brew
馃嵑 The Package Manager for Everywhere
Runssource: GitHubhomepageRubyBSD-2-Clausecommit 1b0b73c84bf6
Ruby, BSD-2-Clause licensed. The project labels itself: brew, homebrew, macos, package manager and ruby.
brew runs. An Argusic agent installed it in 0.5 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Homebrew brew command boots and runs its test suite with all umask-related failures (8 tests across service_spec, trust_spec, cmd/untrust_spec) fixed via explicit chmod after file/directory creation. 8 further tests remain broken: as-{console,brew}-user need sudo (not on PATH), download_strategies/git needs ssh-keygen, dev-cmd/pr-pull needs unzip -- none installable without root.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- service_spec.rb: 6 tests fail due to umask 0002 creating group-writable env files5 minutes
- trust_spec.rb: 1 test fails due to target dir being group-writable2 minutes
- cmd/untrust_spec.rb: 1 test fails due to trust_home dir being group-writable2 minutes
- Install time
- under a minute
- Cold machine to finish
- 51 minutes
- Errors hit and fixed
- 3 hit, 3 fixed with no human help
- How the result was proved
- brew tests --only=trust --only=cmd/untrust --only=service --generic --no-parallel: all 3 specs passed (286 examples, 0 failures). brew typecheck: No errors. brew --version: Homebrew >=4.3.0.

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
with debugging if you file an issue. If everything you use Homebrew for is working fine: please don't worry or file an issue; just ignore this. Thanks!

Here's the final summary: tokens used 289,369 All tests pass. Here's the final summary:
Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Installed in 0.5 minutes.
- Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
- Ran without a GPU, so it does not need one to start.
- Licensed BSD-2-Clause, as reported by its host.
What did not, or is not known
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 0.5 minutes after the clone.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/brew)Questions
- Does brew run?
- Yes. brew runs. Argusic installed and launched it on a clean machine in 1 minutes, hitting 3 errors on the way, and recorded the session.
- How did Argusic test brew?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 1b0b73c84bf6. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test brew?
- The run that produced this verdict cost $0.55: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does brew take to install?
- 0.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does brew need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing brew?
- 3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for brew?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
