Your framework

Claude Code docs

No account or Python needed. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/modu-ai-content-copywriting/SKILL.md https://app.decimal.ai/s/modu-ai-content-copywriting/SKILL.md

Keep it pinned and updatable

pip install "decimalai>=0.15"
decimalai skills add modu-ai-content-copywriting
claude --plugin-dir "$(git rev-parse --show-toplevel)/.agents"

This gets SKILL.md only. The skill's 4 other files are not included. The other two ways bring them.

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install modu-ai-content-copywriting

The plugin needs python3 and curl on your machine.

No tools at all. Claude Code picks it up in its next session.

Claude Agent SDK docs

agent_config() hands your agent the skill. With no DecimalAI key it reads your project's files and sends nothing. Needs SDK 0.27 or newer.

Install

pip install "decimalai[claude-agent-sdk]"

Prefer its own loader? ClaudeAgentOptions(plugins=[skills_plugin()], skills="all") reads the same folder. Use one or the other: a skill delivered both ways reaches the prompt twice.

The same install from Python, for a notebook or a setup script. agent_config() hands your agent the skill. With no DecimalAI key it reads your project's files and sends nothing. Needs SDK 0.27 or newer.

.agents/skills/modu-ai-content-copywriting/SKILL.md

Give it to your agent

from pathlib import Path
from langchain.agents import create_agent

skill = Path(".agents/skills/modu-ai-content-copywriting/SKILL.md").read_text()
agent = create_agent("openai:gpt-5.4-mini", tools=[], system_prompt=f"You are a helpful agent.\n\n{skill}")
result = agent.invoke({"messages": [{"role": "user", "content": "Hello!"}]})

This gets SKILL.md only. The skill's 4 other files are not included.

CrewAI docs

CrewAI's own skill loader reads the installed folder. No DecimalAI account needed.

Install

pip install "decimalai>=0.16" "crewai>=1.15.27"
decimalai skills add modu-ai-content-copywriting

Add it to your agent

import decimalai.crewai
from crewai import Agent, Crew, Task

agent = Agent(
    role="Support", goal="Help the customer", backstory="A support agent.",
    llm=llm,                               # your own CrewAI LLM
    skills=decimalai.crewai.skills(),      # the installed folder

)
task = Task(description="Hello!", expected_output="an answer", agent=agent)
Crew(agents=[agent], tasks=[task]).kickoff()

The same install from Python, for a notebook or a setup script. CrewAI's own skill loader reads the installed folder. No DecimalAI account needed.

Install

pip install "decimalai>=0.16" "crewai>=1.15.27"

Add it to your agent

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("modu-ai-content-copywriting")
if result.exit_code:
    raise SystemExit(result.problems)

No DecimalAI package. CrewAI's own loader reads the folder, and nothing pins or updates it.

Copy SKILL.md

Save it in your project, as

.agents/skills/modu-ai-content-copywriting/SKILL.md

Give it to your agent

from pathlib import Path
from crewai import Agent, Crew, Task

agent = Agent(
    role="Support", goal="Help the customer", backstory="A support agent.",
    llm=llm,                         # your own CrewAI LLM
    skills=[Path(".agents/skills")],
)
task = Task(description="Hello!", expected_output="an answer", agent=agent)
Crew(agents=[agent], tasks=[task]).kickoff()

This gets SKILL.md only. The skill's 4 other files are not included.

Google ADK docs

agent_config() hands your agent the skill. With no DecimalAI key it reads your project's files and sends nothing. Needs SDK 0.27 or newer.

Install

pip install "decimalai[adk]"
decimalai skills add modu-ai-content-copywriting

Add it to your agent

from decimalai.adk import DecimalAIPlugin, agent_config
from google.adk.agents import LlmAgent
from google.adk.apps import App

# With no DECIMAL_API_KEY this reads the skills your project lists, from disk.
support = agent_config("support", fallback="You are a helpful agent.")

agent = LlmAgent(
    name="support",          # ADK needs a Python identifier
    model="gemini-3.5-flash",
    instruction=support.instruction,  # your prompt, then the skill list
    tools=[*support.tools],           # your tools, then load_skill
)
# DecimalAIPlugin makes each invocation of runners built from this App one trace.
app = App(name="support", root_agent=agent, plugins=[DecimalAIPlugin()])

Prefer ADK's own loader? SkillToolset(skills=decimalai.adk.skills(), ...) reads the same folder. Use one or the other: a skill delivered both ways reaches the prompt twice.

