The body is lean and assumes Claude's competence — it never explains what Nx or a workspace is, and every line (including the package-manager prefix note) earns its place without padding.

It provides copy-paste-ready executable commands ("nx run <project>:<task>", "nx run-many -t build test lint typecheck", "nx affected -t build test lint") plus concrete flag examples, fully matching the executable anchor.

Sections are clearly organized (understand → single → multiple → affected → flags), but the batch operations (run-many, affected) lack any validation/verification guidance such as checking exit codes or handling partial failures, which caps batch workflows at 2.

With no bundle files present and under 50 lines, the well-organized section headers (Understand which tasks, Run a single task, Run multiple tasks, Run tasks for affected projects, Useful flags) satisfy the simple-skill allowance for a top score.

It names the domain ("running tasks in an Nx workspace") and enumerates concrete task types ("build, test, lint, serve, or run any other tasks"), but the action itself ("running") is a single verb rather than multiple distinct actions, so it stops short of anchor 3.

It explicitly answers both what ("Helps with running tasks in an Nx workspace") and when ("USE WHEN the user wants to execute build, test, lint, serve, or run any other tasks"), matching the anchor for clearly answering both.

The trigger lists natural task terms users say ("build, test, lint, serve"), but the terms are generic across build tooling and omit common Nx-specific variations (e.g., "nx", "monorepo", "run task"), leaving some coverage gaps.

The "Nx workspace" framing gives it a niche, but the generic task triggers (build, test, lint, serve) could overlap with non-Nx build-tooling skills, so it is not yet at the clear-niche anchor 3.
