Doctor

Run a health check on the project environment. Report what's working and what needs attention.

Instructions

Run each check below and report results using this format:

## Project Health Check

| Check | Status | Details |
|-------|--------|---------|
| Git repo | ✅ | On branch main, 12 commits |
| Language env | ⚠️ | Python 3.12 found, but no .venv active |
| Dependencies | ❌ | Not installed — run `pip install -e '.[dev]'` |
| ...  | ... | ... |

Checks to Run

1. Git

• Is this a git repo? (git rev-parse --is-inside-work-tree)
• Current branch and commit count
• Any uncommitted changes? (git status --porcelain)
• Is a remote configured? (git remote -v)

2. Language Environment

Detect language from config files (pyproject.toml, package.json, go.mod, Cargo.toml):

• Python: Is Python installed? What version? Is a virtual environment active? ($VIRTUAL_ENV)
• TypeScript: Is Node.js installed? What version? Is node_modules/ present?
• Go: Is Go installed? What version?
• Rust: Is Rust installed? What version? (rustc --version)

3. Dependencies

• Are project dependencies installed?
  • Python: pip list shows project package
  • TypeScript: node_modules/ exists and package-lock.json matches
  • Go: go.sum exists
  • Rust: Cargo.lock exists

4. Development Tools

• Linter available? (ruff, eslint, golangci-lint, clippy)
• Formatter available? (ruff, eslint, gofmt, rustfmt)
• Type checker available? (mypy, tsc, built-in)
• make available?
• pre-commit installed? Hooks active? (pre-commit --version, .git/hooks/pre-commit)

5. Claude Code

• .claude/settings.json exists?
• .claude/skills/ directory has skills?
• CLAUDE.md exists?
• tasks/todo.md exists?

6. GitHub Integration

• gh CLI installed? (which gh)
• gh authenticated? (gh auth status)
• Issue labels created? (check with gh label list if authenticated)

7. Tests

• Does make test-unit work? (run it, report pass/fail)
• If it fails, show the error summary (not full output)

After the Check

1. Summarize: "X of Y checks passed"
2. For any failures, show the exact command to fix it
3. If everything passes: "Project is healthy — ready to build."

Rules

• Run checks quickly — skip anything that would take >10 seconds
• Don't install anything automatically — just report what's missing and how to fix it
• If make test-unit has no tests yet, report as ⚠️ (warning), not ❌ (failure)
• Group related issues together (e.g., "venv not active" and "deps not installed" are the same root cause)
