# Manual Testing Guide: Markdown Rendering Feature
|
||||
|
||||
**Feature**: 003-render-ai-analyis - Render AI Analysis as Formatted HTML
|
||||
**Tasks**: T020 (Security Verification) and T021 (Performance Validation)
|
||||
|
||||
---
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before you begin, ensure:
|
||||
- ✅ Virtual environment is activated
|
||||
- ✅ Dependencies are installed (`pip install -r requirements.txt`)
|
||||
- ✅ You have the test data generator script: `prepare_markdown_manually.py`
|
||||
|
||||
---
|
||||
|
||||
## Step 1: Create Test Data
|
||||
|
||||
Run the test data generator to create 4 different feedback samples:
|
||||
|
||||
```bash
|
||||
python prepare_markdown_manually.py
|
||||
```
|
||||
|
||||
This creates:
|
||||
1. **Rich Formatting Test** - Headings, lists, tables, code blocks, links
|
||||
2. **XSS Security Test** - Script tags, iframes, javascript: protocol
|
||||
3. **Complex Tables Test** - Nested lists, multiple tables, code samples
|
||||
4. **Performance Test** - 30 sections with tables, lists, and code
|
||||
|
||||
The script will output the feedback IDs created.
|
||||
|
||||

|
||||
|
||||
## Step 2: Start the Flask Application
|
||||
|
||||
### Option A: Using run.py (Recommended)
|
||||
|
||||
```bash
|
||||
python run.py
|
||||
```
|
||||
|
||||
### Option B: Using Flask CLI
|
||||
|
||||
```bash
|
||||
export FLASK_APP=app
|
||||
export FLASK_ENV=development
|
||||
flask run
|
||||
```
|
||||
|
||||
The application will start on **http://localhost:5000**
|
||||
|
||||

||||
- Any content from "evil.com"
|
||||
|
||||
2. **Check Link Security**:
|
||||
```
|
||||
F12 → Elements → Find any <a> tag in analysis section
|
||||
```
|
||||
|
||||
**Every link should have:**
|
||||
- `target="_blank"`
|
||||
- `rel="noopener noreferrer nofollow"`
|
||||
|
||||
3. **Test XSS Protection**:
|
||||
- View page source (Ctrl+U)
|
||||
- Search for "alert("
|
||||
- **Should find**: 0 results in analysis section
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Issue: Markdown not rendering (shows raw markdown)
|
||||
|
||||
**Check**:
|
||||
1. Filter is registered in `app/__init__.py` line 186
|
||||
2. Template uses `{{ feedback.analysis|markdown(feedback.feedback_id) }}`
|
||||
3. No Python errors in console
|
||||
|
||||
### Issue: Page returns 404
|
||||
|
||||
**Check**:
|
||||
1. Feedback ID is correct
|
||||
2. Product is "test-product"
|
||||
3. You're logged in as admin user
|
||||
|
||||
### Issue: Performance test fails
|
||||
|
||||
**Possible causes**:
|
||||
1. Running in debug mode (adds overhead)
|
||||
2. Browser extensions slowing down page
|
||||
3. System under heavy load
|
||||
|
||||
**Solution**: Run in production mode or disable extensions

# Implementation Plan: Render AI Analysis as Formatted HTML
|
||||
|
||||
**Branch**: `003-render-ai-analyis` | **Date**: 2025-10-17 | **Spec**: [spec.md](./spec.md)
|
||||
|
||||
## Summary
|
||||
|
||||
Convert markdown-formatted AI analysis to HTML for display on feedback detail pages. Use **markdown2** library for conversion with HTML sanitization via **bleach** to prevent XSS attacks. Implement as a Jinja2 template filter for seamless integration with existing Flask templates.
|
||||
|
||||
## Technical Context
|
||||
|
||||
**Language/Version**: Python 3.11+
|
||||
**Primary Dependencies**: Flask 3.0+, markdown2 (markdown conversion), bleach (HTML sanitization)
|
||||
**Storage**: File-based (existing - no changes needed)
|
||||
**Testing**: pytest, pytest-flask
|
||||
**Target Platform**: Linux server (existing Flask app)
|
||||
**Project Type**: Web application (app/ directory structure)
|
||||
**Performance Goals**: < 2 seconds page load for feedback detail (per SC-005)
|
||||
**Constraints**: < 200ms markdown conversion time, whitelist-based HTML sanitization
|
||||
**Scale/Scope**: Low - single template filter, no API changes
|
||||
|
||||
## Constitution Check
|
||||
|
||||
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
|
||||
|
||||
### ✅ Specification-First Development
|
||||
- **Status**: PASS
|
||||
- **Evidence**: Complete specification exists at `specs/003-render-ai-analyis/spec.md` with 9 acceptance scenarios, 9 functional requirements, and 5 success criteria
|
||||
|
||||
### ✅ Test-First Discipline
|
||||
- **Status**: PASS (planned)
|
||||
- **Evidence**: Test-first workflow will be followed during implementation phase
|
||||
- **Test Plan**: Unit tests for markdown conversion, contract tests for template rendering, integration tests for full page display
|
||||
|
||||
### ✅ Independent User Stories
|
||||
- **Status**: PASS
|
||||
- **Evidence**: Single P1 user story ("View Formatted AI Analysis") is independently testable and delivers value without dependencies
|
||||
|
||||
### ✅ Simplicity & Justification
|
||||
- **Status**: PASS
|
||||
- **Evidence**: Using well-established libraries (markdown2 + bleach) instead of custom parser. No new architectural layers introduced.
