3. Network access: Requires internet access to Microsoft Graph API endpoints
4. Microsoft Account: Personal Microsoft account (Hotmail, Outlook.com) or work/school account
5. Authentication: First-time use requires OAuth2 login via browser. See Authentication section
   • Token cache: ~/.mstodo_token_cache.json (persists across sessions, auto-refreshed)

Installation & Setup

First-Time Setup

Before using this skill for the first time, dependencies must be installed:

# Navigate to skill directory
cd <path-to-ms-todo-oauth>

# Create a venv in the project (creates '.venv' folder)
python3 -m venv .venv
# Activate the venv choose based on platforms:
#- Bash/Zsh: 
source .venv/bin/activate
# - Fish: 
source .venv/bin/activate.fish
#  - Windows (PowerShell):
.venv\Scripts\Activate.ps1

pip install --upgrade pip
pip install -r requirements.txt

# Alternative (global python env, not recommended):
# pip install -r requirements.txt

Dependencies:

• msal (Microsoft Authentication Library) - Official Microsoft OAuth library
• requests - HTTP client for API calls
• Specified in requirements.txt

Environment Verification

After installation, verify the setup:

# If using native venv (activate as above):
python3 scripts/ms-todo-oauth.py --help

# Expected: Command help text should be displayed

Troubleshooting:

• If Python not found, install Python 3.9 or higher from https://python.org

Testing (Optional but Recommended)

Verify all functionality works correctly:

# Run comprehensive automated test suite (29 tests)
python3 test_ms_todo_oauth.py

# Expected: All tests pass (100% pass rate)

See Testing section for details.

Security Notes

• Uses official Microsoft Graph API via Microsoft's msal library
• All code is plain Python (.py files), readable and auditable
• Tokens stored locally in ~/.mstodo_token_cache.json
• All API calls go directly to Microsoft endpoints (graph.microsoft.com)
• OAuth2 standard authentication flow
• No third-party services involved

Command Reference

All commands follow this pattern:

python3 scripts/ms-todo-oauth.py [GLOBAL_OPTIONS] <command> [COMMAND_OPTIONS]

Global Options

Option	Description
-v, --verbose	Show detailed information (IDs, dates, notes).Must be placed BEFORE the subcommand.
--debug	Enable debug mode to display API requests and responses. Useful for troubleshooting.Must be placed BEFORE the subcommand.
--reauth	Force re-authentication by clearing the token cache and starting fresh login

⚠️ Common mistake: Global options MUST come before the subcommand.

• ✅ python3 scripts/ms-todo-oauth.py -v lists
• ✅ python3 scripts/ms-todo-oauth.py --debug add "Task"
• ❌ python3 scripts/ms-todo-oauth.py lists -v

---

Authentication

Authentication uses OAuth2 authorization code flow, designed for both interactive and automated environments.

login get — Get OAuth2 authorization URL

python3 scripts/ms-todo-oauth.py login get

Output example:

======================================================================
🔐 OAuth2 Authorization Required
======================================================================

Please visit the following URL to authorize the application:

  https://login.microsoftonline.com/consumers/oauth2/v2.0/authorize?...

After authorization, you will be redirected to a callback URL.
Copy the 'code' parameter from the callback URL and run:

  ms-todo-oauth.py login verify <authorization_code>

======================================================================

What to do:

1. Open the provided URL in your browser
2. Sign in with your Microsoft account
3. Grant permissions when prompted
4. You'll be redirected to a URL like: http://localhost:8000/callback?code=M.R3_BAY.abc123...
5. Copy the entire code after code= (usually a long string starting with M.R3_BAY.)

Agent behavior: Present the URL to the user and explain they need to:

1. Visit the URL
2. Complete the login
3. Copy the authorization code from the callback URL
4. Provide it to you

login verify — Complete login with authorization code

python3 scripts/ms-todo-oauth.py login verify <authorization_code>

Example:

python3 scripts/ms-todo-oauth.py login verify "M.R3_BAY.abc123def456..."

Output on success:

✓ Authentication successful!
✓ Login information saved, you will be logged in automatically next time.

Output on failure:

❌ Token acquisition failed
Error: invalid_grant
Description: AADSTS54005: OAuth2 Authorization code was already redeemed...

Exit code: 0 on success, 1 on failure.

Important notes:

• Each authorization code can only be used ONCE
• If verification fails, you need to run login get again to get a new code
• Once successfully logged in, the token is cached and you won't need to login again unless:
  • You run logout
  • You run --reauth
  • The token expires and cannot be auto-refreshed

logout — Clear saved login

python3 scripts/ms-todo-oauth.py logout

Output: ✓ Login information cleared

Only use when the user explicitly asks to switch accounts or clear login data. Under normal circumstances, the token is cached and login is automatic.

---

Agent Usage Guidelines

Critical Rules

1. Working directory: Always cd to the directory containing this SKILL.md before running commands.

2. Dependency installation: Before first use or when encountering import errors, ensure all dependencies are installed.

3. Check authentication first: Before any operation, verify authentication status:

   python3 scripts/ms-todo-oauth.py lists
   

   If this returns "Not logged in" error (exit code 1), initiate the login flow.

