generate-gitignore-by-techstack

What problem does it solve?

Automates creating or updating a project's .gitignore by detecting the repository's technology stack and combining official github/gitignore templates while preserving any existing custom rules.

Core Features & Use Cases

• Automatic tech detection: Scans files like package.json, go.mod, *.csproj, Dockerfile, and IDE folders to infer relevant templates.
• Template download and merge: Fetches templates from github/gitignore, groups them by technology, removes duplicates, and appends well-labeled sections.
• Safe update mode: Reads existing .gitignore, preserves user-defined sections, and appends missing rules instead of overwriting.
• Use Case: Initialize a new repository or update an evolving codebase when adding languages or tools so the .gitignore stays comprehensive and non-destructive.

Quick Start

Run the generate-gitignore-by-techstack skill to scan the repository, fetch matching templates from GitHub, and create or update the .gitignore while preserving existing custom sections.
