A PowerPoint workflow for creating, inspecting, editing, checking, rendering, and delivering .pptx presentations and .potx templates. It preserves the presentation's internal structure and user metadata.

Use it to build slide decks, edit existing presentations, duplicate or remove slides, convert supported .ppt files, and check the final rendering.

It helps avoid damaged layouts, missing presentation parts, and unnoticed rendering problems when changing slide files.

pptx — Skill for Claude Code and Codex by MemTensor/memmy-agent

About the project

Memmy is a local memory hub that gives multiple AI agents one shared, persistent context about their user. It helps people continue work across agents such as Claude Code, Codex, OpenClaw, and Hermes Agent. The catalogue entries are skills for using Memmy with supported agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00813
Opus 5.5	$0.00012	$0.00325
Sonnet 5.5	$0.00006	$0.00163
Haiku 4.5	$0.00003	$0.00081

Security

Grade A, and why

pptx 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 25d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/check_deck.mjs, scripts/clone_slide.mjs, scripts/make_contact_sheet.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPTX workflow

Use this skill whenever the input or requested output is a .pptx or .potx presentation, slide deck, template, slide layout, speaker notes, comments, or slide conversion. It is not a replacement for ordinary document or image editing.

Decide the operation

For a new deck, create one pptxgenjs presentation, set its layout before adding slides, and keep charts and tables editable.
For an existing deck, copy it to a private temporary directory first. Use scripts/inspect-style OOXML inspection through the checkers, then edit only requested parts with jszip and XML parsing.
To duplicate a slide use scripts/clone_slide.mjs; do not copy one XML file by hand. To remove unused parts use scripts/prune_orphans.mjs only after the final slide order is established.
For .ppt input, convert a temporary copy with scripts/render_with_office.mjs --headless --convert-to pptx when the bundled Office payload supports it. Conversion failure is a hard failure.

Required quality sequence

Work in a unique temporary directory and leave the source unchanged.
Make all slide additions, deletions, and ordering changes.
Fill content while preserving theme, notes, comments, media, charts, embedded objects, hidden slides, and user metadata.
Run scripts/check_deck.mjs <deck-or-directory> --json; pass --baseline <template> only for a template baseline. Use --auto-repair only for the safe ID/relationship repairs reported by the checker.
Render with scripts/render_with_office.mjs --headless --convert-to pdf <deck> --output-dir <dir> and inspect every page. Create a grid with scripts/make_contact_sheet.mjs --input <deck> --output-dir <dir> --prefix <unique-name> when a compact review is useful.
Reopen the output with the checker and confirm page count, notes, media, charts, hidden slides, and metadata before delivery.

Design and content checks

Set a deliberate 16:9 or standard layout before adding slides. Use six-digit hex colors without alpha in the color field, native bullets, speaker notes, and editable charts. Keep text left aligned, provide at least 0.5 inch safe margins, and avoid overflow, overlap, low contrast, placeholder text, and decorative edge bars. Typical sizes are 36–44 pt titles, 20–24 pt section titles, 14–16 pt body, and 10–12 pt notes. Font choice and any cross-platform rendering difference must be recorded in the QA report.

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.

pptx is a skill published in the GitHub repository MemTensor/memmy-agent (2,102 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 813 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-21.
