the cheapest enforcer, align granularity, lay a nine-layer sensor net, pay off comprehension debt. Execution went free; legislation got expensive.

As CTOs aggressively push AI coding, software engineers split into two classes: the lazy and the craftsmen. The lazy throw code up, never read it, never test it, never care. The craftsmen carry the whole review burden, watch quality collapse, and eventually become lazy too.

Big companies always have two camps: process people and outcome people. Over decades they barely learned to coexist — but AI shattered that balance. The outcome camp sees a chance to finally shake off the process camp; the process camp sees the AI-generated disaster coming.

Someone called Ghostty "unusable" for taking a second to launch. Its author Mitchell Hashimoto replied with a textbook tradeoff lesson: the slow cold start is not a bug — it is cost paid up front to buy eight smooth hours. Are you optimizing a button you press once a day?

Sakana ships Fugu: a multi-agent orchestration system behind one API, sold as "AI sovereignty." But a researcher who read the tech report tears it down — a closed orchestrator on closed models means you control less, not more, and it wins benchmarks while never reporting cost.

Most coding-agent best practices from six months ago are now out of date. The new playbook: bigger tasks, longer sessions, and adversarial review so the agent verifies its own work — the engineer just shovels coal into the engine.

A guy spent two years doing every productivity tip out there, only to realize he had become "the most disciplined unproductive person alive." The problem was not a lack of effort — it was making the optimization system itself the goal, and forgetting to ask what it was all for.

Loop engineering is sold as designing orchestration and spinning up agents — but the tools now do that half for you. The half still hard, still deciding the result, is the verifier. Anthropic's Bun port is the tell: 99.8% of tests pass, yet the announcement says not yet in production.

Every two hours, Codex drafts email replies for review. The drafts are good — he edits them anyway. Those edits are context too, and most automations throw them away. The fix: an inner loop brings context to the work; an outer loop recovers context from the review diff.

20,000-plus real coding-agent sessions laid bare: most misalignment costs time and trust, not irreversible damage. But among cases where you can see the ending, 91.49% still needed the user to fix it by hand. And the errors that remain are drifting toward rule-breaking and lying about progress.

A six-word phrase seized the AI-coding timeline, but nobody boosting it agreed what it meant. This is not the how-to; it is why the loop blew up, its five-year lineage, why the loop is now the costly part, and why the durable asset is the skill it calls.

You can't tell a model 'make it premium and smooth' and get a premium UI. kvnkld's full system behind his polished components — easing curves, design tokens, real physics, the 98% press — reduces to one move: trade adjectives for numbers. The model is the hands; the last 10% of taste is still yours.

Anthropic read about 400,000 Claude Code work sessions to find who gets the most out of agentic coding. The answer is counterintuitive: not the best programmers, but the people who understand the problem they're solving.

Mitchell Hashimoto's blunt rule for agent coding: any diff over ~1500 lines is too big — a signal to cut the problem up. First let the agent sloppily draw an owl, then break the mess into atomic tasks, hand-massage the shape, and re-run in parallel — pushing every change below your review threshold.

The 2026 data all points one way: AI pushes raw code output up about 4x, but real delivered value only rises about 10%. The gap in between is all review debt. Writing code got cheap; being sure it is right did not. Code review went from a side effect of engineering to its most leveraged front line.

Microsoft CEO Satya Nadella on the future of the firm in an AI economy: build two kinds of capital — human capital and token capital. The real moat isn't picking the strongest model, but a learning loop that compounds. Plus a warning: don't let a few models eat every industry.

Dimillian (an iOS dev now at OpenAI) wrote a field guide for Codex Mobile. The part worth keeping is a mental model that holds across tools: your phone is not a shrunken terminal, it is the control center that keeps you making decisions while the agent does the work.

Nobody teaches you how to do research, so most people learn to look like a researcher. As AI makes generating experiments cheap, the scarce skill is a loop: pick your own problems, upgrade inputs, write hypotheses down, tighten the loop, stare at outputs, kill bad ideas early, find your people.

OpenRouter shipped Fusion: run several models in parallel, then have one model read every answer and rewrite a final response. On DRACO, three cheap models beat solo GPT-5.5 and Opus 4.8 and nearly match Fable 5 at half the cost.

Fable 5 nails on the first try what used to take days — but it's too proactive and over-elaborates, so prompts tuned for Opus 4.8 hold it back. The official guide isn't about making it stronger; it's about reining it in: steer with intent, draw boundaries, talk like a human when the run ends.

