Support

Start new investigation:

• /support zendesk 40875
• /support github 12345
• /support z 40875 (shorthand)
• /support gh 12345 (shorthand)

Your Task

Step 1: Parse and Validate Arguments

Extract from user input:

• find_mode = true if first argument is "find"
• ticket_type = zendesk (or z) / github (or gh)
• ticket_number = numeric ticket ID

Normalize shorthands:

• z → zendesk
• gh → github

If either ticket_type or ticket_number is missing, ask the user for them. Do not proceed without both.

Step 2: Locate the Notes Directory

Run the helper script to find an existing ticket or get the path for a new one. Never construct paths manually — the script handles week calculations, backwards search through previous weeks, and directory validation.

result=$(~/.claude/skills/support/scripts/support-find-ticket.sh {ticket_type} {ticket_number})
status=$(echo "$result" | cut -f1)
notes_dir=$(echo "$result" | cut -f2)

If find_mode is true, present results and stop — do not create any directories or files:

• status is "found": Display "Found existing support notes for {ticket_type} #{ticket_number}", show the directory and $notes_dir/notes.md paths, read and summarize the first ~30 lines of the notes file, and offer to continue the investigation.
• status is "new": Display "No existing notes found for {ticket_type} #{ticket_number}", show where notes would be created, and suggest running /support {ticket_type} {ticket_number} to start a new investigation.

If find_mode is false, create the directory if needed and proceed:

if [[ "$status" == "found" ]]; then
    echo "Found existing ticket at: $notes_dir"
else
    echo "Creating new ticket at: $notes_dir"
    mkdir -p "$notes_dir"
fi

Step 3: Initialize and Confirm

Create notes.md in $notes_dir using the template from templates/investigation-notes.md. Construct the ticket URL as:

• Zendesk: https://posthoghelp.zendesk.com/agent/tickets/{number}
• GitHub: https://github.com/PostHog/posthog/issues/{number}

Tell the user:

1. Where notes are being stored (full path)
2. The ticket URL for reference
3. Ask them to describe the customer's issue

Then continue the investigation using the support agent guidelines (systematic debugging, documentation, etc.).

Boundary: /support vs note-taker

If you discover something during support that should be permanent technical docs, spawn note-taker separately to capture it in ~/dev/ai/notes/.
