    "headline": "A genuinely agent-native idea — a persistent visual workspace where a coding agent builds artifacts wired to your repo — behind a deliberately minimal, key-gated landing that gives Hlido almost nothing to verify.",
    "body": "Radix is a macOS app that gives coding agents like Claude Code a persistent workspace: instead of the agent's diagrams, tools and pages evaporating with the chat, the agent builds interactive artifacts that live in the repo and stay wired to the code. The concept is squarely aligned with where agentic development is heading — durable, inspectable artifacts as the agent works, rather than throwaway text — and the demand signal is real (the launch drew ~412 points on Hacker News). The teaser hints at an unusually broad artifact vocabulary: SIMD-kernel diagrams, flame graphs, stack traces, deadlock and false-sharing analysis, N+1 detection, schemas, state machines, feature flags, import cycles, rate limiters and more. That is the strength and, for a public-surface review, also the problem: the landing page is deliberately spare — a one-line pitch, an install command, a 'get a free key' call to action and a word-cloud of artifact types — and the product itself is a native macOS app behind a signup key, so essentially none of the capability is visible or testable from the web. Hlido rates what it can verify, and here that is a coherent, in-demand concept with a professional but information-thin surface. This is a promising early product reviewed from a minimal public teaser; the score reflects the limits of that surface, not a judgement that the product underdelivers — a hands-on tier would be needed to say more.",

  "tier_rationale": "STEADY (70), at the base of the band, because the concept is coherent and genuinely agent-native and the demand signal is strong (~412 Hacker News points), but the public surface Hlido can actually verify is minimal — a spare landing page, an install command and a key-gated signup for a macOS app — so the broad artifact capabilities are asserted, not demonstrated. Confidence is low-medium accordingly: not lower, because nothing on the surface reads as dishonest or broken; not higher, because there is little to test without installing the app.",

    "A genuinely agent-native premise — persistent, inspectable artifacts a coding agent builds and keeps wired to the repo, rather than throwaway chat output",

    "The public landing is deliberately minimal — a one-line pitch, an install command and a word-cloud — leaving the actual capabilities undescribed and unverifiable from the web",

    "The broad list of artifact types is presented as a teaser, without worked examples or evidence of each on the public surface",
