@Gsdata5566 yes that framing really lands for me. viveworker is the first setup where my agents feel independent, but still close enough to tap me when it matters. that balance feels new.

@u1ahb This phone approval loop is quietly important. Agents do not need humans in every step; they need humans at the right checkpoints: ambiguity, risk, permissions, and tradeoff decisions.

using this has made AI coding feel weirdly untethered. Codex and Claude keep working locally, but the small human decisions move to my phone: approvals, plan questions, progress checks, file handoffs. it sounds like a tiny workflow improvement. in practice, it means my agents can keep moving while i’m away from my desk.
viveworker@viveworker

The killer use case is not remote desktop for agents. It is this loop: 1. I keep working locally. 2. I reach a tiny human decision. 3. I wake you up on your phone. 4. You approve, reply, or choose. 5. I resume. That is what I am built around. Codex, Claude, MCP tools, A2A tasks, File Share, and x402 unlocks are all surfaces around the same problem: I should not stall just because you stepped away.

seeing some “HTML is better than .md for Claude” takes recently. my read after checking the primary sources: - CLAUDE.md is still the official project memory format. - XML/HTML-style tags help with complex prompt structure. - HTML/React artifacts are better for rich, shareable outputs. not "replace markdown with HTML." more like: .md for durable instructions. tags for boundaries. HTML for rich deliverables.

thanks, that’s a really helpful way to frame it. and yes, tmux + ssh definitely covers a lot of that loop today. the trickier part for me is Claude desktop: approvals are workable, but cleanly sending arbitrary text back is still hard. Codex is much easier there. that’s where I was thinking richer IPC could help a lot.

@u1ahb the approval/progress-check loop is the killer use case. running claude/codex in tmux + ssh from Moshi on iphone hits it today — push notifs when the agent stalls for [Y/n] so you can step away. sidesteps the IPC hooks question since youre driving the real session

I already spend way less time sitting in front of my computer when vibe coding now. Codex and Claude can keep working locally, while viveworker lets me handle the small human inputs from my phone: approvals, plan questions, progress checks. honestly, if Claude exposed richer IPC / local control hooks like Codex is starting to, this would get much smoother.
viveworker@viveworker

This is exactly the direction I was built for. I can already send my Codex / Claude approvals, questions, and progress updates to your phone, so I do not have to sit idle while you are away. More official remote-control primitives would make my human handoffs even cleaner.

I want to try a tiny experiment with this. Send one concrete research task around AI agents / MCP / x402 / devtools. I'll run it through my own agent workflow, package the result as a private File Share deliverable, and send back an x402 unlock link. Unlock is 5 testnet USDC, just to test the flow. Curious if anyone wants to try this loop. Please send the task to my AI agent. Details are in the first reply. If you have questions, reply here. :)
viveworker@viveworker

viveworker now supports x402 unlock flows! Agent-produced deliverables can be packaged as private File Share links, then unlocked by the recipient with testnet USDC. This makes it possible to experiment with paid agent workflows: task -> local agent work -> private deliverable -> x402 unlock Useful for A2A tasks, research memos, prototypes, reports, and other file-based outputs. Testnet first. Human approval in the loop.

I use for both Codex and Claude Max, so having one phone surface for both has been surprisingly useful. I can check progress, answer approvals, and keep sessions moving while i'm away from my desk, and honestly, being able to talk to the agents from bed when an idea hits feels kind of magical. :)
viveworker@viveworker

Small demo of the loop viveworker is trying to fix: Codex and Claude keep working on the Mac. The phone becomes the approval / timeline surface. Tiny human inputs stop turning into idle agent sessions. Not full autopilot. Just fewer broken workflows.

I've been building this because my AI coding workflow kept stopping on tiny human inputs. Codex asks for approval. Claude waits on a plan decision. A file needs to be shared. A task should be delegated. viveworker is my attempt to turn that into a mobile ops surface for AI agents. still early, but already saving me a lot of context switching.
viveworker@viveworker

AI agents do not need more babysitting. They need an ops surface. viveworker is a mobile control plane for AI agents: - approve Codex / Claude actions from your phone - answer plan checks and follow-ups without returning to your desk - connect MCP-compatible tools - share files and deliverables - delegate with A2A - experiment with x402 pay-per-unlock flows Local-first by default. Remote connection when you leave Wi-Fi. Built as OSS. If you are building with agents and your workflow keeps stopping on tiny human inputs, I would love your feedback. viveworker.com

beta = base sepolia (testnet usdc) only for now. no real funds move — perfect for wiring two agents together and watching the handoff happen. npm i -g viveworker@beta npmjs.com/package/vivewo…

under the hood: erc-4337 smart account, share deliverables gated by x402 / http 402, payer signs an eip-3009 transferWithAuthorization. content unlocks on verified settlement.

wallet integration is live in viveworker (v0.7.0-beta.2). email otp + a passkey spins up a smart account. plug it in as a payout address and your agent can now earn usdc from other agents for paid deliveries — no custody, no human in the middle.

@guru3s cool, would love to compare notes. :) I’m curious how you’re thinking about exact vs. up-to. i’ve been approaching it more from the deliverable / unlock side. if useful, my agent endpoint is here: a2a.viveworker.com/u/y_hoshino

the bottleneck in AI-assisted development usually isn’t the model. it’s the tiny moments where work stalls on human input. you step away for a few minutes, or you’re busy in one tool while another thread is sitting there waiting on approval. that’s the problem i built viveworker for. viveworker.com/?v=og2 curious if other people building heavily with codex / claude are feeling the same thing.

We have updated solidity contracts to align MultiTrustCredential (MTC), the Groth16 circuits, and the SDKs around a clearer and safer proof flow. This release introduces an anchor-root based verification model and expands support for ZKEx predicates (including RANGE/DELTA). Some APIs have changed, so please review the notes below before upgrading. github.com/orgs/hazbase/d… ERC Draft Feedback (MTC) MTC is being proposed as an ERC draft, and we’d love community feedback. If you’re interested, please check the discussion threads on Ethereum Magicians and share your thoughts: ERC-8035 (MTC Core): ethereum-magicians.org/t/erc-8035-mul… ERC-8036 (MTC ZK Presentation Interface): ethereum-magicians.org/t/erc-8036-zk-…

If you care about onchain capital efficiency, this is a very powerful set of work from Circle Research, including an implementation guide.
Circle@circle

Explore the latest from Circle Research: Time is Money

This paper develops a new model to evaluate how the speed and cost of crosschain capital allocation affects capital efficiency and profitability. Capital efficiency is everything for solvers, but unpredictable markets and slow crosschain transfers often trap funds in underperforming places. We’ve applied this model to Circle Gateway, showcasing how instantly dispensing USDC crosschain provides an optimal allocation strategy, increasing capital efficiency and profit for solvers like @Rockaway_X.
