+- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.

+**Steps**
+Track these steps as TODOs and complete them one by one.
+1. Read `changes/<id>/proposal.md`, `design.md` (if present), and `tasks.md` to confirm scope and acceptance criteria.
+2. Work through tasks sequentially, keeping edits minimal and focused on the requested change.
+3. Confirm completion before updating statuses—make sure every item in `tasks.md` is finished.
+4. Update the checklist after all work is done so each task is marked `- [x]` and reflects reality.
+5. Reference `openspec list` or `openspec show <item>` when additional context is required.
+

+- Use `openspec show <id> --json --deltas-only` if you need additional context from the proposal while implementing.

+**Guardrails**
+- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
+- Keep changes tightly scoped to the requested outcome.
+- Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
+
+**Steps**
+1. Determine the change ID to archive:
+   - If this prompt already includes a specific change ID (for example inside a `<ChangeId>` block populated by slash-command arguments), use that value after trimming whitespace.
+   - If the conversation references a change loosely (for example by title or summary), run `openspec list` to surface likely IDs, share the relevant candidates, and confirm which one the user intends.
+   - Otherwise, review the conversation, run `openspec list`, and ask the user which change to archive; wait for a confirmed change ID before proceeding.
+   - If you still cannot identify a single change ID, stop and tell the user you cannot archive anything yet.
+2. Validate the change ID by running `openspec list` (or `openspec show <id>`) and stop if the change is missing, already archived, or otherwise not ready to archive.
+3. Run `openspec archive <id> --yes` so the CLI moves the change and applies spec updates without prompts (use `--skip-specs` only for tooling-only work).
+4. Review the command output to confirm the target specs were updated and the change landed in `changes/archive/`.
+5. Validate with `openspec validate --strict` and inspect with `openspec show <id>` if anything looks off.
+
+**Reference**
+- Use `openspec list` to confirm change IDs before archiving.
+- Inspect refreshed specs with `openspec list --specs` and address any validation issues before handing off.

+description: Scaffold a new OpenSpec change and validate strictly.
+category: OpenSpec
+tags: [openspec, change]
+---
+<!-- OPENSPEC:START -->
+**Guardrails**
+- Favor straightforward, minimal implementations first and add complexity only when it is requested or clearly required.
+- Keep changes tightly scoped to the requested outcome.
+- Refer to `openspec/AGENTS.md` (located inside the `openspec/` directory—run `ls openspec` or `openspec update` if you don't see it) if you need additional OpenSpec conventions or clarifications.
+- Identify any vague or ambiguous details and ask the necessary follow-up questions before editing files.
+
+**Steps**
+1. Review `openspec/project.md`, run `openspec list` and `openspec list --specs`, and inspect related code or docs (e.g., via `rg`/`ls`) to ground the proposal in current behaviour; note any gaps that require clarification.
+2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, and `design.md` (when needed) under `openspec/changes/<id>/`.
+3. Map the change into concrete capabilities or requirements, breaking multi-scope efforts into distinct spec deltas with clear relationships and sequencing.
+4. Capture architectural reasoning in `design.md` when the solution spans multiple systems, introduces new patterns, or demands trade-off discussion before committing to specs.
+5. Draft spec deltas in `changes/<id>/specs/<capability>/spec.md` (one folder per capability) using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement and cross-reference related capabilities when relevant.
+6. Draft `tasks.md` as an ordered list of small, verifiable work items that deliver user-visible progress, include validation (tests, tooling), and highlight dependencies or parallelizable work.
+7. Validate with `openspec validate <id> --strict` and resolve every issue before sharing the proposal.
+
+**Reference**
+- Use `openspec show <id> --json --deltas-only` or `openspec show <spec> --type spec` to inspect details when validation fails.
+- Search existing requirements with `rg -n "Requirement:|Scenario:" openspec/specs` before writing new ones.
+- Explore the codebase with `rg <keyword>`, `ls`, or direct file reads so proposals align with current implementation realities.