|
||||
- **Approach**: Simple Jinja2 template filter - minimal code change to existing template
|
||||
|
||||
### ✅ Documentation as Code
|
||||
- **Status**: PASS
|
||||
- **Evidence**: Specification, clarifications, and this implementation plan are version-controlled in `/specs/003-render-ai-analyis/`
|
||||
|
||||
**Gate Result**: ✅ PASS - No constitution violations. Proceed to Phase 0.

```
|
||||
|
||||
**Structure Decision**: Using existing web application structure (app/ directory). Markdown conversion implemented as a utility module with Jinja2 filter registration. No architectural changes required - this is a pure display-layer enhancement.

|
||||
|
||||
## Phase 0: Research & Technology Selection
|
||||
|
||||
### Decision: Markdown Library Selection
|
||||
|
||||
**Chosen**: **markdown2** v2.4+
|
||||
|
||||
**Rationale**:
|
||||
- Well-established library (15+ years, widely used)
|
||||
- Native support for tables (via "tables" extra)
|
||||
- Good performance for typical AI analysis content (< 50ms for 5KB markdown)
|
||||
- Simple API: `markdown2.markdown(text, extras=['tables', 'fenced-code-blocks'])`
|
||||
- Actively maintained with security updates
|
||||
|
||||
**Alternatives Considered**:
|
||||
1. **python-markdown**: More complex API, requires separate extension management
|
||||
2. **mistune**: Faster but less mature table support, more complex configuration
|
||||
3. **CommonMark-py**: Strict CommonMark compliance, but no table support without extensions
|
||||
|
||||
**Rejected Because**: markdown2 offers the best balance of simplicity (per user requirement), feature completeness (tables + code blocks), and proven stability.
|
||||
|
||||
### Decision: HTML Sanitization Approach
|
||||
|
||||
**Chosen**: **bleach** v6.1+
|
||||
|
||||
**Rationale**:
|
||||
- Industry-standard HTML sanitization library
|
||||
- Whitelist-based tag/attribute filtering (matches FR-003 requirement)
|
||||
- Can add `rel="noopener noreferrer nofollow"` to all links (FR-004)
|
||||
- Built-in defense against XSS attacks
|
||||
- Simple configuration: `bleach.clean(html, tags=ALLOWED_TAGS, attributes=ALLOWED_ATTRS)`
|
||||
|
||||
**Alternatives Considered**:
|
||||
1. **html5lib + custom filtering**: More control but requires more code
|
||||
2. **nh3 (Rust-based)**: Faster but adds Rust dependency complexity
|
||||
3. **Manual regex filtering**: Unsafe and error-prone
|
||||
|
||||
**Rejected Because**: bleach is the Python standard for HTML sanitization, widely vetted, and matches our whitelist requirement exactly.
|
||||
|
||||
### Decision: Integration Approach
|
||||
|
||||
**Chosen**: Jinja2 template filter (`{{ feedback.analysis|markdown }}`)
|
||||
|
||||
**Rationale**:
|
||||
- Minimal code change - only template modification needed
|
||||
- Consistent with Flask/Jinja2 patterns already in use
|
||||
- Automatic escaping safety (Jinja2 marks filter output as safe)
|
||||
- No API or routing changes required
|
||||
- Easy to test in isolation
|
||||
|
||||
**Alternatives Considered**:
|
||||
1. **Pre-process in route handler**: Would require changing dashboard routes
|
||||
2. **Model property**: Would tie display logic to data model
|
||||
3. **JavaScript client-side rendering**: Violates "no JavaScript libraries" constraint
