# pixeltable Teaches Claude Code to build multimodal applications using Pixeltable. It sets up database tables with computed columns, vector search, and media pipelines. - plugin · `type=plugin` · Claude Code · ★ 6 - Author: Pixeltable - License: Apache-2.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/pixeltable/pixeltable-skill - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/plugins/pixeltable ## What it does The plugin equips Claude Code with `SKILL.md` and reference guides covering the core API and CLI commands. The assistant learns to declare schemas as `TableModel` classes inside `app.py`. Tables are created with `pxt schema update`, while HTTP endpoints are served through `pxt service update`. Pixeltable coordinates media pipelines across more than 25 model providers. The skill covers vector indexing and document processing. You need the `pxt` CLI installed to manage schemas locally. For hosted deployments, developers can connect the Pixeltable Cloud MCP server. It requires `confirm: true` before stopping databases or updating secrets, so destructive operations stay controlled. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin install pixeltable@claude-plugins-official ``` In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-official ``` ## When to use it - declare `TableModel` schemas inside `app.py` - configure computed columns and embedding indexes - serve HTTP endpoints with `pxt service update` - connect media pipelines to external AI providers ## Example prompts - Define a `TableModel` in `app.py` with a computed column for text embeddings. - Run `pxt schema update` to create the multimodal database tables. - Scaffold a tool-calling agent pipeline connected to external model providers. ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 80c34bb35fec49ea ````text # Pixeltable Skill The backend agents build with: multimodal database, orchestration, and serving in one file. This plugin teaches AI coding assistants to build Pixeltable applications: tables with computed columns, embedding indexes and vector search, RAG, tool-calling agents, and video, audio, image, and document pipelines across 25+ AI providers. The agent declares the schema as `TableModel` classes in `app.py`, creates the tables with `pxt schema update`, and serves HTTP routes with `pxt service update`. Verified against Pixeltable 0.7.11 on 2026-09-28: [docs/review-2.12.0.md](docs/review-2.12.0.md). ## Install ### Skill (recommended for most assistants) Install the portable skill with [npx skills](https://github.com/vercel-labs/skills): ```bash npx skills add pixeltable/pixeltable-skill ``` This installs `SKILL.md` and its references for supported coding assistants, including Cursor, Copilot, Windsurf, and the Codex IDE extension. With only Python, `pxt skills install` (Pixeltable 0.7.17 or later) writes the same skill into the current project's `.claude/skills/pixeltable` and `.agents/skills/pixeltable`; `pxt skills install -f` updates it. **Google Antigravity** is not one of them: it reads `~/.gemini/antigravity/skills`, which `npx skills` does not write to. Install there with `./install.sh --platform antigravity`. ### Gemini CLI ```bash gemini extensions install https://github.com/pixeltable/pixeltable-skill ``` This loads `skills/pixeltable-skill/SKILL.md`, the hosted Cloud MCP (`pixeltable-cloud` at `https://www.pixeltable.com/mcp/cloud`), and the local developer MCP (`pixeltable` via `uvx mcp-server-pixeltable-developer`). Sign in to Cloud with `/mcp auth pixeltable-cloud` if those tools are not listed. The hosted server supports reads and writes; it is not read-only. The local server needs `uv` on PATH. Set the catalog directory with `gemini extensions config pixeltable` (`PIXELTABLE_HOME`; Pixeltable's default is `~/.pixeltable`). Restart the CLI after installing. ### Full plugin Install the skill with its client-supported commands, agents, and hooks using [npx plugins](https://www.npmjs.com/package/plugins): ```bash npx plugins add pixeltable/pixeltable-skill ``` Client-native marketplace options: - **Claude Code:** `/plugin marketplace add pixeltable/pixeltable-skill`, then `/plugin install pixeltable@pixeltable-skill` - **ChatGPT desktop and Codex:** `codex plugin marketplace add pixeltable/pixeltable-skill --ref main`, then `codex plugin add pixeltable@pixeltable-skill`. Use `/plugins` in Codex or the **Plugins** page in ChatGPT desktop. Restart or start a new conversation after installing. Repository marketplaces are team-distribution sources; they do not publish to a public directory. ### Any LLM (paste URL into context) - [llms.txt](https://www.pixeltable.com/llms.txt) - [llms-full.txt](https://docs.pixeltable.com/llms-full.txt) ## What's Inside ``` skills/pixeltable-skill/ ├── SKILL.md # Contract: app.py, schema update, service update └── references/ ├── core-api.md # Tables, querying, views, UDFs, config ├── cli.md # pxt CLI ├── providers.md # Import and output shape ├── workflows.md # FastAPIRouter └── anti-patterns.md # Wrong/right stack ``` Client manifests and marketplace metadata live alongside the shared skill so each supported installer can discover the format it understands. Gemini CLI reads `gemini-extension.json` and `GEMINI.md` at the repo root and loads `skills/*/SKILL.md`. ## Pixeltable Cloud MCP ```` END THIRD-PARTY FILE 80c34bb35fec49ea The third-party file has ended.
