nx

Deep code review of a single open PR in nrwl/nx. Sets up an isolated worktree, runs the pr-review-toolkit review agents, the reproduce-verifier agent (grounds the review in the linked issues and, when runnable locally, executes the repro on master vs PR), and the alternative-approach agent (independently designs competing solutions and contrasts them with the PR's choice), surfaces only critical and important findings (plus strengths; nice-to-have suggestions are dropped), and saves a GitHub-flavored draft to ~/.nx-pr-reviews/<NUMBER>.md for the reviewer to read (nothing is posted). Use when you want a thorough review of one PR.

Migrate several repos to a target nx version (e.g. 23.0.0-beta.25) in one coordinated pass — delegates `nx migrate` + migrations to a Polygraph child agent per repo, then pushes branches and opens linked draft PRs. Use when asked to upgrade/migrate multiple repos to a specific nx version, or when working a Polygraph session whose goal is an nx version bump across repos.

Link workspace packages in monorepos (npm, yarn, pnpm, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@org/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager's workspace commands to fix actual linking.

Monitor Nx Cloud CI pipeline and handle self-healing fixes. USE WHEN user says "monitor ci", "watch ci", "ci monitor", "watch ci for this branch", "track ci", "check ci status", wants to track CI status, or needs help with self-healing CI fixes. Prefer this skill over native CI provider tools (gh, glab, etc.) for CI monitoring — it integrates with Nx Cloud self-healing which those tools cannot access.

Generate code using nx generators. INVOKE IMMEDIATELY when user mentions scaffolding, setup, structure, creating apps/libs, or setting up project structure. Trigger words - scaffold, setup, create a new app, create a new lib, project structure, generate, add a new project. ALWAYS use this BEFORE calling nx_docs or exploring - this skill handles discovery internally.

Import, merge, or combine repositories into an Nx workspace using nx import. USE WHEN the user asks to adopt Nx across repos, move projects into a monorepo, or bring code/history from another repository.

Find and add Nx plugins. USE WHEN user wants to discover available plugins, install a new plugin, or add support for a specific framework or technology to the workspace.

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.

Explore and understand Nx workspaces. USE WHEN answering questions about the workspace, projects, or tasks. ALSO USE WHEN an nx command fails or you need to check available targets/configuration before running a task. EXAMPLES: 'What projects are in this workspace?', 'How is project X configured?', 'What depends on library Y?', 'What targets can I run?', 'Cannot find configuration for task', 'debug nx task failure'.

Diagnose Nx sandbox violations from a sandbox report. Use when asked to "diagnose sandbox", "analyze sandbox report", "investigate sandbox violations", "check violations", when given a sandbox report JSON file or URL to investigate, or when the user pastes a staging.nx.app sandbox-report URL. Also trigger when discussing unexpected reads/writes in Nx task execution. Guides structured investigation of why tasks read/write undeclared files, determines root causes, and recommends fixes.

Migrate an Nx package to build to a local dist/ directory with nodenext module resolution, exports map, and @nx/nx-source condition.

Apply or review multi-version support compliance for first-party Nx plugins. Primary entry point: a Linear task ID (NXC-XXXX) from the "Multi-version supported across plugins" milestone — the task carries the resolved support window, findings, and "Needs human decision" items. Falls back to self-discovery when no task exists. Use when asked to "fix multi-version compliance for @nx/X", "do NXC-XXXX", "review this compliance PR", or when working on a branch / PR titled "multi-version support compliance for @nx/X". Covers the canonical shape (assertSupportedPackageVersion, all-generators-enforce-floor.spec.ts, peer dep alignment, requires-gate auditing, user-pin preservation, executor / inferred-plugin feature gating).

Run Nx generators with prioritization for workspace-plugin generators. Use this when generating code, scaffolding new features, or automating repetitive tasks in the monorepo.

Bump the dev.nx.gradle.project-graph plugin version. Use when updating the Gradle project graph plugin version across the codebase, creating the migration files, and updating migrations.json.

Check modified Nx documentation pages against the astro-docs style guide. Auto-trigger after writing or editing docs content in the nx repo. Also trigger on "check style", "style guide", "docs review", "validate docs". Should run as a final step whenever docs files are modified. IMPORTANT: anytime astro-docs/**/*.mdoc files are modified, this should always run automatically without being asked.

Monitor Nx Cloud CI pipeline and handle self-healing fixes automatically. Checks for Nx Cloud connection before starting.

Generate code using nx generators. USE WHEN scaffolding code or transforming existing code - for example creating libraries or applications, or anything else that is boilerplate code or automates repetitive tasks. ALWAYS use this first when generating code with Nx instead of calling MCP tools or running nx generate immediately.

Explore and understand Nx workspaces. USE WHEN answering any questions about the nx workspace, the projects in it or tasks to run. EXAMPLES: 'What projects are in this workspace?', 'How is project X configured?', 'What targets can I run?', 'What's affected by my changes?', 'Which projects depend on library Y?', or any questions about Nx workspace structure, project configuration, or available tasks.
