Terraphim Package Manager Replacement

This skill uses Terraphim's knowledge graph to automatically replace package manager commands with preferred alternatives (e.g., npm → bun).

When to Use This Skill

Activate this skill when:

• User mentions npm, yarn, or pnpm commands
• User asks to install dependencies
• User shares package.json scripts
• User provides shell scripts with package manager commands
• User discusses build/test/dev commands

How It Works

The skill uses terraphim-tui replace command which:

1. Loads a knowledge graph from markdown files
2. Uses Aho-Corasick automata for fast pattern matching
3. Replaces all package manager references with bun
4. Preserves the rest of the text unchanged

Capabilities

Supported Replacements:

• npm → bun
• yarn → bun
• pnpm → bun
• npm install → bun install
• yarn install → bun install
• pnpm install → bun install

Features:

• Case-insensitive matching (NPM = npm)
• Longest match first (npm install before npm)
• Sub-100ms execution time
• Non-overlapping replacements

Instructions

Step 1: Check if terraphim-tui is available

Before using this skill, verify terraphim-tui is built:

ls -lh target/release/terraphim-tui

If not found, build it:

cargo build --release -p terraphim_tui

Step 2: Identify package manager commands

Look for patterns like:

• "npm install"
• "yarn build"
• "pnpm test"
• package.json scripts with npm/yarn/pnpm

Step 3: Replace using terraphim-tui

Use the replace command:

terraphim-tui replace "TEXT_TO_REPLACE" 2>/dev/null

Important: Suppress stderr with 2>/dev/null to avoid log messages.

Step 4: Present the results

Show the user:

1. Original text
2. Replaced text
3. Brief explanation of what changed

Examples

Example 1: Simple Command Replacement

User asks: "How do I install dependencies?"

Before replacement:

npm install

After replacement:

bun install

Your response:

To install dependencies with bun:

\`\`\`bash
bun install
\`\`\`

I've replaced `npm install` with `bun install` using Terraphim's knowledge graph.

Example 2: Package.json Scripts

User shares:

{
  "scripts": {
    "install": "npm install",
    "build": "yarn build",
    "test": "pnpm test"
  }
}

After replacement:

{
  "scripts": {
    "install": "bun install",
    "build": "bun build",
    "test": "bun test"
  }
}

Example 3: Shell Script

User provides:

#!/bin/bash
npm install
npm run build
npm test

After replacement:

#!/bin/bash
bun install
bun run build
bun test

Best Practices

1. Always explain the replacement: Don't silently change commands without telling the user
2. Show before and after: Let users see what was changed
3. Respect user preferences: If user explicitly wants npm, don't override
4. Handle errors gracefully: If terraphim-tui fails, provide the original text
5. Suppress logs: Always use 2>/dev/null to avoid log clutter

Error Handling

If terraphim-tui is not available:

1. Inform the user
2. Provide manual replacement guidance
3. Suggest building terraphim-tui

Example error response:

I don't have terraphim-tui available to perform automatic replacement.
To use bun instead of npm, manually replace:
- npm → bun
- npm install → bun install
- npm run → bun run

Integration with Knowledge Graph

This skill leverages Terraphim's knowledge graph system defined in:

• docs/src/kg/bun.md: Package manager synonyms
• docs/src/kg/bun_install.md: Install command synonyms

These markdown files define semantic relationships that power the replacement logic.

Performance Notes

• Pattern matching: ~10-50ms
• Knowledge graph loading: ~100-200ms (cached after first run)
• Total execution: typically under 100ms

Related Commands

# Replace text
terraphim-tui replace "TEXT" 2>/dev/null

# Replace with role
terraphim-tui replace "TEXT" --role "Terraphim Engineer" 2>/dev/null

# Replace with output format
terraphim-tui replace "TEXT" --format markdown 2>/dev/null

Limitations

• Requires terraphim-tui to be built
• Works best with specific command patterns
• May be aggressive with longer text containing many technical terms
• Requires knowledge graph files in docs/src/kg/
