Conciseness

The body is lean: no explanations of concepts Claude already knows, just workflow steps, exact commands, and rules. Not a 5 because the descriptive header rules (e.g., the "Why Flutter?" subtitle examples and anti-patterns) are duplicated between the body and references/blog-format.md, and the heavy bold-caps emphasis (CRITICAL/PROHIBITION/MANDATORY) adds tokens that could be tightened.

Actionability

Guidance is copy-paste executable: `dart run tool/get_video_transcript.dart "<youtube_url>"`, exact output paths, concrete filename examples (`content/showcase/bmw.md`, `global_citizen_logo.png`), and explicit frontmatter field rules (`successMetrics` must include `perc` and `desc`, `publishDate`, embed URL formatting).

Workflow Clarity

Four clearly numbered, sequenced steps (extract transcript → analyze & generate → image assets → output & YAML update) with interactive checkpoints (prompt for URL, wait for the user-attached image). Not a 5 because there is no explicit validation/verification step for the final output (e.g., confirming the frontmatter is well-formed or the image paths resolve) — a minor validation gap rather than the missing-loop pattern that would cap at 3, since the operations are additive rather than destructive.

Progressive Disclosure

The body is a concise workflow overview that delegates detailed format/tone guidance to a single, well-signaled, one-level-deep reference (references/blog-format.md, linked twice with markdown links), and the file exists in the bundle. Navigation is easy and the split is appropriate; the small overlap in header-format rules reads as deliberate emphasis of critical constraints.

Specificity

"Extracts YouTube transcripts and generates professional Flutter showcase blog posts in Markdown format" lists two specific concrete actions with a clearly named domain (YouTube, Flutter, Markdown). Not a 5 because the description omits parts of the pipeline the body performs (image asset handling, companies.yaml update), leaving minor gaps in coverage.

Completeness

Both parts are explicitly answered: the "what" ("Extracts YouTube transcripts and generates professional Flutter showcase blog posts in Markdown format") and the "when" ("Use when you need to create a technical marketing case study from a video success story"). Not a 5 because the trigger is a single phrase rather than multiple concrete trigger phrasings users might use.

Trigger Term Quality

Natural terms users would say are present: "YouTube transcripts", "case study", "blog post", "video success story", "Flutter showcase". Not a 5 because a few common variations and synonyms (e.g., "customer story", "write a post from a video", "marketing content") are missing.

Distinctiveness Conflict Risk

The niche is clear and narrow — Flutter showcase blog posts generated from video transcripts — with distinct triggers ("technical marketing case study from a video success story") and minimal overlap risk with other skills.
