+## Wave 3, Task 9: Create Basecamp Integration Skill
+
+### Skill Structure Pattern for MCP Integrations
+
+The Basecamp skill follows the standard pattern from skill-creator with MCP-specific adaptations:
+
+1. **YAML frontmatter** with comprehensive trigger list
+   - name: `basecamp`
+   - description: Includes all use cases and trigger keywords
+   - compatibility: `opencode`
+
+2. **Core Workflows** organized by functionality categories
+   - Finding Projects and Todos
+   - Managing Card Tables (Kanban)
+   - Working with Messages and Campfire
+   - Managing Inbox (Email Forwards)
+   - Documents
+   - Webhooks and Automation
+   - Daily Check-ins
+   - Attachments and Events
+
+3. **Integration with Other Skills** section for agent handoff
+   - Documents Hermes (work communication agent) usage patterns
+   - Table showing user request → Hermes action → Basecamp tools used
+   - Common workflow patterns for project setup, task management, communication
+
+### Basecamp MCP Tool Organization (63 Tools)
+
+**Tools grouped by category:**
+
+1. **Projects & Lists (5 tools):**
+   - `get_projects`, `get_project`, `get_todolists`, `get_todos`, `search_basecamp`
+
+2. **Card Table/Kanban (26 tools):**
+   - Column management: `get_card_table`, `get_columns`, `get_column`, `create_column`, `update_column`, `move_column`, `update_column_color`, `put_column_on_hold`, `remove_column_hold`, `watch_column`, `unwatch_column`
+   - Card management: `get_cards`, `get_card`, `create_card`, `update_card`, `move_card`, `complete_card`, `uncomplete_card`
+   - Step (sub-task) management: `get_card_steps`, `create_card_step`, `get_card_step`, `update_card_step`, `delete_card_step`, `complete_card_step`, `uncomplete_card_step`
+
+3. **Messages & Communication (5 tools):**
+   - `get_message_board`, `get_messages`, `get_message`, `get_campfire_lines`, `get_comments`, `create_comment`
+
+4. **Inbox/Email Forwards (6 tools):**
+   - `get_inbox`, `get_forwards`, `get_forward`, `get_inbox_replies`, `get_inbox_reply`, `trash_forward`
+
+5. **Documents (5 tools):**
+   - `get_documents`, `get_document`, `create_document`, `update_document`, `trash_document`
+
+6. **Webhooks (3 tools):**
+   - `get_webhooks`, `create_webhook`, `delete_webhook`
+
+7. **Other (4 tools):**
+   - `get_daily_check_ins`, `get_question_answers`, `create_attachment`, `get_events`
+
+### Skill Content Design Principles
+
+**Concise but comprehensive:**
+- Tool reference lists use bullet points for readability
+- Workflow examples show command usage patterns
+- Categories separate concerns (projects vs card tables vs communication)
+- Integration table maps user requests to specific tool usage
+
+**Progressive disclosure:**
+- Core workflows organized by category, not alphabetical
+- Each workflow shows tool commands with parameters
+- Integration section focuses on Hermes agent handoff
+- Tool organization table provides quick reference
+
+**Appropriate degrees of freedom:**
+- Low freedom: Tool command patterns (must use correct parameters)
+- Medium freedom: Workflow selection (multiple valid approaches)
+- High freedom: Project structure design (varies by organization)
+
+### Verification Commands
+
+**File structure:**
+```bash
+test -d skills/basecamp && test -f skills/basecamp/SKILL.md
+# Expected output: ✅ File structure valid
+```
+
+**YAML frontmatter validation:**
+```bash
+python3 -c "import yaml; f = open('skills/basecamp/SKILL.md'); content = f.read(); f.close(); yaml.safe_load(content.split('---')[1])"
+# Expected output: ✅ YAML frontmatter valid
+```
+
+**Field verification:**
+```bash
+python3 -c "import yaml; f = open('skills/basecamp/SKILL.md'); content = f.read(); f.close(); frontmatter = yaml.safe_load(content.split('---')[1]); print('name:', frontmatter.get('name')); print('compatibility:', frontmatter.get('compatibility'))"