+# Hugo Site Implementation Summary
+
+## What Was Implemented
+
+### ✅ Hugo Project Structure
+- Initialized Hugo site with standard directory structure
+- Created `hugo.toml` configuration file with site settings
+- All required directories in place: layouts/, content/, static/, data/, assets/
+
+### ✅ Layout Templates

+   - Base template with HTML5 structure
+   - Bootstrap 5.3.2 CSS/JS integration via CDN
+   - Responsive viewport configuration
+   - Blocks for header, main content, and footer
+
+2. **index.html** (`layouts/index.html`)
+   - Homepage template
+   - Uses Bootstrap container and grid system
+   - Responsive layout (col-lg-8 offset-lg-2)
+
+3. **single.html** (`layouts/_default/single.html`)
+   - Template for individual content pages
+   - Displays title, date, and content
+   - Same responsive layout as homepage
+
+### ✅ Partials
+1. **header.html** (`layouts/partials/header.html`)
+   - Bootstrap navbar with site branding

+- Mobile-first design approach
+
+### ✅ Content Files (Placeholders)
+- `content/_index.md` - Homepage content (placeholder)
+- `content/about.md` - About page (placeholder)
+- `static/README.md` - Guide for placing static assets
+
+### ✅ Configuration

+- See `docs/TAXONOMIES.md` for how to re-enable when adding a blog
+
+### ✅ Testing & Validation
+- Hugo builds successfully without errors
+- Generated HTML is valid HTML5
+- Semantic HTML structure (header, nav, main, footer, article)
+- Responsive viewport meta tags present
+- Bootstrap responsive classes applied
+- Basic accessibility features (aria-labels, semantic elements)
+
+## Generated Files
+
+The `hugo` command generates a `public/` directory with:
+- `index.html` - Homepage
+- `about/index.html` - About page
+- `index.xml` - RSS feed
+- `sitemap.xml` - Sitemap
+- All static assets
+
+## How to Use
+
+### Local Development
+```bash
+# Start Hugo development server with live reload
+hugo server -D
+
+# Access the site at http://localhost:1313
+```
+
+### Build for Production
+```bash
+# Build the site (output in public/)
+hugo
+
+# The public/ directory can be deployed to any static hosting
+```
+
+### Add Content
+1. Create new content files:
+   ```bash
+   hugo new content/page-name.md
+   ```
+
+2. Edit the markdown file with front matter:
+   ```markdown
+   ---
+   title: "Page Title"
+   date: 2024-10-27
+   description: "Page description"
+   ---
+
+   Your content here in markdown format.
+   ```
+
+### Add Navigation Links
+Edit `hugo.toml` to add menu items:
+```toml
+[menu]
+  [[menu.main]]
+    name = "About"
+    url = "/about/"
+    weight = 1
+  [[menu.main]]
+    name = "Contact"
+    url = "/contact/"
+    weight = 2
+```
+
+## Next Steps
+
+### Required: Replace Placeholder Content
+1. **Copy content from markusgraf.ch**
+   - Update `content/_index.md` with actual homepage content
+   - Update `content/about.md` with actual about content
+   - Create additional content pages as needed
+
+2. **Migrate static assets**
+   - Copy images to `static/images/`
+   - Copy fonts to `static/fonts/`
+   - Copy any custom CSS to `static/css/`
+   - Add favicon to `static/`
+
+### Optional Enhancements
+1. **Customize styling**
+   - Create `static/css/custom.css` for additional styles
+   - Link it in baseof.html `{{ block "head" . }}` section
+
+2. **Add list template** (for future blog)
+   - Create `layouts/_default/list.html` when needed
+
+3. **Configure menus**
+   - Add navigation links to `hugo.toml`
+
+4. **Add shortcodes**
+   - Create custom Hugo shortcodes in `layouts/shortcodes/`

