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.

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 | $0.00110 | $0.06628 |
| Opus 5 | $0.00055 | $0.03314 |
| Sonnet 5 | $0.00022 | $0.01326 |
| Haiku 4.5 | $0.00011 | $0.00663 |
Grade A, and why
pptx-official scanned grade A with 1 finding 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 3d 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.

PPTX Skill
An Apache-2.0 toolkit for producing, editing, and reading Microsoft PowerPoint
(.pptx) files. Written from scratch against the public
ECMA-376 / ISO/IEC 29500 (PresentationML)
specification and built on permissively-licensed tooling (python-pptx MIT,
pptxgenjs MIT, lxml BSD-3-Clause, Pillow MIT-CMU, optional external
binaries soffice MPL 2.0 and pdftoppm GPL) so it can be reused in
commercial projects without restriction.
Pipeline
Phase 0 Read the source and the workspace
Phase 1 Confirm two things ← theme and imagery, unless delegated
Phase 2 Outline with action titles ← ghost deck test; approval when it matters
Phase 3 Prepare assets
Phase 4 Build
Phase 5 Verify and repair ← loop until acceptance passes
Phase 6 Hand off
Phase 0 — Read. Read the source, and look for a template, an earlier deck, or brand assets in the workspace. A template answers Phase 1 on its own.
Phase 1 — Confirm two things. Theme, and whether the deck carries
photographs. Everything else — slide count (around 10, never fewer than 8),
16:9, language, fonts, file name — is a default you take and state. Ask both
in one ask_user call. Ask nothing at all when the user delegated the whole
job, when the run is non-interactive, or when a template already decides it.
interview.md has the defaults, the delegation rule, and how
to phrase the two questions.
Decide the mode rather than asking it. Argument-first for papers, studies, results, board and policy material: argument, then data, then layout, then aesthetics, on a light ground with one accent and no decorative imagery. Visual-first for launches, keynotes, and brand work. When both fit, choose argument-first.
Phase 2 — Outline, then the ghost deck test. One line per slide: its action title — a full sentence stating that slide's takeaway, not a topic label — plus its evidence and visual form. Then read only the action titles in order. They must tell the complete argument alone; if they do not, fix the outline, because no visual work will rescue it.

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-official is a skill published in the GitHub repository evoelsewhere/evoflux (7 stars, last pushed today), licensed Apache-2.0. It adds 110 tokens to every session and 6,628 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-06.
