# Power BI Custom Visuals Skill Build new Power BI custom visuals from natural language using the `powerbi-visuals-tools` SDK. Iteration is agent-driven on TypeScript compile errors; visual correctness is checked once at the end with the user. This skill produces a `.pbiviz` package and embeds it into a PBIR report via `pbi visual import-custom`. The TypeScript project lives **next to** the `.pbip` folder, never inside it. ## Prerequisites The skill needs **Node.js** on PATH and the `powerbi-visuals-tools` npm package. Both are installed on first run with the user's consent; never silently. Pinned versions (override via env vars if needed): - `powerbi-visuals-tools@^5.6.0` (env: `PBIVIZ_VERSION`) - `powerbi-visuals-api@^5.11.0` (pinned in scaffolded `package.json`) The skill's edit patterns and AGENTS.md crib were written against these versions. Bump deliberately. ### First-run prerequisite check ```bash # 1. Probe Node node --version || true ``` If `node` is missing, **ask the user**: > Node.js isn't installed. Custom visual development needs it. Install > now? (yes/no) > > - Windows: `winget install OpenJS.NodeJS.LTS` > - macOS: `brew install node` > - Linux: use your package manager or nvm If user says yes, run the install command appropriate for their OS and re-probe. If user says no, stop the skill with a clear message. `pbiviz` itself runs through `npx --yes powerbi-visuals-tools@^5.6.0`, so there's no global install of the CLI itself. The first `npx` invoc...
