SuperFlag

⚠️ MIGRATION NOTICE: If you previously installed context-engine-mcp, please uninstall it and install superflag instead:

pip uninstall context-engine-mcp
pip install superflag

Note: This project was inspired by the pioneering work in SuperClaude Framework and SuperGemini Framework. Special thanks to SuperClaude-Org team members @NomenAK and @mithun50 whose work made this possible.

SuperFlag provides 18 contextual flags that guide assistant behavior (e.g., --strict, --auto). It exposes an MCP stdio server and small setup helpers for common clients.

Quick Start

# Install
pip install superflag

# Interactive installation (choose platforms)
superflag install

# Direct installation
superflag install --target claude-code  # Claude Code only
superflag install --target gemini-cli   # Gemini CLI only
superflag install --target cn           # Continue only

Then in your client/assistant, use prompts with flags:

• "Fix this bug --auto" (auto-select flags)
• "--save" (handoff documentation)
• "Analyze --strict" (precise, zero-tolerance mode)

18 Flags

Installation

Claude Code

# Install package
pip install superflag

# Install configuration files (automatic MCP registration)
superflag install

Continue Extension

# Install package
pip install superflag

# Install configuration files
superflag install --target cn

Edit ~/.continue/mcpServers/superflag.yaml:

# Standard Python (most common)
name: SuperFlag
command: python
args: ["-m", "superflag"]

# Or use absolute path to specific environment
# name: SuperFlag
# command: /path/to/venv/bin/python
# args: ["-m", "superflag"]

Restart VS Code, then type @ in Continue chat to access MCP tools.

Gemini CLI

# Install package
pip install superflag

# Install configuration files for Gemini CLI
superflag install --target gemini-cli

This command:

• Appends @SUPERFLAG.md to ~/.gemini/GEMINI.md (adds once; no duplicate)
• Writes latest instructions to ~/.gemini/SUPERFLAG.md

Register the MCP stdio command in Gemini CLI settings:

• Command: python -m superflag
• Args: []
• Transport: stdio

MCP registration (example)

• File: ~/.gemini/settings.json
• Add or merge this into the mcpServers section:

{
  "mcpServers": {
    "superflag": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "superflag"],
      "env": {}
    }
  }
}

Gemini CLI settings

• Location: ~/.gemini/settings.json
• Structure:

{
  "mcpServers": {
    "<server-name>": {
      "type": "stdio",
      "command": "<executable or interpreter>",
      "args": ["<arg1>", "<arg2>", "..."],
      "env": { "ENV_KEY": "value" }
    }
  }
}

Common setups

• pip (python -m):

{
  "mcpServers": {
    "superflag": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "superflag"],
      "env": {}
    }
  }
}

• venv absolute path (Windows):

{
  "mcpServers": {
    "superflag": {
      "type": "stdio",
      "command": "C:\\path\\to\\venv\\Scripts\\superflag.exe",
      "args": [],
      "env": {}
    }
  }
}

• venv with interpreter (module run):

{
  "mcpServers": {
    "superflag": {
      "type": "stdio",
      "command": "/path/to/venv/bin/python",
      "args": ["-m", "superflag"],
      "env": {}
    }
  }
}

Notes

• type is stdio.
• If the command is not on PATH, use an absolute path (escape backslashes on Windows).
• After editing, restart Gemini CLI and verify tools (e.g., list_available_flags).

Usage

In Chat

# Auto mode - AI selects flags
"Refactor this code --auto"

# Direct flags
"--save"  # Creates handoff doc
"--analyze --strict"  # Multi-angle analysis with zero errors
"--reset --analyze"  # Reset session and reapply

# Combined flags
"Review this --analyze --strict --seq"

MCP Tools

• get_directives(['--flag1', '--flag2']) - Activates flags

Development: use pip install -e . for editable installs.

Configuration updates: edit ~/.superflag/flags.yaml and restart the MCP server.

Optional MCP Servers

Additional MCP servers can complement certain flags:

For --seq flag:

# Sequential thinking server  
claude mcp add -s user -- sequential-thinking npx -y @modelcontextprotocol/server-sequential-thinking

These are optional; SuperFlag works without them.

Session

• Duplicate flags produce a brief reminder instead of repeating full directives.
• Use --reset when the task/context changes (resets all flag states to new).
• The server tracks active flags per session.
• Note: In Claude, flag states persist through /clear or /compact commands. Use --reset to reinitialize.

--auto

--auto instructs the assistant to analyze the task and pick appropriate flags (do not include --auto in get_directives calls).

Behavior

• --auto only: the assistant selects a full set of flags automatically.
• --auto --flag1 --flag2: the assistant applies --flag1, --flag2 and may add additional flags if helpful. User‑specified flags take priority when there is overlap or conflict.
• --flag1 --flag2 (without --auto): only the specified flags are applied.

Uninstallation

# Complete uninstall from all environments (Claude Code + Continue)
superflag uninstall

# Remove Python package
pip uninstall superflag

Note: During uninstallation, ~/.superflag/flags.yaml is backed up to ~/flags.yaml.backup_YYYYMMDD_HHMMSS before removal. During installation, existing flags.yaml is backed up and updated to the latest version.

Claude Code note: Uninstall removes the @SUPERFLAG.md reference from ~/.claude/CLAUDE.md, deletes ~/.claude/SUPERFLAG.md if present, removes the hook file from ~/.claude/hooks/superflag.py, and removes the hook registration from ~/.claude/settings.json.

Gemini CLI note: Uninstall removes the @SUPERFLAG.md reference from ~/.gemini/GEMINI.md and deletes ~/.gemini/SUPERFLAG.md if present.

Continue note: Uninstall removes the SuperFlag rules from ~/.continue/config.yaml (when present) and deletes ~/.continue/mcpServers/superflag.yaml if present.