|
||||
|
||||
**Rejected Because**: Template filter is the simplest, most idiomatic Flask approach with zero architectural impact.
|
||||
|
||||
### Best Practices Research
|
||||
|
||||
**Markdown Conversion**:
|
||||
- Use `extras=['tables', 'fenced-code-blocks', 'code-friendly']` for comprehensive formatting
|
||||
- Set `safe_mode=False` (we'll sanitize with bleach afterward, not markdown2's unsafe mode)
|
||||
- Handle empty/None input gracefully
|
||||
|
||||
**HTML Sanitization Configuration**:
|
||||
```python
|
||||
ALLOWED_TAGS = ['h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'p', 'br',
|
||||
'strong', 'em', 'code', 'pre',
|
||||
'ul', 'ol', 'li',
|
||||
'table', 'thead', 'tbody', 'tr', 'th', 'td',
|
||||
'a']
|
||||
|
||||
ALLOWED_ATTRIBUTES = {
|
||||
'a': ['href', 'title', 'target', 'rel'],
|
||||
'code': ['class'], # For syntax highlighting hints
|
||||
'*': [] # No attributes on other tags
|
||||
}
|
||||
```
|
||||
|
||||
**Link Security**:
|
||||
- Use bleach's `Cleaner` with link callback to enforce `target="_blank"` and `rel="noopener noreferrer nofollow"`
|
||||
|
||||
**Error Handling**:
|
||||
- Wrap conversion in try/except
|
||||
- On exception, return `f"<pre>{escape(original_markdown)}</pre>"` (per FR-006)
|
||||
- Log warning with feedback_id (per FR-009)
|
||||
|
||||
**Performance**:
|
||||
- markdown2 benchmarks: ~10ms for 1KB, ~50ms for 10KB
|
||||
- bleach benchmarks: ~5ms for typical output
|
||||
- Total: well under 200ms constraint
|
||||

|
||||
|
||||
## Phase 1: Data Model & Contracts
|
||||
|
||||
### Data Model
|
||||
|
||||
*File: `specs/003-render-ai-analyis/data-model.md`*
|
||||
|
||||
**No new entities or data changes required**. This feature is purely presentational - it transforms existing `Feedback.analysis` (string) at display time.
|
||||
|
||||
**Existing Entity (unchanged)**:
|
||||
- **Feedback.analysis**: `str | None` - Contains markdown-formatted text generated by Claude AI
|
||||
|
||||
**Transformation Flow**:
|
||||
```
|
||||
Feedback.analysis (markdown string)
|
||||
↓
|
||||
markdown_filter(text)
|
||||
↓
|
||||
markdown2.markdown(text, extras=[...])
|
||||
↓
|
||||
bleach.clean(html, tags=ALLOWED, ...)
|
||||
↓
|
||||
Jinja2 safe HTML output
|
||||
```
|
||||
|
||||
### API Contracts
|
||||
|
||||
*File: `specs/003-render-ai-analyis/contracts/template-filter.md`*
|
||||
|
||||
#### Contract: `markdown` Jinja2 Filter
|
||||
|
||||
**Signature**: `markdown(value: str | None, feedback_id: str = "unknown") -> Markup`
|
||||
|
||||
**Input**:
|
||||
- `value`: Markdown-formatted string (or None)
|
||||
- `feedback_id`: Optional feedback ID for logging
|
||||
|
||||
**Output**: Flask `Markup` object (HTML-safe string)
|
||||
|
||||
**Behavior**:
|
||||
|
||||
| Input | Output | Logging |
|
||||
|-------|--------|---------|
|
||||
| Valid markdown | Sanitized HTML | None |
|
||||
| Malformed markdown | Best-effort HTML | Warning with feedback_id |
|
||||
| Conversion exception | `<pre>{escaped_original}</pre>` | Warning with feedback_id |
|
||||
| None or empty string | Empty string | None |
|
||||
| Contains `<script>` | Sanitized (script removed) | Warning with feedback_id |
|
||||
| Contains image `` | Image tag removed | None |
|
||||
|
||||
**Examples**:
|
||||
|
||||
```python
|
||||
# Headings
|
||||
markdown("## Summary")
|
||||
→ "<h2>Summary</h2>"
|
||||
|
||||
# Lists
|
||||
markdown("- Item 1\n- Item 2")
|
||||
→ "<ul><li>Item 1</li><li>Item 2</li></ul>"
|
||||
|
||||
# Links (with security attributes added)
|
||||
markdown("[Link](http://example.com)")
|
||||
→ '<a href="http://example.com" target="_blank" rel="noopener noreferrer nofollow">Link</a>'
|
||||
|
||||
# Tables
|
||||
markdown("| A | B |\n|---|---|\n| 1 | 2 |")
|
||||
→ "<table><thead><tr><th>A</th><th>B</th></tr></thead><tbody><tr><td>1</td><td>2</td></tr></tbody></table>"
|
||||
|
||||
# XSS attempt (sanitized)
|
||||
markdown("<script>alert('xss')</script>")
|
||||
→ "" (empty - script stripped)
|
||||
|
||||
# Fallback on exception
|
||||
markdown("{{invalid}}") # Causes markdown2 exception
|
||||
→ "<pre>{{invalid}}</pre>"
|
||||
```
|
||||
|
||||
**Contract Tests** (`tests/contract/test_markdown_filter.py`):
|
||||
- Test each markdown element type (headings, lists, bold, italic, code, links, tables)
|
||||
- Test security: script injection, iframe injection, event handlers
|
||||
- Test fallback: malformed markdown, conversion exceptions
|
||||
- Test edge cases: None, empty string, very long input
|
||||
|
||||
### Template Changes
|
||||
|
||||
*File: `app/templates/dashboard/detail.html`*
|
||||
|
||||
**Before** (line 105):
|
||||
```jinja2
|
||||
{{ feedback.analysis|safe }}
|
||||
```
|
||||
|
||||
**After**:
|
||||
```jinja2
|
||||
{{ feedback.analysis|markdown(feedback.feedback_id) }}
|
||||
```
|
||||
|
||||
**Rationale**: The `markdown` filter handles both conversion and sanitization, returning pre-escaped `Markup`. No need for `|safe` - filter output is already marked safe.
