Verification
Before marking work as done, you MUST:
- 4-week content calendar completed with specific content mapped per day
- Platform posting schedule includes optimal times and frequencies
- Batching schedule is realistic (time estimates per content type)
- Content mix follows 70/20/10 rule (planned/topical/promotional)
- Calendar maps back to content pillars from content architecture
- All calendar artifacts stored in
docs/marketing/calendar/
Evidence required: Complete calendar document with all slots filled and pillar mappings.
Failure Modes
| Symptom | Likely Cause | Fix |
|---|---|---|
| Calendar is unrealistically ambitious | Too many posts/day for available resources | Scale back to sustainable frequency, quality over quantity |
| Content gaps in calendar | Missing content architecture | Request content-architect output before building calendar |
| No variety in content types | Over-reliance on one format | Mix formats: threads, carousels, long-form, video, polls |
| Calendar doesn't account for creation time | Batching schedule missing | Add creation days before publishing days |
| Seasonal opportunities missed | No forward-looking research | Research industry events, holidays, trending topics 4-8 weeks ahead |
Never
- Never schedule content without confirming production capacity
- Never ignore platform-specific optimal posting times
- Never create a calendar without buffer for reactive/trending content
Escalation
- If content architecture is missing → request content-architect analysis first
- If calendar exceeds user's capacity → present scaled-down options with trade-offs
- If platform strategy unclear → request audience-architect for platform-persona mapping
Communication
When working on a team, report:
- Calendar created with total content piece count
- Production timeline with batching schedule
- Distribution plan for cross-platform publishing
- Content assignments for content-creator and content-writer
- Scheduling recommendations for engagement-strategist
What's inside
8 sections: calendar architecture, 4-week template, batching schedule, distribution plan, seasonal calendar, output format, verification checklist, failure modes
Change this for your project
- Replace
docs/marketing/calendar/with your own storage path for calendar artifacts - Replace
[Brand/Product]and[Month/Quarter]in the output format with your actual brand and timeframe - Replace
[Month Year]in the 4-week calendar template with the target month and year
Where it goes
Save as AGENTS.md in your repository root. Read by Codex, Cursor and other agents that follow the AGENTS.md convention.
Worth borrowing
- 70/20/10 content mix rule (planned, topical, promotional) as a reusable planning heuristic
- Batching schedule that separates creation days from publishing days to avoid overcommitment
- Same-day distribution cascade for long-form content across multiple platforms
