The body is a lean topic index of one-line reference pointers plus a few concrete rules; it assumes Claude's competence and avoids explaining concepts Claude already knows, fitting the lean 3 anchor rather than the padded 2 anchor.

Provides fully executable commands (npx @angular/cli@<version> new, ng version, ng new, ng build) and concrete anti-patterns with specific fixes (e.g. form.field().valid() vs form.field.valid), matching the copy-paste-ready 3 anchor.

The ng new workflow is a clear IF/THEN sequence (Step 1–3) with an explicit ng build validation checkpoint and fix-before-proceeding feedback loop, matching the 3 anchor with validation and error recovery.

SKILL.md is a concise overview pointing to ~35 real, one-level-deep reference files organized by topic with descriptive labels and links; all referenced paths exist in references/, matching the clear-overview 3 anchor.

Lists multiple specific concrete actions — "Generates Angular code and provides architectural guidance" plus "creating projects, components, or services" — matching the multi-action anchor rather than the single-domain anchor at 2.

Explicitly answers both what ("Generates Angular code and provides architectural guidance") and when ("Trigger when creating projects, components, or services..."), matching the 3 anchor with an explicit trigger clause.

Covers natural developer terms users would actually say ("signals, linkedSignal, resource", "forms", "routing", "SSR", "accessibility (ARIA)", "Tailwind CSS", "testing", "CLI tooling"); not merely technical jargon, so it sits above the 2 anchor.

Clearly Angular-specific niche with distinct, framework-scoped triggers unlikely to fire for unrelated skills; above the 2 anchor which still risks overlap.