4. Task list organization: When adding tasks:

   • First, run lists to see available task lists
   • If user doesn't specify a list, tasks will be added to their default list (usually "Tasks" or "任务")
   • Intelligently categorize tasks into appropriate lists:
     • Work tasks → "Work" list
     • Personal errands → "Personal" or default list
     • Shopping → "Shopping" list
     • Project-specific → Use project name as list
   • Lists will be auto-created if they don't exist
   • Support Chinese list names and Unicode characters

5. Destructive operations: For delete and delete-list:

   • These commands prompt for confirmation by default (blocking behavior)
   • Use -y flag ONLY when:
     • User has explicitly requested to delete without confirmation
     • The deletion intent is unambiguous and confirmed through conversation
   • When in doubt, ask the user for confirmation instead of using -y
   • These operations return exit code 1 on failure (resource not found)

6. Global option placement: -v, --debug, and --reauth must come BEFORE the subcommand:

   • ✅ python3 scripts/ms-todo-oauth.py -v lists
   • ❌ python3 scripts/ms-todo-oauth.py lists -v

7. Login flow:

   • Do NOT call login verify until user confirms they've completed browser authentication
   • Each authorization code can only be used once
   • If verify fails, you must run login get again for a new code

8. Error handling:

   • Check exit codes: 0 = success, 1 = failure, 2 = invalid arguments
   • Parse error messages to provide helpful guidance
   • Use --debug flag when troubleshooting API issues

Recommended Workflow for Agents

Step 1: Setup and Authentication Check
---------------------------------------
cd <skill_directory>

python3 scripts/ms-todo-oauth.py lists          # Test auth & see available lists

If exit code is 1 and output contains "Not logged in":
  a. python3 scripts/ms-todo-oauth.py login get
  b. Present URL to user
  c. Explain: "Visit this URL, login, and copy the 'code' parameter from callback URL"
  d. Wait for user to provide authorization code
  e. python3 scripts/ms-todo-oauth.py login verify "<code>"
  f. Verify success (exit code 0)

Step 2: Task Analysis and List Selection
-----------------------------------------
When user requests to add task(s):
  a. Analyze task context from user's description
  b. Review available lists (from Step 1 output)
  c. Choose appropriate list or use default:
     - Work-related → "Work"
     - Personal errands → "Personal" or default
     - Shopping items → "Shopping"
     - Project-specific → "<ProjectName>"
  d. If list doesn't exist, it will be auto-created

Step 3: Execute Operation
--------------------------
Add task with appropriate options:
  python3 scripts/ms-todo-oauth.py add "Task Title" \
    -l "Work" \
    -p high \
    -d 3 \
    -r 2h \
    -D "Detailed description" \
    -t "tag1,tag2"

Step 4: Verify and Report
--------------------------
Check exit code:
  - 0: Success → Confirm to user
  - 1: Failure → Parse error, provide guidance
  - 2: Invalid args → Fix command syntax

Optionally verify:
  python3 scripts/ms-todo-oauth.py tasks "<list>"  # Show updated list

Task Title Matching Rules

• Exact match required: complete, delete commands
• Partial/fuzzy match supported: detail, search commands
• Case-insensitive: All search operations
• Best practice: Use search first to find exact title, then use it in subsequent commands

Example workflow:

# Find task with fuzzy search
python3 scripts/ms-todo-oauth.py search "report"
# Output shows: "Complete Q1 Report"

# Use exact title from search results
python3 scripts/ms-todo-oauth.py complete "Complete Q1 Report" -l "Work"

Default List Behavior

• When -l is not specified, operations use the Microsoft To Do default list
• The default list is typically named "Tasks" (English) or "任务" (Chinese)
• To target a specific list, always provide -l "<ListName>"

Example Task Categorization

User request: "Add these tasks: buy milk, finish report, call dentist"

Agent approach:

# First check available lists
python3 scripts/ms-todo-oauth.py lists

# Categorize intelligently:
python3 scripts/ms-todo-oauth.py add "Buy milk" -l "Shopping"
python3 scripts/ms-todo-oauth.py add "Finish report" -l "Work" -p high -d 2
python3 scripts/ms-todo-oauth.py add "Call dentist" -l "Personal"
# Or use default list if no specific context: add "Call dentist"

Troubleshooting

Authentication Issues

Problem: ❌ Not logged in

• Solution: Run login get, complete browser flow, then login verify <code>

Problem: ❌ Token acquisition failed: invalid_grant

• Cause: Authorization code already used or expired
• Solution: Run login get again to get a fresh code

Problem: Login worked but now getting "Not logged in" again

• Cause: Token expired and auto-refresh failed
• Solution: Run --reauth to force fresh login:

  python3 scripts/ms-todo-oauth.py --reauth lists
  

Import/Dependency Issues

Problem: ModuleNotFoundError: No module named 'msal'

• Solution: Install dependencies: pip install -r requirements.txt

API/Network Issues

Problem: Connection timeout or network errors

• Check: Internet connection
• Check: Can you access https://graph.microsoft.com in browser?
• Try: Using --debug flag to see full API request/response

Problem: Unexpected API errors

• Try: Re-authenticate: python3 scripts/ms-todo-oauth.py --reauth lists
• Try: Debug mode: python3 scripts/ms-todo-oauth.py --debug <command>

Task/List Not Found

Problem: ❌ Task not found: <title>

• Solution: Use search to find exact title
• Note: complete and delete require exact title match

Problem: ❌ List not found: <name>

• Solution: Run lists to see exact list names
• Note: List names are case-sensitive

Test Failures

Problem: Tests failing with datetime errors

• Solution: Ensure you've applied all v1.1.0 fixes
• Check: Verify _parse_ms_datetime() helper function exists

Problem: Tests failing with "Not logged in"

• Solution: Authenticate before running tests:

  python3 scripts/ms-todo-oauth.py login get
  # Complete browser flow
  python3 scripts/ms-todo-oauth.py login verify <code>
  # Then run tests
  python3 test_ms_todo_oauth.py
