sync-depslisted

# Sync Dependencies Derives the project's dependency list from **actual imports in source files** — one scan, one canonical list, propagated to every dep file. No manual bookkeeping; no drift between `requirements.txt` and `pyproject.toml`. ## When to Use This Skill - User says "update requirements.txt", "sync deps", "fix requirements", "update deps" - User says "update pyproject.toml dependencies", "sync dependency files" - After adding or removing a package to the project - Before a release or a code review --- ## Single Source of Truth ``` source files (.py, .ipynb) │ ▼ sync_deps.py ← ONE scan, ONE canonical list │ ├──▶ requirements.txt ├──▶ pyproject.toml [project.dependencies] ├──▶ environment.yml (if present) └──▶ setup.cfg (if present) ``` Everything is derived; never edit dep files by hand. --- ## Step 1 — Run the scanner Run the bundled script from the **repo root** (not from inside the skill folder): ```bash python .claude/skills/sync-deps/scripts/sync_deps.py ``` The script outputs one `package>=X.Y` line per third-party dependency, sorted alphabetically, to **stdout**. Capture it: ```bash python .claude/skills/sync-deps/scripts/sync_deps.py > /tmp/deps_raw.txt ``` Inspect the output before writing anything. If a package is missing or wrong, update `IMPORT_TO_PACKAGE` in the script — that is the only place to change. --- ## Step 2 — Write `requirements.txt` Replace the full con
