Skill Prompt Generator

Name: Skill Prompt Generator (Claude Skill)
Author: huangserva

by huangserva · huangserva/skill-prompt-generator

Generate consistent AI-portrait prompts — extracts features from a reference and emits style-locked prompts for downstream image models.

A skill that turns a reference description or image into reusable portrait prompts. Useful for content creators needing the same character across many generations.

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "skill-prompt-generator": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangserva/skill-prompt-generator"
      ],
      "_inferred": true
    }
  }
}

Open Claude Desktop → Settings → Developer → Edit Config. Restart after saving.

    "skill-prompt-generator": {
      "command": "git",

  }
}

Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

VS Code → Cline → MCP Servers → Edit

  "mcpServers": {
    "skill-prompt-generator": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangserva/skill-prompt-generator"
      ],
      "_inferred": true
    }
  }
}

Click the MCP Servers icon in the Cline sidebar, then "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "skill-prompt-generator": {
      "command": "git",
      "args": [

        "https://github.com/huangserva/skill-prompt-generator"
      ],
      "_inferred": true
    }
  }
}

Same shape as Claude Desktop. Restart Windsurf to pick up changes.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "skill-prompt-generator",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/huangserva/skill-prompt-generator"
      ]
    }
  ]
}

Continue uses an array of server objects rather than a map.

~/.config/zed/settings.json

{
  "context_servers": {
    "skill-prompt-generator": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/huangserva/skill-prompt-generator"
        ]
      }
    }
  }
}

Add to context_servers. Zed hot-reloads on save.

claude mcp add skill-prompt-generator -- git clone https://github.com/huangserva/skill-prompt-generator

One-liner. Verify with claude mcp list. Remove with claude mcp remove.

Use Cases

Real-world ways to use Skill Prompt Generator

Keep a character consistent across generations

👤 Claude Code users ⏱ ~15 min intermediate

When to use: You're running a comic / story and need same-character images.

Flow

Anchor

Provide the reference; skill extracts features.✓ Copied

→ Feature card
Generate variants

Request pose / lighting variants — feature card pinned.✓ Copied

→ Consistent character
Save

Persist the card for next time.✓ Copied

→ Reusable identity

Outcome: Character stays recognizable across prompts.

Combinations

Pair with other MCPs for X10 leverage

skill-prompt-generator + filesystem

Persist character cards next to your project

Combine skill-prompt-generator with filesystem: Persist character cards next to your project✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
extract / generate / save	(see docs)	Three-phase workflow	1 call

Cost & Limits

What this costs to run

API quota: N/A
Tokens per call: Small per call
Monetary: Free; image generation costs separate
Tip: Reuse character cards — re-extraction is wasteful

Security

Permissions, secrets, blast radius

Minimum scopes: fs-read fs-write

Credential storage: Card files on disk

Data egress: None by itself

Troubleshooting

Common errors and fixes

Variants drift

Card weights too loose — increase identity-lock strength
