Content Editing System\n\n## How It Works\n\nWhen a user says \"change the executive summary,\" the system:\n\n1. **AI identifies the target**: Determines if user wants entire text box or single element\n2. **AI generates markdown**: Creates clean bullet points like `• First point\\n• Second point`\n3. **System parses markdown**: Identifies bullets, sub-bullets, plain text\n4. **System generates XML**: Converts to proper PowerPoint structure with bullet formatting\n5. **System replaces content**: Swaps entire text box content while preserving structure\n\n## AI Decision Logic\n\n```\nUser: \"Change the executive summary\"\n→ AI: Text box replacement (entire content section)\n→ Response: textBoxId: \"TB1\", slideNumber: 2\n\nUser: \"Change the executive summary title\" \n→ AI: Single element replacement\n→ Response: elementId: \"2A\"\n\nUser: \"Use this template to make a deck about tortoises\"\n→ AI: Template detected (placeholder content like \"Front cover template\")\n→ Response: action: \"multi-slide\" (replace all template content)\n```\n\n## Template Recognition\n\nThe AI automatically detects template files by looking for placeholder content:\n- \"Front cover template\"\n- \"Test description\" \n- \"Executive Summary\" with generic content\n- Other template-like placeholder text\n\nWhen templates are detected, the AI defaults to **multi-slide operations** that replace all placeholder content with coordinated, themed content. This matches user intent - templates are meant to be completely transformed, not just have content added.\n\n## Markdown Format\n\nAI generates content in simple markdown:\n```\n• Main bullet point\n• Another main point\n • Sub-bullet (indented)\n• Final main point\n```\n\n## XML Generation\n\nSystem converts markdown to PowerPoint XML by generating only the inner content:\n```xml\n\n\n \n\n\n\n \n \n \n Main bullet point\n\n```\n\nThe system then replaces the content between existing `` tags to avoid XML structure corruption.\n\n## Text Box vs Element Targeting\n\n**Text Box Replacement** (entire content):\n- User says: \"change executive summary\", \"replace all bullets\"\n- AI returns: `textBoxId` + `slideNumber`\n- System replaces: Entire `` content\n\n**Element Replacement** (single item):\n- User says: \"change title\", \"replace first bullet\" \n- AI returns: `elementId`\n- System replaces: Single `` tag\n\n## Current Limitations\n\n- Only handles body text boxes (bullets) for full replacement\n- Sub-bullet indentation is simplified\n- No support for complex formatting (bold, italic, etc.)\n- Text box identification relies on placeholder type matching\n\n## Troubleshooting\n\n**Content duplication**: Check if AI returned `elementIds` array instead of `textBoxId`\n**Missing bullets**: Verify markdown parsing found bullet markers (`•`, `-`, `*`)\n**Wrong text box**: Check if text box regex pattern matches the slide structure\n**XML corruption**: Ensure generated content doesn't include `` wrapper tags\n**PowerPoint repair needed**: Usually indicates nested XML tags or missing required attributes",[],[329],{"_103":338,"_95":339,"_154":340,"_156":-5,"_157":137,"_158":341,"_160":161,"_105":342,"_100":32,"_163":252,"_165":343,"_166":22,"_167":-5,"_168":344,"_98":345},"7239c0a0-c34c-11f0-b7c8-42dde27851f2","README-development.md","7239c172-c34c-11f0-b7c8-42dde27851f2",327,["D",1763339354975],"# Development Roadmap\n\n## Next Major Feature: Slide Structural Operations\n\n### Current Limitation\nThe system can only edit content within existing slides. It cannot:\n- Duplicate slides\n- Delete slides \n- Reorder slides\n- Create new slides from templates\n\n### Implementation Plan: Slide Duplication & Deletion\n\n#### Phase 1: PPTX Structure Understanding\n**Goal**: