# presentation-maker

Build a complete, on-brand presentation from a single topic or outline file. The
skill is a **pipeline of small, single-purpose scripts** — one command per stage —
so each step is inspectable, debuggable, and composable.

> Russian triggers: `сделай презентацию`, `презентация`, `слайды`, `pptx`,
> `сделай доклад`, `собери слайды`, `структура слайдов`, `аутлайн презентации`,
> `16:9 слайды`, `презентация в powerpoint`.

Дека НЕ считается готовой, пока не пройдены все четыре gate: `verify_slides.py`
PASS, `fit_solver` PASS внутри build_html.py (смотри `.fit_report.json`),
`vision_qa.py finalize` PASS (реально просмотрено, не имитация), и `qa_pptx.py`
PASS для pptx-варианта. `content_profile.py` и `creative_brief.py` также можно
запускать отдельно (для отладки/просмотра решений) — `build_html.py` их не
требует как отдельный шаг, но выведет те же .profile.json/.brief.json сам.

Every stage reads/writes the same `deck.json` contract, so you can regenerate any
artifact after editing the spec.

## Stage commands


All commands run from the repo root. Scripts live in `scripts/`.

### 1. Strategy (optional but recommended)

```bash
python3 skills/presentation-maker/scripts/strategy.py --goal keynote
python3 skills/presentation-maker/scripts/strategy.py --audience "SaaS investors" --topic "Series A"
python3 skills/presentation-maker/scripts/strategy.py --list          # all presets
python3 skills/presentation-maker/scripts/strategy.py --show pitch    # one preset
```

Flags: `--goal` (`pitch|consulting|keynote|report|edu`), `--audience`, `--topic`,
`--language` (`ru|en`), `--list`, `--show <goal>`. If `goal` is omitted it is
inferred from `audience`/`topic` keywords, else defaults to `pitch`. The chosen
strategy (arc / mood / density / palette_name / layouts) is auto-applied by
`deck_md.py` when the matching frontmatter fields are absent.

### 2. Outline → spec

```bash
python3 skills/presentation-maker/scripts/deck_md.py outline.md -o deck.json
# overrides (take precedence over frontmatter):
python3 skills/presentation-maker/scripts/deck_md.py outline.md -o deck.json \
    --goal keynote --audience "investors" --lang ru --palette swift --tone confident
```

Flags: positional `md` (topic or outline file), `--out` (default `deck.json`),
`--goal`, `--audience`, `--tone`, `--palette` (theme name or mood), `--lang`/`--language`.
The outline format is documented in `references/strategy.md`; in short: a leading
YAML-ish frontmatter (`title`, `goal`, `audience`, `language`, `theme`, `density`,
`topic`) followed by slide blocks separated by a line containing only `---`, each
starting with `# Headline`.

### 3. HTML slides (16:9)

```bash
python3 skills/presentation-maker/scripts/build_html.py deck.json slides.html
```

Builds from the **modular base** (`templates/base.html` — tokens, typography,
components, navigation, all pattern/composition CSS included). Internally runs
`content_profile` → `creative_brief` → `composer` (constrained by both) →
`fit_solver` (geometry retry, up to 3 attempts per slide) before writing the
final HTML — see the Pipeline diagram above. Writes `slides.profile.json`,
`slides.brief.json`, `slides.fit_report.json` next to the output for
inspection. If any slide still fails fit after retries, the build succeeds
but prints the failing slide + reason to stderr — check `.fit_report.json`
before treating the deck as done. Output is a self-contained 16:9 deck.

### 4. Verification gate (MANDATORY)

```bash
python3 skills/presentation-maker/scripts/verify_slides.py slides.html --spec deck.json
```

Runs in real Chromium (Playwright) and checks, per slide: a heading + non-empty
content, no horizontal overflow, cards/rows hold their content (no clipping or
spill), text containers do not clip, and keyboard navigation switches slides.
**Exit 0 = pass; exit 1 = fail.**

### 4b. Visual QA gate (MANDATORY) — `vision_qa.py`

```bash
python3 skills/presentation-maker/scripts/vision_qa.py shoot slides.html --out-dir vision_shots
```

