Use when building, backtesting, or deploying algorithmic trading systems with NautilusTrader (nautilus_trader) — writing Strategy/Actor classes and StrategyConfig, configuring BacktestNode/BacktestEngine, constructing instruments, order management, ParquetDataCatalog/wranglers, message bus and custom data streams, indicators, portfolio/analysis/report generation, or live TradingNode deployment. Curated for v1.230.0.
Inspect and extend Hermes Agent TUI capabilities, launch flags, hotkeys, composer input, and terminal behavior.
Use when modifying a multi-host Nix flake or dotfiles repo, especially host-specific inputs, overlays, lockfile scope, and evaluation checks.
GitHub auth setup: HTTPS tokens, SSH keys, gh CLI login.
Class-level Linux debugging workflow for authentication/PAM lockouts, desktop hardware/device stacks, and RAM/swap/CPU/process resource pressure.

This skill package was consolidated into linux-system-debugging during the umbrella-building pass. The class-level instructions now live under the authentication/PAM/faillock section of that umbrella skill.
Preserved package references:
references/screen-locker-shared-faillock-case.mdreferences/i3-lockscreen-replacement-faillock.mdUse when a Linux user reports known-password rejection, lockout earlier than expected, or differing auth behavior across sudo, TTY login, SSH, display manager, or screen unlock. Gather non-sudo evidence (id, whoami, loginctl, account state, faillock --user) before changing PAM. Correlate journal lines for faillock, PAM services, i3lock, display managers, TTY logins, and SSH. Avoid blind sudo probes because failed sudo can consume another shared pam_faillock failure.
Core durable lesson: pam_faillock tracks failures by user across participating PAM services, so a later prompt can appear to lock early because another service already added failures.
