Add Catnip Feature

This PR adds the Catnip feature to your devcontainer configuration.

Catnip enables agentic coding made fun and productive, accessible from your mobile device.

Changes

• Created .devcontainer/devcontainer.json to include the Catnip feature
• Using minimal Ubuntu base image to avoid disk space issues (you can customize the image if needed)

Next Steps

1. Review and merge this PR
2. Create a new codespace from this branch or restart your existing codespace
3. Open the Catnip mobile app to connect

Customization

If you need specific development tools, you can change the base image in .devcontainer/devcontainer.json to:

• mcr.microsoft.com/devcontainers/python:3.12 for Python development
• mcr.microsoft.com/devcontainers/javascript-node:20 for Node.js development
• Or any other devcontainer image

Provide Node toolchain in devcontainer

The new devcontainer uses the minimal mcr.microsoft.com/devcontainers/base:ubuntu image and only installs the Catnip feature, so Codespaces/Dev Container builds for this Astro/npm repo will start without Node or npm. Anyone opening the repo in that container will hit immediate failures running npm install or npm run dev until they manually install a Node runtime, whereas Codespaces previously defaulted to a Node-capable image. Please add a Node feature/image so the development environment matches the project requirements.

PR Review: Add Catnip Feature

Overview

This PR adds a devcontainer configuration to enable Catnip for mobile-based development. The change is minimal, adding a single .devcontainer/devcontainer.json file.

🔍 Code Quality Assessment

Configuration Structure: ✅ Good

• Valid JSON format
• Clean, minimal configuration
• Follows devcontainer specification

---

⚠️ Key Concerns & Recommendations

1. Base Image Mismatch - 🔴 Critical

The PR uses mcr.microsoft.com/devcontainers/base:ubuntu which is a minimal Ubuntu image without the Node.js toolchain required by this project.

Issue: This project is an Astro/Node.js site that requires:

• Node.js 20 (per .github/workflows/build.yml:31)
• npm with specific dependencies
• Rust toolchain + trop CLI (for dev server management)

Impact: Developers opening this devcontainer will not be able to:

• Run just install (npm unavailable)
• Run just preview (Node.js + trop unavailable)
• Build the site (npm run build will fail)

Recommendation: Change to a Node.js-based image:

{
  "name": "Development Container",
  "image": "mcr.microsoft.com/devcontainers/javascript-node:20",
  "features": {
    "ghcr.io/wandb/catnip/feature:1": {},
    "ghcr.io/devcontainers/features/rust:1": {
      "version": "stable"
    }
  },
  "postCreateCommand": "cargo install trop-cli --locked && npm ci",
  "forwardPorts": [6369]
}

2. Missing Project Tooling - 🟡 Important

The current configuration doesn't install critical project dependencies:

• just: Command runner used extensively (see justfile)
• trop: Port management tool for dev server
• npm dependencies: Not automatically installed

Recommendation: Add a postCreateCommand to set up the environment

3. Port Documentation - 🟡 Minor

Port 6369 is forwarded but not documented. Based on the Catnip feature, this appears to be for mobile app connectivity.

4. Lack of Testing/Validation - 🟡 Important

The PR doesn't indicate whether the devcontainer was tested with the actual project workflow.

Recommendation: Before merging, verify that:

• just install works in the devcontainer
• just preview successfully starts the dev server
• just build completes successfully
• just lint runs without issues
• Catnip mobile app can connect properly

5. CI/CD Workflow Consideration - ℹ️ Info

The project has comprehensive CI workflows that use specific versions and tools that should match the dev environment.

---

🔒 Security Assessment

✅ No security concerns identified

• Using official Microsoft devcontainer images
• Catnip feature from official source (wandb)
• No sensitive data or credentials in configuration
• Port forwarding is appropriate for development

---

🎯 Performance Considerations

Build Time: ⚠️ Devcontainers can have long initial build times

• The minimal Ubuntu image requires installing all tooling from scratch
• Consider pre-built images to improve developer experience

Resource Usage: ✅ Minimal configuration should be lightweight

---

📋 Test Coverage

❌ No tests included - This is a configuration change, but validation steps should be documented or automated.

---

🎨 Style & Conventions

Based on CLAUDE.md and repository patterns:

• ✅ Configuration follows standard devcontainer format
• ⚠️ Should align with project's emphasis on using just commands
• ⚠️ Missing integration with repository's existing tooling (justfile)

---

💡 Additional Recommendations

1. Documentation: Add a section to CLAUDE.md or README about using devcontainers for development
2. Consistency: Ensure devcontainer Node.js version matches CI (Node 20)
3. Optional Features: Consider adding helpful devcontainer features:
   • github-cli (gh) - already used in project
   • Editor extensions for Astro, Tailwind, MDX

---

✅ Summary

Verdict: ⚠️ Needs Changes Before Merge

The PR is a good addition for mobile development support, but the current configuration won't work with the project's requirements. The base image needs to include Node.js 20 and the Rust toolchain, and dependencies should be installed automatically.

Suggested Action Items:

1. Switch to javascript-node:20 base image
2. Add Rust feature and install trop
3. Add postCreateCommand to install npm dependencies
4. Test the complete development workflow in the devcontainer
5. Document the new development option

Priority: Fix the base image issue (Critical) before merging.