Install

pip install "decimalai[adk]"

Add it to your agent

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("modu-ai-content-copywriting")
if result.exit_code:
    raise SystemExit(result.problems)

from decimalai.adk import DecimalAIPlugin, agent_config
from google.adk.agents import LlmAgent
from google.adk.apps import App

# With no DECIMAL_API_KEY this reads the skills your project lists, from disk.
support = agent_config("support", fallback="You are a helpful agent.")

agent = LlmAgent(
    name="support",          # ADK needs a Python identifier
    model="gemini-3.5-flash",
    instruction=support.instruction,  # your prompt, then the skill list
    tools=[*support.tools],           # your tools, then load_skill
)
# DecimalAIPlugin makes each invocation of runners built from this App one trace.
app = App(name="support", root_agent=agent, plugins=[DecimalAIPlugin()])

Prefer ADK's own loader? SkillToolset(skills=decimalai.adk.skills(), ...) reads the same folder. Use one or the other: a skill delivered both ways reaches the prompt twice.

No DecimalAI package. The whole skill goes in every prompt, and nothing pins or updates it.

Copy SKILL.md

Save it in your project, as

.agents/skills/modu-ai-content-copywriting/SKILL.md

Give it to your agent

from pathlib import Path
from google.adk.agents import LlmAgent

skill = Path(".agents/skills/modu-ai-content-copywriting/SKILL.md").read_text()
agent = LlmAgent(
    name="support",

)

Install

pip install "decimalai[pydantic-ai]"

)
# In a notebook or async code: result = await agent.run("Hello!")
result = agent.run_sync("Hello!")

On the Pydantic AI harness, decimalai.pydantic_ai_harness.skills(project) uses its own loader instead.

Install

시작

사용자의 제품·서비스, 대상 독자, 채널, 원하는 행동, 브랜드 문체와 금지 표현을 확인한다. 실제 가격·할인·기간·재고·성과·인증·후기와 비교 대상 자료를 받는다. 없으면 해당 주장을 사용하지 않거나 확인이 필요한 빈칸으로 남긴다. 사용자가 후보 수를 지정하면 그 수에 맞추고, 아니면 서로 다른 메시지 방향의 소수 후보를 제시한다.

작성

고객이 실제로 겪는 상황과 제품이 확인된 범위에서 해결하는 일을 연결한다. AIDA·PAS·FAB 같은 구성은 필요할 때만 참고하고, 틀에 맞추려고 공포·긴박감·혜택을 만들지 않는다.
제목·본문·CTA가 같은 약속을 하게 한다. 클릭 뒤 랜딩 화면의 내용과 가격·조건이 다르면 수정한다.
숫자·최상급·비교·전후 효과·전문가 추천·고객 인용은 출처와 적용 조건을 확인한다. 근거가 없으면 덜 강한 표현으로 바꾸거나 삭제한다.
매체의 현재 글자 수·표시 위치·정책을 확인한다. 광고성 메시지 발송은 수신 동의·광고 표시·수신거부 요건도 별도 검토한다.
한국어 문장은 브랜드의 실제 말투에 맞춰 다듬는다. 자연화를 이유로 날짜·가격·조건·법적 고지·불확실성을 바꾸지 않는다. 카피 검수 안내를 따른다.

결과

후보별로 사용 채널, 주된 메시지, 문구, 실제 근거, 아직 확인할 주장, 랜딩 화면과의 대조 결과를 적는다. 광고 캠페인 전체 설계는 캠페인 참고, 영상·이미지 스토리는 비주얼 스토리 참고를 필요할 때 연계한다. 일반 이미지는 ChatGPT 대화의 기본 이미지 도구를 확인해 사용한다. ChatGPT Images 2.5 요청도 현재 대화의 기본 이미지 도구로 생성·편집한다. 모델 표시가 없으면 개별 호출의 정확한 모델은 미확인으로 보고한다. Flare·Sunburst API 모델 ID 지정은 설치된 moai-media:media-codex-image의 별도 API 경로와 비용·승인 절차를 따른다. Higgsfield 지정 요청은 공식 연결의 실제 모델을 확인하고 설치된 경우 moai-media:media-higgsfield-image를 사용한다.

공정위의 부당 표시·광고 안내에 따라 거짓·과장, 기만, 부당 비교, 비방 가능성을 검토한다. 의료·식품·금융 등 업종별 문구는 해당 최신 규정과 전문 검토가 필요할 수 있다. 후보의 효과는 실제 시험 전에는 성과로 보고하지 않는다.