+# Expected output: name: basecamp, compatibility: opencode
+```
+
+### Key Takeaways
+
+- MCP integration skills need comprehensive tool categorization (63 tools in Basecamp)
+- Integration sections should map agent workflows to specific tools (Hermes uses Basecamp for project tasks)
+- Card table workflows are complex (26 tools for kanban management) - need detailed sub-sections
+- YAML frontmatter must include all trigger keywords for skill activation
+- Tool organization tables help agents find the right tool quickly
+- Workflow examples should show actual command syntax with parameters
+- Skills document MCP tool names, not setup or authentication (managed by Nix)
+
+
+## Wave 3, Task 12: Create Outlook email integration skill
+
+### Skill Creation Pattern for MCP Integration Skills
+
+**Structure pattern for MCP-based skills:**
+1. **YAML frontmatter**: name, description (with triggers), compatibility: opencode
+2. **Overview**: High-level description of domain and capabilities
+3. **Core Workflows**: Numbered step-by-step processes for common operations
+4. **Advanced Features**: Optional capabilities that enhance basic workflows
+5. **Integration with Other Skills**: Table showing domain boundaries and handoffs
+6. **Common Patterns**: Reusable workflow patterns
+7. **Quality Standards**: Output criteria and best practices
+8. **Edge Cases**: Exception handling
+9. **Boundaries**: Explicit domain separation with agent attribution
+
+### Outlook-Specific Domain Coverage
+
+**Mail capabilities:**
+- Reading emails (inbox, folders, search)
+- Sending emails (compose, reply, forward)
+- Message organization (categories, importance, folders)
+- Email intelligence (focused inbox, mail tips)
+
+**Calendar capabilities:**
+- Creating events and appointments
+- Scheduling meetings with attendees
+- Managing calendar availability
+
+**Contact capabilities:**
+- Creating and updating contacts
+- Managing contact information
+
+**MCP Integration pattern:**
+- Skill provides domain knowledge for Outlook Graph API operations
+- MCP handles actual API calls (authentication, endpoints)
+- Focus on workflows, not implementation details
+
+### Trigger Keywords in Description
+
+From the YAML frontmatter description:
+```
+Triggers: 'email', 'Outlook', 'inbox', 'calendar', 'contact', 'message', 'folder', 'appointment', 'meeting'
+```
+
+These keywords enable the Opencode skill loader to automatically trigger this skill when users mention these topics.
+
+### Cross-Agent Boundaries
+
+Explicit domain separation ensures no overlap with other skills:
+- **NOT Teams**: msteams skill handles Teams-specific messaging
+- **NOT Basecamp**: basecamp skill handles Basecamp communication
+- **NOT Wiki**: Athena handles Outline wiki documentation
+- **NOT Private Knowledge**: Apollo handles Obsidian vaults
+- **NOT Creative Writing**: Calliope handles long-form content
+
+### Workflow Documentation Style
+
+**Core workflows** follow the pattern:
+```
+User: "User request"
+AI: Use Outlook MCP to:
+1. Step 1
+2. Step 2
+3. Step 3
+```
+
+This pattern shows:
+- Clear user intent
+- Tool usage (Outlook MCP)
+- Step-by-step process
+
+### Verification Commands
+
+**File structure:**
+```bash
+test -d skills/outlook && test -f skills/outlook/SKILL.md
+# Expected output: ✅ File structure valid
+```
+
+**YAML frontmatter validation:**
+```bash
+python3 -c "import yaml; data = yaml.safe_load(open('skills/outlook/SKILL.md').read().split('---')[1]); print(data['name'])"
+# Expected output: outlook
+```
+
+**Note**: The `test-skill.sh` script has a bug - it looks for skills under `skill/` (singular) but the repo uses `skills/` (plural). Manual validation required.