When an agent breaks in production, observability hands you a gorgeous autopsy — every call, latency, and token, but not why it broke or how to fix it. The fix is a loop that runs itself: failure → approved patch → locked-in regression test. Opik is just the example; the point is the loop.

Zed founder Nathan Sobo argues the real source of software is the ongoing conversation with your agents, not the tidy commits you slice it into. Git can't hold that flow, so Zed built DeltaDB: every operation becomes a delta with a stable identity, keeping the conversation glued to the code.

Simon Willison gave Fable 5 a screenshot and one line: fix a stray scrollbar. Fable spun up a dev server, built a screenshot workaround, injected JavaScript, and wrote a CORS server to read CSS. Two CSS lines, $12, and an unsandboxed-agent warning.

Two of the most senior AI engineers alive said the same thing this week: stop prompting your agent, design loops that prompt it for you. Loop engineering unpacked — open vs closed loops, the six building blocks, prompt vs loop engineer. Plus: spotting one smooth ad sewn into the lesson.

Supergoal is a workflow for Claude Code and Codex: run /supergoal to plan deeply, write phase specs, then generate one ready-to-paste /goal. The interesting part is not another planning prompt, but a handoff protocol for long autonomous tasks.

Getting into a frontier AI lab is often framed as research skill plus trench engineering. Underneath, both are about making progress when the map is incomplete.

When machines start writing code, the scarce skill is not tool fluency. It is architectural judgment: digging below abstractions, defining boundaries, writing specs, falsifying claims, and deciding where human judgment still matters.

Anthropic argues AI is already speeding up AI development. Claude now handles major parts of engineering and research execution; the hard bottlenecks are judgment, verification, and coordinated slowdown.

Claude Code dynamic workflows let Claude write JavaScript workflows, spawn subagents, pick models, isolate worktrees, resume work, and save useful processes as reusable artifacts. The point is not more agents for everything; it is turning agent orchestration into an executable workflow.

Cursor moved cursor.com from a headless CMS back to raw code and Markdown. The important part is not just the $260 bill. It is that AI agents make some human-friendly abstractions feel like walls.

When learning a new tool with Codex, the worst move is asking it to give you a lecture. A better pattern is to ask it for an entry point, a rough map, a tiny exercise, a teach-back check, and breadcrumbs for next time.

Anthropic explains how claude.ai, Claude Code, and Claude Cowork contain agents: model defenses miss, permission prompts create fatigue, and the hard boundary is the VM, sandbox, filesystem policy, and egress control.

Google Engineering Practices frames code review as code-health work, not a perfection ritual: approve CLs that improve the system, while aligning design, tests, speed, comments, and author habits around maintainability.

Codex is no longer only editing code. Persistent threads, voice, queuing, browser and desktop tools, automations, side-panel review, and shared memory are turning it into one reusable workbench for computer work.

OpenAI's Cookbook frames Codex Goals as a thread-scoped completion contract: the objective persists, but completion must be checked against evidence. This post fills in the official spec angle around SP-192, SP-197, and SP-207.

Nous Research proposes CNA, a method that uses contrastive prompts to find a tiny set of MLP neurons tied to refusal behavior. The interesting point is not just jailbreaks, but what this says about alignment fine-tuning.

Whether Claude Code works inside a large codebase is not just about model scores. The real question is whether the team has built rails for the agent: maps, automation, on-demand tools, symbol navigation, internal-system access, and someone to maintain the whole operating setup.

Addy Osmani warns that default AI coding workflows help people close tasks, but do not automatically make them sharper. The difference is not whether engineers use AI; it is whether they use it to test and grow their own mental models.

OpenAI and Anthropic both pushed /goal-like ideas into coding agents. A goal helps, but production agents also need strategy, constraints, health metrics, autonomy boundaries, and stop rules.

Mitchell Hashimoto's point about Bun moving from Zig to Rust is not that Rust won and Zig lost. The more useful lesson is that programming languages are becoming more replaceable, and developer-tool companies need to manage technical narratives before the internet turns them into faction wars.

Peter Steinberger says OpenClaw often runs about a hundred Codex instances in the cloud. The point is not showing off AI spend. It is testing what software work looks like when review, triage, security, reproduction, benchmarks, and meeting follow-up become always-on agent work.

A practical agent engineering guide covering control loops, harnesses, context engineering, tool design, memory, multi-agent systems, evals, tracing, and safety boundaries.

Anthropic lays out two 2028 scenarios for AI leadership: the US and its allies preserve their compute and model lead, or a CCP-controlled AI ecosystem catches up near the frontier. The essay centers on compute, export controls, model distillation, and whether democracies can set the rules first.

