Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00086 | $0.02799 |
| Opus 5.5 | $0.00034 | $0.01120 |
| Sonnet 5.5 | $0.00017 | $0.00560 |
| Haiku 4.5 | $0.00009 | $0.00280 |
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.
How it starts
The opening of the file, as written. The whole thing — 271 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Concept Engine — Data-Grounded Creative Concept Generator
Phase 0: Orient
- Acknowledge: "I'll map your input through the creative strategy framework and produce grounded concepts."
- Ask for input: "What's the raw input — brainstorm notes, meeting transcript, competitor observation, or blank slate?"
- 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 innovationformat— emphasize format experimentationaudience— emphasize audience expansion- Default: balanced across all dimensions.
1b. Load Context

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

concept-engine is a skill published in the GitHub repository Motion-Creative/motion-creative-plugin (24 stars, last pushed 4mo ago), licensed MIT. It adds 86 tokens to every session and 2,799 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
