Android's command line tool can now drive real devices and guide coding agents
Why it matters Agents writing Android code can now test on real hardware and follow Google's own advice instead of outdated examples.
The Android Developers Blog announced two additions to the Android command line tool. Device Streaming lets you, or your coding agent, control real phones in Google's lab as if they were plugged in. Android skills are official instruction packs that ground agents in current guidance, including a new one for Wear OS with Compose Material 3.
- #2Official
Jetpack Compose 1.13 reaches beta
Why it matters This is the window to test your app on the new version and report regressions before it becomes the default.
Jetpack Compose, Android's UI toolkit, moved to version 1.13 beta this week across UI, runtime, foundation, animation and material, alongside Material 3 version 1.5 beta. Beta means the API surface is frozen, so what you see now is what ships in stable. AndroidX also shipped stable updates to Collection, Paging and Wear Compose in the same release batch.
- #3Official
Google's Agent Development Kit for Kotlin reaches version 1.0
Why it matters Agents inside Android apps are becoming an official pattern, and now there is a first party Kotlin toolkit for building them.
Google released version 1.0 of its Agent Development Kit for Kotlin, with the same features as the Python and Java versions. Kotlin and Android teams can now build agents without switching languages. It arrives alongside Google's new guide to agent workflows inside Android apps and a case study from Instagram's messaging team.
- #4Official
Instagram's messaging team cut AI agent costs by a third with Compose
Why it matters How you structure UI code now affects what AI agents cost to run on it, and this is one of the first numbers from a large production app.
A joint post from Meta and Google explains how the Instagram Direct team, which handles billions of messages, structured its Jetpack Compose interface so that AI agents can work with it more efficiently. The team reports that the token cost of each agent session fell by 33 percent. The post walks through the architecture behind that number.
- #5Official
The Kotlin Multiplatform plugin is dropping Swift editing
Why it matters Teams that edit their iOS Swift code inside Android Studio will need Xcode or another editor for that part.
JetBrains is removing Swift features from its Kotlin Multiplatform plugin, the tool for sharing Kotlin code between Android and iOS. Starting with IntelliJ IDEA 2026.3 and Android Studio Rabbit 2, the plugin will no longer edit, highlight or navigate Swift files, including jumps between Swift and Kotlin. The Kotlin side of shared code is not affected.

AOSP / AndroidX insider
Google is finishing a batch passkey API in Credential Manager, removing old Android XR panel APIs, and making a Compose accessibility behaviour the default.
[Batch Passkey] Rename the batch passkey callbacks and result types
Credential Manager is shaping a batch passkey API (create or use several passkeys in one call); renaming callbacks suggests the surface is settling before a release.
Remove Deprecated Orbiter APIs
Deprecated Orbiter APIs removed from AndroidX XR: the spatial UI surface is being consolidated ahead of a stable release.
Remove AndroidComposeUiFlags.isPropagateHideFromAccessibilityToMergingChildrenEnabled
A Compose UI accessibility feature flag was removed, meaning the merged-semantics 'hide' behaviour is now the default.

Today’s Product & AI picks
- #1Across sources
Microsoft ships a small model just for agent decisions
Why it matters Agents make many small calls per task, so a cheap, consistent judge can matter more than a smarter general model.
Microsoft released Microsoft Decision 1, a fast model that scores decisions inside AI agents and workflows, such as whether to approve, route or rank something. The first version is built on Qwen 3.5 with nine billion parameters, and Microsoft says it will move it onto its own and OpenAI's models. The same idea showed up today on Hacker News, at a Y Combinator startup and on Hugging Face.
- #2Fastest rising
An agent-powered reverse engineering tool gains 25 thousand stars in a day
Why it matters Work that needed rare experts is getting cheap, which matters for security, modding and app protection, though the tool's claims are still unproven.
An open source project called rea promises to reverse engineer anything with AI agents, from how an app behaves down to its native binaries. It gained about 25 thousand GitHub stars in a single day. On the same day, reports described hundreds of old games being decompiled and ported to the browser with help from Claude.
- #3New idea
New Mac tools tell you which coding agent needs you
Why it matters When developers supervise several agents at once, the scarce resource is attention, and that is becoming its own product category.
Several launches today tackle the same new problem: keeping track of many coding agents at once. Farol is a Mac terminal that shows which agent is waiting for you. Littleguys puts Claude Code and Codex agents in the menu bar, and Halo uses the MacBook notch for agent status. None of them write code. They route your attention.
- #4Fastest rising
Google's EmbeddingGemma 2 tops Hugging Face and already runs in the browser
Why it matters Good multimodal search no longer needs a server, which opens up on-device search features for mobile apps.
EmbeddingGemma 2 is Google's new open embedding model. It turns text, images, audio and video into vectors for search and recommendations, under the Apache license. It is the top trending model on Hugging Face, and within days the community had compressed versions and a demo running fully in the browser with WebGPU.

