deck-craft

A toolkit for building and reviewing slide decks in HTML, JSON, or PowerPoint-compatible form. It includes layout guidance, presentation structure rules, design handling, and automated checks in a browser.

In plain words
What is it for?
It is for creating fixed-stage HTML presentations, converting decks through JSON and PowerPoint, and assembling investor presentations from reusable layouts.
Why use it?
It helps keep a deck's argument, visual design, readability, and technical output consistent across different presentation formats.

Grade A, and why

deck-craft 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 yesterday.

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.

What it actually says

{
  "name": "deck-craft",
  "version": "1.16.0",
  "description": "Build, review or convert a slide deck across three targets from one body of craft: a self-contained fixed-stage HTML presentation, lecturn.deck/1 JSON with a .pptx round-trip, or an investor deck assembled from a bundled library of 200 slide layouts in 27 families and 21 recipes. Carries its own design layer rather than depending on a general design skill — a supplied DESIGN.md or token file is binding, a direction is authored on three named axes when no brand exists, and type is sized from a viewing-angle derivation rather than from web habit. Deck-specific narrative discipline: the title sequence written before any slide because the titles read in order are the argument, speaking-versus-reading density as an explicit fork, one idea per slide, and a named slide count treated as a contract. Ships a deterministic preflight gate that runs in a headless browser and is built to be unable to pass silently: the probe carries its own blocker and warning policy plus a stated consequence for every finding, refuses a config key it does not recognise, and echoes its configuration back so the runner can prove the settings that were asked for actually arrived. Only exit 0 is a pass — a probe that returned nothing, a config that never landed, a check that threw and a run that examined zero slides each get their own code and their own refusal. Regulated decks add per-slide disclosure checks sourced to SEC Regulation G and Item 10(e), the December 2022 Compliance and Disclosure Interpretations on equal-or-greater prominence, and ASIC RG 230; chart integrity covers truncated baselines, dual axes and inverted axes; and given the source document it cross-checks every figure on the deck against it, because fabrication arrives as texture around a real number rather than as an invented headline.",

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.
