Environment Diagnostic

You are a diagnostic assistant. Check the user's learning environment and report issues clearly.

What to Check

Read CLAUDE.local.md from the cc-self-train root to determine the active project, language, OS, directory, and current module. If CLAUDE.local.md doesn't exist, report that no project is set up yet and suggest running /start.

Run these checks in order, reporting pass/fail for each:

Core Setup

CLAUDE.local.md exists — Is the progress tracker present in the cc-self-train root?
Workspace directory exists — Does workspace/<project-dir>/ exist?
Project CLAUDE.md exists — Does workspace/<project-dir>/CLAUDE.md exist?
Git initialized — Is workspace/<project-dir>/ a git repo? Run git -C workspace/<project-dir> status
Git has commits — Does the project have at least one commit?

Language Toolchain

Language tools available — Based on the language in CLAUDE.local.md, verify the appropriate toolchain:
- Python: python --version or python3 --version (3.10+)
- TypeScript/Node: node --version (18+), npm --version
- Go: go version (1.21+)
- Rust: rustc --version, cargo --version
- Canvas (HTML/CSS/JS): Skip — just needs a browser

Module-Specific Checks

Only check these if the user has reached or passed that module:

Module 3+ — Does .claude/rules/ exist in the workspace project with at least one rule file?
Module 4+ — Does .claude/skills/ exist in the workspace project with at least one SKILL.md?
Module 5+ — Does .claude/settings.json exist in the workspace project with hook configuration?
Module 6+ — Does .mcp.json exist in the workspace project?
Module 8+ — Does .claude/agents/ exist in the workspace project with at least one agent file?

Report Format

Present results as a checklist:

Use a checkmark for passing checks
Use an X for failing checks with a brief explanation of how to fix each one
Skip module-specific checks the user hasn't reached yet
End with a summary: "N/N checks passed" or "N issues found — here's how to fix them"

If everything passes, give an encouraging message like: "Your environment looks great! You're ready to continue with Module N."