Screenshots every slide (via `.active` toggling, waiting out the CSS
transition) and prints the fixed 7-point rubric + the list of image paths.
**This script cannot judge the images itself** — only the agent running the
skill has vision. The agent MUST view each screenshot (image-reading tool,
not by re-reading the JSON) and score it against the printed rubric, then
record every verdict:

```bash
python3 skills/presentation-maker/scripts/vision_qa.py record slides.html \
    --slide 4 --verdict PASS --recommendation "..."   # one call per slide
python3 skills/presentation-maker/scripts/vision_qa.py finalize slides.html
```

`finalize` exits 0 only if every slide has a recorded verdict AND all are
PASS. A slide with no recorded verdict is FAIL ("не проверено"), never a
silent pass — there is no structural auto-pass fallback. Ни одна презентация
не считается готовой, пока не пройдены все четыре gate: `fit_solver` PASS
(Слой 3, внутри build_html.py — см. `.fit_report.json`), `verify_slides.py`
PASS, `vision_qa.py finalize` PASS (Слой 4, реально просмотрено агентом),
`qa_pptx.py` PASS (для pptx-варианта).

### 5. PowerPoint

```bash
python3 skills/presentation-maker/scripts/build_pptx.py deck.json deck.pptx

```

Draws a real `.pptx` via `python-pptx` on a 1600×900 design canvas (13.333×7.5",
16:9, `PX=7620` EMU/px): all 14 slide types rendered through the shared
**PPTX design system** — eyebrow, ghost page numbers, chrome (logo + page
indicator), decor ovals, tinted "sandwich" bookends, shadowed cards, numbered
step ovals, square bullet markers, oversized metrics/quote/hero numbers.
Fonts are **Arial** (never Inter — LibreOffice substitutes matter for QA).
See "PPTX design system" below for the full element set and contracts.

```bash
# geometric QA gate — run after every build (exit 0 = pass):
python3 skills/presentation-maker/scripts/qa_pptx.py deck.pptx --render
```

Checks per slide: shapes inside canvas, content above `BOTTOM_STOP`, no
text-overlap, tables fit; `--render` additionally exports JPEGs via
LibreOffice → `pdftoppm` for human/vision review. Design elements named
`ghost*`, `decor*`, `chrome-*` are exempt from bounds/content checks.

### 5b. Extern linter gate — `intern` (optional but recommended)

[`intern`](https://github.com/markusz/intern) (MIT) is an open-source CLI
linter for `.pptx`: alignment (`CLOSE_X/CLOSE_Y`), text quality
(`DOUBLE_SPACE`, `EMPTY_TEXTBOX`, `REPEATED_WORD`), margins, font/color
variety. It catches issues our geometric gate does not model — it already
found a real bug (triple spaces around `·` in the footer).

Install once (any of):

```bash
brew install markusz/intern/intern        # macOS
# or prebuilt binary: curl -L https://github.com/markusz/intern/releases/latest/download/intern-$(uname -m|sed s/x86_64/x86_64-apple-darwin/|sed s/arm64/aarch64-apple-darwin/).tar.gz | tar xz
```

Run through our wrapper (it whitelists design-system elements by shape name —
`ghost*`, `decor*`, `chrome-*`, `quote-*`, `process-card`, `step-num`,
`toc-*` — and can drop token rules for token-driven decks):

```bash
python3 skills/presentation-maker/scripts/qa_intern.py deck.pptx --skip-token-rules
# exit 0 = clean after design-filter; 1 = real violations; 2 = intern missing/error
```

`--skip-token-rules` ignores `FONT_SIZE_VARIETY`/`COLOR_VARIETY` — our design
system intentionally uses a token hierarchy (eyebrow 11pt … metrics 64pt,
quote mark 120pt). For non-token decks omit it to keep those checks.

### 6. PDF export

```bash
python3 skills/presentation-maker/scripts/build_pdf.py slides.html deck.pdf
# optional: python3 skills/presentation-maker/scripts/build_pdf.py slides.html deck.pdf --viewport 1600x900
```

Renders the **same themed `slides.html`** into a multi-page 16:9 PDF (one slide per
page) using Playwright — no separate layout/theme is re-implemented, so the PDF is
visually 1:1 with the HTML. See `references/pdf.md`.

### 7. Quality audit

```bash
python3 skills/presentation-maker/scripts/deck_audit.py deck.json --html slides.html
```

Deterministic, browser-free aesthetic gate (exit 0/1). Checks WCAG contrast,
no raw hex outside `:root`, ≤4 accent roles, assertion headlines, words-per-slide
budget, and a single mood across the deck. See `references/audit.md`.

