The HTML file remains on the developer's workstation while feedback arrives with exact CSS selectors, selected-text range anchors, and visible row and column names for table clicks. Neither cloud hosting nor remote review servers are required. ## Key facts * On 2026-10-04, `lavish-axi` version 0.1.82 was published to the npm registry. * From 2026-09-05 through 2026-10-04, the `lavish-axi` npm package recorded 58,489 downloads. * As of 2026-10-06, the `kunchenguid/lavish-axi` GitHub repository had 3,983 stars and 361 forks. * The local loop uses `lavish-axi ` to launch the browser UI and `lavish-axi poll ` to wait for queued human feedback. * When Tailscale is active, Lavish automatically binds to loopback (`127.0.0.1`) and the host's Tailscale IPv4 address using MagicDNS, enabling tailnet-only mobile review without cloud relays. * The `lavish-axi share` command publishes a standalone inlined HTML copy to third-party host `ht-ml.app`, returning a public URL and an `update_key` rather than an interactive review session. ## How Lavish Editor's local review loop works The review loop connects the agent, Lavish's local server on its default port 4387, and the browser: 1. **Artifact creation**: The agent writes an HTML file into the workspace (for example, `.lavish/plan.html`). 2. **Review session**: The agent runs `lavish-axi `. The CLI starts its background server on port 4387 by default and opens the file in the browser. Sessions are keyed by the file's canonical path. 3. **Reviewer annotation**: Cmd+I or Ctrl+I toggles annotation mode. Clicking an element, selecting text, or choosing a table cell opens an annotation card. The reviewer queues notes in the Conversation panel, edits Mermaid diagrams as Excalidraw whiteboards, or queues layout warnings. 4. **Agent long-polling**: The agent runs `lavish-axi poll `, which long-polls the local server until the user submits feedback or ends the session. 5. **Feedback dispatch**: The reviewer clicks **Send to Agent**. The browser sends queued notes to the server. 6. **Structured return**: `lavish-axi poll` exits, returning queued notes with target tag names, CSS selectors, selected-text ranges, visible table row and column names, and local file paths for attached images. 7. **Updates and live reload**: The agent updates the HTML file. Lavish's file watcher reloads the browser automatically, preserving scroll position and unsent drafts. The agent posts updates using `lavish-axi reply --agent-reply ""` before polling again. ```bash # Agent opens the local artifact lavish-axi .lavish/plan.html # Agent waits for reviewer feedback lavish-axi poll .lavish/plan.html # Agent reports an update back to the review UI lavish-axi reply .lavish/plan.html --agent-reply "Updated the database migration table." ``` ## When an HTML artifact should stay a paragraph An interactive HTML artifact introduces operational overhead: the agent must author complete HTML documents, launch a local web server, spawn a browser tab, and block on a long-polling CLI process. When an answer is a direct technical explanation, an architectural verdict, or a short comparison of two library versions, generating an HTML artifact is unnecessary. Forcing a developer to switch windows and click review bubbles for information that belongs in terminal text creates friction. An HTML artifact is justified when spatial layout and visual precision prevent misunderstanding: * **Decision matrices**: Tables where multiple technical trade-offs require side-by-side scanning across columns and rows. * **System diagrams**: Mermaid whiteboard diagrams where sequence lifelines or entity relationships cannot be conveyed clearly in sequential text. * **Interactive selection forms**: Technical roadmaps where the user toggles scope or selects options before the agent writes code. * **UI mockups**: Layout proposals where pointing directly at a button or container removes ambiguity about what to modify. If a response does not require spatial pointing or interactive user input, it should stay a paragraph in terminal chat. ## Tailscale local networking versus public ht-ml.app hosting Lavish provides two distinct ways to access HTML artifacts outside the local desktop: Tailscale network binding and ht-ml.app publishing. ### Tailscale network binding When Tailscale is active, Lavish binds its HTTP server to loopback (`127.0.0.1`) and the host's Tailscale IPv4 address instead of `0.0.0.0`. The CLI generates a session URL using the machine's MagicDNS domain (for example, >). Developers can open the review on a phone or laptop on the same tailnet. Because the device connects directly to the local server, the review loop remains local: mobile annotations reach the agent through `lavish-axi poll` without a cloud relay. The server is unauthenticated, so the tailnet is the trust boundary. ### Public hosting on ht-ml.app The `lavish-axi share ` command publishes an artifact to `ht-ml.app`, an independent third-party hosting service. Lavish packages the artifact by inlining local assets into a single document, then POSTs it to . The service returns a public URL () and an `update_key`. Hosting on `ht-ml.app` differs from the local review loop: * **Hosted copy, not a review loop**: `lavish-axi poll` talks to the local review server; it cannot receive feedback from `ht-ml.app`. * **Public by default**: Pages are accessible to anyone with the link unless protected with `--private` or `--password `. * **In-place updates**: Agents can overwrite the page in place with `lavish-axi share --site --update-key `, issuing an HTTP PUT request. * **No deletion endpoint**: The `ht-ml.app` API lacks a delete endpoint. Running `lavish-axi share --unpublish --site --update-key ` replaces content with a minimal placeholder locked behind a discarded password. ## Adoption metrics and creator claims As of 2026-10-06, the `kunchenguid/lavish-axi` repository recorded 3,983 stars and 361 forks on GitHub. On npm, `lavish-axi` recorded 58,489 downloads between 2026-09-05 and 2026-10-04\. Package version 0.1.82 was published on 2026-10-04. The project's design philosophy reflects public claims made by creator Kun Chen (@kunchenguid) and interviewers on X: * On 2026-05-12, Kun Chen claimed on X that "HTML is the new markdown" and positioned Lavish as the dedicated editor for agent HTML artifacts, telling developers to instruct agents to "discuss the technical plan with me using `npx lavish-axi`". * On 2026-06-11, Kun Chen claimed on X that `lavish-axi` v0.1.27 is "the quickest way to upgrade your workflow from reading long wall of text and markdown to interactive html artifacts" and asserted that Agent eXperience Interfaces (AXIs) maximize agent token efficiency and task completion rates. * On 2026-06-07, Peter Yang (@petergyang) claimed on X that Kun Chen is an ex-Meta L8 engineer who ships up to 40 pull requests a day using AI agents. While these claims advocate replacing markdown outputs with interactive HTML artifacts, developers must weigh the benefits of visual review against the overhead of running browser servers for simple responses. ## Sources * Lavish Editor repository specification: (read 2026-10-06) * ht-ml.app API documentation: (read 2026-10-06) * npm registry entry for lavish-axi 0.1.82: (read 2026-10-06) * npm download statistics for lavish-axi: (read 2026-10-06) * Kun Chen announcement post on X (2026-05-12): (read 2026-10-06) * Kun Chen skill release post on X (2026-06-11): (read 2026-10-06) * Kun Chen AXI ergonomics post on X (2026-06-11): (read 2026-10-06) * Peter Yang engineering interview post on X (2026-06-07): (read 2026-10-06) _Last verified: 2026-10-06._ Spotted an outdated or wrong claim?