Map out all the files and relationships that need updating\n\n**Key Files in PPTX**:\n```\n├── [Content_Types].xml # Declares all file types\n├── _rels/.rels # Root relationships\n├── ppt/\n│ ├── presentation.xml # Slide order and references\n│ ├── _rels/presentation.xml.rels # Slide file relationships\n│ └── slides/\n│ ├── slide1.xml # Individual slide content\n│ ├── slide2.xml\n│ └── slide3.xml\n```\n\n**Research Tasks**:\n1. Document exact XML structure for slide references in `presentation.xml`\n2. Map relationship IDs in `presentation.xml.rels`\n3. Understand slide numbering and ID assignment patterns\n4. Test what happens when files are missing/extra\n\n#### Phase 2: Safe Slide Duplication\n**Goal**: Copy existing slide with all proper relationships\n\n**Implementation Strategy**:\n```typescript\ninterface SlideOperation {\n type: 'duplicate' | 'delete' | 'reorder';\n sourceSlide?: number; // For duplication\n targetSlide?: number; // For deletion \n insertAfter?: number; // Where to place duplicated slide\n modifications?: { // Content changes to make after duplication\n textBoxId: string;\n content: string;\n };\n}\n```\n\n**Steps for Slide Duplication**:\n1. **Copy slide XML file**: `slide2.xml` → `slide4.xml`\n2. **Update presentation.xml**: Add new `` entry with unique ID\n3. **Update presentation.xml.rels**: Add relationship to new slide file\n4. **Update [Content_Types].xml**: Add entry for new slide file\n5. **Renumber subsequent slides**: If inserting in middle, update file names\n6. **Apply content modifications**: Use existing text box replacement logic\n\n**Error Handling**:\n- Validate all relationship IDs are unique\n- Ensure slide numbering is sequential\n- Verify all referenced files exist\n- Test with PowerPoint to ensure no corruption\n\n#### Phase 3: Safe Slide Deletion\n**Goal**: Remove slide and clean up all references\n\n**Steps for Slide Deletion**:\n1. **Remove slide XML file**: Delete `slide3.xml`\n2. **Update presentation.xml**: Remove corresponding `` entry\n3. **Update presentation.xml.rels**: Remove relationship entry\n4. **Update [Content_Types].xml**: Remove slide file entry\n5. **Renumber remaining slides**: `slide4.xml` → `slide3.xml`, etc.\n6. **Update all relationship references**: Fix any broken IDs\n\n#### Phase 4: Enhanced AI Integration\n**Goal**: AI can plan and execute structural changes\n\n**Enhanced Command Structure**:\n```json\n{\n \"action\": \"structural-multi-slide\",\n \"operations\": [\n {\n \"type\": \"duplicate\",\n \"sourceSlide\": 2,\n \"insertAfter\": 2,\n \"modifications\": {\n \"textBoxId\": \"TB0\",\n \"content\": \"Advanced Tortoise Care\"\n }\n },\n {\n \"type\": \"edit\", \n \"slideNumber\": 3,\n \"textBoxId\": \"TB1\",\n \"content\": \"• Advanced feeding tips\\n• Habitat optimization\"\n },\n {\n \"type\": \"delete\",\n \"slideNumber\": 5\n }\n ]\n}\n```\n\n**AI Prompt Enhancement**:\n- Recognize when user needs more slides than available\n- Suggest slide duplication with content variations\n- Plan slide deletion when content is redundant\n- Coordinate structural changes with content changes\n\n### Risk Mitigation\n\n#### High-Risk Areas\n1. **Relationship ID conflicts**: Duplicate IDs break PowerPoint\n2. **File numbering gaps**: Missing slide3.xml with slide4.xml present\n3. **Orphaned references**: presentation.xml referencing deleted slides\n4. **XML namespace issues**: Malformed relationship XML\n\n#### Testing Strategy\n1. **Unit tests**: Test each XML modification function\n2. **Integration tests**: Full PPTX generation and PowerPoint validation\n3. **Edge cases**: Empty slides, complex layouts, embedded media\n4. **Rollback capability**: Ability to revert to original file on failure\n\n#### Implementation