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

> to (email address, optional if unknown), subject (optional), content or intent (what to say, can be rough notes), threadId (optional, for replies)

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 External Actions Guide]: Read the documentation in: `skills/sauna/[skill_id]/references/sauna.actions.external.md` (Preview UI pattern for external actions)

2. [Read Email Drafting Guidelines]: Read the documentation in: `skills/sauna/[skill_id]/references/gmail.draft.rules.md` (Guidelines for drafting emails)

3. [Read User Analysis Results]: Discover relevant information in the user's filesystem at `documents/user/analysis/*.md`. (User's gmail writing style to match (file: writing-style.md))

4. [Read Domain Preferences]: Discover relevant information in the user's filesystem at `documents/preferences/[domain].md`. (Check for saved email preferences and past corrections (domain: email))

5. Check what's already provided in requirements. Only ask for what's missing:
- to: recipient email (skip if already known)
- subject: what it's about (skip if already known)
- content: what to say (skip if already known)

If all are provided, proceed directly to composing.


6. Compose the email body matching the user's gmail writing style from `documents/user/analysis/*.md` (file: writing-style.md).

Write a preview draft with _action frontmatter:

---
_action:
  label: "Save draft"
  prompt: "Create this Gmail draft using the content below. Format body as HTML."
  isComplete: false
---

**To:** [recipient]
**Subject:** [subject]

[body]

Sauna displays this as a preview card with a "Save draft" button.
User can edit the content, then click to save.


7. [Gather Arguments: Create Gmail Draft] The next step has the following requirements for arguments, do not proceed until you have all the required information:
- `to`: {{to}}
- `subject`: {{subject}}
- `body`: {{body}}
- `threadId`: {{threadId}}
- `outputPath` (default: "session/draft-result.json"): session/draft-result.json
- `htmlBody` - Optional HTML email body (creates multipart message)
- `inReplyTo` - Message-ID header from original message (for proper reply threading)
- `cc` - CC recipients (comma-separated)
- `bcc` - BCC recipients (comma-separated)

8. [Run Code: Create Gmail Draft]: Call `run_script` with:

```json
{
  "file": {
    "path": https://sk.ills.app/code/gmail.draft.create/preview,
    "args": [
      "to",
      "subject",
      "body",
      "threadId",
      "outputPath",
      "htmlBody",
      "inReplyTo",
      "cc",
      "bcc"
    ]
  },
  "packages": null
}
```

9. Check the result. If successful:
"Draft saved. Open Gmail to review and send when ready."

If failed, explain the error.
