Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00052 | $0.01125 |
| Opus 5.5 | $0.00021 | $0.00450 |
| Sonnet 5.5 | $0.00010 | $0.00225 |
| Haiku 4.5 | $0.00005 | $0.00112 |
Grade A, and why
presentations 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 today.
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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Presentations
The durable artifact is the default working deck. It is the same live object the user sees in the Artifacts dock and slide editor. Never maintain a mutable PPTX shadow or publish a sandbox deck over user edits. The exception is a file the user sends to be changed, or a requested file format the artifact cannot export; see "Requested PowerPoint files" below.
Read references/api.md before editing.
When using skill_read, request that relative path from this Skill; reading
does not materialize a local folder. Use an existing local copy only when the
Skill was installed or explicitly checked out to the filesystem.
Choose the canonical object
- If the user means “this deck” or a visible presentation, call
opengeni__editable_artifact_list, thenopengeni__editable_artifact_getwhen needed. Do not guess from chat text. - To begin empty, call
opengeni__editable_artifact_createwith modalitypresentation. - To begin from a ready workspace PPTX, call
opengeni__editable_artifact_importwith itsfileId. The source remains immutable provenance; the returned artifact becomes the working deck. - Use a standalone local PPTX only when the user explicitly asks to manipulate
sandbox-local bytes and the pinned local runtime is actually available.
Normal import/export uses workspace
fileIdboundaries without local bytes.
Requested PowerPoint files
When the user sends a PowerPoint file to be changed and returned, or asks for a
new PowerPoint file while opengeni__editable_artifact_export is unavailable or
does not list that format, the file itself is the deliverable:
- Make or edit it in the sandbox with ordinary tools (
python-pptx; LibreOffice (soffice --headless --convert-to pdf) for a PDF copy). Install a missing package withpip install <package>if needed. - When editing a sent file, open the original and change only what was asked, keeping its other content, formatting and objects.
- Read the result back to check the content.
- Publish the file and reply with a short summary and its link. Do not also build a native artifact of the same content.
What ships with it
2 files 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.
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.

presentations is a skill published in the GitHub repository Cloudgeni-ai/opengeni (205 stars, last pushed today), licensed Apache-2.0. It adds 52 tokens to every session and 1,125 once invoked, about $0.0002 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 2026-10-21.
Other skills, from other repositories
generative-ui
Use when presenting information already in hand as a small, static structured panel in the conversation — status, results, comparisons, or a compact summary — rather than prose, a markdown table, a widget, or an app.
st-widget-builder
Use when the user asks to render, build, visualise, mock up, or show a widget (chart, dashboard, card, table, graph) in the Mewbo Console. Teaches how to delegate the work to the st-widget-builder sub-agent instead of writing HTML or inline code yourself.
pn-render-verify
Re-read a rendered or visual artifact and produce a structured verdict against the spec. Use before pn-skeptic-challenge in design workflows when the deliverable is a render, image, screenshot, or HTML page.
pn-animation
Motion roles (Reveal/Orient/Confirm/Delight) and budgets. Use when designing or auditing a motion system — load pn-gsap for GSAP API.
pn-design-variants
Generate 3+ radically different designs or API interfaces in parallel using sub-agents, then compare and synthesize. Based on "Design It Twice" from A Philosophy of Software Design. Use before committing to a single design approach — for UI layouts, component APIs, module interfaces, or system architecture choices.
pn-color-system
Color system design and implementation: OKLCH color space, tinted neutrals, palette structure, contrast, dark mode architecture, and token hierarchy. Use when establishing color tokens, theming, dark mode, or reviewing color choices.
