To run this task you must have the following required information:

> Time window to analyze (e.g., 'Saturday', 'until Thursday 6pm', 'tomorrow 2-6pm').

If you don't have all of this information, exit here and respond asking for any extra information you require, and instructions to run this task again with ALL required information.

You MUST use a todo list to complete these steps in order. Never move on to one step if you haven't completed the previous step. If you have multiple CONSECUTIVE read steps in a row, read them all at once (in parallel). Otherwise, do not read a file until you reach that step.

Add all steps to your todo list now and begin executing.

## Steps

1. [Read Calendar Blocking Guide]: Read the documentation in: `skills/sauna/[skill_id]/references/calendar.block.guide.md` (Meeting classification categories)

2. [Read Time Expressions Guide]: Read the documentation in: `skills/sauna/[skill_id]/references/world.time.expressions.md` (How to interpret flexible time expressions)

3. Determine WHICH DAY(S) to check—don't parse exact times yet, just get a date range for the fetch.
Examples: "flight delayed" → today/tomorrow, "until Thursday" → today through Thursday.
Check `documents/user/services/*.md` for timezone. Convert to YYYY-MM-DD.


4. [Gather Arguments: Fetch Calendar Events] The next step has the following requirements for arguments, do not proceed until you have all the required information:
- `startDate`: Start date in YYYY-MM-DD format
- `endDate`: End date in YYYY-MM-DD format

5. [Run Code: Fetch Calendar Events]: Call `run_script` with:

```json
{
  "file": {
    "path": https://sk.ills.app/code/calendar.google.events/preview,
    "args": [
      "startDate",
      "endDate"
    ]
  },
  "packages": null
}
```

6. **Analyze calendar to infer times:**
- If user mentioned delay (flight/train delayed): find the travel event, add delay to get new arrival
- Otherwise: find first REAL meeting (skip focus/OOO/reminders) as arrival time
- If can't find relevant event: "I don't see [flight/etc] on your calendar—when do you land?"

**Classify events:** Skip (focus/OOO/reminders) vs action needed (1:1s, team, external).

**Present:** "Your [flight] lands at [time]. Blocking until then affects: [summary].
Block until [time] and handle notifications?"

If yes → run `skills/sauna/[skill_id]/references/recipes/calendar.block.handle.md`. If no → confirm no action.