|
||||
|
||||
### Quickstart Guide
|
||||
|
||||
*File: `specs/003-render-ai-analyis/quickstart.md`*
|
||||
|
||||
#### For Developers: Adding Markdown Rendering
|
||||
|
||||
**1. Install dependencies**:
|
||||
```bash
|
||||
pip install markdown2==2.4.12 bleach==6.1.0
|
||||
```
|
||||
|
||||
**2. Register the filter** (already done in `app/__init__.py`):
|
||||
```python
|
||||
from app.utils.markdown_utils import markdown_filter
|
||||
|
||||
def create_app(config_name='development'):
|
||||
app = Flask(__name__)
|
||||
# ... existing setup ...
|
||||
|
||||
# Register markdown filter
|
||||
app.jinja_env.filters['markdown'] = markdown_filter
|
||||
|
||||
return app
|
||||
```
|
||||
|
||||
**3. Use in templates**:
|
||||
```jinja2
|
||||
{{ some_markdown_content|markdown }}
|
||||
|
||||
{# With feedback ID for logging #}
|
||||
{{ feedback.analysis|markdown(feedback.feedback_id) }}
|
||||
```
|
||||
|
||||
**4. Configuration** (optional, in `app/utils/markdown_utils.py`):
|
||||
```python
|
||||
# Customize allowed tags
|
||||
ALLOWED_TAGS = ['h1', 'h2', ...] # Modify as needed
|
||||
|
||||
# Customize markdown extras
|
||||
MARKDOWN_EXTRAS = ['tables', 'fenced-code-blocks']
|
||||
```
|
||||
|
||||
#### For Testers: Verifying Markdown Rendering
|
||||
|
||||
**Manual Test**:
|
||||
1. Navigate to feedback detail page with AI analysis
|
||||
2. Verify headings are styled (not `##`)
|
||||
3. Verify lists have bullets/numbers
|
||||
4. Verify links are clickable and open in new tab
|
||||
5. Verify tables are formatted with rows/columns
|
||||
6. Verify code has monospace font
|
||||
|
||||
**Automated Test**:
|
||||
```bash
|
||||
pytest tests/contract/test_markdown_filter.py -v
|
||||
pytest tests/integration/test_markdown_rendering.py -v
|
||||
```
|
||||
|
||||
#### Security Verification
|
||||
|
||||
**Test XSS Prevention**:
|
||||
1. Create feedback with analysis containing: `<script>alert('xss')</script>`
|
||||
2. View feedback detail page
|
||||
3. **Expected**: No script execution, content is stripped
|
||||
4. Check browser console for errors (should be none)
|
||||
|
||||
**Test Link Security**:
|
||||
1. Inspect any link in rendered analysis
|
||||
2. **Expected attributes**: `target="_blank" rel="noopener noreferrer nofollow"`

- Easy to use interface
|
||||
- Great performance improvements
|
||||
- Excellent customer support
|

2. Add more customization options
|
||||
3. Fix known bugs in the dashboard
|
||||
4. Enhance mobile responsiveness
|
||||
|
||||
### Technical Details
|
||||
|
||||
The system uses `Flask` framework with the following code structure:
|
||||
|
||||
```python
|
||||
@app.route('/dashboard')
|
||||
def dashboard():
|
||||
return render_template('dashboard.html')
|
||||
```
|
||||
|
||||
This provides a clean separation of concerns.

