creative-generate

creative-generate is a skill for Claude Code from logly/mureo. It costs 131 tokens per session (4,921 once invoked), scanned A, original, Apache-2.0.

A workflow for creating advertising images and banners from a strategy brief. It separates the main visual artwork from the accurately typeset text and produces variants for display or social formats.

In plain words
What is it for?
Use it to create text-free key visuals, compose banners, generate ad variations, and review candidates against a brand strategy.
Why use it?
It gives each part of an ad—the image, wording, and final layout—a defined place in the creation process.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is PREREQUISITE: Read `../_mureo-shared/SKILL.md` for auth, security rules, output format, and **Tool Selection** (Read/Write on Code, `mureo_strategy_*` / `mureo_.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Excessive Agency · line 52
    Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.
    Fix: Set explicit rate limits, timeouts, and resource quotas for API calls, file operations, and compute. Implement circuit breakers for runaway loops.

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

creative-generate 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 today.

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 — 352 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Creative Generate

PREREQUISITE: Read ../_mureo-shared/SKILL.md for auth, security rules, output format, and Tool Selection (Read/Write on Code, mureo_strategy_* / mureo_state_* MCP on Desktop / Cowork).

Tool names below refer to the built-in platforms; a namespaced variant (see _mureo-shared → Namespaced built-in variants) is used with its prefix substituted.

Produce professional, on-brand ad creatives — a text-free key visual plus composed banners in the operator's target formats — from a strategy-grounded brief. Quality comes from separating three layers and giving each to the right tool: image models make the picture (they are terrible at text, especially Japanese), an HTML/CSS + headless-Chromium composer lays down pixel-perfect typography, and you are the art director who scores every candidate before anything ships. See docs/creative-studio.md for the architecture and provider setup.

Prerequisites

  • STRATEGY.md must exist (run the onboard skill first). Persona / USP / Brand Voice are the grounding for both copy and visuals.
  • At least one image provider available — either an API key configured (creative_studio credentials section, or the OPENAI_API_KEY / GEMINI_API_KEY / FAL_KEY env vars), or the local Codex CLI provider (codex on PATH + codex login), which needs no API key. Call creative_studio_providers_list to see what is available.
  • Composition (step 5) requires the optional extra: pip install 'mureo[creative]' then playwright install chromium. Without it creative_studio_compose returns a clear pip-hint error — you can still run steps 1-4 (brief, copy, visuals, scoring) and hand off the raw key visual.

Before you start: Run the Diagnostic preamble from ../_mureo-shared/SKILL.md — load learning insights (mureo_learning_insights_get) and consult advisors (mureo_consult_advisor) before drawing conclusions.

The 6-step workflow

1. Brief

  • Read STRATEGY.md for Persona (pain points, desires), USP, and Brand Voice (tone, palette cues, do/don't). On Code use Read; on Desktop / Cowork use mureo_strategy_get. This is the strategy file — there is no separate "brief" tool.
  • When the operator gives a landing-page URL, ground the brief in it: google_ads_landing_page_analyze (selling points, price, CTA, industry) and optionally google_ads_creative_research for angle inspiration. Skip these when no URL is available — do not invent an LP.
  • Confirm with the operator BEFORE generating: genre / product, the offer, the desired tone, and the target formats (which of the format matrix — feed 1:1, 4:5, story 9:16, the GDN sizes, RDA — they actually need). One confirmation round, then proceed; do not loop endlessly asking questions.

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.