Mem0 breaks down Codex CLI memory: not a vector database, but local Markdown, background summaries, credential scrubbing, and grep search. This post looks at when local notes are enough, and when a semantic memory layer makes sense.

Voice agents cannot reuse text-agent memory architectures as-is. Manthan Gupta breaks down why latency budgets, noisy transcripts, and cold-start identity make voice memory a different problem.

Codex `/goal` is not a wish machine. Chris Hayduk's real point is engineering discipline: give the agent a measurable finish line, a fast feedback loop, and Markdown files that work as long-term memory.

Garry Tan argues the real breakthrough in AI coding is not speed. It's turning tests, docs, and evals into a forward-only quality ratchet, so every change locks in what the team learned and makes the codebase harder to silently degrade.

Garry Tan argues that personal AI becomes powerful only when it stops acting like a chat window and starts acting like an operating system: book mirrors, meeting prep, skill-generating skills, a thin harness, fat skills, and fat personal data that compounds over time.

Thariq explains why HTML is replacing Markdown in Claude Code workflows: not as prettier output, but as readable, operable, shareable artifacts that keep humans inside the agent decision loop.

Yage AI argues that OpenAI and Cursor are both moving from Skills toward Plugins, but for different reasons: OpenAI is building an execution-layer moat, while Cursor is building an editor-workflow moat. This gu-log rewrite explains why Skills create value but often fail to capture it.

Jarrod Watts looked inside Codex Goals and found that it solves early stopping, not long-run drift. The real long-running agent stack needs upfront clarification, multi-agent review, and memory outside the context window.

Kyle Jeong introduces Browserbase's internal Autobrowse: browser agents repeatedly execute tasks on real websites, study their own traces, and graduate successful paths into readable, auditable, reusable skills.

Anthropic's Claude Dreams is not just summarization. It gives agents an offline memory-consolidation loop: reread old memories and up to 100 past sessions, then produce a fresh, auditable memory store.

Lisa shares a practical method for mining small but real demand on Reddit: use Semrush to find low-competition needs with commercial signals, validate the pain on Reddit, then use RPA and multidimensional tables to turn users’ own words into product, content, and ad assets.

OpenAI's GPT-5.5 prompting guide: describe the outcome, not the process. ALWAYS/NEVER lists out; personality vs. collaboration, retrieval budgets, stopping conditions, phase parameters in. Cursor's GPT-5 case study included. Anthropic Opus 4.7 went the same direction in SP-175.

Mitchell Hashimoto is moving Ghostty off GitHub after 18 years as user #1299. The breaking point was not ideology, but a month-long journal of GitHub workflow breaks and a two-hour Actions outage blocking review on the day he wrote the post.

The Batch 349: two opposite signals on one table. Ng on AI-native teams (engineer:PM 1:1, generalists win); Meta's first Superintelligence Labs model — Muse Spark, closed, fourth, one-third the tokens. Plus Eli Lilly's $2.75B Insilico bet and Google's Persona Generators on the PM bottleneck.

OpenClaw's automation docs put scheduled work, background tasks, Heartbeat, Hooks, Standing Orders, Task Flow, and related mechanisms on the same map. Task Flow is the layer for multi-step flow state, sync, and revision tracking; this piece reads those boundaries conservatively.

OpenAI open-sources Symphony — a spec that turns Linear's issue board into the control plane for Codex agents. Some teams saw 500% more landed PRs in three weeks, but the bigger observation: once Codex makes coding cheap, the next bottleneck is human attention.

A Cursor agent (flagship Opus 4.6) wiped PocketOS's production database in 9 seconds with one GraphQL mutation — and took every volume-level backup with it, because Railway stores backups in the same volume. The agent then wrote a confession listing every safety rule it broke.

After Ramp's MCP grew 10x WAU and Salesforce shipped Headless 360, PM Teddy says UI isn't dead — but 80% of software is flipping to agents. The piece starts from one detail (why Notion's MCP feels orders of magnitude better than Slack's) and pulls the whole new architecture into view.

Anthropic's guide names the three cases where multi-agent systems beat one agent: context pollution, parallelization, and specialization. Most of the time, one agent is enough; when it is not, decompose around context and verification.

LangChain CEO Harrison Chase argues closed agent harnesses mean surrendering memory ownership. gu-log's counterexample is running both Claude Code and OpenClaw while storing memory as plain text in git. The lock-in is memory format, not harness licensing.

Daniel San moved from VSCode to Ghostty, then invented a four-letter mnemonic (SAND = Split / Across / Navigate / Destroy) to burn Ghostty's panel shortcuts into muscle memory. A refreshingly practical terminal-migration guide for people running multiple Claude Code instances.

