Devcontainer Setup Skill workflow skill. Use this skill when the user needs Creates devcontainers with Claude Code, language-specific tooling (Python/Node/Rust/Go), and persistent volumes. Use when adding devcontainer support to a project, setting up isolated development environments, or configuring sandboxed Claude Code workspaces and the operator should preserve the upstream workflow, copied support files, and provenance before merging or handing off.

This public intake copy packages plugins/antigravity-awesome-skills-claude/skills/devcontainer-setup from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.
Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.
This intake keeps the copied upstream files intact and uses metadata.json plus ORIGIN.md as the provenance anchor for review.
Devcontainer Setup Skill Creates a pre-configured devcontainer with Claude Code and language-specific tooling.
Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Phase 1: Project Reconnaissance, Phase 2: Generate Configuration, Base Template Features, Language-Specific Sections, Adding Persistent Volumes, Output Files.
When to Use This Skill
Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.
User asks to "set up a devcontainer" or "add devcontainer support"
User wants a sandboxed Claude Code development environment
User needs isolated development environments with persistent configuration
User already has a devcontainer configuration and just needs modifications
User is asking about general Docker or container questions
User wants to deploy production containers (this is for development only)
Operating Table
Situation
Start here
Why it matters
First-time use
metadata.json
Confirms repository, branch, commit, and imported path before touching the copied workflow
Provenance review
ORIGIN.md
Gives reviewers a plain-language audit trail for the imported source
Workflow execution
SKILL.md
Starts with the smallest copied file that materially changes execution
Supporting context
SKILL.md
Adds the next most relevant copied source file without loading the entire package
Handoff decision

Workflow
This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.
For multi-language postCreateCommand, chain all setup commands:
uv run /opt/post_install.py && uv sync && npm ci
Extensions and settings from all detected languages should be merged into the configuration.
Examples
Example 1: Ask for the upstream workflow directly
Use @devcontainer-setup to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.
Example 2: Ask for a provenance-grounded review
Review @devcontainer-setup against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.
Example 3: Narrow the copied support files before execution
Use @devcontainer-setup for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.
Example 4: Build a reviewer packet
Review @devcontainer-setup using the copied upstream files plus provenance, then summarize any gaps before merge.
Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.
Best Practices
Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.
Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
Treat generated examples as scaffolding; adapt them to the concrete task before execution.
Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.
Troubleshooting
Problem: The operator skipped the imported context and answered too generically
Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills-claude/skills/devcontainer-setup, fails to mention provenance, or does not use any copied source files at all.
Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Load only the files that materially change the answer, then restate the provenance before continuing.
Problem: The imported workflow feels incomplete during review
Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task.
Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.
Problem: The task drifted into a different specialization
Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported: Phase 2: Generate Configuration
Start with base templates from resources/ directory. Substitute:
{{PROJECT_NAME}} → Human-readable name (e.g., "My Project")
{{PROJECT_SLUG}} → Slug for volumes (e.g., "my-project")
Then apply language-specific modifications below.
Imported: Base Template Features
The base template includes:
Claude Code with marketplace plugins (anthropics/skills, trailofbits/skills, trailofbits/skills-curated)
Python 3.13 via uv (fast binary download)
Node 22 via fnm (Fast Node Manager)
ast-grep for AST-based code search
Network isolation tools (iptables, ipset) with NET_ADMIN capability
Modern CLI tools: ripgrep, fd, fzf, tmux, git-delta
Imported: Language-Specific Sections
Python Projects
Detection:pyproject.toml, requirements.txt, setup.py, or *.py files
Dockerfile additions:
The base Dockerfile already includes Python 3.13 via uv. If a different version is required (detected from pyproject.toml), modify the Python installation:
# Install Python via uv (fast binary download, not source compilation)
RUN uv python install <version> --default
