concept-engine

concept-engine is a skill for Claude Code from Motion-Creative/motion-creative-plugin. It costs 86 tokens per session (2,799 once invoked), scanned A, original, MIT.

A creative-planning guide that turns rough material—such as brainstorm notes, meeting transcripts, competitor observations, or a blank idea—into structured advertising concepts. It uses audience, customer problem, awareness stage, format, hook, and performance data to shape the concepts.

In plain words
What is it for?
Use it to generate two to five ad concepts, with emphasis on hooks, formats, audiences, or a balanced mix. The concepts can then feed into an advertising brief or hook-writing task.
Why use it?
It gives unstructured ideas a consistent direction and connects them to available advertising results. This makes the output easier to develop into a brief or advertising copy.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

concept-engine scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Concept Engine — Data-Grounded Creative Concept Generator


Phase 0: Orient

  1. Acknowledge: "I'll map your input through the creative strategy framework and produce grounded concepts."
  2. Ask for input: "What's the raw input — brainstorm notes, meeting transcript, competitor observation, or blank slate?"
  3. Connected workflow: After concepts, you can brief one (/build-brief), write hooks for it (/write-hooks), or iterate on a specific angle.

If the user already provided raw input in their message, skip questions and proceed.


Transform any input into structured, briefable ad concepts grounded in performance data and the Creative Strategy Engine framework.


Phase 1: Discovery

1a. Parse Arguments

  • Raw input ($ARGUMENTS): The source material. Can be anything — a raw idea, meeting transcript, brainstorm notes, competitor observation, a single sentence, or empty.
  • --count: Number of concepts to generate. Default: 3. Range: 2-5.
  • --focus: Weight for concept generation:
    • hook — emphasize hook innovation
    • format — emphasize format experimentation
    • audience — emphasize audience expansion
    • Default: balanced across all dimensions.

1b. Load Context

  1. Read ${CLAUDE_PLUGIN_ROOT}/motion-creative.config.md for brand guidelines, production constraints, primary KPI, target audience. 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
    • default_creative_limit: 10
    • production_capabilities: all formats
    • max_production_difficulty: High
    • Brand guidelines: pull from get_workspace_brand
  2. Read ${CLAUDE_SKILL_DIR}/../creative-strategist/SKILL.md for methodology.
  3. Read ${CLAUDE_SKILL_DIR}/../creative-strategist/references/concept-standards.md for quality bar.
  4. Read ${CLAUDE_SKILL_DIR}/references/creative-strategy-engine.md for the full strategic framework.
  5. Use default_date_preset from settings as the datePreset for all calls unless the user specified a date range. Use default_creative_limit from settings as the limit unless the user specified otherwise.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
