## Description

If you have a routine that repeats but isn't a simple every Monday schedule, you need a way to map it out without doing the math yourself. This MCP handles the logic of variable-length cycles. You give it a starting point and a list of steps, and it figures out where you are in that sequence at any point in time. It takes the guesswork out of things like Is today a treatment day or a rest day? or Which phase of the maintenance loop are we in right now? It's built for people who need precision in recurring tasks. When you find it in the Vinkius catalog, you'll see how it handles the heavy lifting of temporal calculations. Instead of manually checking a calendar or trying to remember if you skipped a step last week, your agent just looks at the date and tells you exactly what's next. It turns a messy, repeating list of actions into a predictable timeline that your agent can navigate for you. Whether you are tracking a 10-day medical treatment plan, a complex multi-step skincare regimen, or a recurring industrial maintenance loop, this tool ensures you never lose your place. It handles the tedious counting and date math, providing a reliable source of truth for your repeating workflows.

## Tools

### analyze_cycle_composition
Get a statistical breakdown of the total cycle length and how often specific steps occur. This helps you understand the frequency of your routine.

### find_next_occurrence
Find the very next date a specific step in your sequence will happen. This is useful for jumping ahead in a schedule.

### get_schedule_window
Generate a full chronological list of every step and date within a chosen time range. Use this for long-term planning.

### get_step_for_date
Identify the exact task name scheduled for any specific target date you provide. This gives you an immediate answer for a specific day.

## Capabilities

### Identify the specific task for a future date
Your agent tells you exactly which step of a repeating sequence falls on a date you provide.

### Forecast a full list of steps over a date range
Get a chronological list of every action and its corresponding date for a specific week or month.

### Locate the next time a specific event happens
Find the very next date a specific task in your cycle will appear in the future.

### Calculate the total length of a repeating sequence
Get a statistical overview of how long your cycle is and how often specific steps repeat.

### Determine the frequency of specific steps
See how often a specific action occurs within your defined repeating loop.

## Use Cases

### Skincare Routine Planning
A user wants to know if they should use a chemical exfoliant today based on a 3-day Active, Active, Rest cycle.

### Medication Treatment Plans

## Benefits

- Stop guessing your next step. Use get_step_for_date to know exactly what your routine requires today without checking a manual.
- See your future clearly. Use get_schedule_window to generate a full timeline of upcoming tasks for any date range.
- Never miss a specific treatment. Use find_next_occurrence to jump ahead and see when a specific event will happen next.
- Understand your routine's structure. Use analyze_cycle_composition to see the statistical breakdown of your repeating steps.
- Automate complex scheduling. Let your agent handle the math of variable-length cycles so you don't have to track dates manually.

## How It Works

The bottom line is that it turns a repeating list of actions into a searchable timeline.

1. Define your repeating sequence and an anchor start date.
2. Ask your agent to check a specific date or a range of dates.
3. Get a clear list of tasks or a single resolved step name.

## Frequently Asked Questions

**What is Cycle Day Resolver for?**
It helps you manage any repeating sequence of tasks where the order is fixed but the timing varies. It's perfect for things like skincare, medication, or industrial maintenance loops.

**Can I use it for skincare routines?**
Yes, it's a great fit for complex skincare. If you have a sequence like Active, Rest, Active, it will tell you exactly which step to perform on any given date.

**How does it handle variable-length cycles?**
You provide the list of steps and a start date. The MCP calculates the position in the sequence for any future date automatically.

**Can it forecast my schedule?**
Yes, you can ask your agent to show you every task for a specific week or month, and it will generate a full chronological list.

**What happens if I miss a day?**
Since it's based on a start date and a sequence, it keeps the timeline consistent. You can ask it to find the next occurrence of a specific task to get back on track.

**Is this different from a calendar?**
Yes. A calendar holds fixed events. This tool calculates steps based on a repeating loop, making it much more powerful for sequential tasks.

**How does the cycle resolution logic work?**
The engine calculates the number of days elapsed between your anchor start date and the target date, then finds the remainder when divided by the total cycle length to identify the correct step.

**Can I use this for skincare routines?**
Yes, you can provide a cycle array like ['Retinol', 'Exfoliant', 'Recovery'] and an anchor date to determine exactly which product to use on any future morning.

**What happens if the target date is before the start date?**
The `get_step_for_date` tool will return an error stating that the target date must be equal to or later than the anchor date.