+# Hugo Taxonomies Guide
+
+## Current Status
+
+Taxonomies (categories and tags) are **currently disabled** in this Hugo site to keep it minimal.
+
+## What Are Taxonomies?
+
+Hugo taxonomies are classification systems for your content:
+- **Categories** - Broad groupings (e.g., "Technology", "Personal", "Projects")
+- **Tags** - Specific keywords (e.g., "golang", "web-development", "tutorial")
+
+They're useful for blogs and content-heavy sites where visitors need to filter and find related content.
+
+## Why Are They Disabled?
+
+For a minimal personal website without a blog, taxonomies add unnecessary complexity:
+- Creates extra pages (`/categories/`, `/tags/`) that aren't used
+- Requires additional template files
+- Generates warning messages during builds
+
+## How to Re-enable Taxonomies
+
+When you're ready to add a blog or need content categorization:
+
+### Step 1: Enable Taxonomies in Configuration
+
+Edit `hugo.toml` and **remove** or **comment out** this line:
+
+```toml
+# Remove this line:
+disableKinds = ['taxonomy', 'term']
+```
+
+Or comment it out to keep for reference:
+
+```toml
+# Taxonomies disabled for minimal site - uncomment to enable:
+# disableKinds = ['taxonomy', 'term']
+```
+
+### Step 2: Create Taxonomy Templates
+
+Create two template files in `layouts/_default/`:
+
+#### `layouts/_default/taxonomy.html`
+This template displays all content items for a single category or tag.
+
+```html
+{{ define "main" }}
+<div class="container">
+  <div class="row">
+    <div class="col-lg-8 offset-lg-2">
+      <header class="mt-5 mb-4">
+        <h1 class="display-4">{{ .Title }}</h1>
+        <p class="lead text-muted">{{ .Data.Plural }}: {{ len .Pages }} {{ if eq (len .Pages) 1 }}item{{ else }}items{{ end }}</p>
+      </header>
+
+      <div class="list-group">
+        {{ range .Pages }}
+        <a href="{{ .RelPermalink }}" class="list-group-item list-group-item-action">
+          <div class="d-flex w-100 justify-content-between">
+            <h5 class="mb-1">{{ .Title }}</h5>
+            <small class="text-muted">{{ .Date.Format "Jan 2, 2006" }}</small>
+          </div>
+          {{ if .Description }}
+          <p class="mb-1">{{ .Description }}</p>
+          {{ end }}
+        </a>
+        {{ end }}
+      </div>
+    </div>
+  </div>
+</div>
+{{ end }}
+```
+
+#### `layouts/_default/terms.html`
+This template lists all available categories or all available tags.
+
+```html
+{{ define "main" }}
+<div class="container">
+  <div class="row">
+    <div class="col-lg-8 offset-lg-2">
+      <header class="mt-5 mb-4">
+        <h1 class="display-4">{{ .Title }}</h1>
+        <p class="lead text-muted">Browse all {{ .Data.Plural | lower }}</p>
+      </header>
+
+      <div class="row">
+        {{ range .Pages }}
+        <div class="col-md-6 mb-3">
+          <div class="card">
+            <div class="card-body">
+              <h5 class="card-title">
+                <a href="{{ .RelPermalink }}">{{ .Title }}</a>
+              </h5>
+              <p class="card-text text-muted">{{ len .Pages }} {{ if eq (len .Pages) 1 }}post{{ else }}posts{{ end }}</p>
+            </div>
+          </div>
+        </div>
+        {{ end }}
+      </div>
+    </div>
+  </div>
+</div>
+{{ end }}
+```
+
+### Step 3: Add Taxonomies to Content
+
+Add categories and tags to your content front matter:
+
+```markdown
+---
+title: "My Blog Post"
+date: 2024-10-27
+categories:
+  - Technology
+  - Web Development
+tags:
+  - hugo
+  - golang
+  - static-sites
+---
+
+Your content here...
+```
+
+### Step 4: Optional - Configure Menu Links
+
+Add taxonomy pages to your navigation in `hugo.toml`:
+
+```toml
+[menu]
+  [[menu.main]]
+    name = "Categories"
+    url = "/categories/"
+    weight = 10
+  [[menu.main]]
+    name = "Tags"
+    url = "/tags/"
+    weight = 20
+```
+
+### Step 5: Optional - Customize Taxonomy Names
+
+If you want different taxonomy names (e.g., "Topics" instead of "Categories"):
+
+```toml
+[taxonomies]
+  topic = "topics"
+  tag = "tags"
+```
+
+Then use in front matter:
+
+```markdown
+---
+topics:
+  - Web Development
+tags:
+  - hugo
+---
+```
+
+## Testing After Re-enabling
+
+After re-enabling and creating templates:
+
+```bash
+# Build the site
+hugo
+
+# Start the server
+hugo server -D
+
+# Visit in browser:
+# http://localhost:1313/categories/
+# http://localhost:1313/tags/
+# http://localhost:1313/categories/technology/
+# http://localhost:1313/tags/hugo/
+```
+
+You should see:
+- No warnings in build output
+- Category and tag listing pages
+- Individual category/tag pages showing filtered content
+
+## Custom Taxonomies
+
+Hugo supports custom taxonomies beyond categories and tags:
+
+```toml
+[taxonomies]
+  category = "categories"
+  tag = "tags"
+  series = "series"        # For blog post series
+  author = "authors"       # For multi-author blogs
+  project = "projects"     # For portfolio sites
+```
+
+Use in content:
+
+```markdown
+---
+series: ["Getting Started with Hugo"]
+authors: ["Markus Graf"]
+projects: ["Personal Website"]
+---
+```