### JavaScript Protocol
|
||||
|

# Feature Specification: Render AI Analysis as Formatted HTML
|
||||
|
||||
**Feature Branch**: `003-render-ai-analyis`
|
||||
**Created**: 2025-10-17
|
||||
**Status**: Draft
|
||||
**Input**: User description: "Render ai analyis as html. When I view a feedback detail, the ai analysis is shown as plain text markdown without any formating. This is not very usefull and the analysis markdown shoud be rendered as html and integrated in the feedback detail as formated html."
|
||||
|
||||
## User Scenarios & Testing *(mandatory)*
|
||||
|
||||
### User Story 1 - View Formatted AI Analysis (Priority: P1)
|
||||
|
||||
Product owners viewing feedback details see AI analysis rendered as formatted HTML with proper headings, lists, emphasis, and structure instead of plain markdown text. This makes the analysis easier to read and understand, improving the ability to quickly extract insights from customer feedback.
|
||||
|
||||
**Why this priority**: This is the core value of the feature. The AI analysis is only useful if it's readable and well-formatted. Currently, users see raw markdown which defeats the purpose of having AI-generated insights.
|
||||
|
||||
**Independent Test**: Can be fully tested by navigating to any feedback detail page that has AI analysis and verifying that markdown elements (headings, bold, lists, etc.) are properly rendered as HTML formatting.
|
||||
|
||||
**Acceptance Scenarios**:
|
||||
|
||||
1. **Given** a feedback item has AI analysis with markdown headings (e.g., `## Summary`, `### Key Points`), **When** the product owner views the feedback detail page, **Then** the headings are displayed as properly sized and styled HTML headings
|
||||
2. **Given** a feedback item has AI analysis with bullet lists or numbered lists, **When** the product owner views the feedback detail page, **Then** the lists are rendered as proper HTML lists with indentation and bullets/numbers
|
||||
3. **Given** a feedback item has AI analysis with bold text (`**important**`) or italic text (`*emphasis*`), **When** the product owner views the feedback detail page, **Then** the text appears with proper bold/italic formatting
|
||||
4. **Given** a feedback item has AI analysis with code blocks or inline code, **When** the product owner views the feedback detail page, **Then** the code is displayed in a monospace font with appropriate background styling
|
||||
5. **Given** a feedback item has AI analysis with markdown links (e.g., `[text](url)`), **When** the product owner views the feedback detail page, **Then** the links are rendered as clickable HTML anchor tags that open in a new tab with security attributes (rel="noopener noreferrer nofollow")
|
||||
6. **Given** a feedback item has AI analysis with markdown tables, **When** the product owner views the feedback detail page, **Then** the tables are rendered as properly formatted HTML tables with rows and columns
|
||||
7. **Given** a feedback item has AI analysis containing images or embedded content, **When** the product owner views the feedback detail page, **Then** these elements are excluded from the rendered output
|
||||
8. **Given** a feedback item has AI analysis containing potentially dangerous HTML (scripts, iframes, event handlers), **When** the product owner views the feedback detail page, **Then** only whitelisted safe formatting tags are rendered and all dangerous content is removed
|
||||
9. **Given** a feedback item has no AI analysis yet, **When** the product owner views the feedback detail page, **Then** the AI analysis section is not displayed (existing behavior preserved)
|
||||

|
||||
|
||||
## Clarifications
|
||||
|
||||
### Session 2025-10-17
|
||||
|
||||
- Q: When markdown-to-HTML conversion fails (e.g., library error, unexpected exception), how should the system behave? → A: Fall back to displaying the raw markdown text surrounded with a preformatted HTML tag to preserve line breaks
|
||||
- Q: What level of sanitization should be applied to the converted HTML? → A: Whitelist-based: allow only safe formatting tags (headings, lists, bold, italic, code, paragraphs, links)
|
||||
- Q: Should the system support additional markdown features beyond basic formatting? → A: Include links and tables, but exclude images and embedded content
|
||||
- Q: How should external links behave for security and user experience? → A: External links open in new tab with rel="noopener noreferrer nofollow" for security
|
||||
- Q: Should conversion issues be logged for monitoring and debugging? → A: Log warnings for conversion issues with feedback ID for debugging
|
||||
|
||||
---
|
||||
|
||||
### Edge Cases
|
||||
|
||||
- When the AI analysis contains malformed markdown (e.g., unclosed tags, invalid syntax), the system renders it as best-effort HTML and logs a warning with the feedback ID
|
||||
- When markdown-to-HTML conversion completely fails (e.g., library exception), the system falls back to displaying the raw markdown in a preformatted block and logs a warning with the feedback ID
|
||||
- When the AI analysis contains HTML-like characters (e.g., `<`, `>`, `&`), they are escaped before markdown processing
|
||||
- When the AI analysis is empty or contains only whitespace, the AI Analysis section is not displayed
|
||||
- When the AI analysis is extremely long with many nested lists or headings, the system still renders within the 2-second page load budget
|
||||
- When the AI analysis contains potentially unsafe content (e.g., JavaScript, embedded scripts), it is removed by HTML sanitization and a warning is logged with the feedback ID
|
||||
|
||||
## Requirements *(mandatory)*
|
||||
|
||||
### Functional Requirements
|
||||
|
||||
- **FR-001**: System MUST convert markdown-formatted AI analysis to HTML before displaying it on feedback detail pages
|
||||
- **FR-002**: System MUST support standard markdown elements including headings (h1-h6), bold, italic, lists (ordered and unordered), code blocks, inline code, links, and tables; images and embedded content are explicitly excluded
|
||||
- **FR-003**: System MUST sanitize the converted HTML using a whitelist approach, allowing only safe formatting tags (headings, lists, bold, italic, code, paragraphs, links, tables) and removing all potentially dangerous content (scripts, iframes, event handlers, images, embedded content, etc.)
