scheduling-engine

scheduling-engine is a skill for Claude Code, Codex from cxcscmu/SkillLearnBench. It costs 17 tokens per session (337 once invoked), scanned A, original, MIT.

A scheduling algorithm that finds the earliest meeting time fitting duration, time-window, and existing-appointment constraints. It can treat low-priority calendar blocks as available when needed.

In plain words
What is it for?
It helps propose meeting times from schedules and requests, while considering fixed appointments and flexible blocks.
Why use it?
It removes the manual work of comparing calendars and checking overlapping appointments.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scheduling-engine scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Scheduling Engine

This skill manages the logic for finding the earliest possible time slot for a meeting, accounting for both hard and soft (low-priority) conflicts.

Key Logic

  • Represent the day's schedule as a list of occupied and flexible (low-priority) blocks.
  • Filter the schedule based on meeting constraints (start time, end time, duration).
  • Consider 'blue' blocks as open slots that can be overwritten.

Example Python logic for overlapping checks

from datetime import datetime, timedelta

def find_earliest_slot(requests, schedule, blue_blocks):
    """
    requests: List of (duration_hrs, constraint_start, constraint_end)
    schedule: List of occupied (start, end)
    blue_blocks: List of low-priority (start, end)
    """
    # 1. Open up blue blocks
    # Effective occupied schedule: schedule minus any block in blue_blocks.
    
    # 2. Iterate through candidate start times (e.g., every 15 mins)
    # Check if a candidate start_time + duration fits within constraints.
    # Check if candidate window (start, end) overlaps with any occupied block.

Important Considerations

  • Handle multiple requests (though the task is to propose a meeting for all requests, typically it means finding a slot for each one independently while trying to fit all if possible - although the workflow says "propose a meeting time for all requests").
  • Ensure that the earliest compatible time is selected.
  • Date/Time formatting for output is critical.

scheduling-engine is a skill published in the GitHub repository cxcscmu/SkillLearnBench (83 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 337 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