Small decision models
Microsoft launched a fast decision-scoring model for agent workflows, a 'build your own decision model' post sits high on HN, a YC company sells a fraud/risk decision model at a fraction of frontier cost, an 11MB local decision model launched on Product Hunt, and a decision-model leaderboard is trending on Hugging Face.
Why now. Agent pipelines now make dozens of small yes/no and ranking calls per task, so per-decision cost, latency and consistency matter more than raw intelligence.

AI-driven reverse engineering
An agent-powered reverse-engineering repo gained ~25k GitHub stars in a day, a PS5-to-PC porting tool is trending, Techmeme reports hundreds of old games decompiled and ported to browsers with Claude, and HN has several hand-done reverse-engineering and porting stories.
Why now. Coding models can now read disassembly and iterate on decompiled code, collapsing the cost of work that used to need rare experts.

Coding-agent control surfaces
Several launches attack the same new pain: supervising multiple coding agents. A terminal that shows which agent needs you, menu-bar and notch status for Claude Code/Codex agents, an always-on Mac agent, a mod to swap models inside Claude Code, a design-skill pack for agents, and a paper on critics for long-horizon coding agents.
Why now. Running several agents in parallel became normal practice, so the bottleneck moved from writing code to routing human attention.
On-device AI
Google's EmbeddingGemma 2 tops HF and already runs in the browser via WebGPU and as GGUF; Product Hunt has an on-device 'AI computer', offline assistants for phones and local document-to-speech; GitHub has 70B inference on a 4GB GPU; Android devs are fine-tuning small models for on-device agents.
Why now. Small open models (3B-27B) crossed the quality bar for real tasks, and WebGPU, GGUF and phone NPUs make shipping them practical.

Self-improving agents
A YC company sells agents that get cheaper and better with each run, papers on RL-driven self-improvement, reflective rulebooks, self-improving robot code and agent memory compaction trend on HF, a chip startup pitches hardware for recursive self-improvement, and agent infrastructure (persistent per-agent VMs, agent runtime security) is raising money.
Why now. Agents now run the same tasks thousands of times, which makes learning from past runs both possible and economically valuable.

Agent-ready Android
Google shipped Android CLI device streaming and 'Android skills' to ground agents, ADK for Kotlin hit 1.0, the official blog published an in-app agentic workflows guide and a Meta case study on AI-native Compose UI, a Developer Knowledge MCP server went public, and AppFunctions keeps moving through alpha.
Why now. Coding agents are mainstream in Android teams and agents inside apps are becoming a platform feature, so Google is making its docs, devices and Kotlin stack machine-usable.

