Knowledge Manager Setup

Automated setup wizard that configures MCP servers and creates configuration files

Overview

This skill automates the Knowledge Manager setup process:

• Detects your environment (Antigravity, Claude Code, etc.)

• Asks for your preferences (Obsidian vault path, etc.)

• Automatically configures MCP servers

• Creates km-config.json

• Verifies the setup

Setup Flow

Step 1: Environment Detection

function detect_environment() { // Check for Antigravity if (file_exists("~/.gemini/antigravity/mcp_config.json")) { return "antigravity" }

// Check for Claude Code if (command_exists("claude")) { return "claude-code" }

return "unknown" }

Step 2: User Preferences

Ask the user:

================================================= Knowledge Manager Setup Wizard

Where would you like to save your notes?

[1] Obsidian (Recommended for personal knowledge management) [2] Local Markdown files only [3] Both Obsidian and local backup

Selection: _

If Obsidian selected:

Please provide your Obsidian vault path:

Examples: Windows: C:/Users/YourName/Documents/MyVault Mac: /Users/YourName/Documents/MyVault Linux: /home/yourname/Documents/MyVault

Vault path: _

Step 3: MCP Server Configuration

For Antigravity (Simplified!)

Antigravity has a built-in browser agent, so playwright MCP is optional. Only Obsidian MCP is required if you want to save to Obsidian.

Config file location: ~/.gemini/antigravity/mcp_config.json

function configure_antigravity_mcp(vaultPath, options = {}) { // 1. Read existing config configPath = expand_path("~/.gemini/antigravity/mcp_config.json") existingConfig = Read(configPath) || { "mcpServers": {} }

// 2. Add required servers (Obsidian only for Antigravity) newServers = { "obsidian": { "command": "npx", "args": ["-y", "@huangyihe/obsidian-mcp"], "env": { "OBSIDIAN_VAULT_PATH": vaultPath } } }

// 3. Optionally add Playwright (for screenshots, batch processing, etc.) if (options.includePlaywright) { newServers["playwright"] = { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-playwright"] } }

// 4. Merge with existing existingConfig.mcpServers = { ...existingConfig.mcpServers, ...newServers }

// 5. Write back Write(configPath, JSON.stringify(existingConfig, null, 2))

return true }

Antigravity Browser Options

Ask the user (only in Antigravity):

================================================= Browser Configuration

Antigravity has a powerful built-in browser agent. For most use cases, you don't need additional browser tools.

Do you want to add Playwright MCP? (optional)

[1] No, use Antigravity's built-in browser (Recommended) [2] Yes, add Playwright for advanced features (screenshots, batch processing, DOM manipulation)

Selection: _

For Claude Code

Claude Code doesn't have a built-in browser, so Playwright is required.

function configure_claude_mcp(vaultPath) { // Use claude mcp add command Bash(claude mcp add playwright -s user -- npx -y @modelcontextprotocol/server-playwright)

Bash(claude mcp add obsidian -s user -e OBSIDIAN_VAULT_PATH="${vaultPath}" -- npx -y @huangyihe/obsidian-mcp)

return true }

Step 4: Create km-config.json

function create_km_config(options) { config = { "storage": { "primary": options.storage || "obsidian", "obsidian": { "enabled": options.obsidianEnabled || true, "vaultPath": options.vaultPath, "defaultFolder": "Zettelkasten" }, "local": { "enabled": options.localEnabled || true, "outputPath": "./km-notes" } }, "browser": { // Antigravity uses native browser by default "provider": options.environment === "antigravity" ? "antigravity" : "playwright" }, "defaults": { "detailLevel": 2 } }

Write("km-config.json", JSON.stringify(config, null, 2)) }

Step 5: Verification & Next Steps

For Antigravity

================================================= Setup Complete!

Configuration files created: [OK] ~/.gemini/antigravity/mcp_config.json (updated) [OK] ./km-config.json (created)

MCP servers configured: [OK] obsidian - For saving notes to your vault

Browser configuration: [OK] Using Antigravity's built-in browser agent (No additional MCP needed!)

IMPORTANT: To activate the MCP servers:

1. Open Antigravity
2. Click the Agent panel
3. Click [...] (three dots) > MCP Servers
4. Click "Manage MCP Servers"
5. Click "Refresh"
6. Verify that "obsidian" appears in the list

You can now use Knowledge Manager:

"이 페이지를 정리해줘: https://example.com/article" "Process this article: https://example.com/article"

=================================================

For Claude Code

================================================= Setup Complete!

Configuration: [OK] MCP servers added (playwright, obsidian) [OK] ./km-config.json created

You can now use Knowledge Manager:

/knowledge-manager https://example.com/article

=================================================

Troubleshooting

MCP Server Not Appearing (Antigravity)

Check config file syntax:

cat ~/.gemini/antigravity/mcp_config.json | python -m json.tool

Restart Antigravity completely (not just refresh)

Check for conflicting server names

Permission Errors

If you see permission errors when writing to config:

The setup wizard couldn't write to the config file automatically.

Please manually add this to your mcp_config.json:

{config content here}

File location: ~/.gemini/antigravity/mcp_config.json

Environment-Specific Notes

Windows Paths

Use forward slashes in config files:

"vaultPath": "C:/Users/YourName/Documents/MyVault"

Mac/Linux Paths

Standard Unix paths work:

"vaultPath": "/Users/yourname/Documents/MyVault"

OneDrive/Cloud Sync

Cloud-synced vaults work fine:

"vaultPath": "C:/Users/YourName/OneDrive/Documents/MyVault"
