okra-create — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited okra-create (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

One Worker, three modes to produce designed PDFs:
type (report, magazine, editorial, poster…) and send content blocks. Container renders body in Python (reportlab), Browser Rendering renders the cover, Worker merges.pdf.render + browser.htmlToPdf + pdf.merge in one request. Custom cover + baked body in a single call.[minimax-pdf]: https://skills.sh/minimax-ai/skills
Request → Worker

├─ DO Container (Python: palette → cover-html → body → merge)

}Non-negotiable template rules (see templates/editorial-hero.html):
@page { size: 794px 1123px; margin: 0; } — locks PDF page dims.html, body { width: 794px; height: 1123px; overflow: hidden; } — viewport anchor.grid-template-columns: minmax(0, 1fr) 220px; — the minmax(0, …)prevents content from expanding a flexible column past its share.
overflow: hidden on the page container — last-line defense against bleeds.@import Google Fonts at the top; Worker uses waitUntil: "domcontentloaded"(not networkidle0 — fonts can stall that).
See templates/editorial-hero.html for a working magazine-cover reference.

Browser Rendering hangs on first call.
keep_alive on puppeteer.launch() or waitUntil: "networkidle0" with @imported fonts.puppeteer.launch(env.BROWSER, { keep_alive: 600000 }) + setContent(html, { waitUntil: "domcontentloaded" }).Content clips on the right edge of the PDF.
setContent; Chrome used its default viewport, layout math didn't match PDF size.page.setViewport({ width: 794, height: 1123 }) before setContent; page.pdf({ width: "794px", height: "1123px" }).Table cells wrap digits like `90.74` → `90.7 / 4`.
col_widths fraction too small for the numeric precision."specialized" wraps as "specializ/ed" in table rows.
Reportlab justification stretches short paragraphs.
body block is full-justified. For closing 1-2 sentence paragraphs, fold into the previous body block or accept the rivering.Trailing caption block orphans to a nearly-empty last page.