Product notes
Who each product is for, the problem, why now, its wedge and how it makes money. Today’s picks first.
Microsoft-Decision-1
- What
- A fast model from Microsoft that scores decisions inside agents and workflows, initially trained on Qwen3.5-9B.
- For whom
- Teams building agent pipelines that need cheap, consistent judgments (route, approve, rank) at each step.
- Problem
- Calling a frontier model for every small routing or approval step is slow, expensive and inconsistent.
- Why now
- Agent workflows make many small judgments per task, so per-decision cost dominates; it matches Nadella's call for deterministic systems around powerful models.
- Wedge
- A narrow job done cheaply and fast, from a vendor enterprises already buy from.
- Money
- Likely metered through Azure; Microsoft says it will rebase the model on MAI, OpenAI and other models.
- Like
- Grayson (YC) · ej · LLM-as-judge reward models
LessonWhen a general capability gets used in a narrow, repetitive slot, a specialised small model can win on cost and consistency.
morluto/rea
- What
- An open-source tool that uses AI agents to reverse-engineer software, from observed app behaviour down to native binaries.
- For whom
- Security researchers, modders and engineers who need to understand closed software without source.
- Problem
- Reverse engineering is slow, expert-only work in tools like Ghidra or IDA; most developers cannot do it at all.
- Why now
- Coding models can now read disassembly and iterate; the same wave is decompiling old games at scale (see Techmeme today).
- Wedge
- One open repo with a sweeping promise ('reverse engineer anything'), riding agent interest to viral GitHub growth.
- Money
- None stated; open source. A hosted or enterprise security product is the obvious later path.
- Like
- Ghidra · IDA Pro · Binary Ninja
'Anything' is a very broad claim, and ~25k stars in a day reflects virality more than proven results on real binaries.
LessonAn audacious promise on a hot capability buys distribution; retention depends on whether it survives contact with real targets.
Farol
- What
- A macOS terminal that shows which of your coding agents needs your attention.
- For whom
- Developers running several coding agents in parallel.
- Problem
- With multiple agents running, it is easy to lose track of which one is blocked waiting for input.
- Why now
- Running several agents at once is becoming normal; Littleguys, Halo and Agibot launched around the same idea today.
- Wedge
- Owning the terminal, where coding agents already run, instead of adding a separate dashboard.
- Money
- Not stated; likely a paid Mac app or a pro tier.
- Like
- Littleguys · Warp · iTerm2
LessonWhen users shift from doing to supervising, the valuable UI is attention routing, not more output.
google/embeddinggemma-2
- What
- Google's EmbeddingGemma 2: an Apache-2.0 multimodal embedding model covering text, images, audio and video.
- For whom
- Developers building search, RAG and recommendations, including on-device and in-browser.
- Problem
- Strong multimodal embeddings have mostly been API-only or too large to run locally.
- Why now
- Within days it is quantised (Unsloth GGUF) and running in the browser over WebGPU, showing small open embeddings can be deployed anywhere.
- Wedge
- Open licence plus Google's name, small enough for devices.
- Money
- Free; it strengthens the Gemma ecosystem and Google Cloud.
- Like
- OpenAI text-embedding-3 · Jina Embeddings · Nomic Embed
LessonOpen, small and multimodal is a distribution strategy: the community ships the ports for you.
Maritime: Fully managed cloud for running AI agents at scale
- What
- A managed cloud where every AI agent runs on its own isolated, persistent VM.
- For whom
- Companies running many long-lived agents that need state, tools and isolation.
- Problem
- Serverless functions and shared containers fit badly with agents that run for hours, keep state and execute untrusted code.
- Why now
- Agents moved from chat turns to long-running jobs with real tool access, which needs persistent and safe compute.
- Wedge
- One infrastructure primitive, a VM per agent, promised at 'millions of agents' scale.
- Money
- Usage-based compute pricing, like other cloud platforms.
- Like
- E2B · Modal · Fly Machines
LessonA new workload shape (long-lived, stateful, untrusted) can open space for new infrastructure even in a mature cloud market.
Show HN: BetterWispr – Free, open-source dictation for Mac
- What
- A free, open-source dictation app for Mac.
- For whom
- Mac users who dictate messages, documents and especially prompts to AI tools all day.
- Problem
- The best dictation apps are subscriptions, and built-in dictation is noticeably weaker.
- Why now
- Local speech models now run fast and accurately on Apple silicon, so a free app can match paid quality.
- Wedge
- Free and open source against a paid incumbent the name points at directly.
- Money
- None; open source.
- Like
- Wispr Flow · Superwhisper · macOS Dictation
LessonNaming yourself 'Better X' is cheap, instant positioning when you are the free alternative to a known paid product.
Show HN: WallHop – 12ft.io is gone, so I built a replacement
- What
- A free web tool that shows a readable article without the paywall pop-up, ads or clutter; no signup and no extension.
- For whom
- Readers hitting soft paywalls, especially on phones (it ships an iOS Shortcut).
- Problem
- 12ft.io, the usual tool, was taken down in July 2025 after pressure from the News Media Alliance.
- Why now
- The incumbent's removal left a gap; it chains several bypass methods and falls back to archive.is so one blocked trick doesn't break it.
- Wedge
- A URL-prefix trick plus a share-sheet shortcut: zero install, works from a phone.
- Money
- None stated; free. Legal pressure, the thing that killed 12ft.io, is the main business risk.
- Like
- 12ft.io · archive.today · everywall/ladder
LessonA takedown leaves ready-made demand behind, but whatever removed the incumbent will come for the replacement too; plan for it from day one.
Ghost Core
- What
- A 'personal AI computer' that runs entirely on-device.
- For whom
- Privacy-minded users who want an assistant without sending data to the cloud.
- Problem
- Cloud assistants see all your data, and do-it-yourself local setups are fiddly.
- Why now
- Small open models (Qwen3.8, LiquidAI d1, Gemma) are now good enough to run useful assistants locally.
- Wedge
- Privacy as the headline: nothing leaves the device.
- Money
- Unclear from the listing; 'computer' may mean a hardware sale.
- Like
- KernelAI · Ollama · Rabbit R1
'Personal AI computer' is vague; the listing doesn't say whether it is hardware or software or what jobs it does well.
LessonOn-device wins when paired with a concrete job; privacy on its own rarely sells a product.
Grep AI: Self-improving agents that get smarter and cheaper at the same task
- What
- A platform to build an agent in minutes that gets smarter and cheaper every time it runs the same task.
- For whom
- Teams automating repeated, high-volume workflows.
- Problem
- Agents cost as much on the thousandth run as on the first, and do not learn from what worked.
- Why now
- Self-improvement research (MiMo-V2.6, Memento 3) and cheap distillation make 'learn the task, then hand it to a smaller model' practical.
- Wedge
- Cost that falls with usage, a pitch finance teams understand immediately.
- Money
- Likely usage-based pricing that captures part of the savings.
- Like
- OpenPipe · Predibase · DSPy
LessonA unit cost that improves with volume is a strong story in any market where spend scales with usage.
cathrynlavery/diagram-design
- What
- A skill pack that makes coding agents (Claude Code, Codex, Copilot, Cursor, Factory Droid, Pi) produce editorial-quality diagrams as self-contained HTML/SVG, with 44 diagram types.
- For whom
- Developers and technical writers who want good-looking diagrams straight from their agent.
- Problem
- Agent-generated diagrams, often Mermaid, look generic.
- Why now
- Agents now load portable 'skills', so design taste can ship as a file that works in many tools.
- Wedge
- A strong, opinionated style ('no shadows, no Mermaid slop') that works across six agent tools.
- Money
- None; open source. It builds the author's reputation.
- Like
- Mermaid · Excalidraw · D2
LessonIn the agent era, taste can be packaged and distributed like a library.
bilawalsidhu/gods-eye-view
- What
- A 'spy satellite simulator' in the browser on a photorealistic 3D globe, using real open data.
- For whom
- OSINT enthusiasts, educators and curious people.
- Problem
- Spatial-intelligence tools are expensive, closed and built for analysts, not the public.
- Why now
- Photorealistic 3D tiles and open live data feeds make this buildable as a single web app.
- Wedge
- A cinematic, shareable framing: a spy satellite, except the data is real.
- Money
- None; open source.
- Like
- Google Earth · CesiumJS · Flightradar24
LessonA vivid metaphor that names a fantasy turns a data viewer into something people share.
Edgee Mod for Claude Code
- What
- A mod that lets you use any model inside Claude Code while keeping your Claude plan.
- For whom
- Claude Code users who want other models for some tasks.
- Problem
- Developers like Claude Code's harness but want model choice, or cheaper models for routine work.
- Why now
- The agent harness has become the part people value; the model underneath is increasingly swappable.
- Wedge
- Plugging into a tool developers already use daily rather than asking them to switch.
- Money
- Likely gateway usage fees from Edgee, which runs an AI gateway.
- Like
- OpenRouter · LiteLLM · claude-code-router
LessonA mod for a tool people love is a fast route to distribution, but you live at the host's mercy.
Invofox – Turn any document into structured, validated JSON
- What
- A document-processing API: send any PDF or image, get accurate, validated structured JSON back.
- For whom
- Software teams that process invoices, forms and other documents.
- Problem
- Extraction is error-prone, and raw model output needs validation before it can go into a database.
- Why now
- Vision models made extraction cheap; the remaining value is accuracy and guarantees.
- Wedge
- Developer-first API with validation built in.
- Money
- Per-document API pricing.
- Like
- Reducto · AWS Textract · Unstructured
LessonWhen a capability becomes a commodity, sell the guarantee (validated output), not the capability.
Device Streaming and Android skills - available in Android CLI
- What
- Android CLI adds Device Streaming (drive remote physical devices) and 'Android skills' that ground coding agents in official guidance.
- For whom
- Android developers working with AI agents and command-line workflows.
- Problem
- Agents generate outdated Android code and cannot test on real hardware.
- Why now
- Coding agents are mainstream in Android teams; Google is making its docs and device fleet agent-accessible.
- Wedge
- Official, CLI-first tools any agent can call, not tied to one IDE.
- Money
- Free; it keeps developers on Google tooling and its device-testing infrastructure.
- Like

