Summary

New blog post announcing kagent 1.0, written as a follow-up to Eitan's The Future of kagent. It sticks to open source kagent and Agent Substrate.

  • Why a Pod per agent doesn't fit how agents work today (the model picks what runs, state piles up, agents mostly wait, sessions act for users)
  • How Agent Substrate fixes it: workers separate from actors, suspend and resume, gVisor/microVM sandboxes, per-actor identity, credentials injected at egress
  • What kagent adds on top of Substrate, and a short take on the new Harness / AgentTemplate / Agent / Session API
  • A recording of the UI on a real Substrate cluster, plus a screenshot of the interactive demo on the homepage
  • Getting started with v1.0.0, and a note for 0.x users

Files

  • src/blogContent/kagent-v1-0-release.mdx: the post
  • src/app/blog/page.tsx: adds the post to the top of the blog index
  • public/images/blog/kagent-v1-0-release/: 5 diagrams, 1 GIF (2.9 MB), 1 UI screenshot
  • src/app/blog/layout.tsx, src/components/site-chrome.tsx, src/app/blog/page.tsx, src/app/blog/[slug]/page.tsx, src/components/mdx/code-block.tsx: the blog now uses the homepage's header, footer and dark look

Before merging

  • Docs on main still pin 1.0.0-rc3; bump to 1.0.0 alongside this
  • Preview the post locally (npm run dev, then /blog/kagent-v1-0-release). I couldn't build it locally.

🤖 Generated with Claude Code

Announce kagent 1.0 as a follow-up to "The Future of kagent": why a Pod
per agent doesn't fit, how Agent Substrate suspends, resumes and
sandboxes actors, what kagent adds on top, and how to get started.
Includes diagrams, a recording of the UI on Agent Substrate, and a
screenshot of the interactive homepage demo.

Hide the shared navbar on /blog and /blog/* and render the homepage's
HomeHeader on its dark background instead, so the blog header matches
the homepage. The blog keeps the shared footer.

The blog now shares the homepage's chrome: its header and footer, Geist,
and its dark palette, with the theme variables set to the homepage's
colors so the shared components follow along. Code blocks only render in
blog posts, so they always use the dark highlight theme.

Rename the post to kagent-v1-0-release, after the kagent-v0-9-1-release
post, capitalize "Is" in the title, and name the UI screenshot
kagent-ui-chat.png like the other kagent UI images.