+# OpenSpec Instructions
+
+Instructions for AI coding assistants using OpenSpec for spec-driven development.
+
+## TL;DR Quick Checklist
+
+- Search existing work: `openspec spec list --long`, `openspec list` (use `rg` only for full-text search)
+- Decide scope: new capability vs modify existing capability
+- Pick a unique `change-id`: kebab-case, verb-led (`add-`, `update-`, `remove-`, `refactor-`)
+- Scaffold: `proposal.md`, `tasks.md`, `design.md` (only if needed), and delta specs per affected capability
+- Write deltas: use `## ADDED|MODIFIED|REMOVED|RENAMED Requirements`; include at least one `#### Scenario:` per requirement
+- Validate: `openspec validate [change-id] --strict` and fix issues
+- Request approval: Do not start implementation until proposal is approved
+
+## Three-Stage Workflow
+
+### Stage 1: Creating Changes
+Create proposal when you need to:
+- Add features or functionality
+- Make breaking changes (API, schema)
+- Change architecture or patterns  
+- Optimize performance (changes behavior)
+- Update security patterns
+
+Triggers (examples):
+- "Help me create a change proposal"
+- "Help me plan a change"
+- "Help me create a proposal"
+- "I want to create a spec proposal"
+- "I want to create a spec"
+
+Loose matching guidance:
+- Contains one of: `proposal`, `change`, `spec`
+- With one of: `create`, `plan`, `make`, `start`, `help`
+
+Skip proposal for:
+- Bug fixes (restore intended behavior)
+- Typos, formatting, comments
+- Dependency updates (non-breaking)
+- Configuration changes
+- Tests for existing behavior
+
+**Workflow**
+1. Review `openspec/project.md`, `openspec list`, and `openspec list --specs` to understand current context.
+2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, optional `design.md`, and spec deltas under `openspec/changes/<id>/`.
+3. Draft spec deltas using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement.
+4. Run `openspec validate <id> --strict` and resolve any issues before sharing the proposal.
+
+### Stage 2: Implementing Changes
+Track these steps as TODOs and complete them one by one.
+1. **Read proposal.md** - Understand what's being built
+2. **Read design.md** (if exists) - Review technical decisions
+3. **Read tasks.md** - Get implementation checklist
+4. **Implement tasks sequentially** - Complete in order
+5. **Confirm completion** - Ensure every item in `tasks.md` is finished before updating statuses
+6. **Update checklist** - After all work is done, set every task to `- [x]` so the list reflects reality
+7. **Approval gate** - Do not start implementation until the proposal is reviewed and approved
+
+### Stage 3: Archiving Changes
+After deployment, create separate PR to:
+- Move `changes/[name]/` → `changes/archive/YYYY-MM-DD-[name]/`
+- Update `specs/` if capabilities changed
+- Use `openspec archive <change-id> --skip-specs --yes` for tooling-only changes (always pass the change ID explicitly)
+- Run `openspec validate --strict` to confirm the archived change passes checks
+
+## Before Any Task
+
+**Context Checklist:**
+- [ ] Read relevant specs in `specs/[capability]/spec.md`
+- [ ] Check pending changes in `changes/` for conflicts
+- [ ] Read `openspec/project.md` for conventions
+- [ ] Run `openspec list` to see active changes
+- [ ] Run `openspec list --specs` to see existing capabilities
+
+**Before Creating Specs:**
+- Always check if capability already exists
+- Prefer modifying existing specs over creating duplicates
+- Use `openspec show [spec]` to review current state
+- If request is ambiguous, ask 1–2 clarifying questions before scaffolding
+
+### Search Guidance
+- Enumerate specs: `openspec spec list --long` (or `--json` for scripts)
+- Enumerate changes: `openspec list` (or `openspec change list --json` - deprecated but available)
+- Show details:
+  - Spec: `openspec show <spec-id> --type spec` (use `--json` for filters)
+  - Change: `openspec show <change-id> --json --deltas-only`
+- Full-text search (use ripgrep): `rg -n "Requirement:|Scenario:" openspec/specs`
+
+## Quick Start
+
+### CLI Commands
+
+```bash
+# Essential commands
+openspec list                  # List active changes
+openspec list --specs          # List specifications
+openspec show [item]           # Display change or spec
+openspec validate [item]       # Validate changes or specs
+openspec archive <change-id> [--yes|-y]   # Archive after deployment (add --yes for non-interactive runs)
+
+# Project management
+openspec init [path]           # Initialize OpenSpec
+openspec update [path]         # Update instruction files
+
+# Interactive mode
+openspec show                  # Prompts for selection
+openspec validate              # Bulk validation mode
+
+# Debugging
+openspec show [change] --json --deltas-only
+openspec validate [change] --strict
+```
+
+### Command Flags
+
+- `--json` - Machine-readable output
+- `--type change|spec` - Disambiguate items
+- `--strict` - Comprehensive validation
+- `--no-interactive` - Disable prompts
+- `--skip-specs` - Archive without spec updates
+- `--yes`/`-y` - Skip confirmation prompts (non-interactive archive)

