# Fullstack Dev > Use when developing the frontend and backend together, making UI changes, or setting up local dev with linked inspect_ai/scout libraries. Triggers on frontend changes, "yarn dev", "vite", "www/", or React component work. - Skill: `tomevault-io/fullstack-dev` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/fullstack-dev` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/fullstack-dev/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/fullstack-dev --- # Frontend application We have a frontend React app in www/. It is pretty lightweight for the moment. It has some views to list eval sets, scans, and samples, from the data warehouse DB. It embeds the inspect_ai and inspect_scout frontend components. If you want to make changes to inspect_ai and inspect_scout, you can link them to this project. Inspect_ai uses yarn and inspect_scout uses pnpm. It's perfectly okay to make changes to inspect_ai and inspect_scout. We can contribute changes upstream. ## Running the backend You should have an env file that corresponds to the environment you're using. E.g. ``` set -a ; source env/dev3; set +a ; uv run fastapi dev hawk/api/server.py --port 8080 ``` ## Running the frontend **Requires Node.js ≥22.12.0** (CI uses 22.21.1). Check with `node --version`. Use `nvm` to install if needed: ```bash nvm install 22 nvm use 22 ``` ``` cd www # optional yarn link "@meridianlabs/log-viewer" yarn dev ``` ## Running dependencies ``` cd ~/dev/inspect_ai/src/inspect_ai/_view/www yarn link -g yarn dev:lib ``` Scout is a little trickier because it uses pnpm not yarn. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/metr) — claim your Tome and manage your conversions.