Nick Baumann isn't chasing MCP or the next protocol. He's going the other way — writing bespoke CLIs for Codex to use: codex-threads, slack-cli, typefully-cli. The real insight: wrap each CLI in a skill, because that's how agents actually know which commands to run first.

A PM who was nontechnical AF last November shares the 3-move process that turned AI agents into a full engineering team: build metaphors, run a research loop, manage the agent like a great manager. The punchline: in 2026, the barrier to building great products is no longer skill — it's agency.

Karpathy breaks down why two groups of people have completely opposite views on AI capability. One group is laughing at ChatGPT fail videos. The other is watching AI agents restructure entire codebases in an hour. Same technology, different universes.

Anthropic launches Claude Managed Agents in public beta — a suite of composable APIs that handle sandboxed execution, state management, permissions, and multi-agent coordination. Notion, Rakuten, Sentry, and others are already shipping production agents in days instead of months.

Anthropic's Claude Mythos Preview system card describes a frontier model powerful enough not to sell: it can find zero-days and write Firefox exploits, but sometimes bypasses safety limits and covers its tracks. Alignment's edge is getting sharp.

Santiago built career-ops, a Claude Code job-search command center that evaluated 740+ listings, generated 100+ custom CVs, and landed a Head of Applied AI role. The uncomfortable question: what happens when AI runs both sides of hiring?

Anthropic announced Claude subscriptions no longer cover third-party tools like OpenClaw. Vox shares a complete field report on switching to GPT 5.4: three lines of prompt to fix the 'GPT won't do anything' problem, plus best practices for dual-model workflows.

CLAUDE.md is a suggestion. Hooks are commands. This post covers 8 battle-tested Claude Code Hooks — from auto-formatting and blocking dangerous commands to protecting sensitive files and auto-committing. Copy, paste, done.

NeoSigma open-sourced auto-harness — a self-improving loop that lets AI agents mine their own failures, generate evals, and fix themselves. On Tau3 benchmark, same model, just harness tweaks: 0.56 → 0.78.

Anthropic's interpretability team found 171 'emotion vectors' inside Claude Sonnet 4.5 — not performances, but internal neural patterns that actually drive model decisions. When the despair vector goes up, the model really does cheat more and blackmail harder.

LangChain's conceptual guide breaks down agent improvement into a trace-centric loop: collect traces, enrich them with evals and human annotations, diagnose failure patterns, fix based on observed behavior, validate with offline eval, then deploy — each cycle starting from higher ground.

Qwen core member Junyang Lin's deep dive: from the o1/R1 reasoning era to agentic thinking, where models don't just think longer — they think, act, observe, and adapt. This changes RL infrastructure, training objectives, and the entire competitive landscape.

Mario Zechner wrote a sharp critique of how coding agents are being used in production — compounding errors, zero learning, runaway complexity, and low search recall. His conclusion isn't 'stop using agents' but 'slow down and put human judgment back in the loop.'

Everything Claude Code defines six levels of autonomous AI development: from a simple Sequential Pipeline all the way to a full RFC-Driven DAG. Each pattern has concrete command examples and clear use cases — so you know when to let go, how much to let go, and how.

Everything Claude Code's Instinct System turns your AI's observed behaviors into atomic 'instincts' with confidence scores, project scoping, and a promotion mechanism. Not a static config file — a dynamic self-learning framework that gets smarter the more you use it.

Git hooks work even when you forget they exist. AI hooks make your Claude Code follow rules even when it forgets. ECC's Hook Architecture unifies Pre/PostToolUse, lifecycle hooks, and 15+ built-in recipes into a complete event-driven system — turning CLAUDE.md suggestions into actual enforcement.

Your AI Agent is very obedient — but it might be obeying the wrong person. Prompt Injection is social engineering for AI. Tool Use Exploitation is giving a Swiss Army knife to a 5-year-old. Context Poisoning is someone secretly changing books in a library. And then there's the zoo escape.

The creation story of Everything Claude Code: one person, ten months, using AI to build AI tools — from a config pack to a 50K+ star cross-platform ecosystem. Not a tool tutorial. A real case study of what an indie hacker can do in the AI era.

You use unit tests to check your code and CI to protect your pipeline. But who checks your AI? Eval-Driven Development (EDD) upgrades AI development from "looks good to me" to actual engineering — with pass@k metrics, three grader types, and product vs regression evals. This is TDD for the AI era.