    "layouts": ["big_number", "quote", "divider"]
  },
  "slides": [ /* slide objects, see below */ ]
}
```

### Slide object (content)

Each slide has a `type` (or `auto`/omitted → inferred from content) plus type-specific
fields. Common types and their key fields:

| type | key fields |
|---|---|
| `title` / `closing` | `title`, `subtitle?`, `presenter?`, `date?` |
| `divider` | `title`, `subtitle?` |
| `bullets` | `title`, `bullets[]` |
| `comparison` | `title`, `columns[]` → `{heading, points[]}` |
| `table` | `title`, `table` → `{headers[], rows[][], highlight_col?}` |
| `chart` | `title`, `chart` → `{categories[], series[]→{name,values[]}, note?}` |
| `process` | `title`, `steps[]` |
| `metrics` | `title`, `metrics[]` → `{value, label, icon?}` |
| `big_number` | `title?`, `value`, `label?`, `subtitle?`, `accent?` |
| `quote` | `title?`, `quote`, `attribution?` |
| `feature` | `title`, `features[]` → `{title, text?, icon?}` |
| `image_showcase` | `title`, `image`, `desc?`, `points?` |
| `timeline` | `title`, `items[]` → `{title, desc?}` |
| `kpi_row` | `title`, `kpis[]` / `metrics[]` |
| `logos` | `title`, `logos[]`, `note?` |
| `table_of_contents` | `title`, `items[]` → `{title, desc?}` |
| `centered_header` | `title`, `subtitle?`, `panel?` |

Valid `type` values: `title, divider, bullets, comparison, table, chart, process,
metrics, feature, big_number, quote, table_of_contents, timeline, image_showcase,
centered_header, kpi_row, logos, closing`.

## Theme + palette model

Themes are JSON files in `templates/themes/` (names: `general, modern, executive,
momentum, swift, standard, dynamic`). Each provides a `palette` (the `:root` CSS
variables above) and a `mood`. A `mood` is one of `swiss | editorial | flat | glass
| dark` and drives the aesthetic regime; `DEFAULT_THEMES` maps each mood to the
nearest theme file (`swiss→executive`, `editorial→standard`, `flat→modern`,
`glass→swift`, `dark→dynamic`). Icons for `metrics`/`feature` slides live in
`templates/icons/` as inline SVG (no emoji).

## Layout families

`build_html.py` and `build_pptx.py` share a `RENDERERS` map keyed by slide `type`.
When `type` is `auto`/missing, `pick_layout()` infers the best fit from content
keys (quote → `quote`, columns → `comparison`, steps → `process`, metrics →
`metrics`, numeric table → `chart`, text table → `table`, features → `feature`,
logos → `logos`, etc.), avoiding repeating the previous slide's type when plausible.

## Generative composition layer (v4.0)

Every slide's composition is **synthesized from scratch** — not picked from a
template list. `scripts/composer.py` derives a deterministic parameter set from
a deck **seed** (title + date + slide index):

- title position (left / center / vertical / bottom-left) and scale;
- content grid (1-3 columns), layout (cards / columns / plain / split);
- one accent mode per slide (word / underline / icons) + intensity level;
- decor motif (none / ovals / dots / grid / beams), card radius and shadow.

So the same deck rebuilt on another day gets a **different composition mix**
(deterministic and reproducible via the seed). The pattern files in
`templates/patterns/*.json` remain as reference recipes (ideas for the
parameter space), not as a fixed menu. `verify_slides.py`, `deck_audit.py`,
`qa_pptx.py`, `qa_intern.py` gates run unchanged.

## Accent embedding (two brand colors, no mixing)

Decks may carry **two brand accents** (e.g. teal primary + rose accent). They are
never blended in one element, and text on an accent-colored block is always
`on-primary` (white). The accent is woven into individual slides via modes
(`build_html.py` → `pick_accent_mode()`, spread across the deck, never repeated
on adjacent slides):

- **`accent-word`** — first word of the title entirely in the accent color
  (never a lone letter floating away from its word);
- **`accent-underline`** — accent hairline under the title;
- **`accent-icons`** — metric icons + values in the accent color (light cards only).

