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

> Time span and milestones, optional icons per milestone

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 Business Visual Prompt Templates]: Read the documentation in: `skills/sauna/[skill_id]/references/media.visual.prompts.md` (Get timeline template)

2. Ask for timeline details:
- What time span? (e.g., 2020-2025, Q1-Q4)
- What milestones to show? (4-8 typical)
- Include dates/years or just sequence?
- Color progression? (Default: past=blue to future=green)


3. Construct the prompt using the Timeline template:
1. Set time span
2. List milestones with years/quarters
3. Suggest icons for each milestone type
4. Set color progression


4. [Gather Requirements for Generate Image] The next step has the following requirements: "Text description of the image. Optional: aspect ratio (1:1, 16:9, 9:16, 4:3), style (photorealistic, illustration, painting), mood/lighting preferences.". Search the user's data for this information or ask them directly if needed. Do not proceed until you have this information.

5. [Execute Generate Image Task]: Spawn a subagent and provide it with the requirements gathered above and instructions to read `skills/sauna/[skill_id]/references/recipes/media.image.generate.md` for its task list

6. Show the generated timeline. Offer to adjust milestones, dates, or style.
