cost-xray runs. An Argusic agent installed it in 0.5 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
All 223 tests pass, both mitmproxy modes (reverse and forward) bind correctly and route traffic, the TUI renders to the display with captures shown, and the full import chain from capture through materialization to pricing works without errors.
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.
- Install time
- under a minute
- Cold machine to finish
- 5 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- pytest: 223 passed, 2 skipped; mitmdump reverse proxy on :8788 returned HTTP 405 from api.anthropic.com (expected, no auth); mitmdump forward proxy on :8789 accepted CONNECT; TUI launched on :99 via textual; all 18 modules import clean

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

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, faster than the median of the 3 comparable projects Argusic has measured.
- Nothing broke on the way: zero errors between clone and running.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, 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.
Of the 4 claude-code projects Argusic has installed and timed, cost-xray was the 1st fastest to reach a running state, and 3 of 4 reached one at all.
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.
- Following its own README: the documented path worked with nothing to fix.
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/cost-xray)Questions
- Does cost-xray run?
- Yes. cost-xray runs. Argusic installed and launched it on a clean machine in 1 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test cost-xray?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 5d69deb210fc. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test cost-xray?
- The run that produced this verdict cost $0.03: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does cost-xray 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 cost-xray need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing cost-xray?
- Nothing did, in the recorded run: zero errors between clone and running.
- How does cost-xray compare with the alternatives?
- Of the 4 claude-code projects Argusic has installed and timed, cost-xray was the 1st fastest to reach a running state, and 3 of 4 reached one at all.
- Where is the evidence for cost-xray?
- 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.
