Tlamatini: Skill for Codex

.codex/skills/overlap-safe-pptx-dossier/SKILL.md

overlap-safe-pptx-dossier is a skill for Codex from XAIHT/Tlamatini. It costs 66 tokens per session (1,307 once invoked), scanned A, original, MIT.

A set of rules for creating complete PowerPoint technical decks with safe layouts. It covers slide structure, diagrams, tables, file trees, and checks that content stays within slide boundaries without unintended overlap.

In plain words
What is it for?
Use it when building or updating technical PPTX presentations that need architecture explanations, usage instructions, file inventories, complete project trees, tables, and diagrams.
Why use it?
It helps prevent crowded slides, clipped content, and text or graphics covering one another. It is intended for decks that document an entire software system.

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

overlap-safe-pptx-dossier 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 12d ago.

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.

Overlap-Safe PPTX Dossier

Use this skill when a deck must be complete, polished, and layout-safe.

Non-Negotiable Layout Rules

  • Never cram dense content onto one slide. Split into more slides.
  • Track every intentional content rectangle: title, subtitle, panels, cards, diagrams, tables, images, and tree text.
  • Validate that every tracked rectangle stays within slide bounds.
  • Validate that tracked rectangles do not overlap unless the overlap is deliberate containment, such as text inside its own card.
  • Use TextFrame.fit_text() or conservative font sizes, but do not rely on auto-fit to rescue overloaded slides.
  • For file-tree appendix slides, chunk the tree into small fixed-size line groups; keep one monospaced text box per slide.
  • For tables, prefer monospaced text or pre-sized rows over huge PowerPoint tables.

Visual Style Guidance

When the user supplies a reference presentation:

  • Inspect the deck with python-pptx; if slides are image-only, extract media from ppt/media/ and use the images as style references or cover backgrounds.
  • Match the visual language rather than copying old content blindly.
  • For the Tlamatini reference style, prefer obsidian/dark stone backgrounds, copper and jade accents, thin ornamental lines, translucent cards, geometric diagrams, and light display typography.
  • Use icons as simple labeled glyphs, line shapes, or small cards when assets are not available.
  • Keep contrast high enough for extracted text and projected viewing.

Required Deck Content

The deck must include:

  • What the system is and what it does.
  • How the system works end to end.
  • How to use it from source, in chat, in Multi-Turn mode, and in the workflow designer.
  • Packaging/build path.
  • Agent catalog overview.
  • Repository facts and current HEAD.
  • Effective line counts by language, total effective lines, and methodology.
  • Largest files by effective lines.
  • Complete tracked file tree, split across appendix slides.
  • Latest changes or optimizations as a section, not as the whole deck.

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.