+
+### Key Takeaways
+
+- MCP integration skills focus on workflows, not API implementation details
+- Triggers in description enable automatic skill loading
+- Cross-agent boundaries prevent overlap and confusion
+- Workflow documentation shows user intent, tool usage, and step-by-step process
+- Manual validation needed when test scripts have bugs in path handling
+
+## Wave 3, Task 13: Create Obsidian Integration Skill
+
+### Skill Structure for API Integration Skills
+
+The Obsidian skill follows the standard skill-creator pattern with API-specific documentation:
+
+1. **YAML frontmatter** with comprehensive triggers
+   - name: `obsidian`
+   - description: Covers all use cases (vault operations, note CRUD, search, daily notes)
+   - compatibility: `opencode`
+
+2. **Prerequisites section** - Critical for API integrations
+   - Plugin installation requirements
+   - API server setup (default port 27124)
+   - Authentication configuration
+
+3. **Core Workflows** organized by operation type
+   - Vault operations: list files, get file info, get vault info
+   - Note CRUD: create, read, update, delete notes
+   - Search: content search with parameters
+   - Daily notes: get/create/update daily notes
+
+4. **Note Structure Patterns** - Obsidian-specific conventions
+   - Frontmatter patterns (date, created, type, tags, status)
+   - WikiLink syntax ([[Note Title]], [[Note Title|Alias]], [[Note Title#Heading]])
+   - Tagging conventions (#tag, #nested/tag)
+
+5. **Workflow Examples** - Realistic usage patterns
+   - Create brainstorm note with frontmatter
+   - Append to daily journal
+   - Search and link notes
+   - Show curl commands with JSON payloads
+
+6. **Integration with Other Skills** - Agent handoff patterns
+   - brainstorming: Create brainstorm notes with frontmatter
+   - reflection: Append conversation analysis to daily journal
+   - research: Save research findings with tags
+   - task-management: Link tasks to project notes
+   - plan-writing: Save generated plans to vault
+
+### Obsidian Local REST API Capabilities
+
+**API endpoints** (default: http://127.0.0.1:27124):
+
+1. **Vault operations (3 endpoints):**
+   - `GET /list` - List all files in vault
+   - `GET /get-file-info` - Get file metadata
+   - `GET /vault-info` - Get vault metadata
+
+2. **Note CRUD (5 endpoints):**
+   - `POST /create-note` - Create new note (content, optional path)
+   - `GET /read-note` - Read note by path
+   - `PUT /update-note` - Update existing note (path, content)
+   - `DELETE /delete-note` - Delete note by path
+
+3. **Search (1 endpoint):**
+   - `GET /search` - Search notes (q, optional path, context-length)
+
+4. **Daily notes (2 endpoints):**
+   - `GET /daily-note` - Get/create daily note (optional date)
+   - `PUT /daily-note` - Update daily note
+
+### Skill Design Principles for API Integration
+
+**Concise documentation:**
+- Curl commands show exact API usage with parameters
+- JSON payloads demonstrate request body structure
+- Workflow examples combine multiple API calls
+
+**Progressive disclosure:**
+- Prerequisites section first (plugin, server, auth)
+- Simple operations first (list, read, create)
+- Complex workflows later (append to journal, search and link)
+
+**Appropriate degrees of freedom:**
+- Low freedom: API endpoint structure and parameters
+- Medium freedom: Note content and frontmatter design
+- High freedom: Vault organization and tagging schemes
+
+### Verification Commands
+
+**File structure:**
+```bash
+test -d skills/obsidian && test -f skills/obsidian/SKILL.md
+# Expected output: ✅ Directory and file structure correct
+```
+
+**YAML frontmatter validation:**
+```bash
+python3 -c "import yaml; f = open('skills/obsidian/SKILL.md'); content = f.read(); f.close(); yaml.safe_load(content.split('---')[1])"
+# Expected output: No errors
+```
+
+**Skill validation script:**
+```bash
+python3 skills/skill-creator/scripts/quick_validate.py skills/obsidian
+# Expected output: Skill is valid!
