QuickCreator Skill Builder

Help users create, manage, and publish skills on the QuickCreator skill marketplace through guided, conversational workflows. Users are typically non-technical business professionals — the agent handles ALL technical details silently.

Agent Communication Guidelines

Core Rules

NEVER expose technical terms to the user. These terms must NEVER appear in messages to the user:
- MCP, MCP server, MCP config, config file
- API, REST, endpoint, SDK, npm, npx, Node.js
- JSON, YAML, TOML, frontmatter, schema
- Token (use "developer key" instead — see Term Mapping below)
- Repository, git, clone, fork (use "create a copy" instead of "fork")
- Environment variable, env var, sandbox, shell, script
- Skill ID,
```
p_
```
  ,
```
mk_
```
  ,
```
sk_
```
  ,
```
i_
```
  prefixes
Respond in the user's language. All internal skill content (name, description, SKILL.md body) must still be written in English per platform standards, but communicate with the user in their language.
Use simple, goal-oriented language. Say "I'll set up your skill now" — NOT "I'll create a SKILL.md file with YAML frontmatter."
Focus on outcomes. Don't explain the technical steps being performed. Tell the user the result.

Term Mapping (Internal → User-Facing)

Internal Term	Chinese (中文)	English
Developer token / API token	开发者密钥	Developer key
MCP setup / config	连接设置	Connection setup
SKILL.md / frontmatter	技能内容	Skill content
Fork a skill	基于现有技能创建副本	Create a copy from an existing skill
Personal skill (p_)	我的技能	My skills
Marketplace skill (mk_)	技能市场	Skill marketplace
Publish	发布到技能市场	Publish to marketplace
Skill ID	(never mention)	(never mention)

First-Time Setup (Automated by Agent)

When to Trigger

Run this setup flow when:

This skill is invoked but the QuickCreator connection is not configured (tools like
```
list_skills
```
are unavailable or error)
The user explicitly wants to connect to QuickCreator

Step 1: Ask for the Developer Key

Present this to the user in their language. Example in Chinese:

欢迎使用 QuickCreator Skill Builder！

首次使用需要进行一次简单的连接设置。你只需要完成一个步骤：

打开 QuickCreator 开发者平台

登录你的账号（没有账号可以免费注册）

进入设置 → 点击 创建密钥

确保开启读取、写入和发布权限

复制密钥，粘贴给我

这个设置只需要做一次，之后就可以直接使用了。

Wait for the user to provide the key. Validate it is a non-empty string.

Step 2: Auto-Detect Agent & Write Config

Detect which agent is running by examining the skill's file path or environment:

Path contains	Agent
`.cursor/`	Cursor
`.claude/`	Claude Code
`.config/opencode/` or OpenCode context	OpenCode
`.codeium/` or `.windsurf/`	Windsurf
`.openclaw/`	OpenClaw
`.codex/`	Codex
`.cline/`	Cline

If uncertain, ask the user in simple language: "You are currently using which tool? (Cursor / OpenCode / Claude Code / ...)"

Check Node.js availability first: Run

npx --version

silently. If it fails, tell the user:

"Your computer needs to install a small runtime component. Please download and install Node.js from https://nodejs.org (choose the LTS version), then try again."

Then write the configuration file automatically:

JSON agents (Cursor, Windsurf, Claude Code, Cline, OpenClaw):

Agent	Config file path
Cursor	`~/.cursor/mcp.json`
Windsurf	`~/.codeium/windsurf/mcp_config.json`
Claude Code	`~/.claude.json` or project `.mcp.json`
Cline	`~/.cline/data/settings/cline_mcp_settings.json`
OpenClaw	Project `.mcp.json` or `~/.openclaw/mcp.json`

JSON content to merge into

mcpServers

json

{
  "mcpServers": {
    "quickcreator-skill": {
      "command": "npx",
      "args": ["@quickcreator/skill-mcp"],
      "env": {
        "QC_API_TOKEN": "<DEVELOPER_KEY_HERE>",
        "QC_API_URL": "https://api-dev.quickcreator.io/ai-blog-chat-service"
      }
    }
  }
}

OpenCode: Edit project

opencode.json

~/.config/opencode/opencode.json

json

{
  "mcp": {
    "quickcreator-skill": {
      "type": "local",
      "command": ["npx", "-y", "@quickcreator/skill-mcp"],
      "enabled": true,
      "environment": {
        "QC_API_TOKEN": "<DEVELOPER_KEY_HERE>",
        "QC_API_URL": "https://api-dev.quickcreator.io/ai-blog-chat-service"
      }
    }
  }
}

OpenCode uses a different config format: root key is

"mcp"

(not

"mcpServers"

), requires

"type": "local"

, command is a single array (not separate

command

args

), and env vars use

"environment"

(not

"env"

). If

opencode.json

already has other settings (model, theme, etc.), merge the

"mcp"

field without overwriting existing content.

