Claude Code Essentials

Sends a fixed, pre-written email about CLAUDE.md files, the memory file Claude Code reads every session. Three rules: write it like day one onboarding, keep it short and specific, and layer it so it grows from your own corrections.

Assets

• templates/essentials.html - branded HTML body, matches the email skill house style
• templates/essentials.txt - plain text alternative (required by Resend, and better for deliverability)

Both use a single {first_name} placeholder.

Send Config

• From: Tyler Reed <hello@tylerai.dev> (tylerai.dev is the verified Resend domain)
• Reply-to: hello@tylerai.dev
• Tag: category: claude-code-essentials
• Send with the mcp__plugin_resend_resend__send-email tool. Do not shell out to the email skill's scripts, those log into the Skool database and this email is not a Skool blast.

What to Do

1. Get the recipient. Use the email passed as an argument. If none was given, ask for it with AskUserQuestion. Multiple recipients are fine, pass them all in the to array.
2. Get the first name. Use --name if given. If not, derive it from the email local part when it is obviously a name, otherwise fall back to there so the greeting reads "Hey there,".
3. Fill the templates. Read both files, replace every {first_name}. Never send a body with an unreplaced {first_name} in it, check before sending.
4. Show and confirm. Print the subject and the plain text body to the user and get explicit approval before sending. Never auto-send.
5. Send.
   • subject: The 3 rules of a great CLAUDE.md
   • from: Tyler Reed <hello@tylerai.dev>
   • replyTo: ["hello@tylerai.dev"]
   • html: filled essentials.html
   • text: filled essentials.txt
   • tags: [{"name": "category", "value": "claude-code-essentials"}]
   • idempotencyKey: cc-essentials-<recipient>-<yyyy-mm-dd> so a retry does not double send
6. Report the returned email ID.

Editing the Content

The three rules are the whole point of this skill, do not silently rewrite them. If the user asks for different content, edit both essentials.html and essentials.txt together so the two bodies stay in sync, and update the subject line above to match.

Rules

• No em dashes in any email content
• Always confirm before sending
• Keep the HTML and text bodies saying the same thing
