The Channel Guard

Context

1. Check for .agents/product-context.md. If missing, ask the user to run /gtm:product-context first. If the user prefers to proceed without it, ask for the minimum required info inline: brand voice summary, ICP, and primary color.
2. Read references/sms-push-compliance.md for regulatory requirements, character limits, and opt-out formatting.

Inputs

1. Ask: "SMS, push, or both? What is the campaign goal?"
2. Ask: "Single message or sequence? If sequence, how many messages and over what timeframe?"
3. Ask: "What regions are you sending to? (affects compliance requirements)"

Process

1. Read .agents/product-context.md to pull brand voice, ICP, and design preferences.
2. Design message copy within channel limits:
   • SMS: Refer to the character encoding rules in the reference: 160 characters for GSM-7, but a single emoji switches to Unicode encoding (70 characters per segment). Calculate effective character budget after opt-out text. Include opt-out language (e.g., "Reply STOP to unsubscribe"). Use URL shortener placeholder for links.
   • Push: Title: 50 characters max. Body: 150 characters max. Specify deep link destination.
3. Set timing for each message:
   • Use the optimal send time windows from the reference file.
   • Minimum delay between messages in a sequence
4. Set frequency caps: Use the frequency caps from the reference file as defaults.
5. Include compliance elements: Include the relevant compliance requirements from the reference file based on the user's sending regions.
   • Push: permission status check before send, graceful fallback if denied
6. For push: specify deep link target (screen, URL, or in-app action).
7. For sequences: design timing logic between messages. Include delays, conditions for next message (e.g., "send message 2 only if no app open within 48 hours"), and escalation path.
8. Recommend an A/B test variant (copy, timing, or CTA) with hypothesis and success metric.

Output

1. Before delivering, verify:

• SMS character math is correct for the actual message: 160 characters for GSM-7, or 70 per segment if any emoji forces Unicode encoding, with the opt-out text counted against the budget
• Push title is 50 characters or under and body is 150 characters or under
• Compliance elements match the regions the user named, not a generic default
• Frequency caps and suppression rules are stated, not left implicit

If any check fails, fix it before delivering.

1. Deliver the campaign spec:

• Campaign Summary: Channel, goal, target segment, total messages, duration, expected volume
• Messages Table: Columns: # | Channel | Timing | Copy | Chars | Deep Link/URL | Condition (for sequences)
• Message Preview: ASCII mockup showing how each SMS or push notification appears on-device (SMS bubble or notification card format)
• Compliance Checklist: Region-specific requirements, opt-out language with exact text, quiet hours with timezone handling, permission checks
• Guardrails: Frequency caps (per-campaign and cross-channel), suppression rules, expiry rules, fallback behavior if push permission denied
• Personalization: Liquid or merge tag placeholders used, with fallback defaults for each
• A/B Test: Recommended variant, hypothesis, primary metric, minimum sample size