+```
+
+## Creating Change Proposals
+
+### Decision Tree
+
+```
+New request?
+├─ Bug fix restoring spec behavior? → Fix directly
+├─ Typo/format/comment? → Fix directly  
+├─ New feature/capability? → Create proposal
+├─ Breaking change? → Create proposal
+├─ Architecture change? → Create proposal
+└─ Unclear? → Create proposal (safer)
+```
+
+### Proposal Structure
+
+1. **Create directory:** `changes/[change-id]/` (kebab-case, verb-led, unique)
+
+2. **Write proposal.md:**
+```markdown
+## Why
+[1-2 sentences on problem/opportunity]
+
+## What Changes
+- [Bullet list of changes]
+- [Mark breaking changes with **BREAKING**]
+
+## Impact
+- Affected specs: [list capabilities]
+- Affected code: [key files/systems]
+```
+
+3. **Create spec deltas:** `specs/[capability]/spec.md`
+```markdown
+## ADDED Requirements
+### Requirement: New Feature
+The system SHALL provide...
+
+#### Scenario: Success case
+- **WHEN** user performs action
+- **THEN** expected result
+
+## MODIFIED Requirements
+### Requirement: Existing Feature
+[Complete modified requirement]
+
+## REMOVED Requirements
+### Requirement: Old Feature
+**Reason**: [Why removing]
+**Migration**: [How to handle]
+```
+If multiple capabilities are affected, create multiple delta files under `changes/[change-id]/specs/<capability>/spec.md`—one per capability.
+
+4. **Create tasks.md:**
+```markdown
+## 1. Implementation
+- [ ] 1.1 Create database schema
+- [ ] 1.2 Implement API endpoint
+- [ ] 1.3 Add frontend component
+- [ ] 1.4 Write tests
+```
+
+5. **Create design.md when needed:**
+Create `design.md` if any of the following apply; otherwise omit it:
+- Cross-cutting change (multiple services/modules) or a new architectural pattern
+- New external dependency or significant data model changes
+- Security, performance, or migration complexity
+- Ambiguity that benefits from technical decisions before coding
+
+Minimal `design.md` skeleton:
+```markdown
+## Context
+[Background, constraints, stakeholders]
+
+## Goals / Non-Goals
+- Goals: [...]
+- Non-Goals: [...]
+
+## Decisions
+- Decision: [What and why]
+- Alternatives considered: [Options + rationale]
+
+## Risks / Trade-offs
+- [Risk] → Mitigation
+
+## Migration Plan
+[Steps, rollback]
+
+## Open Questions
+- [...]
+```
+
+## Spec File Format
+
+### Critical: Scenario Formatting
+
+**CORRECT** (use #### headers):
+```markdown
+#### Scenario: User login success
+- **WHEN** valid credentials provided
+- **THEN** return JWT token
+```
+
+**WRONG** (don't use bullets or bold):
+```markdown
+- **Scenario: User login**  ❌
+**Scenario**: User login     ❌
+### Scenario: User login      ❌
+```
+
+Every requirement MUST have at least one scenario.
+
+### Requirement Wording
+- Use SHALL/MUST for normative requirements (avoid should/may unless intentionally non-normative)
+
+### Delta Operations
+
+- `## ADDED Requirements` - New capabilities
+- `## MODIFIED Requirements` - Changed behavior
+- `## REMOVED Requirements` - Deprecated features
+- `## RENAMED Requirements` - Name changes
+
+Headers matched with `trim(header)` - whitespace ignored.
+
+#### When to use ADDED vs MODIFIED
+- ADDED: Introduces a new capability or sub-capability that can stand alone as a requirement. Prefer ADDED when the change is orthogonal (e.g., adding "Slash Command Configuration") rather than altering the semantics of an existing requirement.
+- MODIFIED: Changes the behavior, scope, or acceptance criteria of an existing requirement. Always paste the full, updated requirement content (header + all scenarios). The archiver will replace the entire requirement with what you provide here; partial deltas will drop previous details.
+- RENAMED: Use when only the name changes. If you also change behavior, use RENAMED (name) plus MODIFIED (content) referencing the new name.
+
+Common pitfall: Using MODIFIED to add a new concern without including the previous text. This causes loss of detail at archive time. If you aren’t explicitly changing the existing requirement, add a new requirement under ADDED instead.
+
+Authoring a MODIFIED requirement correctly:
+1) Locate the existing requirement in `openspec/specs/<capability>/spec.md`.
+2) Copy the entire requirement block (from `### Requirement: ...` through its scenarios).
