Find available time slots in a calendar and schedule meetings while respecting constraints.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Calendar Scheduling Logic Skill
## Overview
This skill covers scheduling algorithms to find available time slots in a calendar, handle time conflicts, prioritize blue-colored flexible blocks, and match meeting requests with available time windows.
## Key Concepts
### Calendar Representation
```python
# Event representation
event = {
'name': 'Weekly Group Meeting',
'start_hour': 10,
'start_minute': 0,
'end_hour': 11,
'end_minute': 0,
'color': 'red', # 'red', 'blue', 'yellow', 'gray'
'is_flexible': True/False # Only blue is True
}
# 15-minute interval representation
# 9:00am = index 0, 9:15am = index 1, etc.
```
### Constraint Types
1. **User Availability Window**: Person only available during specific hours
2. **Date Constraint**: Meeting must be on specific date
3. **Duration Requirement**: Meeting needs exact duration
4. **Block Overriding**: Blue blocks can be overridden for higher priority meetings
## Code Examples
### Time Conversion to Minutes
```python
def time_to_minutes(hour, minute):
"""Convert hour:minute to total minutes since midnight"""
return hour * 60 + minute
def minutes_to_time(minutes):

How to install
mdr add cxcscmu/skilllearnbench/calendar-scheduling-logic@sha256:97c1d77af00250afThe line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