Phases\n- **Phase 1**: Research and documentation (1-2 sessions)\n- **Phase 2**: Slide duplication only (2-3 sessions) \n- **Phase 3**: Slide deletion (1-2 sessions)\n- **Phase 4**: AI integration (1 session)\n\n### Success Criteria\n- [ ] Can duplicate any slide without corruption\n- [ ] Can delete any slide without breaking references\n- [ ] PowerPoint opens files without repair prompts\n- [ ] AI can plan multi-slide operations with structural changes\n- [ ] Comprehensive error handling and rollback capability\n\n### Notes\n- Start with duplication (safer than deletion)\n- Test extensively with Mini_template_01.pptx\n- Keep detailed logs of all XML modifications\n- Consider creating backup before structural operations",[],[339],{"_103":347,"_95":348,"_154":349,"_156":-5,"_157":137,"_158":350,"_160":161,"_105":351,"_100":333,"_163":252,"_165":352,"_166":22,"_167":-5,"_168":353,"_98":354},"3565625a-c31b-11f0-a71a-42dde27851f2","README-how_pptx-works.md","14158e04-c31b-11f0-8d02-42dde27851f2",270,["D",1763318207577],"# PPTX Open XML Cheat Sheet for Editing Agents\n\nThis document explains how a `.pptx` file works internally so you can parse and edit PowerPoint presentations via XML: change text, swap images, tweak layouts, and safely add or remove slides.\n\n---\n\n## 1. What a PPTX File Actually Is\n\nA `.pptx` file is a ZIP archive following the Open Packaging Convention (OPC) and the Office Open XML (OOXML) PresentationML standard.\n\nInside the ZIP you’ll find:\n\n- XML “parts” (content)\n- Binary assets (images, media, embedded files)\n- Relationship files (`*.rels`)\n- A content-type manifest (`[Content_Types].xml`)\n\nYou must:\n\n1. Treat the PPTX as a ZIP. \n2. Use the relationships to navigate, not just filenames. \n3. Preserve content types and relationship integrity when editing.\n\n---\n\n## 2. High-Level Directory Layout\n\nTypical PPTX structure (paths are inside the ZIP):\n\n- `/_rels/.rels` \n - Root relationships (e.g., to `ppt/presentation.xml`).\n- `/[Content_Types].xml` \n - Declares MIME types for each part type.\n- `/ppt/presentation.xml` \n - Main presentation part (list of slide references, masters, etc.).\n- `/ppt/_rels/presentation.xml.rels` \n - Relationships from the presentation to slide parts, slide masters, theme, etc.\n- `/ppt/slides/slide1.xml`, `slide2.xml`, ... \n - Individual slide parts.\n- `/ppt/slides/_rels/slide1.xml.rels`, ... \n - Relationships from slides to layouts, images, charts, etc.\n- `/ppt/slideMasters/slideMaster1.xml`, ... \n - Slide master parts.\n- `/ppt/slideLayouts/slideLayout1.xml`, ... \n - Slide layout parts.\n- `/ppt/notesSlides/notesSlide1.xml`, ... \n - Notes for slides.\n- `/ppt/theme/theme1.xml`, ... \n - Theme (colors, fonts).\n- `/ppt/media/image1.png`, `image2.jpeg`, ... \n - Images and other media.\n\nOther optional parts: charts, embedded objects, custom XML, etc.\n\n---\n\n## 3. Core OPC Concepts: Parts & Relationships\n\n### 3.1 Parts\n\nA part is a file inside the package, such as:\n\n- `ppt/slides/slide3.xml` (XML) \n- `ppt/media/image5.png` (PNG)\n\nEach part has:\n\n- A path inside the ZIP \n- A content type (from `[Content_Types].xml`) \n- Zero or more relationships to other parts or external URIs \n\n### 3.2 Relationships (`*.rels`)\n\nRelationships are stored in `.rels` XML files next to their “source” part.\n\nEach `` has:\n\n- `Id` – local identifier like `rId1` \n- `Type` – URI describing the relationship type \n- `Target` – relative path to target part \n- `TargetMode` – `Internal` (default) or `External`\n\nImportant:\n\n- `rId` values are only unique within their source part.\n- You must resolve targets via the appropriate `.rels` file, not by guessing filenames.\n\n---\n\n## 4. Presentation Structure: How Slides Are Wired\n\nThe entry point is `ppt/presentation.xml`.