What it does

PPTX is an agent skill from HybridAIOne/hybridclaw. Create and edit .pptx presentations safely, export thumbnails for QA, and build polished decks with pptxgenjs plus OOXML editing.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `editing.md` and `pptxgenjs.md`).

It sits in Documents & Office, covering PowerPoint presentations. It works with Microsoft PowerPoint, python-pptx and LibreOffice. The repository describes itself as: Enterprise-ready self-hosted AI assistant runtime with sandboxed execution, secure credentials, approvals, and memory. The licence is MIT.

When your agent uses it

  • Tasks that involve PowerPoint presentations

Example prompts

  • “/pptx”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Export the deck to PDF
  2. Render slide thumbnails
  3. Delegate the visual inspection
  4. Apply only the concrete fixes found by review, then rerun the render and inspection steps.
  5. Stop when there are no concrete slide-level issues left, or when one more rerender produces the same findings and further iteration would…

What it can do on your machine

Read from SKILL.md and the folder at commit 3624072. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • sh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

PPTX loads about 1k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

PPTX

Use this skill whenever the user asks to create, revise, template, or review a .pptx presentation.

Start Here

Working Rules

  • For template-based editing, use unpack -> edit OOXML -> pack. Do not round-trip an existing deck through pptxgenjs.
  • For new decks, use pptxgenjs from a CommonJS .cjs script with require("pptxgenjs").
  • For new decks built from a folder of source files, treat the named source documents as the inputs of record. Do not inspect older generated decks, dashboards, summary files, or helper scripts in that folder unless the user explicitly asks to reuse or update them.
  • Use node skills/office/soffice.cjs convert ... --format pdf only when the runtime says soffice is available.
  • Keep layouts intentional: one message per slide, strong hierarchy, real whitespace, and consistent alignment.
  • Use speaker-ready phrasing and evidence-based charts instead of generic bullet walls.
  • For pptxgenjs tables, never use OOXML values directly in script options. Do not use valign: "mid", valign: "ctr", or raw anchor: "mid". If vertical alignment is needed, use only the pptxgenjs values top, middle, or bottom. If it is not essential, leave table-cell vertical alignment unset.
  • After pptx.writeFile(...) succeeds and the requested deck exists at the expected path, return it immediately. Do not inspect your own generated script or rerun file-existence checks unless generation failed or the user asked you to debug the deck.

Visual QA Loop

  • If both soffice and pdftoppm are available in the runtime, visual QA is required before final delivery.
  • If either dependency is unavailable, do not attempt the render-and-review loop. Return the generated .pptx without mentioning the missing QA tools unless the user explicitly asked for QA, export, thumbnails, validation, or render verification.
  1. Check capability availability before starting the QA loop. Prefer the runtime capability system message if it is already present. If you need to verify manually, run:
bash
sh -lc 'command -v soffice >/dev/null 2>&1 || command -v libreoffice >/dev/null 2>&1'
sh -lc 'command -v pdftoppm >/dev/null 2>&1'

Only continue with steps 3-6 when both commands succeed. 2. Export the deck to PDF:

bash
node skills/office/soffice.cjs convert deck.pptx /tmp/pptx-export --format pdf --json
  1. Render slide thumbnails:
bash
node skills/pptx/scripts/thumbnail.cjs deck.pptx /tmp/pptx-thumbs --count 6 --json
  1. Delegate the visual inspection:
json
{
  "mode": "single",
  "label": "PPTX QA",
  "prompt": "Review the generated slide thumbnails in /tmp/pptx-thumbs. Check alignment, overflow, contrast, chart legibility, and whether each slide communicates a single clear idea. Summarize concrete slide-by-slide fixes."
}
  1. Apply only the concrete fixes found by review, then rerun the render and inspection steps.
  2. Stop when there are no concrete slide-level issues left, or when one more rerender produces the same findings and further iteration would just churn.

Templates

  • Prefer user-provided templates from the current workspace or mounted paths.
  • Bundled starter templates can live under skills/office/templates/.
  • When a template defines brand layouts, preserve its masters, layouts, and theme parts unless the user explicitly asks for a redesign.

Can I use PPTX in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add HybridAIOne/hybridclaw --skill pptx -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pptx, .gemini/skills/pptx, .github/skills/pptx and .opencode/skills/pptx in your project.

What does PPTX need to run?

Going by SKILL.md and its folder, PPTX needs JavaScript for the scripts in its folder and the command-line tools its instructions call (node and sh).

Does PPTX access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is PPTX safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does PPTX use?

PPTX is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does PPTX use?

About 1k tokens (SKILL.md is roughly 4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
