"""Tests that search_files excludes hidden directories by default.
|
|
|
|
Regression for #1558: the agent read a 3.5MB skills hub catalog cache
|
|
file (.hub/index-cache/clawhub_catalog_v1.json) that contained adversarial
|
|
text from a community skill description. The model followed the injected
|
|
instructions.
|
|
|
|
Root cause: `find` and `grep` don't skip hidden directories like ripgrep
|
|
does by default. This made search_files behavior inconsistent depending
|
|
on which backend was available.
|
|
|
|
Fix: _search_files (find) and _search_with_grep both now exclude hidden
|
|
directories, matching ripgrep's default behavior.