|
||||
- **FR-004**: System MUST configure all links to open in a new tab with `target="_blank"` and include security attributes `rel="noopener noreferrer nofollow"` to prevent window access and search engine link transfer
|
||||
- **FR-005**: System MUST preserve the existing behavior when no AI analysis is present (do not display the analysis section)
|
||||
- **FR-006**: System MUST handle malformed markdown gracefully without causing page rendering errors; when conversion completely fails, fall back to displaying raw markdown in a preformatted HTML block
|
||||
- **FR-007**: System MUST apply appropriate styling to the rendered HTML to ensure readability and visual consistency with the rest of the interface
|
||||
- **FR-008**: System MUST escape HTML-like characters in the original markdown to prevent unintended HTML injection
|
||||
- **FR-009**: System MUST log warnings when markdown conversion encounters issues (malformed syntax, sanitization removes content, conversion failures), including the feedback ID for debugging purposes
|
||||
|
||||
### Key Entities
|
||||
|
||||
- **AI Analysis**: Text content containing markdown-formatted analysis generated by Claude AI. Stored as plain text with markdown syntax, needs to be converted to HTML for display.
|
||||
|
||||
## Success Criteria *(mandatory)*
|
||||
|
||||
### Measurable Outcomes
|
||||
|
||||
- **SC-001**: Product owners can read and understand AI analysis 50% faster due to improved formatting and visual hierarchy
|
||||
- **SC-002**: 100% of supported markdown elements (headings, lists, bold, italic, code, links, tables) are properly rendered as HTML
|
||||
- **SC-003**: Zero XSS vulnerabilities introduced by the HTML rendering functionality
|
||||
- **SC-004**: Users can distinguish between different sections of AI analysis (summary, sentiment, key points) at a glance due to proper heading hierarchy
|
||||
- **SC-005**: Page load time for feedback detail remains under 2 seconds even with complex AI analysis content

# Tasks: Render AI Analysis as Formatted HTML
|
||||
|
||||
**Branch**: `003-render-ai-analyis`
|
||||
**Input**: Design documents from `/specs/003-render-ai-analyis/`
|
||||
**Prerequisites**: plan.md, spec.md
|
||||
|
||||
**Organization**: Tasks organized by user story to enable independent implementation and testing.
|
||||
|
||||
## Format: `[ID] [P?] [Story] Description`
|
||||
- **[P]**: Can run in parallel (different files, no dependencies)
|
||||
- **[Story]**: Which user story this task belongs to (e.g., US1)
|
||||
- Include exact file paths in descriptions
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Setup (Shared Infrastructure)
|
||||
|
||||
**Purpose**: Add markdown rendering dependencies to existing project
|
||||
|
||||
- [X] T001 Add markdown2==2.4.12 and bleach==6.1.0 to requirements.txt
|
||||
- [X] T002 Install dependencies with pip install -r requirements.txt
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Foundational (Blocking Prerequisites)
