AI Coding Tools
AI coding tools range from autocomplete in the editor to agents that take a ticket and come back with a pull request. The market moves weekly: new models, new pricing, new agent modes.
This page tracks that movement across Cursor, GitHub Copilot, OpenCode, Antigravity, Devin and others, with our guides on vibe coding and agentic development.

How to Work With AI Coding Agents: Thorsten Ball's 15 Rules
Thorsten Ball, who works on the Amp coding agent, posted a 15-point list on how he works with agents as of October 2026. It passed 295K views in hours. We unpack each rule, show how to apply it with Claude Code or Codex today, and flag where the advice needs a grain of salt.
Gemini 4 Argon Built a 3D Periodic Table in Antigravity: How to Recreate It
Google DeepMind posted a 1:28 demo of Gemini 4 Argon building a 3D periodic table with orbiting electrons, atomic data and light spectra, synced to a classic song, inside Antigravity. We separate the showcase from the benchmark and show how to try a version yourself.
Shipping AI-Written Code You Do Not Understand: What an Ask HN Thread Gets Right and a Practical Playbook
An Ask HN thread asks how to deal with shipping AI-written code you do not understand, quoting a Meta engineer who says it all feels like a black box. The replies split between trust-the-tests and quality-still-matters. This post turns the debate and the published evidence into a practical playbook.
Multiple $20 AI Accounts or One $200 Plan? Fix Your Context First
Stacking several $20 accounts looks like a cheap way to get more AI coding usage. The math says a $200 plan buys twice as much per dollar at Claude, Cursor and Google, the terms say stacking is risky, and the real leak is almost always stale context. Here are the numbers, a re-read calculator, and a habit list that works on every vendor.
AI-DLC from AWS Labs: Gated Workflows for Claude Code, Codex, Cursor and Kiro
AWS Labs has turned its AI-DLC methodology into an MIT-0 licensed toolkit that wraps seven coding agents in staged workflows with human approval gates. Here is what is in it, how to try it, and where to be careful.
Taste vs Judgment: A Two-Filter Guide to Picking One AI Draft
When a model produces many acceptable options at once, taste alone cannot choose between them. This guide explains the two-filter method from Addy Osmani's framing: taste cuts the pile to a few, judgment, the price of quality, picks the one to ship. Includes prompts, a decision rubric, failure modes and an interactive lab.

Heal Benchmark: AI Code Reviewers Miss 70% of Runtime Bugs, Claimed vs VerifiedHeal, a runtime-testing agent, published a benchmark claiming AI pull-request reviewers miss 70 percent of the user-facing bugs it proves with failing tests. The numbers are interesting and the method has real limits. Here is what is claimed, what the page itself concedes, and how to test it on your own repo.

What Does a Coding-Agent Harness Buy? Mostly Tokens, a New Study FindsA controlled study of 8,032 trials finds that swapping the coding-agent harness (Claude Code, OpenCode, mini-SWE-agent) moves SWE-bench Verified pass rates about as much as rerunning the same setup, while cost per task can triple. Here is what the numbers say and what to change in your own setup.
Oct 23
Cursor Computer Use: Local Agents Can Now Click and Type in Any Desktop AppCursor announced a Computer Use tool on October 23, 2026 that lets its agents click and type across any app on your computer, not just the browser. Here is what Cursor has said, what its docs already confirm about cloud agents, and the security questions to ask before turning it on.

Self-HPO: Microsoft Research's Coding Agent That Rewrites Its Own HarnessSelf-HPO, from Microsoft Research and the University of Virginia, alternates two steps: the model rewrites the harness around it, then reinforcement learning trains the model inside that harness. Starting from Qwen3.5-35B-A3B, it lifts the average resolve rate over three SWE-bench variants from 57.8% to 64.8% with no stronger teacher model.

Steam Next Fest and the "No AI" Filter Request: What Valve Already RequiresAs Steam Next Fest began on October 19, 2026, IGN reported players complaining about AI-generated art and vibe-coded games and asking Valve for a filter. Valve has required AI content disclosure since January 2024, so a filter is technically close, but tags, definitions and enforcement are the real problem. Here is the situation, the options, and what developers and players can do now.

Vortex Code and Architect: Spinoza Labs' "One Prompt, a Software Team" Claim vs What Is VerifiedSpinoza Labs launched Vortex Code, a coding CLI with Agent, Build and Architect modes, and published demo counts such as 173,773 lines and 1,111 commits for one finance terminal. We separate what the company claims from what can be checked, and give you a way to test it.

AI Coding Agents Add 30% More Code, Not More Finished Software: The Harvard Review-Bottleneck StudyA Harvard job-market paper using Jellyfish data from over 700 software firms finds that AI coding agents raise lines of code, commits and pull requests, but the rate of finished Jira issues does not move. Code review absorbs the gain. Here is what the study measured, what it cannot prove, and what to change in your own workflow.

ts-rust: An LLM-Written Rust Port of the TypeScript Compiler, TestedThe pingdotgg team ported the Go-based TypeScript 7 compiler to Rust almost entirely with LLMs. The README claims 181,711 ported tests pass and about half the type-check time of Go. It also says nobody read the code. We read the repo and the Hacker News thread.

Devin Dreaming Memory and the Agent Memory Repo Open Spec, ExplainedCognition gave Devin persistent memory stored as a git repository of markdown files, plus a daily Dreaming pass that merges and prunes it. The format is an open spec that other agents can use too. Here is how it works, how it compares, and where it can go wrong.

Karpathy: Ask for Discardable Software Artifacts Now That Code Is AbundantOn October 2, 2026, Andrej Karpathy argued that as intelligence and code become abundant, you can ask for large, custom, discardable software artifacts, such as web apps and video explainers, that would never have made sense to build before. The shift is economic, not a new model capability.

Programming Languages in the AI Era: What to Expose to AgentsJosé Valim's September 24, 2026 essay asks what programming languages should optimize for once coding agents are users. The practical answer is three surfaces: explicit types, a queryable program database, and runtime state an agent can inspect.

What a Prince of Persia Fan Port Shows About Coding AgentsPriyan R spent months handing Prince of Persia to frontier coding agents and only playing the result. Opus 5.5 got a level-1 screen from 8,429 differing pixels down to 2. The useful part for anyone grading agents is the oracle and the diff, not a leaderboard of model names.

Google Antigravity /plan: dedicated planning mode before the agent executesOn September 25–26, 2026, Google Antigravity shipped a dedicated planning mode: type /plan and the agent researches, drafts an implementation plan for your review, and waits for approval before editing code. The same flow exists on the Antigravity CLI. You can also ask for a plan in plain English for a lighter variant — explainx.ai maps how /plan fits next to /boost, Teamwork, and harness design patterns builders already use elsewhere.
