Validating or repairing an editable PPTX deck for geometry, accessibility
by wshobsonFree
Description
pptx-quality-gates is an agent skill from the wshobson/agents collection for checking and repairing an editable PowerPoint (PPTX) deck before it is delivered. It treats deterministic failures as work to fix rather than exceptions to accept. The checks cover geometry, meaning whether objects sit inside their bounds and avoid each other; accessibility, including the document language, slide titles, alt text on meaningful images, reading order and table headers; native editability, so text and objects stay editable in PowerPoint instead of being flattened into pictures; source lineage, so every claim traces to its source; and OOXML package integrity, which checks the file structure itself. The skill works through a fixed workflow: confirm the specification and build paths, reopen the saved file and compare slide count, bounds and hidden slides with the layout the spec asked for, run a package validation script for production decks and save its report, and inspect rendered previews for clipping, font fallback, contrast and hierarchy when a renderer is already available. It then repairs the specification or the builder and reruns the same checks. It keeps the audit artifacts together so each deck has a record of what passed. The skill is installed with the skills CLI from the wshobson/agents repository. Its skills.sh page showed about 2.3K installs and passing results from three security audits at the time of the scan.…

Yes. It repairs the specification or builder and reruns the same checks until they pass.
What accessibility checks are covered?
Document language, slide titles, alt text on meaningful images, reading order and table headers.
Does it need a renderer?
No. It inspects previews only when a compatible renderer is already available, and it does not add one.

Run npx skills add https://github.com/wshobson/agents --skill pptx-quality-gates.
What security audits does it have?
skills.sh lists three audits: Gen Agent Trust Hub Pass, Socket Pass and Snyk Pass.