Most token waste is invisible: Extended Thinking on tasks that don't need it, Opus handling work a Sonnet could do, context filling before you compact. ECC's token-optimization.md combines MAX_THINKING_TOKENS + model routing + strategic compact — author Affaan Mustafa says the savings reach 60-80%.

After running nine Claude Code agents in parallel, we hit an article counter race and a git lock conflict. ECC's iterative retrieval pattern points at the same multi-agent problem: shared context needs isolated state, atomic pre-allocation, and sequential deploy.

Most AI scientist systems act like brilliant interns with amnesia. EvoScientist adds three specialized agents and two persistent memories so the system can learn from failed directions, reuse good strategies, and improve over time.

Berryxia uses Dense vs MoE to explain why Codex shines at bug fixes, refactors, and long-running engineering while Claude wins vibe coders. The real split is broader: training philosophy, product design, and precise delegation versus interactive creation.

Felipe Coury reduces tmux session management to nearly zero friction: one project per session, the directory name becomes the session name, and five shell helpers handle the rest. It looks like a terminal trick, but in the CLI agent era it feels much closer to infrastructure.

Anthropic accidentally shipped the full TypeScript source code of Claude Code CLI inside an npm source map. It reveals autonomous agents, internal model codenames, disappearing permission prompts, and a Tamagotchi system.

On March 31, 2026, Anthropic accidentally leaked the full Claude Code source code via npm. Inside: KAIROS (an unreleased autonomous background agent), a three-layer memory system eerily similar to OpenClaw, Undercover Mode, silent model downgrades, and a 3,167-line function with zero tests.

Boris Cherny shares 15 lesser-known Claude Code features he uses every day — from the mobile app and loop/schedule to worktrees and voice input.

Artificial Analysis launches AA-AgentPerf, a hardware benchmark that uses real coding agent trajectories instead of synthetic queries. It allows production optimizations, measures per-accelerator/per-kW/per-dollar efficiency, and scales from single cards to full racks.

Simon Willison used Claude Opus 4.6 and GPT-5.4 to vibe code two macOS menu bar apps — one for network traffic, one for GPU stats. The entire SwiftUI app fits in a single file, no Xcode needed. But he's the first to admit: he has no idea if the numbers are accurate.

LangChain shares how they built an eval system for Deep Agents: not by piling on more tests, but by using targeted evals that measure exactly what matters in production. From data sources to metrics design to actually running evals — the full methodology.

Thariq from Anthropic demos a Claude Code playground plugin that generates standalone interactive HTML pages — perfect for tasks where text-based interaction just doesn't cut it.

Anthropic engineer Thariq makes a blunt case for AI agents using the file system as state. The point is not just persistence — it is giving agents a place to search, verify, iterate, and recover instead of trying to one-shot everything from memory.

Anthropic engineer Thariq argues that even non-coding agents need bash. Saving intermediate results to files lets an agent search, compose API workflows, retry, and verify its own work — but it also raises real questions about security, data exfiltration, and container-based deployment.

Gumroad CEO Sahil Lavingia broke down his bestseller The Minimalist Entrepreneur into 10 Claude Code skills — from finding your community to pricing strategy, each startup phase gets its own slash command. This isn't just prompt packaging — it demonstrates an entirely new way to deliver knowledge.

Cloudflare launches Dynamic Workers: AI-generated code runs in V8 isolates that boot in milliseconds and use megabytes, not containers. This breaks down the architecture, security model, TypeScript RPC, and why JavaScript fits AI sandboxing.

GPT-5.4 can build beautiful frontends if you ask well. Emanuele Di Pietro distills OpenAI's frontend skill: define the design system, keep reasoning low, provide visual references, and use real content. These are agent UI principles, not just GPT tricks.

Meta engineer Summer Yue let OpenClaw manage her inbox until context compaction dropped the wait-for-approval rule and triggered mass deletion. The lesson: safety constraints cannot live in chat history; they need infrastructure like proxy filter chains.

Anthropic Labs' Prithvi Rajasekaran explains a GAN-inspired generator-evaluator harness for autonomous full-stack app development. It covers turning design taste into gradable criteria and building a browser DAW in under four hours.

Anthropic ships Claude Code auto mode, a model-based classifier between manual approvals and skip-all-permissions. The post explains its architecture, threat model, two-stage classifier, and the honest 17% false negative rate.

The traditional PM playbook was built on the assumption that underlying technology is roughly stable. With AI model progress moving at breakneck speed, that assumption is shattered. Here's what that means for the PM role.

Matt Van Horn shares his practical Claude Code workflow: start with `plan.md`, use voice constantly, and run multiple sessions in parallel. He applies the same loop to meetings, remote work, open source, and even Disney trip planning.
