# ============================================================================
# ADK-FLUENT DEVELOPMENT WORKFLOW
# ============================================================================
#
#   just setup      → First-time setup: install deps + pre-commit hooks
#   just all        → Full pipeline: scan → seed → generate → docs
#   just scan       → Introspect installed ADK, produce manifest.json
#   just seed       → Generate seed.toml from manifest.json
#   just generate   → Combine seed.toml + manifest.json → code + stubs + tests + lint
#   just lint       → Run ruff check + format check (hand-written files only)
#   just fmt        → Auto-format hand-written files (ruff + mdformat)
#   just fmt-changed → Auto-format only changed hand-written files (fast)
#   just check-gen  → Verify generated files are up-to-date (idempotency)
#   just docs       → Generate all documentation
#   just test       → Run all tests
#   just typecheck  → Run pyright on generated stubs
#   just diff       → Show what changed since last scan
#   just clean      → Remove generated files
#
#   --- CI PARITY ---
#   just preflight  → Run pre-commit hooks (mirrors CI lint exactly)
#   just ci         → Full local CI: preflight + check-gen + test
#
#   --- 100x DX COMMANDS ---
#   just watch      → Auto-run generate+test on changes
#   just repl       → Pre-loaded IPython playground
#   just worktree N → Create isolated worktree + install deps
#   just add-cookbook "Name" → Scaffold new example
#
# First-time setup:
#   just setup
#
# Architecture note:
#   Generated files (agent.py, workflow.py, etc.) are owned by `just generate`.
#   Hand-written files (_base.py, _context.py, etc.) are owned by developers.
#   Formatters and pre-commit ONLY touch hand-written files.
#   `just generate` formats its own output as part of the generation pipeline.
#   See .gitattributes for the full generated file list.
