The description mentions creating a Power Pages code site (SPA) using specific frameworks (React, Angular, Vue, Astro), which names the domain and some actions, but it doesn't list multiple concrete actions beyond 'create/scaffold'. It lacks detail on what the skill actually does (e.g., generates project structure, configures routing, sets up build tools).

The 'when' is very well covered with explicit trigger phrases, but the 'what' is weak — it only says 'create a new Power Pages code site' without describing what concrete outputs or steps the skill performs. The description is almost entirely trigger-focused with minimal capability explanation.

Excellent coverage of natural trigger terms: 'create a power pages site', 'build a code site', 'scaffold a website', 'create a portal', 'make a new site', plus framework names (React, Angular, Vue, Astro) and the term 'SPA'. These are phrases users would naturally say.

The description is highly distinctive with 'Power Pages code site (SPA)' as a clear niche. The combination of Power Pages + specific frameworks makes it very unlikely to conflict with generic web development or other site-building skills.

This skill is extremely verbose at ~500+ lines. It over-explains many concepts Claude already understands (git commands, what CSS variables are, how to use npm install, what alt text is). Tables explaining common accessibility fixes, lengthy phase descriptions with repeated gate conditions, and extensive example workflows all contribute to significant token waste. Much of this could be condensed to 40-50% of its current size.

The skill provides highly specific, executable commands (git init, npm install, npm run dev), exact file paths with template variables, concrete Playwright verification steps, specific axe-core audit commands with flags, and detailed tables mapping violations to fixes. Code blocks are copy-paste ready with proper variable substitution patterns.

The 8-phase workflow is meticulously sequenced with explicit GATE conditions that must be met before proceeding (e.g., Phase 2 gate requires 6 specific conditions). Validation checkpoints are built into every phase — Playwright verification after changes, axe-core re-runs after fixes, git commits for rollback capability. Error recovery is addressed (git revert, re-verify loops).

The skill references external files well (design-aesthetics.md, framework-conventions.md, skill-tracking-reference.md, template asset directories), but the main SKILL.md itself is monolithic — all 8 phases with full detail are inline rather than being split into separate reference files. The example workflow at the end duplicates information already covered in the phases. Content like the accessibility fix table and detailed git instructions could be in separate references.
