LOC Change Table

Use this skill when the user wants a repo-by-category table of line changes under a folder since a date.

How to run

The bundled script is the single source of truth. Run it and present its output verbatim. Do not hand-compute counts, and do not substitute ad-hoc git log/git diff one-liners — they count differently and produce inconsistent results.

  1. Resolve the inputs:

- Folder: use the user's path, or the current working directory if none is given. - Date: required. If the user did not give one, ask. Accept any git-compatible form, such as 2026-06-01, last Friday, or 2 weeks ago.

  1. Run:

``bash python3 scripts/locchangetable.py <folder> --since <date> ``

  1. Present the Markdown table the script prints, then relay its trailing notes (hidden repos, empty-tree warnings, skipped repos). Do not drop the notes — the empty-tree warning is how a wrong date is caught.

Flags

  • --include-uncommitted — also count working-tree changes (only when the user asks for uncommitted work).
  • --include-binary — count each changed binary file as 1 line.
  • --show-empty — also list repos with zero changes (hidden by default).

Behavior

  • Counts added + deleted per file from git diff --numstat, diffing HEAD against the last commit before --since.
  • If no commit predates the date, the repo is diffed against the empty tree (full history) and flagged in a note — surface that note so inflated totals are visible.
  • Each nested git repository is its own row; repos with no changes are hidden; rows are sorted by total descending.
  • Repos with no commits or git errors are reported under "Skipped".
