What its author says it does

Copied from the file, not written here

Create a structured content brief using the Kai CMO Harness brief schema. Selects persona, defines angle, sets quality targets. Use when "create a brief", "content brief", "plan this content", "brief for [topic]", "what persona should I use", or before any content creation to define the strategy. Outputs a brief that /kai-write and /kai-email-system consume.

Create a content brief using the Kai CMO Harness schema. Every piece of content starts with a brief.

Phase 0: Load Product Context

Check if MARKETING.md exists in the project root (same directory as CLAUDE.md, README.md, package.json).

If it exists: Read it — skip product discovery questions. It has the product name, ICP, value prop, monetization, brand voice, current channels, and competitive landscape.

If it does NOT exist: Auto-explore the codebase to create it in the project root (next to CLAUDE.md). Do NOT ask the user what the product is. Read CLAUDE.md, README.md, PROJECT.md, package.json, landing pages, and any project files. Search for email/ad/analytics config. Then create MARKETING.md using the template from /kai-email-system. Present draft to user for confirmation.

Process

1. Gather Inputs

Read from MARKETING.md. Only ask about things not covered there:

What are we writing? (blog, email, LinkedIn, ad, etc.)
What's the topic/keyword?
Who's it for? (suggest a persona from the list below)
What's the angle? Not just the topic — the specific frame. "AI for law firms" is a topic. "Why law firms lose 40% of leads after 5pm" is an angle.
What should the reader do? (CTA)
Any proof/data we can use?

2. Select Persona

Read knowledge/personas/_persona-index.md for the full list. Quick reference:

Persona	Core Hook	Best For
Competent Cog	"The system treats you like a child"	B2B SaaS, enterprise
Shock Absorber	"Accountability without authority"	Middle management
Ghosted Applicant	"The game is rigged"	Job seekers, HR tech
Subscription Serf	"They bet you won't fight back"	Consumer SaaS
System Manager	"No village, only vendors"	Parents, household managers
Admin Martyr	"Death by a thousand tasks"	Admin/ops roles
Obsolescence Anxious	"Working hard isn't the variable"	Career-concerned professionals
Credibility Fighter	"You're not crazy"	Experts fighting misinformation

Load the full persona file before writing the brief. It contains language patterns, pain points, and hooks that shape the angle.

3. Output Brief

Follow the schema from harness/brief-schema.md:

{
  "target_site": "[site]",
  "target_keyword": "[primary keyword]",
  "secondary_keywords": ["2-3 terms"],
  "format": "[blog|linkedin|email|ad|press]",
  "persona": "[archetype name]",
  "angle": "[specific frame]",
  "hook_options": ["Hook 1", "Hook 2", "Hook 3"],
  "audience_pain": "[single biggest frustration]",
  "proof_available": "[data, stories, examples]",
  "cta": "[desired action]",
  "word_count_target": 0,
  "publish_date": "YYYY-MM-DD"
}

4. Validate

Before passing the brief to /kai-write:

hook_options has exactly 3 variants
angle is differentiated from target_keyword (not a restatement)
proof_available references actual data or a named example (not vague)
