cfg-diff

Config Diff

Compare and merge configuration files.

Capabilities

• Diff: Side-by-side or unified diff of config files
• Semantic Diff: Understand structure (not just text) for YAML/JSON/TOML
• Merge Suggestions: Propose how to merge conflicting configs
• Format Support: YAML, JSON, TOML, INI, env files

Usage

Ask the agent to:

• "Compare config.yml and config.production.yml"
• "What changed between these two JSON configs?"
• "Help me merge these two TOML files"
• "Show differences between .env.local and .env.production"

How It Works

Uses diff, jq, yq, and text analysis:

diff --unified config-a.yml config-b.yml
jq -S . a.json > /tmp/a.json && jq -S . b.json > /tmp/b.json && diff /tmp/a.json /tmp/b.json

Requirements

• diff (pre-installed)
• Optional: jq for JSON, yq for YAML
• No API keys needed
