An official Anthropic Academy certification for completing the Claude Code in Action course — all 21 lessons finished. The course covered Claude Code end to end: setup and project configuration, managing and controlling context, custom commands, MCP server integration, and GitHub workflows, then deeper material on hooks — defining and implementing them and the gotchas around them — and the Claude Code SDK.
The practical takeaways (context management, custom-command automation, MCP integration, and hook-driven workflows) are the same techniques I apply when building production tooling with Claude Code. The certificate is verifiable via the linked credential.