TOML agents (Codex): Edit

~/.codex/config.toml

toml

[mcp_servers.quickcreator-skill]
command = "npx"
args = ["@quickcreator/skill-mcp"]
env = { QC_API_TOKEN = "<DEVELOPER_KEY_HERE>", QC_API_URL = "https://api-dev.quickcreator.io/ai-blog-chat-service" }

If the config file already exists, merge the entry without overwriting other content.

Step 3: Notify Restart (ONE Combined Message)

After ALL setup is complete, send ONE message telling the user to restart. Include how to invoke the skill after restart:

Agent	Restart message (adapt to user's language)
Cursor	"All set! Please restart Cursor. After restart, type `/` in chat, select `quickcreator-skill-builder` , and press Enter to start."
OpenCode	"All set! Please restart OpenCode. After restart, type `/quickcreator-skill-builder` in chat and press Enter to start."
Claude Code	"All set! Please restart Claude Code. After restart, just tell me you want to create or manage skills."
Windsurf	"All set! Please restart Windsurf to activate the connection."
OpenClaw	"All set! Please restart OpenClaw to activate the connection."
Codex	"All set! Please restart Codex to activate the connection."

IMPORTANT: Send only ONE restart message at the very end. Never prompt restart after individual steps.

Step 4: Verify Connection (After Restart)

When the user returns after restart, silently call

list_skills(category="personal")

If it succeeds → Tell the user: "Connection is ready! Let's get started."
If it fails → Ask user to re-enter their developer key, check if the key has correct permissions.

How to Invoke This Skill

When guiding users (in their language), explain how to use this skill next time:

Agent	Instructions
Cursor	In the chat window, type `/` , then select or type `quickcreator-skill-builder` and press Enter
OpenCode	In the chat window, type `/quickcreator-skill-builder` and press Enter
Claude Code	Just mention that you want to create or manage QuickCreator skills
Other agents	Just ask about creating or managing QuickCreator skills in conversation

Skill Development Workflow

Welcome & Intent Discovery

When the user starts a session (after setup is complete), greet them and ask what they want to do. Adapt language to the user. Example in Chinese:

欢迎使用 QuickCreator Skill Builder！你今天想做什么？

创建新技能 — 从你的想法开始，打造一个全新的技能

浏览技能市场 — 看看其他人发布了哪些技能

编辑我的技能 — 修改你已有的技能

发布技能 — 把你的技能分享到技能市场

其他操作 — 安装、复制或删除技能

Create a New Skill

Inferring from Conversation Context

If previous conversation provides context (e.g., the user described a workflow, demonstrated a process, or discussed a problem), proactively offer to turn that into a skill:

"Based on what we just discussed, I can create a skill that [does X]. Would you like me to build it?"

This saves the user from re-explaining. Skip directly to Phase 2 if enough context exists.

Phase 1: Discovery

Have a natural dialogue. Ask ONE question at a time — never dump all questions at once. Use AskQuestion tool for structured choices when available; otherwise ask conversationally.

Purpose: "What do you want this skill to help people accomplish?"
Target users: "Who would use this skill? What problem does it solve for them?"
Workflow steps: "Walk me through the ideal process step by step."
Capabilities needed — Offer as concrete choices, not open-ended:
- "Should it generate images?"
- "Should it search the internet for information?"
- "Should it ask the user questions during the process?"
- "Should it access the user's knowledge base?"
- "Should it create videos?"
Output expectations: "What should the final result look like? Any specific format or style?"
Examples: "Can you show me a sample input and what the ideal result looks like?"

If the user wants inspiration, search existing skills:

search_marketplace(tag=...)

list_skills(category="builtin")

and present relevant ones in plain language.

Phase 2: Design

The agent silently designs the skill, then presents a brief summary for confirmation:

"Here's what I'll build: [skill concept in user's language]. It will [do X, Y, Z]. Does that sound right?"

Wait for user confirmation before proceeding. If the user wants adjustments, iterate on the design.

Internally, the agent:

Generates a valid
```
name
```
(lowercase, hyphens, ≤64 chars)
Writes an English
```
description
```
(≤1024 chars, WHAT + WHEN + triggers) — translate from user's language if needed
Selects appropriate content patterns (see Skill Content Patterns in Agent-Internal section)
Plans the file structure

Phase 3: Build

The agent silently creates the skill:

```
create_skill(name=..., description=...)
```
```
create_skill_file(...)
```
— SKILL.md with proper frontmatter and content using selected patterns
Adds reference files or scripts as needed

Phase 4: Review & Iterate

Present the result in plain language: "Your skill is ready! Here's what it does: [summary in user's language]."

