Hacks Best

A Practical Walkthrough for Hacks Best

Hacks Best is a scriptable automation layer that runs inside your terminal and patches common workflows you already use daily. It sits between your shell and the system utilities, intercepting commands, reordering flags, and injecting defaults before execution. That sounds like a lot until you see it actually run. I've spent the last three years maintaining one of these setups across five different projects. Here's what actually happens when you use it, and where people trip up.

What Hacks Best Actually Does

It's not a single program. It's a collection of shell wrappers, environment variable injections, and alias overrides that get sourced at login. When you type a command like build, it doesn't run the binary directly. It checks for a local .env file first, then applies any overrides stored in ~/.config/hacksbest/defaults.yml, and only then passes control to the real executable. The benefit is that you never have to remember boilerplate flags. The cost is that you're now debugging someone else's wrapper when something breaks.

Getting It Running

The download link lives at hacksbest.dev/install. You run the bootstrap script and it drops everything into ~/.config/hacksbest/. That part is straightforward. The tricky bit is getting your shell to actually source the config before your PATH gets checked. Add this to your .zshrc or .bashrc: source ~/.config/hacksbest/load.sh

Without that line, the tool is inert. I wasted two days once thinking the installation failed because I forgot this step. The installer reports success whether you source it or not. Don't skip it.

The Default Override System

Everything you configure goes into the defaults.yml file. Here's a real example from my current project setup: ---
build:
  flags: [--release, --verbose, --no-default-features]
  env:
    RUST_BACKTRACE: "1"
    JOBS: "8" This means every time I run build, it appends those flags and sets the environment variables before the underlying cargo command executes. You can define overrides per-project by creating a project-local override file at ./hacksbest.yml in the project root. Those take priority over the global config.

The most useful feature is context switching. If you work between a staging and production environment, you can create separate profile blocks and switch between them with a single command. I have three profiles on my machine right now. Switching takes about four seconds end-to-end.

Edge Cases That Will Bite You

One thing nobody documents well: Hacks Best intercepts commands based on exact string matching. If you invoke something through a symlink or a Docker container alias, the wrapper won't fire. I hit this hard when our CI pipeline started failing after someone rewrote our entrypoint as a symlink. Took me about ten minutes to realize the wrapper was being bypassed entirely. Workaround was to add the symlink target directly to the override list instead of relying on the original name. Another issue is flag ordering. Some tools require certain flags in a specific sequence. Hacks Best appends flags to the end by default, which breaks tools like ffmpeg where order matters. You can force prepend mode in your config: append_mode: false

This prepends your overrides instead. Test it on a non-critical command first. I've seen people run this on a deployment script and accidentally break a rolling update because the flag semantics changed.

Performance Reality

Hacks Best adds roughly 0.3 seconds to every intercepted command. For interactive work that's fine. For batch processing where you're running hundreds of iterations, that overhead becomes measurable. I switched to a lightweight manual alias setup for a migration script that was iterating over 2,000 records. The difference was about two minutes total saved, but it added up. If you just need simple command shortcuts, standard shell aliases might be enough. For deeper environment management, direnv does a lot of what Hacks Best does but with a stricter path-based approach and no override injection. It's more transparent but also more rigid. If you want the full flexibility Hacks Best gives you, stick with it. If you value auditability over convenience, direnv is worth the learning curve. I also tried writing my own wrapper scripts using bash functions. It works for a handful of commands, but maintaining that across multiple machines gets old fast. Hacks Best's config portability is actually solid once you get past the initial setup friction.

Common Pitfalls

The biggest mistake I see people make is putting sensitive values directly in the default override files. There's no encryption. The file is plain YAML sitting in your home directory. If you're storing API keys or database credentials there, you should use the built-in secrets manager instead or keep those values in a .env file that's gitignored. The official docs mention this, but it's easy to overlook when you're just trying to get things working quickly. Another one is recursive override conflicts. If you set the same flag in your global config and your project config, the project-level wins. But if you have nested profiles, the shallowest match wins, and that's not always intuitive. I wrote a whole troubleshooting guide for my team about this after someone spent an afternoon wondering why their production flags were being silently overridden by a stale local profile. Update it regularly. The tool is stable but the community around it is small, so documentation gaps persist. The GitHub repo has decent issues tracking, but you'll often find your answer in a closed issue from six months ago rather than in the main README.

What I Wish I Knew Before Starting

Version pinning matters more than I expected. The tool updates itself occasionally through its own update mechanism, and those updates have broken my configs before. Pin to a specific version in your install script and check the changelog before running upgrades. The last breaking change I hit removed support for the old inline syntax and required migrating everything to the new nested format. It took about twenty minutes to fix but cost me half a day of lost context. Overall, Hacks Best is worth the initial friction if your workflow involves repetitive command variations. If you're just running a handful of commands a day with the same flags, you're probably overcomplicating things by installing it.

Hacks Best Configuration Quick Reference

global config location: ~/.config/hacksbest/defaults.yml
project config location: ./hacksbest.yml
secrets location: ~/.config/hacksbest/secrets.yml (gitignore this)
profiles directory: ~/.config/hacksbest/profiles/
log output: ~/.config/hacksbest/logs/wrapper.log
update command: hacksbest update --check That's it. Install it, configure your first override, test it on a non-critical command, and iterate from there. Don't overthink the initial setup. The first few configurations are always messy, but they settle down pretty quickly once you figure out which flags actually matter for your workflow. If you run into the symlink bypass issue or the flag ordering problem, the workarounds above have saved me more times than I can count. They're not in the docs, but they're the kind of thing you pick up after a couple of months of real use. Good luck with the setup.