|
||||
|
||||
**Purpose**: No foundational tasks required - this is a pure presentation layer enhancement
|
||||
|
||||
**⚠️ Note**: This feature has no blocking prerequisites. User story implementation can begin immediately after setup.
|
||||
|
||||
**Checkpoint**: Dependencies installed - user story implementation can now begin
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: User Story 1 - View Formatted AI Analysis (Priority: P1) 🎯 MVP
|
||||
|
||||
**Goal**: Product owners see AI analysis rendered as formatted HTML with headings, lists, tables, links, and proper security (XSS prevention, safe link attributes)
|
||||
|
||||
**Independent Test**: Navigate to any feedback detail page with AI analysis and verify markdown elements (headings, bold, lists, tables, links) are properly rendered as HTML formatting with security attributes
|
||||
|
||||
### Tests for User Story 1 (Test-First Discipline)
|
||||
|
||||
**⚠️ CRITICAL**: Write these tests FIRST, ensure they FAIL before implementation begins
|
||||
|
||||
- [X] T003 [P] [US1] Unit test for markdown conversion with None/empty input in tests/unit/test_markdown_utils.py
|
||||
- [X] T004 [P] [US1] Unit test for markdown headings conversion in tests/unit/test_markdown_utils.py
|
||||
- [X] T005 [P] [US1] Unit test for markdown lists conversion in tests/unit/test_markdown_utils.py
|
||||
- [X] T006 [P] [US1] Unit test for markdown bold/italic conversion in tests/unit/test_markdown_utils.py
|
||||
- [X] T007 [P] [US1] Unit test for markdown code blocks conversion in tests/unit/test_markdown_utils.py
|
||||
- [X] T008 [P] [US1] Unit test for markdown tables conversion in tests/unit/test_markdown_utils.py
|
||||
- [X] T009 [P] [US1] Unit test for markdown links with security attributes in tests/unit/test_markdown_utils.py
|
||||
- [X] T010 [P] [US1] Unit test for XSS prevention (script/iframe injection) in tests/unit/test_markdown_utils.py
|
||||
- [X] T011 [P] [US1] Unit test for image/embedded content exclusion in tests/unit/test_markdown_utils.py
|
||||
- [X] T012 [P] [US1] Unit test for fallback to preformatted block on exception in tests/unit/test_markdown_utils.py
|
||||
- [X] T013 [P] [US1] Unit test for warning logs on conversion issues in tests/unit/test_markdown_utils.py
|
||||
- [X] T014 [P] [US1] Contract test for markdown template filter behavior in tests/contract/test_markdown_filter.py
|
||||
- [X] T015 [P] [US1] Integration test for feedback detail page rendering with markdown in tests/integration/test_markdown_rendering.py
|
||||
|
||||
**Checkpoint**: All 13 tests written and failing - proceed to implementation
|
||||
|
||||
### Implementation for User Story 1
|
||||
|
||||
- [X] T016 [US1] Create app/utils/markdown_utils.py with markdown_filter function implementing conversion, sanitization, link security, and error handling per plan.md specifications
|
||||
- [X] T017 [US1] Register markdown filter in app/__init__.py create_app function (add app.jinja_env.filters['markdown'] = markdown_filter)
|
||||
- [X] T018 [US1] Update app/templates/dashboard/detail.html line 105 to use markdown filter (change {{ feedback.analysis|safe }} to {{ feedback.analysis|markdown(feedback.feedback_id) }})
|
||||
|
||||
**Checkpoint**: Run all tests - verify they now PASS. User Story 1 complete and independently functional.
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: Polish & Cross-Cutting Concerns
|
||||
|
||||
**Purpose**: Final validation and documentation
|
||||
|
||||
- [X] T019 Run full test suite to verify no regressions (pytest tests/ -v) - ✅ COMPLETE: 123/128 tests passing (96%). All 65 markdown feature tests passing. 4 errors in unrelated performance tests (pre-existing fixture issues).
|
||||
- [X] T020 [P] Manual testing per quickstart.md security verification (XSS prevention, link attributes) - ✅ COMPLETE: All security features verified. XSS protection working (scripts/iframes removed), links have proper security attributes (target="_blank", rel="noopener noreferrer nofollow").
|
||||
- [X] T021 [P] Performance validation: verify feedback detail page load < 2 seconds with complex markdown - ✅ COMPLETE: Page load performance verified < 2 seconds with complex markdown content (30+ sections).
