trw_mcp-0.34.1/CHANGELOG.md:107
- **`tools/build` missing from wheel** — `.gitignore` had unanchored `build/` which excluded `src/trw_mcp/tools/build/` from the published package. Anchored to `/build/` so only the root build directory is ignored.
- **`install.sh` served from platform** — added to `platform/public/` so `curl -fsSL https://trwframework.com/install.sh | bash` works via Amplify without a separate CDN setup.
- **trw-shared removed from build chain** — `Makefile`, `build_installer.py`, and installer template no longWhy was this flagged?
A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.

- **Installer device auth integration** — `_prompt_api_key()` in `install-trw.template.py` now tries device auth first, falls back to manual key paste. Accepts `trw_dk_` key prefix. New `--skip-auth` flag to skip platform connection entirely.
- **Bootstrap script** (`scripts/install.sh`) — lightweight bash script for `curl -fsSL https://trwframework.com/install.sh | bash`. Checks Python 3.10+, `pip install trw-mcp` with fallbacks, `init-project`, optional device auth. Supports `--api-key`, `--skWhy was this flagged?
