PPTX Deck Creation

Chapter 124 of 180

PPTX Slide Specification

Use when authoring or repairing a coordinate-explicit JSON specification for an editable PPTX deck.

1 minute · 232 words · 3 sections

Author final coordinates directly in layout_tree. No renderer may decide placement, shrink text, or infer layout after the audit.

Required contract

The root JSON contains summary and slides.
Every slide has a stable id, a message-led title, an accessibility reading order, and a complete layout_tree.
A layout tree declares slide size, root group, id-keyed groups and objects, final inch bboxes, styles, z-indexes, and classifications.
Every meaningful object has id, kind, role, classification, content, style, bbox, and z_index.
Production summary contains an explicit layout_policy (safe margin, content bottom, footer top, minimum gap) and accessibility metadata.

Authoring rules

Use stable readable IDs, absolute groups, and positive inch dimensions.
Keep normal content inside the safe margin and above the footer rail. Only background layout_design objects may be full bleed.
Use native text, shape, line, table, and image objects. Recreate labels and values from any supporting visual as native objects.
Give meaningful images alt text. Record source_ref for sourced claims.
Keep content text at 9 pt or greater; shorten, resize, or split dense content before reducing type.
Use shared grids, consistent gaps, explicit color, explicit font size, and an intentional z-order.

Build contract

A task-local builder starts from a blank slide layout and maps all bboxes with Inches(...). Explicitly set wrapping, disabled auto-size, text insets, anchors, alignment, fonts, colors, line settings, image aspect ratio, and hidden-slide state. Reject zero or negative geometry before adding an object.

See references/layout-contract.md for the compact schema and repair guidance.

Install this repository

Skills install per repository, not per chapter — the CLI has no documented per-skill form, so we do not print one.

Typesetting note

Removed “PPTX Slide Specification”, a leading h1 that duplicated the chapter title.

How this issue was made

Source

github.com/wshobson/agents, branch main, last pushed 5 August 2026.

Licence

MIT — the text of every chapter is reproduced unmodified, frontmatter included, under the upstream licence.

Discovery

180 chapters found by walking the repository tree for SKILL.md, not by matching a directory convention. 49 distinct layouts observed: plugins/accessibility-compliance/skills/*/SKILL.md, plugins/agent-teams/skills/*/SKILL.md, plugins/api-scaffolding/skills/*/SKILL.md, plugins/backend-development/skills/*/SKILL.md, plugins/before-you-build/skills/*/SKILL.md, plugins/block-no-verify/skills/*/SKILL.md, plugins/blockchain-web3/skills/*/SKILL.md, plugins/brand-landingpage/skills/*/SKILL.md, plugins/business-analytics/skills/*/SKILL.md, plugins/cicd-automation/skills/*/SKILL.md, plugins/cloud-infrastructure/skills/*/SKILL.md, plugins/conductor/skills/*/SKILL.md, plugins/data-engineering/skills/*/SKILL.md, plugins/database-design/skills/*/SKILL.md, plugins/developer-essentials/skills/*/SKILL.md, plugins/dgx-spark-ops/skills/*/SKILL.md, plugins/documentation-generation/skills/*/SKILL.md, plugins/documentation-standards/skills/*/SKILL.md, plugins/dotnet-contribution/skills/*/SKILL.md, plugins/file-conversion/skills/*/SKILL.md, plugins/framework-migration/skills/*/SKILL.md, plugins/frontend-mobile-development/skills/*/SKILL.md, plugins/game-development/skills/*/SKILL.md, plugins/hermes-tweet/skills/*/SKILL.md, plugins/hr-legal-compliance/skills/*/SKILL.md, plugins/incident-response/skills/*/SKILL.md, plugins/javascript-typescript/skills/*/SKILL.md, plugins/kubernetes-operations/skills/*/SKILL.md, plugins/llm-application-dev/skills/*/SKILL.md, plugins/llm-finetuning/skills/*/SKILL.md, plugins/machine-learning-ops/skills/*/SKILL.md, plugins/observability-monitoring/skills/*/SKILL.md, plugins/payment-processing/skills/*/SKILL.md, plugins/plugin-eval/skills/*/SKILL.md, plugins/pptx-deck-creation/skills/*/SKILL.md, plugins/protect-mcp/skills/*/SKILL.md, plugins/python-development/skills/*/SKILL.md, plugins/quantitative-trading/skills/*/SKILL.md, plugins/reverse-engineering/skills/*/SKILL.md, plugins/review-agent-governance/skills/*/SKILL.md, plugins/security-scanning/skills/*/SKILL.md, plugins/shell-scripting/skills/*/SKILL.md, plugins/ship-mate/skills/*/SKILL.md, plugins/signed-audit-trails/skills/*/SKILL.md, plugins/skill-forge-essentials/skills/*/SKILL.md, plugins/social-publishing/skills/*/SKILL.md, plugins/startup-business-analyst/skills/*/SKILL.md, plugins/systems-programming/skills/*/SKILL.md, plugins/ui-design/skills/*/SKILL.md.

Issue colours

Resolved from a deterministic hash of the owner name. Two accent tones are generated per issue and each is proven against its own ground before it ships: a single accent that passes AA on both light and dark paper is arithmetically impossible.

Heading repairs

1 repair applied to this chapter so the document has one h1 and no skipped levels:

Removed “PPTX Slide Specification”, a leading h1 that duplicated the chapter title.

Spec compliance

1 editorial note across 1 of 180 chapters. They are printed in the margin of each chapter rather than as errors here.

PostgreSQL Table Design — 1 note

Images

Images inside a chapter come from the upstream repository. Where the author gave no alternative text we mark the image decorative rather than inventing a description — a plausible caption we made up is worse than none for the reader who depends on it.

Marketplace

A plugin manifest is published at .claude-plugin/marketplace.json by Seth Hobson, declaring 95 plugins. It is read for editorial metadata only — never as the skill index, which is always the repository tree.

Signal

Install counts come from skills.sh. They measure downloads, not quality, and an unranked repository is not an unread one.

Agent surfaces

The whole issue is available as one markdown document at /wshobson/agents.md, and each chapter at its own .md URL.

Publication

Set by Skills Docs from the source repository. Body text is Literata at the reader’s chosen size and measure; code is Geist Mono. Nothing on this page was written by us except this paragraph.