+3) Paste it under `## MODIFIED Requirements` and edit to reflect the new behavior.
+4) Ensure the header text matches exactly (whitespace-insensitive) and keep at least one `#### Scenario:`.
+
+Example for RENAMED:
+```markdown
+## RENAMED Requirements
+- FROM: `### Requirement: Login`
+- TO: `### Requirement: User Authentication`
+```
+
+## Troubleshooting
+
+### Common Errors
+
+**"Change must have at least one delta"**
+- Check `changes/[name]/specs/` exists with .md files
+- Verify files have operation prefixes (## ADDED Requirements)
+
+**"Requirement must have at least one scenario"**
+- Check scenarios use `#### Scenario:` format (4 hashtags)
+- Don't use bullet points or bold for scenario headers
+
+**Silent scenario parsing failures**
+- Exact format required: `#### Scenario: Name`
+- Debug with: `openspec show [change] --json --deltas-only`
+
+### Validation Tips
+
+```bash
+# Always use strict mode for comprehensive checks
+openspec validate [change] --strict
+
+# Debug delta parsing
+openspec show [change] --json | jq '.deltas'
+
+# Check specific requirement
+openspec show [spec] --json -r 1
+```
+
+## Happy Path Script
+
+```bash
+# 1) Explore current state
+openspec spec list --long
+openspec list
+# Optional full-text search:
+# rg -n "Requirement:|Scenario:" openspec/specs
+# rg -n "^#|Requirement:" openspec/changes
+
+# 2) Choose change id and scaffold
+CHANGE=add-two-factor-auth
+mkdir -p openspec/changes/$CHANGE/{specs/auth}
+printf "## Why\n...\n\n## What Changes\n- ...\n\n## Impact\n- ...\n" > openspec/changes/$CHANGE/proposal.md
+printf "## 1. Implementation\n- [ ] 1.1 ...\n" > openspec/changes/$CHANGE/tasks.md
+
+# 3) Add deltas (example)
+cat > openspec/changes/$CHANGE/specs/auth/spec.md << 'EOF'
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+Users MUST provide a second factor during login.
+
+#### Scenario: OTP required
+- **WHEN** valid credentials are provided
+- **THEN** an OTP challenge is required
+EOF
+
+# 4) Validate
+openspec validate $CHANGE --strict
+```
+
+## Multi-Capability Example
+
+```
+openspec/changes/add-2fa-notify/
+├── proposal.md
+├── tasks.md
+└── specs/
+    ├── auth/
+    │   └── spec.md   # ADDED: Two-Factor Authentication
+    └── notifications/
+        └── spec.md   # ADDED: OTP email notification
+```
+
+auth/spec.md
+```markdown
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+...
+```
+
+notifications/spec.md
+```markdown
+## ADDED Requirements
+### Requirement: OTP Email Notification
+...
+```
+
+## Best Practices
+
+### Simplicity First
+- Default to <100 lines of new code
+- Single-file implementations until proven insufficient
+- Avoid frameworks without clear justification
+- Choose boring, proven patterns
+
+### Complexity Triggers
+Only add complexity with:
+- Performance data showing current solution too slow
+- Concrete scale requirements (>1000 users, >100MB data)
+- Multiple proven use cases requiring abstraction
+
+### Clear References
+- Use `file.ts:42` format for code locations
+- Reference specs as `specs/auth/spec.md`
+- Link related changes and PRs
+
+### Capability Naming
+- Use verb-noun: `user-auth`, `payment-capture`
+- Single purpose per capability
+- 10-minute understandability rule
+- Split if description needs "AND"
+
+### Change ID Naming
+- Use kebab-case, short and descriptive: `add-two-factor-auth`
+- Prefer verb-led prefixes: `add-`, `update-`, `remove-`, `refactor-`
+- Ensure uniqueness; if taken, append `-2`, `-3`, etc.
+
+## Tool Selection Guide
+
+| Task | Tool | Why |
+|------|------|-----|
+| Find files by pattern | Glob | Fast pattern matching |
+| Search code content | Grep | Optimized regex search |
+| Read specific files | Read | Direct file access |
+| Explore unknown scope | Task | Multi-step investigation |
+
+## Error Recovery
+
+### Change Conflicts
+1. Run `openspec list` to see active changes
+2. Check for overlapping specs
+3. Coordinate with change owners
+4. Consider combining proposals
+
+### Validation Failures
+1. Run with `--strict` flag
+2. Check JSON output for details
+3. Verify spec file format
+4. Ensure scenarios properly formatted
+
+### Missing Context
+1. Read project.md first
+2. Check related specs
+3. Review recent archives
+4. Ask for clarification