\n\n### 4.1 Main Presentation XML\n\n`ppt/presentation.xml` root is typically ``.\n\nKey elements:\n\n- `` – ordered list of slide instances \n - Child `` elements:\n - `id`: unique numeric ID within this list\n - `r:id`: references a relationship in `presentation.xml.rels`\n- `` – slide masters \n- `` – notes master \n- `` – handout master \n- `` – slide size \n- `` – default text styles \n\nSlide order is determined by the order of `` elements in ``, not by the numeric suffix in `slideN.xml`.\n\n### 4.2 How to Find All Slides\n\nAlgorithm:\n\n1. Open `ppt/presentation.xml`. \n2. Read all `` elements in `` in order. \n3. For each ``, get its `r:id`. \n4. In `ppt/_rels/presentation.xml.rels`, find the `` with `Id=\"\"`. \n5. Its `Target` is a slide part path, e.g. `slides/slide3.xml`.\n\nUse this relationship-based mapping instead of assuming `slideN.xml` is slide number N.\n\n---\n\n## 5. Slide XML (PresentationML Basics)\n\nA slide part (e.g. `ppt/slides/slide1.xml`) typically looks like:\n\n~~~xml\n\n \n \n \n \n \n ...\n\n~~~\n\nInside `` you’ll see:\n\n- `` – shapes (rectangles, text boxes, titles, etc.) \n- `` – images \n- `` – group shapes \n- `` – connectors \n- `` – charts, tables, SmartArt, etc.\n\nA typical `` (shape) has:\n\n- `` – non-visual properties (ID, name, placeholder info) \n- `` – shape properties (geometry, line, fill, transform) \n- `` – text content (if the shape holds text)\n\n---\n\n## 6. Text Model: Finding and Editing Text\n\nText is stored using DrawingML (`a:` namespace) inside ``.\n\n### 6.1 Text Body Structure\n\nTypical text-bearing shape:\n\n~~~xml\n\n ...\n ...\n \n \n \n \n ... \n \n \n Some text \n \n \n \n \n More text\n \n \n ... \n \n\n~~~\n\nElements:\n\n- `` – paragraph \n- `` – paragraph properties (bullets, level, alignment) \n- `` – run (a sequence of uniformly formatted text) \n- `` – run properties (size, font, color, bold, etc.) \n- `` – literal text \n- `` – manual line break \n- `` – field (date, slide number, etc.), also containing ``\n\n### 6.2 Practical Rules for Text Editing\n\n- To collect text from a slide:\n - Traverse `p:sld → p:cSld → p:spTree → p:sp` with a `p:txBody`.\n - For each `a:p`:\n - Concatenate all `a:t` text nodes in order.\n - Insert line breaks when encountering `a:br/`.\n- For search/replace:\n - Operate at the `a:t` level where possible.\n - Preserve the structure of `a:r` and `a:rPr` to keep formatting.\n - Handle text that may be split across multiple runs, even mid-word.\n- Placeholders (title, body, footer, etc.) are identified by `` in the shape’s non-visual properties, not by the text itself.\n\n---\n\n## 7. Layouts, Masters, and Placeholders\n\n### 7.1 Slide Masters and Layouts\n\nHierarchy:\n\n- Presentation → Slide Masters (`/ppt/slideMasters/slideMasterN.xml`) \n- Each Slide Master → Slide Layouts (`/ppt/slideLayouts/slideLayoutN.xml`) via relationships and `` \n- Each Slide → a Slide Layout via its slide `.rels` file\n\nSlide master/layout parts look similar to slides:\n\n- `` / `` root \n- `/` – shapes and placeholders \n- `` – default text styles \n- References to theme (`/ppt/theme/themeN.xml`)\n\nSlides inherit positioning and styles from their layout and master.\n\n### 7.2 Placeholders (``)\n\nPlaceholders designate semantic roles:\n\n~~~xml\n\n \n \n \n \n \n \n \n ...\n\n~~~\n\nCommon `type` values:\n\n- `title`, `ctrTitle` – title, centered title \n- `subTitle` – subtitle \n- `body` – main content \n- `pic` – picture placeholder \n- `dt` – date \n- `sldNum` – slide number \n- `ftr` – footer \n\nSlides override placeholder text by providing shapes with matching placeholder metadata (`type`, `idx`).