Container Layer
Build a reproducible, cached environment overlay for ephemeral containers using a Dockerfile-like spec.
Concept
The container resets every session, but your environment shouldn't. This skill:
- Parses a
Containerfile(Dockerfile subset) that declares your environment - Caches the built result as a tarball in GitHub Releases
- Restores from cache on subsequent boots (single fetch vs. N installs)
- Provides a
uvshim that captures ad-hoc installs back into the Containerfile
Supported Containerfile Instructions
# Environment variables
ENV KEY=value
# Shell commands (including package installs)

68mapping-codebases
Generate navigable code maps for unfamiliar codebases. Extracts exports/imports via AST (tree-sitter) to create _MAP.md files per directory showing classes, functions, methods with signatures and line numbers. Use when exploring repositories, understanding project structure, analyzing unfamiliar code, or before modifications. Triggers on "map this codebase", "explore repo", "understand structure", "what does this project contain", or when starting work on an unfamiliar repository.
54accessing-github-repos
GitHub repository access in containerized environments using REST API and credential detection. Use when git clone fails, or when accessing private repos/writing files via API.
48asking-questions
Guidance for asking clarifying questions when user requests are ambiguous, have multiple valid approaches, or require critical decisions. Use when implementation choices exist that could significantly affect outcomes.