Announcing ADK for Kotlin 1.0: Building Production-Ready AI Agents in Kotlin, Android, and Beyond
- What
- Version 1.0 of Google's Agent Development Kit for Kotlin, at feature parity with the Python and Java ADKs.
- For whom
- Kotlin and Android developers building agents on servers or inside apps.
- Problem
- Agent frameworks were Python-first, pushing Kotlin teams to switch languages or hand-roll HTTP calls.
- Why now
- In-app agentic workflows became an official Android pattern this week (Google's 'Build intelligent Android apps' series).
- Wedge
- Parity with Python, so Kotlin teams give up nothing by staying in their language.
- Money
- Free; it pulls agent workloads toward Gemini and Google Cloud.

LessonReaching parity in a team's own language removes the main excuse not to adopt.
Haze 2.0
- What
- Haze 2.0 by Chris Banes: a Glass effect, a new effects API, performance work and experimental native Android backdrop support for Compose Multiplatform.
- For whom
- Compose and Compose Multiplatform developers building blurred or glass-style UI.
- Problem
- Background blur is hard to do well and fast across platforms in Compose.
- Why now
- Glass-style UI is in fashion and Android now offers a native backdrop API Haze can sit on.
- Wedge
- One API across Android, iOS and desktop.
- Money
- Open source; reputation and community.

LessonLibrary authors stay relevant by adopting new platform APIs underneath while keeping their own API stable; his companion post on progressive blur shows how to explain that.
