opengeni: Skill for Codex

.agents/skills/opengeni-presentations/SKILL.md

opengeni-presentations is a skill for Codex from Cloudgeni-ai/opengeni. It costs 58 tokens per session (870 once invoked), scanned A, original, Apache-2.0.

A toolkit for creating, inspecting, editing, importing, and exporting OpenGeni presentations, including slides, layouts, text, tables, charts, media, and notes.

In plain words
What is it for?
Use it to build or modify slide decks, import a presentation, manage its content, and prepare or inspect PPTX files.
Why use it?
It keeps the editable presentation as the main working document and provides checks for the slide structure and visual result.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is Cloudgeni-ai/opengeni's own configuration. It tells Codex how to work on opengeni itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything opengeni configures →

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.

Security

Grade A, and why

opengeni-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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenGeni presentations

The durable OpenGeni 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.

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, then opengeni__editable_artifact_get when needed. Do not guess from chat text.
  • To begin empty, call opengeni__editable_artifact_create with modality presentation.
  • To begin from a ready workspace PPTX, call opengeni__editable_artifact_import with its fileId. 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 fileId boundaries without local bytes.

Edit and verify

  1. Inspect metadata and the slide catalog. Before changing a slide, inspect its complete bounded editor scene, including inherited layout facts and notes.
  2. Plan the narrative and visual system before creating many nodes. Preserve an imported master/layout hierarchy; do not flatten the deck.
  3. Make the smallest coherent edit. One opengeni__editable_artifact_apply call is one atomic command batch. Use inspected ids for existing objects and openGeni.artifacts.ids.stable() for every new master, layout, slide, or node. A direct call must pass the inspected headSequence and stateHash; CodeMode carries its last read head automatically.
  4. For one simple edit, call the artifact tools directly. For loops, generated ids, slide construction, or several inspections, write auditable Bun code using openGeni.artifacts from @opengeni/codemode. Both paths execute the exact same frozen tools and authorization.
  5. Inspect every affected slide after mutation. Reconcile bounds, paint order, text, chart/table data, notes, and inheritance. If concurrent work invalidates an assumption, re-inspect and recompute; never force a stale rewrite.
  6. Export only when the user needs PPTX/PDF/image delivery or visual QA. opengeni__editable_artifact_export_status returns a durable workspace fileId; it does not write into the sandbox. Download only when local bytes are actually needed.

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.

opengeni-presentations is a skill published in the GitHub repository Cloudgeni-ai/opengeni (126 stars, last pushed today), licensed Apache-2.0. It adds 58 tokens to every session and 870 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