\n\n### 7.3 Changing Layout of a Slide\n\nConceptually:\n\n1. In the slide’s `.rels` file, change the relationship of type `slideLayout` to target a different `slideLayoutX.xml`. \n2. Ensure the new layout’s placeholders are compatible (same logical roles), or be prepared to reposition or re-create shapes.\n\n---\n\n## 8. Images, Graphics, and Other Media\n\n### 8.1 Images (`` and ``)\n\nTypical picture shape:\n\n~~~xml\n\n ...\n \n \n ...\n \n ... \n\n~~~\n\n- `r:embed=\"rId5\"` refers to a relationship in `ppt/slides/_rels/slideX.xml.rels`. \n- That relationship’s `Target` is something like `../media/image3.png`. \n- The actual image is at `ppt/media/image3.png`.\n\nTo swap an image while preserving position and size:\n\n1. Find the `` with `r:embed=\"rIdX\"`. \n2. Resolve `rIdX` in the slide’s `.rels` file. \n3. Overwrite the binary file at the `Target` path with the new image bytes (preferably same format). \n4. Do not change XML unless pointing to a new media part.\n\n### 8.2 Shapes and Coordinates\n\nShapes use EMUs (English Metric Units):\n\n- 1 inch = 914400 EMUs \n- 1 cm ≈ 360000 EMUs \n\nPositions and sizes are defined in ``:\n\n~~~xml\n\n \n \n\n~~~\n\nAdjust these attributes to move/resize shapes.\n\n### 8.3 Charts, Tables, SmartArt\n\nThese reside in `` with `` inside. Charts often reference:\n\n- `/ppt/charts/chartN.xml` \n- Possibly embedded Excel parts under `/xl/`\n\nFor a generic editing agent:\n\n- Avoid restructuring chart/table XML unless you fully know the schema. \n- For simple text edits (titles, labels), locate `` text nodes within chart/table parts using similar traversal.\n\n---\n\n## 9. Themes, Colors, and Fonts\n\nThemes live under `/ppt/theme/themeN.xml`.\n\nThey define:\n\n- Color schemes \n- Font schemes \n- Effects and other defaults \n\nSlide masters reference themes, and slides/masts can override color mapping using `` and ``.\n\nFor text-only edits, you normally do not need to touch theme parts. Just keep them intact.\n\n---\n\n## 10. `[Content_Types].xml`: Do Not Break It\n\n`/[Content_Types].xml` declares MIME types for parts.\n\nExamples:\n\n~~~xml\n\n \n \n \n \n \n\n~~~\n\nRules:\n\n- When adding a new slide `slideN.xml`, if an `` for `/ppt/slides/slideN.xml` or a generic slide override is already present, you typically don’t need to change anything. \n- When introducing a totally new extension (e.g., `.foo`), add a `` or `` entry. \n- Do not remove or corrupt existing entries.\n\nBreaking this file can make the PPTX unreadable.\n\n---\n\n## 11. Common Editing Tasks: Recommended Algorithms\n\n### 11.1 Get All Text in All Slides\n\n1. From `ppt/presentation.xml`, list all `` in order. \n2. For each `r:id`, resolve to `slides/slideX.xml` via `presentation.xml.rels`. \n3. For each slide:\n - Parse `ppt/slides/slideX.xml`. \n - Traverse `p:cSld → p:spTree → p:sp`. \n - For each `p:sp` that has `p:txBody`:\n - For each `a:p`:\n - Collect `a:t` values, respecting `a:br/` as line breaks.\n\nOptional: use `` info to categorize text (title, body, footer, etc.).\n\n### 11.2 Replace Text with New Text (Within a Shape)\n\nScenario: Replace entire text of a title or content placeholder.\n\nSimplest robust approach:\n\n1. Identify the target shape by placeholder (`p:ph type=\"title\"`, `body`, etc.) or by existing text. \n2. Inside its `p:txBody`, remove existing `a:p` children. \n3. Insert new structure:\n\n~~~xml\n\n \n \n New text here\n \n\n~~~\n\nFor multiple paragraphs, add multiple `a:p` elements.\n\nFormatting-preserving approach:\n\n- Keep `a:pPr` and `a:rPr` nodes. \n- Only modify the content of `a:t`, preserving run structure.