🔭 Scope Creep Detector
Checks a working, staged, saved, or branch diff against a one-line intent. It flags unrelated paths, new dependencies, public API renames, config or CI edits, oversized hunks, formatting-only files, and subsystem spread. The output is a local JSON report for keep, split, or justify decisions.
The demo analyzes a "fix null deref in parser" change that also touched CI config, added a dependency, and dropped in an unrelated file. The parser fix is kept; the rest is flagged.

Run
Ask the agent:
Did my change grow beyond the parser fix I intended?
Or run the deterministic core directly:
python3 scripts/scope_creep.py --repo /path/to/repo \
--intent "fix null dereference in parser" --json
Use --staged for the index, --base main for a branch diff, or --diff -
for unified diff input on stdin. The script uses only the Python standard
library, makes no network calls, and does not modify the repository.
