allgood
✅ Quickly set up a health check page for your Rails app
Runs with mockssource: GitHubRubyMITcommit b71d1cb5d299
Ruby, MIT licensed. The project labels itself: downtime, health check, healthcheck, kamal, performance, performance testing, rails and ruby.
allgood runs, with stand-ins for the services it depends on. An Argusic agent installed it in 25 minutes and hit 5 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Allgood gem v0.3.0 installs, builds, and all 403 tests pass in Ruby 3.3.12 / Rails 8.1 on x86_64 Linux container 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 92 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.

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.
- How the result was proved
- runs before 2026-09-07 did not record the command used to check the result
- 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
- Behaviour against real services
- this run was verified against stand-in services only

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
- Installed in 25 minutes.
- Recovered from all 5 errors without a human stepping in, which says the failures are documented well enough to solve.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
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/allgood)Questions
- Does allgood run?
- allgood runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 25 minutes, hitting 5 errors on the way, and recorded the session.
- How did Argusic test allgood?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit b71d1cb5d299. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test allgood?
- The run that produced this verdict cost $0.18: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does allgood take to install?
- 25 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 allgood need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing allgood?
- 5 things broke in the recorded run, and 5 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for allgood?
- 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.
