.devfile.yaml (1)

57-62: Pin Claude Code to a tested version to keep workspace setup reproducible.

Line 62 installs a mutable latest version (npm install -g @anthropic-ai/claude-code``). This can introduce unpredictable breakages across developer workspaces. The package is actively maintained (latest: 2.1.100, Node >=18.0.0), so pinning to a specific tested version ensures consistent setup across the team.

🔧 Suggested change

-      commandLine: "npm install -g `@anthropic-ai/claude-code`"
+      commandLine: "npm install -g `@anthropic-ai/claude-code`@2.1.100"

Alternatively, use an environment variable for flexibility:

-      commandLine: "npm install -g `@anthropic-ai/claude-code`"
+      commandLine: "npm install -g `@anthropic-ai/claude-code`@${CLAUDE_CODE_VERSION:-2.1.100}"
