Reticle gives coding agents a verdict on the running app

GitHub preview card for the reticlehq/reticle repository, showing its name, a description of runtime perception for AI agents, a black icon, and counts for contributors, users, discussions, stars, and forks.

Reticle helps coding agents check what they actually built rather than stopping at the code change. The repository presents a runtime-perception tool for web and desktop apps; reticle compare drives two builds in a browser and reports differences users can see, network calls, and console errors.

Verification happens from outside the app, with no SDK required. The comparator can pit a main build against a pull request preview and, with --base, classify differences as regressions, missed targets, or changes.

Next.js 16.4: faster navigation without prefetching everything

nextjs.orgPermalink

Next.js visual showing the article title about improving navigation in v0.

To reduce loading skeletons in v0, the team combines Next.js Partial Prefetching with cache rules suited to public and personalized data. Playwright instant() tests check that priority content is ready at click time, and remain in the codebase as CI regression checks.

Prefetching also responds to user intent: in large grids, details load on hover, focus, or touch rather than for every visible card. That adjustment followed a 2.9× increase in prefetch requests. The overall comparison reports lower daily costs, while cautioning that the change cannot be attributed to this refactor alone.
