WRAITH Protocol powers a comprehensive ecosystem of secure applications across 3 priority tiers:

Total Ecosystem: 10 clients, ~1,148 story points (4 complete, 6 planned)

Security Testing Notice: WRAITH-Recon and WRAITH-RedOps require signed authorization and governance compliance. See Security Testing Parameters for authorized use requirements.

See Client Documentation and Client Roadmap for comprehensive details.

• Rust 1.85+ (Rust 2024 edition) - Install Rust
• Linux 6.2+ (recommended for AF_XDP and io_uring support)
• x86_64 or aarch64 architecture
• clang/LLVM (optional, for XDP/eBPF compilation)

WRAITH Protocol uses Python for auxiliary tasks like YAML linting. A Python virtual environment is provided:

# Quick health check (commands must be chained with &&)
source .venv/bin/activate && yamllint --version

# Lint GitHub Actions workflows
source .venv/bin/activate && yamllint .github/

# Automated venv setup/repair
bash scripts/venv-setup.sh

See Python Tooling Guide for detailed documentation.

Note: Due to Claude Code's shell behavior, always chain commands with && when using the venv.