|
||||
|
||||

|
||||
|
||||
## Dependencies & Execution Order
|
||||
|
||||
### Phase Dependencies
|
||||
|
||||
- **Setup (Phase 1)**: No dependencies - can start immediately
|
||||
- **Foundational (Phase 2)**: No tasks - proceed directly to User Story
|
||||
- **User Story 1 (Phase 3)**: Depends on Setup completion
|
||||
- **Polish (Phase 4)**: Depends on User Story 1 completion
|
||||
|
||||
### Within User Story 1
|
||||
|
||||
1. **Tests (T003-T015)**: Write ALL tests first, verify they FAIL
|
||||
2. **Implementation (T016-T018)**: Implement in order (utils → filter registration → template usage)
|
||||
3. **Validation**: Run tests, verify they PASS
|
||||
|
||||
### Parallel Opportunities
|
||||
|
||||
```bash
|
||||
# Phase 1: Sequential (dependency installation)
|
||||
T001 → T002
|
||||
|
||||
# Phase 3: All tests can be written in parallel
|
||||
T003, T004, T005, T006, T007, T008, T009, T010, T011, T012, T013, T014, T015
|
||||
|
||||
# Phase 3: Implementation must be sequential
|
||||
T016 → T017 → T018
|
||||
|
||||
# Phase 4: Polish tasks can run in parallel
|
||||
T020, T021
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Parallel Example: User Story 1 Tests
|
||||
|
||||
Launch all unit tests together (different test functions, same file structure):
|
||||
|
||||
```bash
|
||||
Task: "Unit test for markdown conversion with None/empty input"
|
||||
Task: "Unit test for markdown headings conversion"
|
||||
Task: "Unit test for markdown lists conversion"
|
||||
Task: "Unit test for markdown bold/italic conversion"
|
||||
Task: "Unit test for markdown code blocks conversion"
|
||||
Task: "Unit test for markdown tables conversion"
|
||||
Task: "Unit test for markdown links with security attributes"
|
||||
Task: "Unit test for XSS prevention"
|
||||
Task: "Unit test for image/embedded content exclusion"
|
||||
Task: "Unit test for fallback to preformatted block"
|
||||
Task: "Unit test for warning logs"
|
||||
Task: "Contract test for template filter"
|
||||
Task: "Integration test for page rendering"
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Implementation Strategy
|
||||
|
||||
### MVP First (User Story 1 Only - This Feature IS the MVP)
|
||||
|
||||
1. **Phase 1**: Setup (T001-T002) - Add dependencies
|
||||
2. **Phase 3**: User Story 1
|
||||
- Write ALL tests first (T003-T015) - **verify they FAIL**
|
||||
- Implement utility module (T016)
|
||||
- Register filter (T017)
|
||||
- Update template (T018)
|
||||
- **Run tests - verify they PASS**
|
||||
3. **Phase 4**: Polish (T019-T021) - Validation
|
||||
4. **STOP and VALIDATE**: Test independently, deploy/demo
|
||||
|
||||
### Test-First Workflow (MANDATORY per Constitution)
|
||||
|
||||
For EACH implementation task:
|
||||
1. Write test that captures requirement
|
||||
2. Run test → **MUST FAIL** (proves it tests something)
|
||||
3. Implement minimum code to make test pass
|
||||
4. Run test → **MUST PASS**
|
||||
5. Refactor while keeping test green
|
||||

|
||||
|
||||
## Task Summary
|
||||
|
||||
**Total Tasks**: 21
|
||||
- **Setup**: 2 tasks
|
||||
- **User Story 1 Tests**: 13 tasks (T003-T015)
|
||||
- **User Story 1 Implementation**: 3 tasks (T016-T018)
|
||||
- **Polish**: 3 tasks (T019-T021)
|
||||
|
||||
**Parallel Opportunities**: 13 tests can run in parallel, 2 polish tasks can run in parallel
|
||||
|
||||
**Critical Path**: T001 → T002 → T003-T015 (parallel) → T016 → T017 → T018 → T019 → T020+T021 (parallel)
|
||||
|
||||
**Independent Test Criteria for User Story 1**:
|
||||
- Navigate to feedback detail page with AI analysis
|
||||
- Verify headings rendered as styled HTML (not `##`)
|
||||
- Verify lists have bullets/numbers
|
||||
- Verify bold/italic formatting applied
|
||||
- Verify code displayed in monospace with background
|
||||
- Verify tables formatted with rows/columns
|
||||
- Verify links clickable with `target="_blank"` and `rel="noopener noreferrer nofollow"`
|
||||
- Verify XSS attempts (scripts/iframes) are stripped
|
||||
- Verify images/embeds excluded from output
|
||||
- Verify page loads in < 2 seconds
|
||||
|
||||
**Suggested MVP Scope**: Complete all of Phase 3 (this feature has only one user story - it IS the MVP)

## Notes
|
||||
|
||||
- [P] tasks = Can run in parallel (different files or independent test functions)
|
||||
- [US1] label = Task belongs to User Story 1
|
||||
- Test-first discipline enforced: ALL tests (T003-T015) MUST be written and verified failing BEFORE implementation (T016-T018) begins
|
||||
- Each task has exact file path for clarity
|
||||
- Verify tests fail before implementing (Constitution requirement)
|
||||
- Commit after each task or logical group
|
||||
- This is a simple feature (1 utility file + 1 filter registration + 1 template change) but follows full TDD discipline
