What does this skill do, and when should you use it?
This is an AI-agent skill for building PowerPoint presentations, built on python-pptx. It ships with hand-polished Chinese PPTX templates (17 per the repo description and README; SKILL.md says 21) and lets the agent pick pages, write an edits. of text replacements, and produce a genuine .pptx without touching shape positions, colors, or font sizes. It also supports non-destructive text-only editing of user-supplied .pptx templates, plus fully original minimalist layouts. Built-in safeguards include text-box overflow detection and same-level title font-size consistency checks. Note: personal and research use only — commercial use is strictly forbidden.
- Reads templates/INDEX.md plus each template's intro.md and detail. to match and select a template
- Takes slide selections and text replacements from edits. and runs scripts/build_pptx.py to produce the final .pptx, with overflow-detection warnings
- Runs scripts/render_slides.py (LibreOffice + pdftoppm) to render each slide to PNG for preview and self-checking
- scripts/check_update.py and apply_update.py provide incremental git-based auto-updates
- build_pptx.py --chart-data updates native PPT chart data
- compute_capacity.py computes per-slot capacity fields when adding new templates
- A professional needs a work report, year-end summary, or quarterly review deck and picks a built-in template, filling in their own content
- A student preparing a thesis proposal defense or book report wants a polished, information-dense final PPTX
- A user has their company's .pptx template and wants the AI to generate a new deck from it without breaking the layout
- A user wants to change only some text in an existing deck, keeping layout, colors, and font sizes untouched
- Someone needs teaching slides or a business proposal and wants to compare template previews before choosing
- A user explicitly asks for a clean original design with no template
- Any commercial use (business presentations, sales, training distribution, client proposals) — templates are from third-party designers, commercial reuse is forbidden, and the repo has no LICENSE file
- Situations requiring decorative graphics (progress bars, rings, flow arrows) to sync with percentage text — the graphics do not update
- Linux users who cannot configure a fontconfig alias or lack LibreOffice and poppler — Microsoft YaHei is required and preview rendering will not work
How do you install this skill?
- Auto-pulls and runs a remote update script on first use each session — effectively trusting code the maintainer can push at any time; weigh this supply-chain risk yourself
- Shell / CLI
- Network access
- Local filesystem
Python 3 with python-pptx 1.0+LibreOffice (only for preview rendering)poppler/pdftoppm (only for preview rendering)Microsoft YaHei font or a fontconfig alias to WenQuanYi Micro Hei / DengXian / Noto Sans SC / PingFang SC
The repo documents no automated installer. Per the README, you simply prompt your agent: "Install this Skill: https://github.com/GordenSun/GordenPPTSkill". Dependencies: python-pptx 1.0+; LibreOffice and poppler are additionally needed only for preview rendering. If Microsoft YaHei is missing, configure a fontconfig alias (an XML example is in the README).
Any Agent: on first use in a session, run:
python3 scripts/apply_update.pyHow do you use this skill?
Once installed, send your agent any of these to trigger it:
- Make me a year-end work summary deck using one of the built-in templates
- Use our company's .pptx file as the template and generate a new quarterly review deck from it
- Change only the titles and body text on slides 3 and 7, keeping the layout and colors untouched
- Create a clean original teaching slide deck without using any template
Standard flow: 1) pick a template from templates/INDEX.md (if unspecified, the skill should offer exactly 3 candidates with preview images for you to choose); 2) read the template's intro.md and detail.; 3) write edits. with template_slug, selected_slides, and per-slot text replacements; 4) run python3 scripts/build_pptx.py <template.pptx> edits. out/final.pptx --detail <detail.> (do not use --strict); 5) optionally run python3 scripts/render_slides.py out/final.pptx out/renders --dpi 144 to preview. Example trigger prompt: "Use this Skill to make a 2026 annual review deck." Editing rules include: replace all placeholder text, never truncate with ellipses, keep same-level titles at the same font size, and never modify the user's original template file.
What are this skill's strengths and limitations?
- Rich Chinese-scenario template library covering reports, summaries, defenses, proposals, and courseware
- Text-only, layout-preserving editing guarantees output matches the template's visual design
- Built-in overflow detection and same-level title font-size consistency checks reduce layout accidents
- Supports user-supplied templates and native chart data updates; README claims it was tested with DeepSeek, Xiaomi MiMo, Claude, and GPT
- Incremental auto-update mechanism keeps templates current
- Strictly non-commercial; templates come from third-party designers and commercial reuse requires the original authors' permission
- Decorative graphics (progress bars, rings, flow arrows) do not sync when you change percentage text
- Template count is inconsistent between the README (17) and SKILL.md (21), suggesting stale docs
- Depends on the Microsoft YaHei font — Linux users must configure a fontconfig alias; preview rendering requires LibreOffice and poppler
- No LICENSE file (NOASSERTION), so rights are ambiguous
- No automated test suite; output quality depends on the templates and how well the agent follows the rules

How did FollowSkills review this skill?
Mandates auto-running `python3 scripts/apply_update.py` on first use each session, pulling and applying remote update files — a self-update mechanism where the user unknowingly fetches and runs code the maintainer can change at any time, a real supply-chain trust concern.
The bundled templates explicitly state personal/research use only, no commercial use, since they're third-party designer work — the license boundary is stated clearly.
