SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automates the end-to-end creation of Dalec specification files from GitHub repositories by providing a reproducible, deterministic workflow that converts repo contents into validated Dalec YAML specs.

Core Features & Use Cases

  • Deterministic discovery of build files (Dockerfile and Makefile) across a repository, with a fresh result directory for each run.
  • Automated extraction of non-deterministic values and generation of a complete Dalec spec via a CLI, enabling repeatable builds for container and package workflows.
  • Suitable for monorepos and multi-path repositories where build files live in subdirectories, with outputs organized under result/{repo}/.
  • Use Case: A developer wants to convert a GitHub project into a published Dalec spec to enable automated container builds and packaging.

Quick Start

Run the three-step workflow: discover build files, download them, then generate the Dalec spec YAML.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate Dalec specs from a GitHub repository automatically?▼

To generate Dalec specs automatically, this Skill discovers Dockerfile and Makefile build configurations in a GitHub repository, extracts non-deterministic values, and outputs a validated Dalec YAML file for container builds.

What is a deterministic Dalec specification file used for?▼

A deterministic Dalec specification file provides a reproducible YAML configuration that defines how a software project's Dockerfile and Makefile-based build should be executed for container builds and packaging workflows.

Can I generate Dalec specs for monorepos where build files are in subdirectories?▼

Yes, you can generate Dalec specs for monorepos. The workflow deterministically discovers build files across multiple repository paths and organizes the resulting YAML outputs under dedicated repository-specific result directories.

How do I convert a Dockerfile and Makefile project into a container build configuration?▼

Converting a Dockerfile and Makefile project requires discovering the build files, downloading repository contents, and executing a CLI that extracts non-deterministic values to produce a complete Dalec spec YAML configuration.

What are the limitations of generating Dalec specs from GitHub repositories?▼

The main limitation is that Dalec spec generation primarily targets software projects using Dockerfile and Makefile-based build configurations, meaning repositories relying on other build systems may not be fully supported.

Why does my generated Dalec YAML spec need to extract non-deterministic values?▼

Extracting non-deterministic values is required to produce a deterministic Dalec YAML spec, ensuring that your container builds remain reproducible and repeatable across different automated build environments.