+## Context
+Converting an existing static HTML website (markusgraf.ch) to Hugo to enable template-based content management. The current site uses Bootstrap for styling, which will be preserved and upgraded to Bootstrap 5.x. This is a greenfield Hugo implementation with no existing templating infrastructure.
+
+## Goals / Non-Goals
+### Goals
+- Create a maintainable Hugo project structure
+- Preserve current website content and design
+- Enable easy content updates through templates
+- Establish foundation for future CV and blog sections
+- Upgrade Bootstrap to latest 5.x version
+
+### Non-Goals
+- Redesigning the website appearance
+- Adding new content sections (CV, blog) in this change
+- Implementing JavaScript features
+- Setting up automated deployment pipelines
+- SEO optimization
+
+## Decisions
+
+### Hugo Configuration Format
+**Decision**: Use `hugo.toml` (TOML format) for configuration.
+
+**Rationale**: TOML is Hugo's default and most commonly used format, providing good readability for simple configurations.
+
+**Alternatives considered**:
+- YAML: More verbose for simple configs, but we'll keep it as an option if complex nested structures are needed later
+- JSON: Less human-readable for configuration files
+
+### Bootstrap Integration Method
+**Decision**: Use CDN links for Bootstrap CSS in the base layout template.
+
+**Rationale**:
+- Simplest approach for static site
+- No build process needed for CSS
+- Fast loading via CDN
+- Easy to upgrade versions
+
+**Alternatives considered**:
+- Local Bootstrap files: Adds unnecessary files to repository
+- Hugo Pipes with SCSS: Overkill for current needs (no custom SCSS)
+- npm integration: Unnecessary complexity without JavaScript build needs
+
+### Template Organization
+**Decision**: Use standard Hugo template hierarchy with baseof.html and minimal partials.
+
+**Rationale**:
+- Follows Hugo best practices
+- Keeps templates DRY (Don't Repeat Yourself)
+- Makes future extensions straightforward
+- Header, footer, and nav are natural partial candidates
+
+**Structure**:
+```
+layouts/
+├── _default/
+│   ├── baseof.html      # Base template with Bootstrap integration
+│   ├── single.html      # Single page template
+│   └── list.html        # List template (future blog)
+├── index.html           # Homepage template
+└── partials/
+    ├── header.html      # Site header with nav
+    ├── footer.html      # Site footer
+    └── nav.html         # Navigation menu
+```
+
+### Content Structure
+**Decision**: Start with simple markdown files in `/content` directory, one file per page.
+
+**Rationale**:
+- Simple and sufficient for current needs
+- Easy to understand and maintain
+- Can evolve to page bundles when needed for CV/blog
+
+## Risks / Trade-offs
+
+### Risk: Bootstrap CDN Availability
+**Mitigation**: Use well-established CDN (jsDelivr or official Bootstrap CDN) with high uptime. Can switch to local files later if needed.
+
+### Risk: Content Migration Accuracy
+**Mitigation**: Manual review of each page after conversion. Keep reference to original HTML during development.
+
+### Trade-off: CDN vs Local Assets
+**Chosen**: CDN for simplicity and performance
+**Trade-off**: Slight dependency on external service, but acceptable for personal site
+
+## Migration Plan
+
+### Phase 1: Setup (Tasks 1.1-1.3)
+1. Run `hugo new site` to scaffold structure
+2. Create and configure hugo.toml
+3. Verify directory structure
+
+### Phase 2: Templates (Tasks 2.1-3.3)
+1. Build baseof.html with Bootstrap CDN links
+2. Create homepage template based on current site
+3. Create reusable partials
+4. Test template rendering with placeholder content
+
+### Phase 3: Content (Tasks 5.1-5.3)
+1. Review and document current site structure
+2. Create markdown content files
+3. Copy static assets to `/static` directory
+
+### Phase 4: Validation (Tasks 6.1-6.5)
+1. Build site with `hugo`
+2. Run local server with `hugo server`
+3. Test all pages and responsive behavior
+4. Validate HTML and accessibility
+
+### Rollback
+If Hugo migration fails or is unsatisfactory:
+- Original static HTML is preserved separately
+- Can revert to static hosting immediately
+- No database or external dependencies to roll back
+
+## Open Questions
+None at this time. Implementation is straightforward following Hugo conventions.

