+# deploy
+
+## Trigger
+Use this skill when approved rules are ready to be implemented in Gmail, the user says
+"deploy the rules", "create the filters", "let's push this batch", or a specific rule
+set has been approved through the `import` review process.
+
+## Purpose
+Implements approved rules from the Tracker into Gmail. This means:
+- Gmail filters via Google Workspace MCP (Claude executes directly)
+- Apps Script deployment via step-by-step user walkthrough (Claude guides, user executes)
+
+## Non-Technical User Standard
+This skill must never assume the user knows what a Gmail filter is, what Apps Script is,
+or how to navigate Google's admin interfaces. Every instruction must be written in plain
+English with numbered steps, screenshots described in words, and explicit "click X, then Y"
+guidance.
+
+## Bulk Operation Rule (North Star)
+For operations involving hundreds or thousands of existing emails (mass label changes,
+backfills, restructuring), Claude must:
+1. Recommend the lowest-cost path first (Gmail UI, a pre-built script, or a task order
+   to a lower-cost agent)
+2. Guide the user through that path OR produce a task order that handles it
+3. Never burn Claude tokens on mechanical, row-by-row email operations