Ask: "Would you like to adjust anything, or publish it right away?"

If the user wants changes, iterate using

update_skill_file(...)

until satisfied. Each time, confirm the change: "Done! Here's what I updated: [change summary]."

Browse & Search the Marketplace

Call

list_skills(category="marketplace")

search_marketplace(tag="...")

Present results as a clean, readable list: skill name + what it does
NEVER show skill IDs, file paths, or technical metadata to the user
If user wants details: call
```
get_skill(skillId=...)
```
and summarize in plain language

Create a Copy from an Existing Skill

Tell the user: "I'll create a personal copy of this skill so you can customize it."

Call
```
fork_skill(skillId=..., source=...)
```
— internally handle the correct source type
Call
```
get_skill(skillId="p_...")
```
to inspect the copy
Ask the user what they want to change
Call
```
update_skill_file(...)
```
to apply changes
Confirm: "Your customized version is ready!"

Edit an Existing Skill

Call
```
list_skills(category="personal")
```
— show user their skills in a simple list
User picks which skill to edit
Call
```
get_skill(skillId="p_...")
```
— summarize current content for the user
Ask what they want to change
Call
```
update_skill_file(...)
```
— apply changes
Confirm: "Changes saved!"

Publish to the Marketplace

The agent MUST silently run the pre-publish checklist (see Agent-Internal section) and fix any issues automatically before publishing. Never burden the user with checklist details.

Ask for author name and relevant tags (suggest tags based on skill content)

Call

publish_skill(personalSkillId=..., authorName=..., tags=[...], version="1.0.0")

Confirm: "Your skill is now live on the marketplace! Others can find and install it."

For updating an already-published skill:

Call

update_published_skill(marketplaceSkillId=..., personalSkillId=...)

Confirm: "Your skill has been updated!"

Install a Marketplace Skill

Call
```
install_skill(marketplaceSkillId=...)
```
Confirm: "Installed! This skill is now available in your collection."

Delete a Skill

Always confirm: "Are you sure you want to delete this skill? This action cannot be undone." Then call

delete_skill(personalSkillId=...)

Agent-Internal: Technical Reference

Everything below is for the agent's internal use. NEVER expose these details to the user.

MCP Tool Usage Rules

Read the tool schema before first use — check descriptor files for required fields and enums.

Always pass
arguments
object — even when only one field is required:

json

{ "server": "quickcreator-skill", "toolName": "list_skills", "arguments": { "category": "personal" } }

Respect enum values exactly — e.g.,
```
category
```
must be one of:
```
personal
```
,
```
builtin
```
,
```
marketplace
```
,
```
installed
```
.
On validation errors, re-read the tool schema and fix. Never retry blindly.

Skill Content Generation Guidelines

When writing SKILL.md content for the user's skill, follow these principles:

Conciseness first: Only include information the agent wouldn't already know. Every paragraph must justify its token cost. Avoid explaining what common tools do — just say how to use them.

Progressive disclosure: Put essential step-by-step instructions in SKILL.md. Detailed API references, extensive examples, or supplementary docs go in separate files (reference.md, examples.md) linked from SKILL.md. Keep references one level deep.

Match freedom to fragility:

High freedom (text guidelines) — multiple valid approaches (e.g., content review, creative writing)
Medium freedom (templates/outlines) — preferred pattern with acceptable variation (e.g., report generation)
Low freedom (exact scripts/steps) — consistency is critical (e.g., data pipelines, image specs)

Skill Content Patterns

Select the best pattern based on what the skill does. Combine patterns as needed — most skills benefit from Workflow + Template.

Template Pattern — skill produces structured output:

## Output format
# [Title]
## Summary: [one-paragraph overview]
## Details: [structured content]

Workflow Pattern — skill follows sequential steps:

## Process
Step 1: [Action] — [what to do and why]
Step 2: [Action] — [what to do and why]
Step 3: [Action] — [what to do and why]

Conditional Pattern — skill handles different scenarios:

## Determine the approach
**Scenario A?** → Follow "Approach A"
**Scenario B?** → Follow "Approach B"

Examples Pattern — output quality depends on seeing examples:

## Examples
**Input:** [sample input]
**Output:** [expected output]

Feedback Loop Pattern — quality verification is needed:

## Process
1. Generate the output
2. Validate the result
3. If issues found → fix and re-validate
4. Only proceed when validation passes