+## Why
+The current markusgraf.ch website uses static HTML files. Converting to Hugo will provide a maintainable template-based structure that simplifies future content updates and enables easy addition of new sections (CV, blog) without duplicating code.
+
+## What Changes
+- Initialize Hugo project structure with standard directories
+- Create base layout template with Bootstrap 5.x integration
+- Set up reusable partials (header, footer, navigation)
+- Convert existing HTML content to Hugo templates
+- Configure Hugo site settings
+- Add static assets from current website
+
+## Impact
+- Affected specs: hugo-site (new capability)
+- Affected code: This is a greenfield implementation - no existing code affected
+- Migration: Current static HTML will be referenced to recreate in Hugo templates

+#### Scenario: Semantic HTML structure
+- **WHEN** pages are rendered
+- **THEN** content uses appropriate semantic elements (header, nav, main, footer, article)
+- **AND** maintains logical heading hierarchy (h1, h2, h3)
+
+#### Scenario: Navigation accessibility
+- **WHEN** keyboard navigation is used
+- **THEN** all interactive elements are focusable
+- **AND** focus order is logical

+# Project Context
+
+## Purpose
+Converting the existing static HTML website at markusgraf.ch into a Hugo-based static site. This project maintains the current content while establishing a foundation for future expansion with CV and blog sections.
+
+## Tech Stack
+- **Static Site Generator**: Hugo (latest stable version)
+- **Templating**: Go templates (Hugo's templating engine)
+- **Styling**: Bootstrap (upgrading from current version to latest Bootstrap 5.x)
+- **Scripting**: None (no JavaScript/TypeScript at this stage)
+- **Deployment**: Static HTML output
+- **Version Control**: Git
+
+## Project Conventions
+
+### Code Style
+- Use semantic HTML5 elements
+- Follow Hugo best practices for template organization
+- Use consistent indentation (2 spaces) in HTML and templates
+- Keep templates DRY (Don't Repeat Yourself) using partials
+- Use descriptive names for partials and layouts
+- Comment complex template logic
+
+### Architecture Patterns
+- **Hugo Structure**: Follow standard Hugo directory structure
+  - `/layouts` - Template files (baseof.html, partials, shortcodes)
+  - `/content` - Markdown content files
+  - `/static` - Static assets (images, fonts, etc.)
+  - `/assets` - Files to be processed (SCSS, if needed)
+  - `/data` - Data files (YAML, JSON, TOML)
+  - `/config.toml` (or config.yaml) - Site configuration
+- **Template Hierarchy**: Use Hugo's template lookup order effectively
+- **Partials**: Break down templates into reusable partials (header, footer, nav, etc.)
+- **Content Organization**: Use page bundles and sections as appropriate
+
+### Testing Strategy
+- No automated testing currently implemented
+- Manual testing in browsers for layout and functionality
+- Playwright for E2E testing will be introduced in a future phase
+
+### Git Workflow
+- **Branching**: Feature branches from `main` (e.g., `feature/convert-homepage`)
+- **Commits**: Conventional commits format (feat:, fix:, docs:, refactor:, etc.)
+- **PRs**: Required for all changes, squash and merge
+- **Branch Protection**: Main branch requires review
+
+## Domain Context
+Currently migrating existing markusgraf.ch content to Hugo:
+- Existing static HTML pages and content
+- Current design and layout using Bootstrap
+
+Future planned additions:
+- Curriculum Vitae (CV) page
+- Blog section
+
+The migration focuses on preserving current content and functionality while establishing a maintainable Hugo foundation.
+
+## Important Constraints
+- Must be performant (Lighthouse score >90)
+- Must be accessible (WCAG 2.1 AA compliance)
+- Must be responsive (mobile-first design)
+- Keep output file size minimal
+
+## External Dependencies
+None currently required. Site is fully self-contained static HTML.

+# Static Assets
+
+Place your static assets in this directory. They will be available at the root of your site.
+
+## Directory Structure
+
+```
+static/
+├── images/       # Place images here (will be accessible at /images/)
+├── fonts/        # Place custom fonts here (will be accessible at /fonts/)
+├── css/          # Place custom CSS files here (will be accessible at /css/)
+└── favicon.ico   # Place favicon at root
+```
+
+## Examples
+
+- `static/images/logo.png` → accessible at `/images/logo.png`
+- `static/favicon.ico` → accessible at `/favicon.ico`
+- `static/css/custom.css` → accessible at `/css/custom.css`
+
+Copy your existing markusgraf.ch static assets (images, fonts, etc.) into the appropriate subdirectories.
