Decision brief
What it does—and where it fits
Author final coordinates directly in layouttree. No renderer may decide placement, shrink text, or infer layout after the audit.
Not for
- Tasks that require unconfirmed production actions or broad system permissions.
- Environments where the pinned source and install steps cannot be inspected.

Inspect the Agent Skill "pptx-slide-specification" from https://github.com/wshobson/agents/blob/c4b82b0ad771190355eb8e204b1329732a18449a/plugins/pptx-deck-creation/skills/pptx-slide-specification/SKILL.md at commit c4b82b0ad771190355eb8e204b1329732a18449a. List every install step, command, network request, credential, file read/write, external action, and rollback step. Explain whether it fits my task. Do not install or execute anything until I approve.

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
summaryandslides. - Every slide has a stable
id, a message-ledtitle, an accessibility reading order, and a completelayout_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, andz_index. - Production
summarycontains an explicitlayout_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_designobjects may be full bleed. - Use native
text,shape,line,table, andimageobjects. Recreate labels and values from any supporting visual as native objects. - Give meaningful images alt text. Record
source_reffor 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.
