+# Drafts Cowork Inbox
+
+Process the "cowork" tagged items in Drafts — your capture-to-action pipeline.
+
+## When to Use
+
+Use this skill at the start of a session or whenever you want to process items you've captured throughout the day via Drafts on iPhone, Apple Watch, or Mac.
+
+## Prerequisites
+
+- Drafts MCP connector must be set up
+- Items to process should be tagged "cowork" in the Drafts app
+
+## Instructions
+
+1. Read all drafts tagged "cowork" using the Drafts MCP tools.
+2. Present a numbered list of items with a brief preview of each.
+3. For each item, classify it and take the appropriate action:
+
+| Type | Action |
+|------|--------|
+| **Task or to-do** | Create a note or reminder in the workspace. Flag if urgent. |
+| **Content idea** | Create a content idea note with a title and brief description. |
+| **Research request** | Do the research and report findings. |
+| **Quick instruction** | Execute the instruction (file a note, move a file, look something up). |
+| **Question** | Answer the question. |
+| **Unclear** | Ask for clarification before acting. |
+
+4. After processing each item, archive the draft.
+5. Report what was done: "[N] items processed. [Brief summary of actions taken.]"
+
+## Rules
+
+- Process items one at a time. Don't batch everything silently.
+- When an item is ambiguous, ask rather than guess.
+- Archive each draft only after it's been fully processed.
+- If an item requires a tool you don't have access to, note it and move on.
