Conciseness

No padding explaining what PDFs or tesseract are; the body is dense tables of commands, tuned flags, and justifications Claude would not know (e.g., '200 loses accuracy on small/serif text; 600 doubles file size'). Not 5 because a few tokens could be trimmed — the '~8 min serial to ~1–2 min' benchmark anecdote and some chatty 'Why' column phrasing.

Actionability

Fully executable throughout: a complete copy-paste bash script with set -euo pipefail, mktemp + trap cleanup and parallel xargs; exact flags (-r 300, --psm 1, -l eng+fra); install commands; and one-liners for every output format (txt, pdf, hocr, tsv). Covers all common cases.

Workflow Clarity

The full pipeline is clearly sequenced (detect scan → tool-selection flowchart → numbered render/OCR/concatenate recipe → validation) with an explicit checkpoint: 'Sample 3–5 random pages before trusting bulk output', plus red flags and concrete remediation (raise DPI to 400, change --psm, fix -l, pre-rotate with mogrify). This is a batch operation that DOES have validation and feedback loops, so the workflow cap does not apply.

Progressive Disclosure

A single well-organized file with clear section headers, a quick-pattern lookup table, and a well-signaled internal anchor link; no bundle files exist and nothing (large API reference, deep detail) needs splitting out. Not 5 because the under-50-line simple-skill exception does not apply at ~135 lines, and all content — including installation and gotchas — is inlined with no external references.

Specificity

Names concrete inputs ("scanned PDFs and image files"), output ("searchable text"), and exact tools ("pdftoppm + tesseract (or ocrmypdf)"), which goes beyond anchor 3's minimal actions. Not 5 because coverage has gaps — the skill also produces searchable PDFs and standalone image OCR variants that the description does not enumerate.

Completeness

Explicitly answers both: what ("OCR scanned PDFs and image files into searchable text using pdftoppm + tesseract") and when ("Load when about to OCR a scanned PDF or image, or when extracted PDF text is empty/garbled") with concrete trigger phrases. Clear match for anchor 5; anchor 4's 'when could be more explicit' criticism does not apply.

Trigger Term Quality

Includes natural phrases users would say — "OCR", "scanned PDF", "image", "extracted PDF text is empty/garbled". Not 5 because it omits file extensions (.pdf, .png, .jpg) and common synonyms like "scanned document" or "searchable PDF".

Distinctiveness Conflict Risk

OCR of scanned documents is a clear niche with distinct triggers, and the empty/garbled-text trigger is precisely scoped to the OCR fallback case rather than general PDF work. Minimal conflict risk with adjacent PDF-manipulation skills.
