Add Vetto (daemon-less 0ms sandbox for Claude Code) to Companion Apps

[shleder]

Project Description

• Name: Vetto
• License: Apache-2.0
• Summary: Daemon-less, 0ms sandbox for Claude Code, Codex, and Cursor — Linux Landlock LSM (ABI v1-v6) + macOS Seatbelt, transparent PATH shimming, zero-config network allowlists, git rollback guard, and MCP server isolation without Docker.

Why it's useful for Claude Code developers

Running Claude Code unattended or with --dangerously-skip-permissions introduces credential-leak risks (~/.ssh, ~/.aws, .env). Vetto provides a native, unprivileged kernel sandbox with 0.002s overhead without requiring Docker, root, or virtualization.

Disclosure: I am the author/maintainer of Vetto.

Inline comments:
In `@README.md`:
- Line 1113: Update the Vetto README entry’s capability description to scope
network allowlists to Linux, replacing the unqualified “zero-config network
allowlists” wording with “Linux network allowlists” or an equivalent
platform-specific qualifier; leave the other feature claims unchanged.
- Line 1113: Update the Vetto entry in the README table to replace “git rollback
guard” with the documented capability name “Git push protection,” or explicitly
describe its file-byte rescue rollback without implying Git worktree rollback.

Updated the description in commit 806bdf4 to explicitly scope network allowlists to Linux and use 'Git push protection' matching the documented capability name. Thank you for the review!

Gentle nudge on this one — happy to trim the entry or match your table format if anything looks off. Just say the word.
