pptx-slide-specification

pptx-slide-specification is a skill for Claude Code, Codex from kimtth/agent-pptify-kit. It costs 25 tokens per session (426 once invoked), scanned A, original, MIT.

A specification format for placing every element of an editable PowerPoint deck with explicit coordinates. Each slide records its content, layout tree, styles, accessibility order, dimensions, and visual roles in JSON.

In plain words
What is it for?
Use it when creating or repairing coordinate-based PPTX slide specifications, including native text, shapes, tables, lines, images, accessibility metadata, and source references.
Why use it?
It prevents later tools from guessing positions, shrinking text, or changing the audited layout, which supports predictable slide rendering and editing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pptx-slide-specification scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

PPTX Slide Specification

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

  1. Use stable readable IDs, absolute groups, and positive inch dimensions.
  2. Keep normal content inside the safe margin and above the footer rail. Only background layout_design objects may be full bleed.
  3. Use native text, shape, line, table, and image objects. Recreate labels and values from any supporting visual as native objects.
  4. Give meaningful images alt text. Record source_ref for sourced claims.
  5. Keep content text at 9 pt or greater; shorten, resize, or split dense content before reducing type.
  6. 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.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
