# Improve @ file search: include specific hidden dirs
This should close#2980
## What
- Extend `@` fuzzy file search to include select top-level hidden
directories:
`.github`, `.gitlab`, `.circleci`, `.devcontainer`, `.azuredevops`,
`.vscode`, `.cursor`.
- Keep all other hidden directories excluded to avoid noise and heavy
traversals.
## Why
- Common project config lives under these dot-dirs (CI, editor,
devcontainer); users expect `@.github/...` and similar paths to resolve.
- Prior behavior hid all dot-dirs, making these files undiscoverable.
## How
- In `codex-file-search` walker:
- Enable hidden entries via `WalkBuilder.hidden(false)`.
- Add `filter_entry` to only allow those specific root dot-directories;
other hidden paths remain filtered out.
- Preserve `.gitignore` semantics and existing exclude handling.
## Local checks
- Ran formatting: `just fmt`
- Ran lint (scoped): `just fix -p codex-file-search`
- Ran tests:
- `cargo test -p codex-file-search`
- `cargo test -p codex-tui`
## Readiness
- Branch is up-to-date locally; tests pass; lint/format applied.
- No merge conflicts expected.
- Marking Ready for review.