Set the two accents in the theme: `primary` (structure: headings, lines,
markers, gradients, duotones) and `accent` (accent points only). Graphs stay in
the primary family so gradients/duotones never mix the two brands.

## Typography floor (card text)

Body text inside cards must stay readable at 16:9 projection — floor 17px,
labels ≥ 17px, metric values 30–48px, timeline descriptions ≥ 15px. Headings
scale via `--t-*` tokens. `verify_slides.py` re-checks overflow after any
font-size change.

## Anti-template design rules

Summarized from `references/design-system.md` (full rules there). Enforced
mechanically by `deck_audit.py`:

- **≤ 2 typefaces**, **≤ 4 accent roles** (primary + graph colors); keep 60-30-10.
- **One idea per slide**; content < 60% of slide area; generous whitespace.
- **Assertion headlines** — full sentences with a verb (a conclusion, not a topic).
- **WCAG contrast** ≥ 4.5:1 for text, ≥ 3:1 for large/non-text (graph lines, borders).
- **Zero raw hex outside `:root`** — every color is a CSS token.
- **One `mood` per deck**; one radius/stroke language; no emoji icons (SVG only).
- **Words-per-slide budget**: 60 (standard) / 120 (text-heavy); concise ≈ 20.

## PPTX design system (build_pptx.py)

`build_pptx.py` renders every slide on a **1600×900 design canvas**
(13.333×7.5", `PX = 7620` EMU/px). Fixed contracts:

| Constant | Value | Meaning |
|---|---|---|
| `MARGIN_X` | 96 px | horizontal page margin |
| `TITLE_Y` / `TITLE_H` | 56 / 96 px | title band (autofits ≤ 2 lines) |
| `CONTENT_Y` | 180 px | all content starts below the title band |
| `BOTTOM_STOP` | 80 px | nothing may end lower than `H - 80` |
| Font | **Arial** everywhere | LibreOffice-safe; never Inter in PPTX |

### Full element set

| # | Element | Where | Spec |
|---|---|---|---|
| 1 | **eyebrow** | title, divider, toc, quote, closing, content | 12 pt bold, tracking 3.6, `accent_soft` on dark / `primary` on light; y≈88 |
| 2 | **ghost-num** | every slide | huge translucent page number; name `ghost-num` — **exempt from QA bounds** |
| 3 | **chrome** | every slide | logo 30×30 (`chrome-logo`) + `NN / NN` page indicator (`chrome-page`) — exempt |
| 4 | **decor-ovals** | title, divider, closing | translucent ovals (alpha 15–22%) in `graph_1`; name `decor` — exempt |
| 5 | **tinted sandwich** | title / divider / closing | dark `primary` background, light text; content slides use `background` |
| 6 | **cards** | bullets, comparison, metrics, process, timeline, feature, toc | rounded rect + shadow (blur 10 / dist 3 / alpha 9%), stroke `p.stroke` |
| 7 | **step-num / toc-num** | process, timeline, toc | numbered OVAL 36–44 px, `NN`/`01` labels |
| 8 | **square bullet markers** | bullets (`style="cards"`) | `bullet-marker` squares in accent color |
| 9 | **hairline** | comparison | 2 px divider line under column heading |
| 10 | **metric value** | metrics | 64 pt bold (min 30), color cycles `graph_0..7` |
| 11 | **hero number** | big_number | 110 pt bold (min 40) + 30 pt label + 18 pt subtitle |
| 12 | **opening quote** | quote | 120 pt bold `"` (min 80), quote 34 pt, attribution 20 pt muted |
| 13 | **arrow →** | process | 22 pt `→` between step cards |

### Rules

- **eyebrow is mandatory** on title / divider / closing; optional elsewhere.
- ghost/decor/chrome are decorative: `qa_pptx.py` skips names starting
  `ghost*`, `decor*`, `chrome-*` for bounds/content checks, but they must stay
  visually inside the canvas — verify on `--render` JPEGs.
- All 14 types share the same palette tokens and the same visual language
  (cards, ovals, eyebrow) — a deck must read as one system, not 14 templates.
- The same `deck.json` drives HTML and PPTX: keep both builds green
  (`verify_slides.py` + `qa_pptx.py`) before shipping.

## Dependencies

- `python3` (stdlib only for `deck_md.py`, `strategy.py`, `deck_audit.py`, `qa_bento.py`).
- `python-pptx` for `build_pptx.py`: `pip install python-pptx`.
- `playwright` for `verify_slides.py` and `build_pdf.py`:
  `pip install playwright && playwright install chromium`.
