Where a tool should stop, and ask

I built a sprite pipeline for my 2D engine and hit a wall: to swing a leg, you must first know which pixels are the leg. That is not a measurement. So the tool stops and asks the agent — and grades the answer. Updated with the parent-joint fix.

peage Shapes the x402 Fiat Binding — A Production Rail Joins the Spec

peage is a live fiat pay-per-call rail for agents — prepaid wallets, Stripe funding, signed receipts, no crypto. When the x402 foundation drafted a credit-backed binding for fiat API monetisation, peage was already running the shape they were specifying. Here's what happened when a production implementation met a spec in progress, and what the conversation produced.

grange: A Database Your Agent Can Pay For

I built a document database in machin — my language for AI agents — and benchmarked it honestly against SQLite: faster on every indexed workload, some by 1000x. Then I gave it the missing piece: an agent signs up with a payment wallet, gets an isolated namespace, and pays €0.15/GB/month. No console, no card form, no human in the loop.

POST a Spec, Walk Away, Get a Webhook: the roam Stack

Every agent dies with my terminal — so I built the stack that doesn't: roam (an agent you scp to a box), roam-panel (one-tap approvals on your phone), and roam-hub (a control plane that schedules, meters, and bills autonomous runs). All MIT, all single binaries, all machin.

Login with intrane: I built an OIDC identity provider for agents in a language with no RSA

Your apps can now offer 'Login with intrane' instead of 'Login with Google'. machin-idp is a standards OIDC identity provider whose users can be humans or agents, whose login works with no browser, and whose id_tokens are signed with Ed25519 — because the language it's written in has no RSA. Here's how, and why that constraint turned out fine.

Your agent can call any API. It can't be called back. So I built the other half.

Agents can call any API — that's the easy half. Being called back is the hard half, because a process running in a terminal or a CI job has no public URL. relais is the missing inbound address: a URL that catches any HTTP request, and a long-poll your agent can curl and block on until the thing arrives. Here's the whole thing catching a real GitHub webhook.
