# Fail if any markdown file breaks the shared naming convention.
#
# Three namespaces -- README.md, CLAUDE*.md, DOCS*.md. TODO*.md is banned:
# tasks live in the todo app (MCP add_task, or todo_note.dart --repo).
#
# This is the REAL gate. Per-repo scripts/check_md_naming.sh files are thin
# shims that exec this one -- do not overwrite this file with a shim, or every
# shim execs itself forever.
#
# The real check lives in Python (md_naming/check.py) so that the gate and any
# survey share one exemption list -- see rules/shell.instructions.md on never
# embedding another language's logic inline.
#
# Usage:
#   scripts/check_md_naming.sh <file> [<file> ...]   # pre-commit passes these
#   scripts/check_md_naming.sh --all                 # whole tree, from cwd
