StructKit

YAML scaffolding your AI assistant can actually run.

Define a repo once (files, CI, Terraform, app layout). Generate it from the CLI, from CI, or through an assistant over MCP. When the org template on GitHub changes, the next generate picks it up. No golden repo. No separate Cookiecutter tree.

Try it in 60 seconds

# Install the CLI
pip install structkit

# Preview available bundled structures
structkit list

# Generate a ready-made Terraform module scaffold
structkit generate --vars module_name=my-terraform-module terraform/modules/generic ./my-terraform-module

# Start MCP server for AI integration
structkit mcp --server

Prefer Docker?

docker run --rm -v "$(pwd):/workdir" ghcr.io/httpdss/structkit:main \
  generate --vars module_name=my-terraform-module terraform/modules/generic ./my-terraform-module

Ecosystem

These are install paths for StructKit, not separate products. Star this repo.

• structkit-setup — install StructKit on PATH in GitHub Actions (httpdss/structkit-setup@v0), then run any structkit command
• GitHub Action — validate, generate, or drift-check in CI (httpdss/structkit-setup@v0, then httpdss/structkit-action@v0)
• VS Code / Cursor — schema and autocomplete for .structkit.yaml
• Agent skills — inspect, preview, generate, validate from an assistant
• pre-commit — validate structures before they land
• Homebrew — brew install httpdss/structkit/structkit
• Linux .deb / .rpm — download from the GitHub release (attached from 3.3.1 on), or build locally per packaging/README.md
• Backstage — scaffolder actions for platform teams
• Hermes plugin — safe StructKit tools inside Hermes

👤 Who StructKit is for

• Platform / DevEx teams standardizing service layouts, CI baselines, and engineering conventions across many repos.
• DevOps engineers generating repeatable Terraform modules, Kubernetes manifests, GitHub Actions workflows, and config bundles.
• AI coding workflow users who want assistants to scaffold from approved templates instead of inventing project structure.
• Individual developers tired of rebuilding the same files, folders, and docs for every new project.

🤔 Why StructKit?

Project scaffolding tools exist in most ecosystems, but StructKit solves problems the others often leave to copy-paste, template repositories, or custom scripts.

Feature	cookiecutter	copier	StructKit
Remote content (GitHub, S3, GCS, HTTP)	❌	❌	✅
AI / MCP integration	❌	❌	✅
Pre/post generation hooks	✅	✅	✅
Dry run mode	❌	✅	✅
YAML-first (no template repo required)	❌	❌	✅
Multiple file conflict strategies	❌	✅	✅
IDE schema validation	❌	❌	✅

Key differentiators:

• Remote-first content: Reference your organization's canonical CI template from GitHub directly in your StructKit config. When the template updates, all new projects get the update — no copy-paste maintenance.
• AI-native via MCP: Start the StructKit MCP server so your AI assistant can generate project scaffolds from natural language using your templates as the source of truth.
• Agent skill ready: Install the companion httpdss/structkit-skills workflow skill so AI assistants consistently inspect, preview, generate, and validate StructKit structures.
• YAML-first: Define structures directly in YAML. No separate template repository is required.
• Safe by default: Use dry-run previews and file conflict strategies before writing into existing projects.

✨ Key Features

• 📝 YAML-Based Configuration - Define project structures in simple, readable YAML
• 🔧 Template Variables - Dynamic content with Jinja2 templating and interactive prompts
• 🌐 Remote Content - Fetch files from GitHub, HTTP/HTTPS, S3, and Google Cloud Storage
• 🛡️ Smart File Handling - Multiple strategies for managing existing files (overwrite, skip, backup, etc.)
• 🪝 Automation Hooks - Pre and post-generation shell commands
• 🔒 Hook Safety - Skip hooks (--no-hooks / STRUCTKIT_NO_HOOKS), confirm interactively, or restrict commands with an allowlist
• ⚙️ Config Layering - Merge built-in defaults, ~/.config/struct/config.yaml, optional --config-file, and CLI flags
• 🎯 Dry Run Mode - Preview changes before applying them
• ✅ Validation & Schema - Built-in YAML validation and IDE support
• 🤖 MCP Integration - Model Context Protocol support for AI-assisted development workflows