\n\n### 11.3 Replace an Image\n\n1. Identify which `p:pic` to edit (by placeholder type `pic`, by name, or by its current image). \n2. Find `` inside its `p:blipFill`. \n3. In `ppt/slides/_rels/slideX.xml.rels`, find `Relationship Id=\"rIdX\"`. \n4. Resolve its `Target`, e.g., `../media/image5.png` → `ppt/media/image5.png`. \n5. Overwrite that file with your new image bytes (matching format, e.g., PNG → PNG). \n\nNo changes needed in XML or `[Content_Types].xml` if you reuse the same part.\n\n### 11.4 Add a New Slide Based on an Existing Layout\n\n1. Choose a layout:\n - From slide masters and their ``, or \n - From an existing slide’s `slideLayout` relationship.\n\n2. Create a new slide part:\n - Option 1: clone an existing slide and clear the content you want to reset. \n - Option 2: construct a minimal valid `p:sld` referencing the chosen layout.\n\n3. Save it as `ppt/slides/slideN.xml` (unique filename).\n\n4. In `ppt/_rels/presentation.xml.rels`, add a relationship:\n\n~~~xml\n\n~~~\n\n5. In `ppt/presentation.xml`, add a new `` under ``:\n\n~~~xml\n\n~~~\n\n- `id` must be a unique integer within ``.\n\n6. In `ppt/slides/_rels/slideN.xml.rels`, add a `slideLayout` relationship:\n\n~~~xml\n\n~~~\n\n7. Ensure `[Content_Types].xml` has an appropriate `` for slide parts (usually already present).\n\n### 11.5 Reorder Slides\n\n1. In `ppt/presentation.xml`, locate ``. \n2. Reorder the `` elements themselves. \n\nDon’t change their `id` or `r:id`; slide order is determined solely by element order.\n\n---\n\n## 12. Robustness Guidelines for an Editing Agent\n\nTo make safe, reliable changes:\n\n1. Always use relationships:\n - Never infer master/layout/media links purely from filenames or numeric IDs.\n\n2. Preserve unknown XML:\n - If you don’t need to modify it, copy elements and attributes through unchanged.\n\n3. Preserve namespaces:\n - Keep existing `xmlns:p`, `xmlns:a`, `xmlns:r` declarations and prefixes as-is.\n\n4. Make minimal edits:\n - Focus on local text/shape/media changes instead of global restructures.\n\n5. Keep `[Content_Types].xml` consistent:\n - Only add entries when introducing new part types or extensions.\n - Avoid changing or removing existing entries.\n\n6. Maintain well-formed XML:\n - Ensure all tags are properly closed and nesting is valid.\n\n---\n\n## 13. Minimal Parsing Strategy Summary\n\nFor most real-world editing tasks, the following subset is sufficient:\n\n- Understand the ZIP and locate:\n - `ppt/presentation.xml`\n - `ppt/_rels/presentation.xml.rels`\n - `ppt/slides/slide*.xml` and their `.rels`\n - `ppt/media/*`\n\n- Use:\n - `` + `presentation.xml.rels` to enumerate slides in order.\n - `p:cSld → p:spTree → p:sp → p:txBody → a:p → a:r → a:t` to read/write text.\n - `p:pic` + `a:blip r:embed=\"...\"` + slide `.rels` to handle images.\n - `p:ph` metadata to recognize placeholders (title, body, footer, etc.).\n - `a:xfrm` (`a:off`, `a:ext`) for shape coordinates (optional for text-only edits).\n\nStaying within this structure lets you:\n\n- Extract and modify text (titles, bullet lists, body text). \n- Replace images without disturbing layouts. \n- Add, remove, and reorder slides. \n- Respect existing themes, masters, and layouts without needing to deeply modify them.",[],[348],{"_103":356,"_95":357,"_154":358,"_156":-5,"_157":137,"_158":359,"_160":161,"_105":360,"_100":361,"_163":252,"_165":362,"_166":22,"_167":-5,"_168":363,"_98":364},"80f5e182-c34c-11f0-a254-42dde27851f2","README.md","019a84ad-a102-73ff-a194-7c1b3c0d93d0",329,["D",1763339379692],37,"# PPTX XML Editing Bot - Content-Aware AI System\n\n## 🎯 **CURRENT STATUS: Content-Aware AI Editing Restored! 🎉**\n\nThe sophisticated content-aware AI system has been fully restored after fixing syntax errors.