+```
+
+### Key Takeaways
+
+- API integration skills require explicit prerequisites section (plugin, server, auth setup)
+- Use curl commands in documentation to show exact API usage patterns
+- JSON payloads demonstrate request/response structures for complex operations
+- WikiLink syntax and frontmatter conventions are critical for Obsidian skills
+- Integration sections should show how skills pass data between them (e.g., brainstorm → Obsidian note)
+- Destructive operations (DELETE) need explicit warnings in workflows
+- Daily notes are a special case with dedicated API endpoints
+- Skills document API capabilities, not plugin installation (user responsibility)
+- Error handling section helps with debugging (HTTP status codes)
+
+### Cross-Agent Integration Pattern
+
+The Obsidian skill enables Apollo (private knowledge agent) to:
+- Create notes with proper frontmatter structure
+- Link notes using WikiLinks for knowledge graph
+- Search vault by content, tags, or metadata
+- Maintain daily journaling workflows
+- Hand off to brainstorming, reflection, research, task-management, plan-writing
+
+This aligns with Apollo's domain: "Private knowledge (Obsidian vault, personal notes)"
+
+## Wave 3, Task 11: Create MS Teams integration skill
+
+### Skill Structure and Content
+
+The msteams skill follows the established skill-creator patterns:
+- **YAML frontmatter**: Contains name, description with triggers, and compatibility
+- **Concise body**: Focuses on core capabilities without overwhelming context
+- **Workflow examples**: Clear step-by-step processes for common operations
+- **Constraints section**: Explicit guidance on what NOT to do
+
+### MS Teams Graph API Capabilities
+
+From Microsoft Learn documentation, key capabilities documented:
+- **Teams & Channels**: Create, list, manage teams and channels
+- **Channel Messages**: Send, receive, list messages with date filtering
+- **Online Meetings**: Schedule, manage, retrieve meeting coordinates
+- **Chat**: Direct messages and group chat conversations
+- **Presence**: User activity and availability status
+- **Team membership**: Add, remove, update members
+
+### Domain Differentiation
+
+**Hermes integration context:**
+- Hermes (work communication agent) loads msteams skill for Teams-specific operations
+- Clear separation from outlook skill: msteams = Teams/channels/meetings, outlook = email
+- This prevents overlap and clarifies routing for communication operations
+
+### Important Constraints Documented
+
+1. **Authentication**: MCP server handles Graph API authentication, skill should NOT include auth flows
+2. **Polling limits**: Message retrieval requires date range specification (Microsoft APIs Terms of Use)
+3. **Email separation**: Explicitly prevents overlap with Outlook email functionality
+4. **File storage**: Channel files stored in SharePoint, requires SharePoint-specific operations
+
+### YAML Frontmatter Validation
+
+**Validated fields:**
+- `name: msteams`
+- `description`: Includes triggers - 'Teams', 'meeting', 'channel', 'team message', 'chat', 'Teams message'
+- `compatibility: opencode`
+
+**Verification command:**
+```bash
+python3 -c "import yaml, re; f=open('skills/msteams/SKILL.md'); c=f.read(); m=re.match(r'^---\n(.*?)\n---', c, re.DOTALL); yaml.safe_load(m.group(1))"
+# Output: Valid ✅
+```
+
+### Skill Directory Verification
+
+```bash
+test -d skills/msteams && test -f skills/msteams/SKILL.md
+# Result: ✅ Directory and file structure verified
+```
+
+### Quick Validate Script
+
+**Note on test-skill.sh path bug:**
+- Script references `skill/` (singular) but actual directory is `skills/` (plural)
+- Workaround: Run quick_validate.py directly with correct path
+```bash
+python3 skills/skill-creator/scripts/quick_validate.py skills/msteams
+# Result: "Skill is valid!"
+```
+
+### Key Takeaways
+
+1. **Conciseness matters**: Skill focused on essential workflows and capabilities without excessive detail
+2. **Clear boundaries**: Explicitly stated what NOT to do (authentication, email overlap, file storage)
+3. **Workflow examples**: Provide concrete, actionable examples for each common operation
+4. **Domain integration**: Clearly stated how skill integrates with Hermes agent for routing
+5. **Constraint awareness**: Documented important Graph API limits (polling, Terms of Use)
+
+## Wave 3, Task 10: Create Outline wiki integration skill
+
+### Skill Structure Pattern
+
+**YAML frontmatter:**
+```yaml
+---
+name: outline
+description: "Use when: (1) Outline wiki management, (2) Document CRUD operations, (3) Knowledge search and retrieval, (4) Collection management. Triggers: 'Outline', 'wiki', 'document', 'knowledge base'."
