NPCsMarket Codex Plugin

English | 中文

English

NPCsMarket brings historical personas and practical thinking modes into Codex. Use it to discuss product positioning, design critique, competitive strategy, marketing narrative, systems leverage, debugging, and architecture through a figure's reasoning pattern and first-person voice.

Install

codex plugin marketplace add Lyshen/npcsmarket-skill --ref main
codex plugin add npcsmarket@npcsmarket

Start a new Codex task after installing so the plugin, skill, and MCP tools are loaded.

Try It

Copy one of these into Codex:

Use NPCsMarket. Pick 3 random NPCs for my product positioning, choose one, and answer through that figure's reasoning pattern and first-person voice.

Use NPCsMarket. Pick 3 random NPCs for this launch plan, choose one, and debate me through that figure's historical frame.

Use NPCsMarket. Ask Peter Drucker to audit our ICP, pricing, and first sales motion.

Use NPCsMarket. Ask Sun Tzu to find our competitive wedge before launch.

Use NPCsMarket. Ask Donella Meadows to find leverage points in our activation funnel.

Use NPCsMarket. Ask Marcel Duchamp to reframe our landing page and category story.

Use NPCsMarket. Ask Edward Said to critique the market narrative we inherited.

Use NPCsMarket. Ask Socrates to turn this roadmap into uncomfortable product-discovery questions.

Use NPCsMarket. Ask Alan Turing to reason about edge cases in this agent workflow.

What It Adds

• random_npc: get 1 or 3 historical persona candidates.
• compose_prompt: build a focused persona prompt for a topic and mode.
• create_share: publish a short user-approved excerpt as a public share page.
• send_feedback: report a simple user-approved good, bad, or other experience signal.
• npcsmarket-companion: a Codex skill that decides when to use the NPCsMarket tools.

The persona tools are read-only. create_share only runs after explicit approval and publishes the excerpt you provide.

CLI

npm i -g @npcsmarket/skill@latest
npc-skill random --count 3

npc-skill compose \
  --name "Donella Meadows" \
  --topic "Find leverage points in our activation funnel" \
  --mode advisor

npc-skill share \
  --name "Donella Meadows" \
  --slug meadows \
  --topic "Writing as a thinking channel" \
  --title "Writing as context reconstruction" \
  --excerpt "A short excerpt the user explicitly approved for public sharing." \
  --consent

Sharing is opt-in. Only the excerpt you pass to --excerpt is sent for the public share page.

npc-skill feedback --sentiment good --slug meadows --note "The persona stayed in voice."

If you want NPCsMarket to contact you about a feedback report, add --contact-email [email protected]. Contact email is optional and only used for admin follow-up.

Privacy

NPCsMarket sends the topic you provide to https://npcsmarket.com when composing a prompt bundle. Sharing sends only the excerpt you approve. Feedback sends the sentiment, optional note, and optional contact email only when you provide one for follow-up. Do not include secrets, full source files, credentials, or private customer data. The package may create a local client id in ~/.npcsmarket-skill/config.json for lightweight diagnostics.

安装

包含内容

• random_npc：随机获取 1 个或 3 个历史人物视角。

隐私

NPCsMarket 在生成 prompt bundle 时会把你输入的话题发送到 https://npcsmarket.com。不要输入密钥、完整源码、凭据或客户隐私数据。这个包可能会在本地 ~/.npcsmarket-skill/config.json 创建一个 client id，用于轻量诊断。

分享功能需要显式确认。只有你传给 --excerpt 的内容会用于公开分享页。 反馈可以选择留下联系邮箱，用于 admin 后续联系了解问题；不填则不会发送。
