Build Brief

"What creative concept do you want to brief? You can describe the idea, paste a concept from /create-concepts, or tell me the audience/angle you want to target and I'll build the concept."

1b. Get Auth Context

Call get_auth_context() for workspaceId.

Phase 2: Gather Strategic Inputs (Parallel)

The SPEND call must come first (it returns goalMetric and spendThreshold). Then dispatch remaining calls in parallel.

1. get_creative_insights(workspaceId, "SPEND", datePreset="LAST_30_DAYS", limit=5, withAggregatedInsights=true) — spend leaders + account-level aggregates

→ Extract goalMetric and spendThreshold from the response. If goalMetric.isCustomConversion is true, find the matching conversion in the customConversions array and include ["{id}_cost", "{id}_count"] in tableKPIs on all subsequent calls. Use goalMetric for all efficiency-sorted calls.

2. get_workspace_brand(workspaceId) — brand positioning, voice, visual identity, tone constraints
3. get_glossary_values(workspaceId) — creative taxonomy for alignment
4. get_creative_insights(workspaceId, insightType=goalMetric, datePreset="LAST_30_DAYS", limit=5) — efficiency leaders by workspace goal metric for visual reference

If the concept references a competitor or specific brand: 5. search_brands(query, workspaceId) or get competitor creatives for reference examples

2a. Load Settings & Methodology

1. Read ${CLAUDE_PLUGIN_ROOT}/motion-creative.config.md for org-specific configuration. If the file does not exist, use these defaults and suggest the user run /customize:
   • primary_kpi: use goalMetric from first get_creative_insights response
   • default_date_preset: LAST_30_DAYS
   • brief_format: default
   • production_capabilities: all formats
   • max_production_difficulty: High
   • Brand guidelines: pull from get_workspace_brand
2. Read the creative-strategist skill and references/brief-template.md for the output structure and quality bar.
3. Use default_date_preset from settings as the datePreset for all calls unless the user specified a date range.

Settings influence:

• If brief_format is "custom" and references/custom-brief-template.md exists, use that template instead of the default.
• Use production_capabilities and max_production_difficulty to constrain Deliverables section.
• Use brand guidelines (voice, do's/don'ts, positioning) as hard constraints on Copy and Visual Approach.
• Use primary_kpi to set the Success Metrics section — what "good" looks like depends on what the team optimizes for.
• Use target_demographics to inform audience-specific copy choices.

Phase 3: Build the Concept (if needed)

If the user provided a full concept (from /create-concepts or detailed description), use it directly.

If the user provided a partial concept (just an audience, or just a hook idea), build it out:

1. Use the performance data from Phase 2 to identify relevant winning patterns
2. Use brand context to set voice and positioning constraints
3. Use glossary values to align with the workspace's creative taxonomy
4. Flesh out the concept following references/concept-standards.md

The concept must be clear before writing the brief — audience, hook approach, messaging angle, and format all need to be defined.

Phase 4: Pull Reference Creatives

4a. Own Account Reference

From the goalMetric top performers (Phase 2), select the creative that best matches the brief's intended format and visual approach. This becomes the Visual Example in the brief — a real ad from the brand's account that shows "make it look like this."

4b. Competitor Reference (if relevant)

If the concept was inspired by competitor activity, pull 1-2 competitor creatives as additional reference:

• get_inspo_creatives(brandId, workspaceId, limit=5, sort="NEWEST", status="ACTIVE")

4c. Pull Transcripts

For the 2-3 most relevant reference creatives (own + competitor), pull transcripts with get_creative_transcript. These inform the Copy section — what hooks, pacing, and CTAs work in similar creatives.

Phase 5: Generate the Brief

Follow the structure in references/brief-template.md exactly.

Pre-Brief Reasoning

Before the brief, write 3-5 casual bullets showing the key inputs:

• What performance insight shaped the direction
• Who the creative is for and what tension it taps into
• What reference creatives informed the approach
• Any brand constraints that influenced choices

The Brief

BRIEF: [Title]

CONCEPT OVERVIEW
[What we're making and why. 1-2 sentences. No jargon.]

COPY
[For video: timestamped script with spoken copy + text overlays per beat.
 For static: headline, subheading, supporting text, CTA.
 Write exactly what appears on screen or is spoken.
 No placeholders. The hook must be a specific verbatim line.]

VISUAL APPROACH
[For video: opening beat, background, pacing, production style, tone.
 For static: composition, layout, key visual elements.
 Specific enough that two designers would make similar things.]

DELIVERABLES
[Number of assets, format, dimensions, duration. No rationale.]

VISUAL EXAMPLE
[Reference creative from own account that shows how this should look.
 Include creative ID if available. Note if no strong match exists.]

SUCCESS METRICS
[Which insightTypes to watch. What "good" looks like.
 When to evaluate. What to diagnose if underperforming.]

Hook Requirement

Every brief must include a specific, verbatim hook — the actual opening line. Not "start with a question about X" but the exact words. The hook must follow the persuasive attribute standard: direct, pressured, specific.

Constraint Application

• All copy must match brand voice from get_workspace_brand AND settings brand guidelines (settings may have stricter rules)
• Messaging must align with brand positioning
• Creative Don'ts from settings are hard constraints — never include anything on the don't list
• Creative Do's from settings should be incorporated where natural
• Concepts must not replicate existing ads from the account (cross-reference with performance data)
• Flag any compliance concerns if the hook or body makes strong claims
• If settings specify max_production_difficulty, don't exceed it in the brief

Quality Gate

Before presenting the brief, verify: Can a creator read this and NOT ask "what do you want me to make?" Check: Is the hook verbatim (not "start with a question about X")? Is the visual obvious on first read? Is the awareness stage clear in every line? Does every section change what gets made? Revise any section that fails.

Phase 6: Output

Present the pre-brief reasoning bullets, then the brief itself. Render the brief as-is — do not add strategy sections, next steps, or concept cards after it.

End with: "This brief is ready for your creative team. Want me to adjust anything, or brief another concept?"

Quality Bar

Before delivering, check against references/brief-template.md quality bar:

• Can it be executed without a meeting? If not, add detail.
• Is the visual obvious immediately? If not, be more specific in Visual Approach.
• Does every section change what the creator does? If a section is generic, cut it or make it specific.
• Is the hook a real line, not a placeholder? If it says "something like" or "[insert]", rewrite it.
• Could a creator ask "what do you want me to make?" If yes, the brief is not done.

Error Handling

• No concept provided and user skips AskUserQuestion: Generate a concept from the top-performing creative patterns in the account. Note that the concept was auto-generated.
• Brand context unavailable: Proceed without voice constraints. Note the gap — copy may need voice adjustment.
• No reference creatives match: Note in Visual Example section that no strong match exists. Proceed without.
• Transcript calls fail: Write the Copy section from concept and brand context alone. Note reduced reference detail.
• Very sparse data overall: Generate the brief with reduced confidence. Flag: "Limited performance data — this brief is based on brand context and creative fundamentals rather than proven account patterns."