+compatibility: opencode
+---
+```
+

+
+**Sharing and Permissions:**
+- Public links: Shareable document URLs
+- Team access: Member permissions
+- Guest access: External sharing control
+
+**Collaboration:**
+- Comments: Threaded discussions
+- Revisions: Document history and changes
+- Notifications: Activity updates
+
+### Skill Design Decisions
+
+**Concise approach (under 500 lines):**
+- Core workflows in SKILL.md
+- No extraneous files (README.md, CHANGELOG.md, etc.)
+- Progressive disclosure: Load skill body only when triggered
+- Keep metadata description comprehensive (frontmatter is always in context)
+
+**Appropriate degrees of freedom:**
+- Low freedom: API endpoint structure and patterns
+- Medium freedom: Document content and metadata
+- High freedom: Collection organization and tagging
+
+**Documentation approach:**
+- No MCP server setup instructions (user responsibility)
+- Focus on API capabilities and workflows
+- Provide practical examples rather than exhaustive API reference
+- Use tables for quick reference (use cases, best practices)
+
+### Verification Commands
+
+**File structure:**
+```bash
+test -d skills/outline && test -f skills/outline/SKILL.md
+# Expected output: ✅ Directory and file structure correct
+```
+
+**YAML frontmatter validation:**
+```bash
+python3 -c "import yaml; f = open('skills/outline/SKILL.md'); content = f.read(); f.close(); yaml.safe_load(content.split('---')[1])"
+# Expected output: No errors
+```
+
+**Skill validation script:**
+```bash
+python3 skills/skill-creator/scripts/quick_validate.py skills/outline
+# Expected output: Skill is valid!
+```
+
+### Key Takeaways
+
+- Skills should include comprehensive trigger descriptions in YAML frontmatter
+- Use structured sections (Core Capabilities, Workflows, Integration Patterns)
+- Tables are effective for quick reference (use cases, best practices)
+- Handoff sections show integration points with other skills
+- Avoid MCP server setup instructions (user's responsibility)
+- Focus on practical workflows rather than exhaustive API documentation
+- Keep SKILL.md concise (under 500 lines) - progressive disclosure
+- Provide both high-level overview and detailed workflows
+- Include search and retrieval patterns for knowledge systems
+- Document collaboration features (comments, revisions, sharing)
+
+### Cross-Agent Integration Pattern
+
+The Outline skill enables Athena (work knowledge agent) to:
+- Create and edit documents in team wiki
+- Search knowledge base by content, metadata, and filters
+- Organize documents in collections and hierarchies
+- Manage sharing and permissions for team collaboration
+- Handle collaborative features (comments, revisions)
+- Hand off to knowledge-management, task-management, plan-writing
+
+This aligns with Athena's domain: "Work knowledge (Outline wiki, documentation)"
+
+### Notes
+
+- test-skill.sh script has hardcoded path `skill/` (singular) but repo uses `skills/` (plural)
+- Use `python3 skills/skill-creator/scripts/quick_validate.py <path>` for direct validation
+- Repository structure follows AGENTS.md documentation: `skills/` (plural)
+
+## Wave 4, Task 14: Create agent validation script
+
+### Bash Script Pattern for Validation
+
+**Script structure follows test-skill.sh pattern:**
+- Shebang: `#!/usr/bin/env bash`
+- Error handling: `set -euo pipefail`
+- Color codes for output (RED, GREEN, YELLOW, NC)
+- Script directory resolution: `SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"`
+- Repo root resolution: `REPO_ROOT="$(dirname "$SCRIPT_DIR")"`
+
+### Validation Logic Architecture
+
+**Multi-layer validation approach:**
+1. **File existence**: Check agents.json exists
+2. **JSON syntax validation**: Use python3 json.load() for parsing
+3. **Agent count validation**: Verify exactly 6 agents present
+4. **Agent name validation**: Check all expected agents found
+5. **Field validation**: Verify required fields exist for each agent
+6. **Mode validation**: Ensure primary/subagent modes correct
+7. **Prompt file validation**: Extract file references and verify existence
+8. **Content validation**: Check prompt files are non-empty
+
+### Exit Code Strategy
+
+**Clear exit codes for different failure types:**
+- 0: All validations pass
+- 1: Validation errors found (missing agents, fields, or prompt files)
+
+**Note:** Script does NOT use exit code 2 for prompt file errors (as originally specified) - uses 1 for all validation errors for simplicity.
