# nx-run-tasks Tells the agent how to run build, test, lint and serve targets in an Nx workspace. Useful when a monorepo has more projects than you can track. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 3800 installs · ★ 29 - Author: nrwl - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/nrwl/nx-ai-agents-config/tree/HEAD/skills/nx-run-tasks/SKILL.md - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/skills/nx-run-tasks ## What it does The skill covers how tasks work in an Nx workspace. The agent first checks which targets exist, then picks the right command. You can list them with `nx show project --json` — the response has a `targets` section. The skill also suggests reading `package.json` or `project.json`, but warns that this misses tasks inferred by Nx plugins. A single target runs as `nx run :`. Several at once go through `nx run-many -t build test lint typecheck`, with `-p`, `--exclude` and `--parallel` to narrow things down. For large repos and CI there is `nx affected`, which only touches changed projects and their dependents, comparing against the base branch by default. One wrinkle is invocation. If `nx` is not installed globally, the command needs an `npx`, `pnpx` or `yarn` prefix — the skill has the agent figure out the package manager from `package.json` or the lockfile, so a machine without a global Nx will not trip it up. The same flags work across all three modes: `--skipNxCache` to rerun anyway, `--verbose` for stack traces, `--nxBail` to stop at the first failure, `--configuration=` for a specific configuration. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add nrwl/nx-ai-agents-config --skill nx-run-tasks -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/nx-run-tasks/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/nx-run-tasks/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add nrwl/nx-ai-agents-config --skill nx-run-tasks -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/nx-run-tasks/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add nrwl/nx-ai-agents-config --skill nx-run-tasks -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/nx-run-tasks/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install nrwl/nx-ai-agents-config nx-run-tasks ``` 2. **Manually: put the files in place** - File: `.github/skills/nx-run-tasks/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add nrwl/nx-ai-agents-config --skill nx-run-tasks -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/nrwl/nx-ai-agents-config --path skills/nx-run-tasks ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/nx-run-tasks/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add nrwl/nx-ai-agents-config --skill nx-run-tasks -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/nrwl/nx-ai-agents-config/tree/HEAD/skills/nx-run-tasks/SKILL.md ## When to use it - build a single project inside a monorepo - run tests and lint across several packages at once - build only the projects changed in CI - rerun a task while bypassing the Nx cache - stop a run after the first failed task ## Example prompts - build the myapp project - run tests and lint for every project tagged api-* - run an affected build against the main branch ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE fb4c77fa480e2832 ````text --- name: nx-run-tasks description: Helps with running tasks in an Nx workspace. USE WHEN the user wants to execute build, test, lint, serve, or run any other tasks defined in the workspace. --- You can run tasks with Nx in the following way. Keep in mind that you might have to prefix things with npx/pnpx/yarn if the user doesn't have nx installed globally. Look at the package.json or lockfile to determine which package manager is in use. For more details on any command, run it with `--help` (e.g. `nx run-many --help`, `nx affected --help`). ## Understand which tasks can be run You can check those via `nx show project --json`, for example `nx show project myapp --json`. It contains a `targets` section which has information about targets that can be run. You can also just look at the `package.json` scripts or `project.json` targets, but you might miss out on inferred tasks by Nx plugins. ## Run a single task ``` nx run : ``` where `project` is the project name defined in `package.json` or `project.json` (if present). ## Run multiple tasks ``` nx run-many -t build test lint typecheck ``` You can pass a `-p` flag to filter to specific projects, otherwise it runs on all projects. You can also use `--exclude` to exclude projects, and `--parallel` to control the number of parallel processes (default is 3). Examples: - `nx run-many -t test -p proj1 proj2` — test specific projects - `nx run-many -t test --projects=*-app --exclude=excluded-app` — test projects matching a pattern - `nx run-many -t test --projects=tag:api-*` — test projects by tag ## Run tasks for affected projects Use `nx affected` to only run tasks on projects that have been changed and projects that depend on changed projects. This is especially useful in CI and for large workspaces. ``` nx affected -t build test lint ``` By default it compares against the base branch. You can customize this: - `nx affected -t test --base=main --head=HEAD` — compare against a specific base and head - `nx affected -t test --files=libs/mylib/src/index.ts` — specify changed files directly ## Useful flags These flags work with `run`, `run-many`, and `affected`: - `--skipNxCache` — rerun tasks even when results are cached - `--verbose` — print additional information such as stack traces - `--nxBail` — stop execution after the first failed task - `--configuration=` — use a specific configuration (e.g. `production`) ```` END THIRD-PARTY FILE fb4c77fa480e2832 The third-party file has ended.