\n\n### **✅ Current Features**\n- **Multi-Slide Content-Aware AI**: AI sees ALL slides and their text elements with context\n- **Multi-Slide Operations**: AI can edit multiple slides in one request (\"make whole deck about cats\")\n- **Text Box Relationship Understanding**: AI knows which elements belong to the same text box\n- **Smart Slide Targeting**: AI automatically finds the right slide based on content\n- **Text Box Replacement**: AI can replace entire text boxes (all bullets) or individual elements\n- **Markdown to PowerPoint XML**: AI generates clean markdown, system converts to proper XML\n- **Precise Element Selection**: AI chooses the right text element using slide-aware IDs (1A, 2B, 3C, etc.)\n- **Natural Language Commands**: \"Change the executive summary to something about cats\"\n- **Surgical XML Editing**: Makes precise edits to specific elements without corruption\n- **File Upload/Download**: Drag & drop PPTX processing\n- **Thread-Based Chat**: Multiple conversation threads with persistent history\n\n### **🔧 Recently Fixed**\n- **Syntax Errors**: Resolved all missing braces and orphaned code blocks\n- **Content-Aware System**: Fully restored the sophisticated AI processing\n- **Element Mapping**: Restored precise element targeting and surgical edits\n\n### **Example Commands That Work**\n```\n\"Change the main heading on the first slide to 5 words about tortoises\"\n\"Replace the title with something about giraffes\"\n\"Update the large text to say hello world\"\n\"Add some lorem ipsum to the slide\"\n```\n\n## 🚀 **MILESTONE ACHIEVED: Content-Aware AI Editing**\n\n### **How It Works**\n1. **Content Extraction**: System reads slide XML and extracts all text elements with context\n2. **AI Analysis**: OpenAI sees actual slide content: `[A] \"Kwaku Slide One\" (18pt, top-center)`\n3. **Smart Selection**: AI chooses the right element based on user's natural language\n4. **Precise Edit**: System makes surgical XML changes to exactly the right element\n\n### **Technical Architecture**\n\n#### **Content-Aware AI Flow**\n```typescript\ninterface SlideText {\n text: string; // \"Welcome to Company\"\n fontSize: number; // 44\n position: {...}; // top-center\n elementId: string; // \"A\"\n xmlPath: string; // For precise editing\n}\n```\n\n#### **AI Decision Making**\n```\nPPTX Content:\n\nSlide 1 text elements:\nText Box TB0 (title):\n [1A] \"Welcome to Company\" (44pt, top-center)\nText Box TB1 (body):\n [1B] \"Quarterly Review\" (18pt, middle-left)\n\nSlide 2 text elements:\nText Box TB0 (title):\n [2A] \"Executive Summary\" (36pt, top-center)\nText Box TB1 (body):\n [2B] \"Key findings and recommendations\" (16pt, middle-left)\n [2C] \"First bullet point\" (16pt, middle-left)\n [2D] \"Second bullet point\" (16pt, middle-left)\n\nUser: \"Change the executive summary content to 3 bullet points about cats\"\nAI Decision: \"User wants to replace entire body content under Executive Summary\"\nAI Response: {\n \"textBoxId\": \"TB1\", \n \"slideNumber\": 2,\n \"content\": \"• Cats are independent animals\\n• Cats love to sleep in sunny spots\\n• Cats communicate through purring\"\n}\nSystem: Parses markdown → Generates proper PowerPoint XML → Replaces entire text box\n```\n\n#### **PPTX XML Processing**\nThe system uses deep knowledge of PPTX structure to make precise edits. See [`README-how_pptx-works.md`](./README-how_pptx-works.md) for complete technical details on:\n- PPTX ZIP structure and relationships\n- XML parsing and text extraction\n- Safe editing patterns that preserve file integrity\n\n## 🏗️ **Important: Structure of Slide Elements**\n\nUnderstanding how PowerPoint organizes content is crucial for the AI system to make intelligent editing decisions.