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.
