## Reading Content

```bash
# Text extraction
python -m markitdown presentation.pptx
```

## Creating from Scratch — Workflow

**Use when no template or reference presentation is available.**

### Step 1: Research & Requirements

Search to understand user requirements — topic, audience, purpose, tone, content depth.

### Step 2: Select Color Palette & Fonts

Use the [Color Palette Reference](references/design-system.md#color-palette-reference) to select a palette matching the topic and audience. Use the [Font Reference](references/design-system.md#font-reference) to choose a font pairing.

### Step 3: Select Design Style

# Editing Existing Presentations

## Template-Based Workflow

When using an existing presentation as a template:

1. **Copy and analyze**:
```bash
cp /path/to/user-provided.pptx template.pptx
python -m markitdown template.pptx > template.md
```
Review `template.md` to see placeholder text and slide structure.

2. **Plan slide mapping**: For each content section, choose a template slide.

**USE VARIED LAYOUTS** — monotonous presentations are a common failure mode. Don't default to basic title + bullet slides. Actively seek out:
- Multi-column layouts (2-column, 3-column)
- Image + text combinations
- Full-bleed images with text overlay
- Quote or callout slides
- Section dividers
- Stat/number callouts
- Icon grids or icon + text rows

**Avoid:** Repeating the same text-heavy layout for every slide.

Match content type to layout style (e.g., key points -> bullet slide, team info -> multi-column, testimonials -> quote slide).

3. **Unpack**: Extract the PPTX into an editable XML tree using Python's `zipfile` module. Pretty-print the XML for readability.

4. **Build presentation** (do this yourself, not with subagents):
- Delete unwanted slides (remove from `<p:sldIdLst>`)
- Duplicate slides you want to reuse (copy slide XML, relationships, and update `Content_Types.xml` and `presentation.xml`)
- Reorder slides in `<p:sldIdLst>`
- **Complete all structural changes before step 5**

5. **Edit content**: Update text in each `slide{N}.xml`.
**Use subagents here if available** — slides are separate XML files, so subagents can edit in parallel.

6. **Clean**: Remove orphaned files — slides not in `<p:sldIdLst>`, unreferenced media, orphaned rels.

7. **Pack**: Repack the XML tree into a PPTX file. Validate, repair, condense XML, re-encode smart quotes.

Always write to `/tmp/` first, then copy to the final path. Python's `zipfile` module uses `seek` internally, which fails on some volume mounts (e.g. Docker bind mounts). Writing to a local temp path avoids this.

## Output Structure

Copy the user-provided file to `template.pptx` in cwd. This preserves the original and gives a predictable name for all downstream operations.

```bash
cp /path/to/user-provided.pptx template.pptx
```

```text
./
├── template.pptx # Copy of user-provided file (never modified)
├── template.md # markitdown extraction
├── unpacked/ # Editable XML tree
└── edited.pptx # Final repacked deck
```

Minimum expected deliverable: `edited.pptx`.

## Slide Operations

Slide order is in `ppt/presentation.xml` -> `<p:sldIdLst>`.

**Reorder**: Rearrange `<p:sldId>` elements.

**Delete**: Remove `<p:sldId>`, then clean orphaned files.

**Add**: Copy the source slide's XML file, its `.rels` file, and update `Content_Types.xml` and `presentation.xml`. Never manually copy slide files without updating all references — this causes broken notes references and missing relat

# QA Process & Common Pitfalls

## QA Process

**Assume there are problems. Your job is to find them.**

Your first render is almost never correct. Approach QA as a bug hunt, not a confirmation step. If you found zero issues on first inspection, you weren't looking hard enough.

### Content QA

```bash
python -m markitdown output.pptx
```

Check for missing content, typos, wrong order.

**Check for leftover placeholder text:**

```bash
python -m markitdown output.pptx | grep -iE "xxxx|lorem|ipsum|placeholder|this.*(page|slide).*layout"
```

If grep returns results, fix them before declaring success.

### Verification Loop

1. Generate slides -> Extract text with `python -m markitdown output.pptx` -> Review content
2. **List issues found** (if none found, look again more critically)
3. Fix issues
4. **Re-verify affected slides** — one fix often creates another problem
5. Repeat until a full pass reveals no new issues

**Do not declare success until you've completed at least one fix-and-verify cycle.**

### Per-Slide QA (for from-scratch creation)

```bash
python -m markitdown slide-XX-preview.pptx
```

Check for missing content, placeholder text, missing page number badge.

## Common Mistakes to Avoid

- **Don't repeat the same layout** — vary columns, cards, and callouts across slides
- **Don't center body text** — left-align paragraphs and lists; center only titles
- **Don't skimp on size contrast** — titles need 36pt+ to stand out from 14-16pt body
- **Don't default to blue** — pick colors that reflect the specific topic
- **Don't mix spacing randomly** — choose 0.3" or 0.5" gaps and use consistently
- **Don't style one slide and leave the rest plain** — commit fully or keep it simple throughout
- **Don't create text-only slides** — add images, icons, charts, or visual elements; avoid plain title + bullets
- **Don't forget text box padding** — when aligning lines or shapes with text edges, set `margin: 0` on the text box or offset the shape to account for padding
- **Don't use low-contrast elements** — icons AND text need strong contrast against the background
- **NEVER use accent lines under titles** — these are a hallmark of AI-generated slides; use whitespace or background color instead
- **NEVER use "#" with hex colors** — causes file corruption in PptxGenJS
- **NEVER encode opacity in hex strings** — use the `opacity` property instead
- **NEVER use async/await in createSlide()** — compile.js won't await
- **NEVER reuse option objects across PptxGenJS calls** — PptxGenJS mutates objects in-place

---

## Critical Pitfalls — PptxGenJS

### NEVER use async/await in createSlide()

```javascript
// WRONG - compile.js won't await
async function createSlide(pres, theme) { ... }

// CORRECT
function createSlide(pres, theme) { ... }
```

### NEVER use "#" with hex colors

```javascript
color: "FF0000"      // CORRECT
color: "#FF0000"     // CORRUPTS FILE
```

### NEVER encode opacity in hex strings

```javascript
shadow: { color: "00000020" }
