Coze (扣子) bot prompt builder: role, skills, workflow, limits, opening line, guiding questions. In your browser.
Coze Bot Prompt Builder
Assemble a clean, structured prompt for a 扣子 Coze bot from a simple form — persona, skills, workflow, limits, opening line and guided questions — then copy it straight into the Coze bot builder's Persona & Prompt panel. Everything is built in your browser; nothing is sent to a server and no model is called.
Tip: this builder only assembles text. Copy the result into the 扣子 Coze bot builder yourself — no model is called and nothing is sent anywhere.
How the 扣子 Coze bot prompt builder works
Start with the role / persona
In the first box, give the 扣子 Coze bot an identity and remit — e.g. "an e-commerce customer-service assistant" or "a professional résumé-polishing advisor". This line opens the prompt ("你是…") and sets the bot's voice, stance and scope; it is the highest-leverage sentence you write.
Fill in skills and workflow
Next, list the skills the bot should have (what it can do and is good at) and the standard workflow for handling a request (what it asks first and in what order it answers). Skills keep the bot's boundaries clear; the workflow makes it follow the same steps every time.
Set limits, opening line and guided questions
Spell out the limits / constraints (topics to refuse, rules it must follow), write the opening line the user sees first, and prepare a few guided questions / quick commands to help users get started. These fields decide the live experience and reliability of the bot.

How the 扣子 Coze bot prompt builder works
A Coze bot is only as good as its persona prompt
When you build a bot on 扣子 Coze — ByteDance's bot and agent platform — the single most important thing you write is the bot's "persona and reply logic". Behind the friendly editor, that field is a structured prompt: it names the bot's role, lists its skills, fixes the workflow it follows, and states the limits it must obey. The quality of every conversation the bot ever has depends far more on how clearly you structure that prompt than on any clever phrase. This builder keeps that structure for you: fill the fields and it joins them into a clean prompt with a leading "你是…" role line followed by clearly headed sections — skills, workflow, limits, opening line and guided questions — each prefixed with a Markdown-style heading the model can read at a glance, ready to paste into Coze.
The single highest-leverage line is the role. "你是一位跨境电商英文客服" steers the bot's viewpoint, vocabulary and scope in one sentence — far more efficiently than a paragraph of adjectives. After the role, the skills and workflow do the heavy lifting: the skills say exactly what the bot can do and is good at, narrowing its scope so it stays on-topic, and the workflow gives it a fixed order of operations so that two users asking similar things get a consistent, predictable experience. A good rule of thumb is to make each field concrete and specific: instead of "be helpful", say "always confirm the order number first, then explain the return policy in plain language".
"A weak Coze bot is usually a weak persona prompt — not a weak platform. Structure the persona, skills, workflow and limits, and the same bot behaves far more reliably."
Workflow and limits separate a demo bot from one you can ship
The fields people skip and regret are limits, the opening line and guided questions. The limits tell the bot which topics to refuse, which rules it must always follow, and which facts it must never invent — and they are what make a bot safe to put in front of real users. The opening line is the first thing a visitor reads, so it should say in one sentence what the bot is for. The guided questions act as a built-in demo: a few sample prompts a newcomer can send in a single click, which sharply raises the share of people who use the bot the way you intended instead of bouncing off a blank chat box.
Because the output is structured plain text, the prompt is easy to version, review and reuse: keep one in a document, tweak a field, and paste the new version back into Coze. Treat the first persona as a draft — deploy it, watch where the bot drifts off-topic or answers something it should refuse, and tighten the matching field. Two or three rounds of that usually turn a vague, rambling bot into one that stays in its lane and feels professional. And because the whole tool runs locally in your browser, you can iterate freely — edit one field, copy again, test — without anything you type ever leaving your device, being sent to a model, or being stored. The result is the kind of persona prompt a careful bot builder would write by hand, only assembled in seconds.
About Building 扣子 Coze Bots — 10 Key Points
扣子 Coze is ByteDance's bot / agent building platform; a bot's "persona and reply logic" is essentially a structured prompt.
Listing role, skills, workflow, limits, opening line and guided questions separately is easier for a bot to follow reliably than one long paragraph.
A clear "you are…" role line is usually the highest-leverage sentence in the whole bot prompt, setting its viewpoint and scope.
A skills field that states what the bot is good at and can do effectively narrows its scope and cuts down off-topic answers.
A workflow gives the bot a fixed order of operations (confirm the need first, then answer step by step), so similar requests get a consistent experience.
Explicit limits / constraints (topics to refuse, things never to invent) are the key to cutting confident hallucinations.
A good opening line tells the user what the bot is for the moment they enter the chat, lowering the cost of trial and error.
Guided questions / quick commands act as a demo for new users and markedly raise the share of people who use the bot correctly.
Keep a bot prompt concise: an over-long prompt eats context and dilutes the persona and rules that matter.
This tool assembles the prompt entirely in your browser — your input is never uploaded, never sent to a model, and never stored.
Frequently Asked Questions
- No. It simply joins the fields you fill in into a structured bot prompt using a fixed template, entirely in your browser. It does not call 扣子 Coze or any model, and does not go online. You copy the generated prompt and use it inside the Coze platform yourself.
- No. This is an independent prompt builder for 扣子 Coze users, with no affiliation or partnership with ByteDance or Coze. It helps you assemble persona, skills, workflow and limits into clean text that you then paste into your Coze bot configuration.
- Paste it into the "Persona & Prompt" section of the bot editor. The role maps to the bot's identity, the skills / workflow / limits are the reply logic, and the opening line and guided questions map to Coze's opening message and suggested-question settings.
- No. Empty fields are omitted automatically. A role and a skills entry alone give you a usable bot prompt; adding the workflow, limits, opening line and guided questions is what makes the live bot steadier and easier to use.
- It becomes the opening line of the prompt ("你是…") and sets the bot's viewpoint, tone and scope. Making it specific — e.g. "an English customer-service agent for cross-border e-commerce, expert in returns" — is usually more effective than piling on requirements.
- No. All assembly happens locally in your browser with plain JavaScript. Nothing you type is sent to any model, server or third party, and nothing is stored.
- Describe the order in which the bot handles a request in short steps — e.g. "① confirm the user's specific need; ② give a solution and explain the reasoning; ③ ask whether further help is needed". The clearer the workflow, the more consistent the bot's answers.
- Limits tell the bot what not to do, which topics to refuse, and which information never to invent. They are the key to a bot you can ship, and they markedly reduce confident, wrong or out-of-scope output.
- The opening line is the first message a user sees, explaining what the bot is for; the guided questions / quick commands are a few sample prompts a user can send in one click, helping newcomers get started and see what the bot can do.
- Completely free, with no account or sign-up and no usage limit. It runs in your browser and collects no data.
