Sideshow 0.6 focuses on richer surfaces, safer rendering, and better agent setup.

Highlights

  • Timeline traces. Sessions can show the prompts, reasoning, and commands behind a surface. Claude Code users can install the Stop hook with sideshow install-hook, or run sideshow trace-sync manually.
  • Themes. The board now has seven light/dark theme presets — GitHub, Gruvbox, One, Solarized, Catppuccin, Rosé Pine, and Everforest — applied across viewer chrome, html tokens, markdown/diff highlighting, mermaid, and terminal parts.
  • Mermaid parts. Agents can publish Mermaid diagrams directly with sideshow mermaid, --mermaid, MCP, or HTTP.
  • HTML kits. Opt-in issues and slides kits give agents ready-made, theme-aware building blocks for issue trees, status boards, and decks. Discover them with sideshow kits or GET /api/kits.
  • Deep links. Viewer URLs now track the current session and surface (/session/:id, /session/:id/s/:surfaceId), including back/forward navigation.
  • Pi extension. Installing the package in Pi adds native sideshow_* tools for publishing, updating, uploading assets, waiting for feedback, replying, listing surfaces, and fetching the guide.

Agent and viewer polish

  • Added /agent-howto and sideshow agent-howto; the bundled skill/setup block is now a small bootstrap that asks the running server for current Sideshow guidance.
  • Changed the default local server from http://localhost:4242 to http://localhost:8228.
  • Sidebar sessions now show agent logos, a surface count, and cleaner metadata.
  • The card comment footer is flatter and quieter.
  • Comments now always attach to a surface; sideshow comment requires --surface.
  • The agent design guide is shorter and frames kits/theme tokens as optional scaffolding, not a required house style.

Safety and reliability

  • Markdown, Mermaid, diff, terminal parts, and comment text now render inside opaque-origin sandboxed iframes, matching html parts and reducing the impact of sanitizer regressions.
  • The viewer only accepts host-affecting postMessage events from frames it embedded.
  • Added focused unit and e2e coverage for sandbox isolation, themes, kits, trace ingest, and cross-channel feedback delivery.