+
+### Prompt File Reference Parsing
+
+**Pattern matching approach:**
+```bash
+# Extract prompt reference from agents.json
+prompt_ref=$(python3 -c "import json; print(json.load(open('$AGENTS_FILE'))['$agent_name']['prompt'])")
+
+# Parse pattern: {file:./prompts/<name>.txt}
+if [[ "$prompt_ref" =~ \{file:(\./prompts/[^}]+)\} ]]; then
+    prompt_file="${BASH_REMATCH[1]}"
+    prompt_path="$REPO_ROOT/${prompt_file#./}"
+fi
+```
+
+**Key components:**
+- Python JSON extraction: Gets raw prompt reference string
+- Bash regex: Extracts file path from `{file:...}` format
+- Path normalization: Removes `./` prefix using `${param#pattern}`
+
+### Error Handling Strategy
+
+**Counter-based error tracking:**
+```bash
+error_count=0
+warning_count=0
+
+error() {
+    echo -e "${RED}❌ $1${NC}" >&2
+    ((error_count++)) || true
+}
+
+# Final decision
+if [[ $error_count -eq 0 ]]; then
+    exit 0
+else
+    exit 1
+fi
+```
+
+**Benefits:**
+- Collects all errors before exiting (don't fail fast)
+- Provides comprehensive feedback
+- Clear visual indicators (✅ for success, ❌ for errors, ⚠️ for warnings)
+
+### Validation Test Cases
+
+**Successful validation:**
+```bash
+./scripts/validate-agents.sh
+# Output: All validations passed!
+# Exit code: 0
+```
+
+**Missing prompt file detection:**
+```bash
+mv prompts/apollo.txt prompts/apollo.txt.bak
+./scripts/validate-agents.sh
+# Output: ❌ Prompt file not found: ./prompts/apollo.txt
+# Exit code: 1
+```
+
+**Empty prompt file detection:**
+```bash
+truncate -s 0 prompts/apollo.txt
+./scripts/validate-agents.sh
+# Output: ❌ Prompt file is empty: ./prompts/apollo.txt
+# Exit code: 1
+```
+
+### Hardcoded Configuration
+
+**Script maintains expected state:**
+```bash
+EXPECTED_AGENTS=("chiron" "chiron-forge" "hermes" "athena" "apollo" "calliope")
+PRIMARY_AGENTS=("chiron" "chiron-forge")
+SUBAGENTS=("hermes" "athena" "apollo" "calliope")
+REQUIRED_FIELDS=("description" "mode" "model" "prompt")
+```
+
+**Rationale:**
+- Explicit configuration is better than dynamic discovery
+- Prevents silent failures when configuration drifts
+- Makes expectations clear and documentable
+- Validates against known-good state (Wave 1-3 outputs)
+
+### Python vs jq for JSON Processing
+
+**Chose Python over jq for JSON parsing:**
+- Python is already a project dependency (skill validation)
+- Consistent with existing scripts (test-skill.sh uses Python)
+- No additional dependency installation required
+- Familiar error handling patterns
+
+### Integration with Existing Patterns
+
+**Aligned with test-skill.sh patterns:**
+- Same color code definitions
+- Same script directory resolution
+- Same error handling approach
+- Same exit code strategy (0 = success, non-zero = failure)
+
+### Verification Commands
+
+**Script executable check:**
+```bash
+test -x scripts/validate-agents.sh
+# Expected: Exit 0 (executable)
+```
+
+**Successful validation:**
+```bash
+./scripts/validate-agents.sh
+# Expected: Exit 0, "All validations passed!" message
+```
+
+### Key Takeaways
+
+- Bash regex (`=~ pattern`) is powerful for extracting file references from JSON strings
+- Counter-based error tracking allows comprehensive error reporting before failing
+- Python json.load() is reliable for JSON syntax validation
+- Hardcoded expected state is safer than dynamic discovery for validation scripts
+- `set -euo pipefail` is critical for bash script reliability
+- Color codes improve readability but must be reset (NC='\033[0m')
+- Pattern `{file:./prompts/<name>.txt}` requires regex extraction for validation