\n\n### **Text Boxes vs. Text Elements**\n- **Text Box** = `` element (PowerPoint shape container)\n- **Text Elements** = `` tags within the text box (individual text runs)\n- **One text box can contain multiple paragraphs** (``) with multiple text runs (``)\n\n### **How Bullets Are Actually Structured**\n```xml\n\n\n\n\n Executive Summary\n\n\n\n\n First bullet point\n Second bullet point\n Third bullet point\n\n```\n\n### **Why Element-by-Element Parsing Is Safer**\n- **Preserves XML Structure**: Each `` replacement maintains bullet formatting\n- **Avoids Corruption**: No need to reconstruct complex XML with indentation, bullet chars, etc.\n- **Granular Control**: Can replace individual bullets or groups of bullets\n- **User Flexibility**: \"Change first bullet\" vs \"change all executive summary content\"\n\n### **PowerPoint Placeholder Types**\n- `` - Main slide titles\n- `` - Content areas (usually containing bullets)\n- `` - Centered titles\n- `` - Subtitles\n\n### **AI Strategy: Text Box Awareness Without Grouping**\nThe AI sees individual elements but understands their relationships:\n```\nText Box 1 (title): [2A] \"Executive Summary\"\nText Box 2 (body): [2B] \"First bullet\" [2C] \"Second bullet\" [2D] \"Third bullet\"\n```\n\nWhen user says \"change executive summary content\" → AI targets the entire text box\nWhen user says \"change executive summary title\" → AI targets element 2A\n\n### **Content Generation: Markdown to PowerPoint XML**\nThe system uses a clean separation between content generation and technical implementation:\n\n1. **AI generates markdown-like content**:\n ```\n • First bullet point about cats\n • Second bullet point about dogs \n • Third bullet point about birds\n ```\n\n2. **System parses and converts to PowerPoint XML**:\n ```xml\n \n First bullet point about cats\n Second bullet point about dogs\n Third bullet point about birds\n \n ```\n\n**Benefits:**\n- ✅ **AI focuses on content**: No need to understand PowerPoint XML complexity\n- ✅ **System handles formatting**: Proper bullet structure, indentation, XML escaping\n- ✅ **Clean separation**: Content generation vs. technical implementation\n- ✅ **Flexible**: Supports bullets, sub-bullets, plain text, mixed content\n\n### **Success Criteria Met ✅**\n- [x] AI sees actual slide content (not blind heuristics)\n- [x] Smart element selection based on context\n- [x] Natural language commands work reliably\n- [x] Precise XML editing without file corruption\n- [x] Clean, maintainable codebase under 500 lines per file\n\n## 🏗️ **Clean Project

`POST /api/chat` - Send message (with content-aware AI)\n- `POST /api/upload` - Upload PPTX file\n- `GET /api/download/:fileId` - Download processed file\n\n## 🔧 **Development Guidelines**\n\n### **Code Organization**\n- **File Size Limit**: Keep files under **500 lines** for maintainability\n- **Single Responsibility**: Each file has one clear purpose\n- **No Legacy Cruft**: Remove broken code instead of keeping \"fallbacks\"\n- **Content-Aware First**: AI should see actual content, not use blind heuristics\n\n### **Documentation Requirements**\n- **Keep README Updated**: When you make code changes, update this README to reflect the current state\n- **Technical Reference**: See [`README-how_pptx-works.md`](./README-how_pptx-works.md) for detailed PPTX XML structure documentation\n- **Document Milestones**: Update status sections when major features are completed\n- **Remove Outdated Content**: Delete old implementation details that no longer apply\n\n### **Key Principles**\n1. **Intelligence Over Heuristics**: Let AI see content and make smart decisions\n2. **Precise Over Broad**: Make surgical edits to specific elements\n3. **Clean Over Complex**: Remove unnecessary complexity and legacy code\n4. **Working Over Perfect**: Focus on functionality that actually works\n5. **Document Over Assume**: Keep documentation current with implementation\n\n## 📚 **Additional
