spec-kitty runs. An Argusic agent installed it in 0.2 minutes and hit 1 error and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Spec Kitty CLI 3.2.7rc1 installed in venv at /work/repo/.venv, all major test suites pass with 1903+ tests passing and 0 failures, spec-kitty init creates a working project with Codex agent integration.
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.
- mypy not installed (test dependency gap)3.3 minutes
- Install time
- under a minute
- Cold machine to finish
- 82 minutes
- Errors hit and fixed
- 1 hit, 1 fixed with no human help
- How the result was proved
- spec-kitty --version returned 'spec-kitty-cli version 3.2.7rc1'; spec-kitty init . --ai codex created project with config.yaml and 105 tool surfaces; spec-kitty config displayed project config; pytest tests/unit/ passed 449/449; pytest tests/specify_cli/lanes/ passed 131/131; pytest tests/specify_cli/status/ passed 475/475; cumulative test count ~1903 passed, 0 failures

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

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 0.2 minutes, faster than the median of the 8 comparable projects Argusic has measured.
- Recovered from all 1 error 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 MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
Of the 9 agentic-coding projects Argusic has installed and timed, spec-kitty was the 2nd fastest to reach a running state, and 8 of 9 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 0.2 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/spec-kitty)Questions
- Does spec-kitty run?
- Yes. spec-kitty runs. Argusic installed and launched it on a clean machine in 0 minutes, hitting 1 error on the way, and recorded the session.
- How did Argusic test spec-kitty?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 614c52cb382d. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test spec-kitty?
- The run that produced this verdict cost $0.37: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does spec-kitty take to install?
- 0.2 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 spec-kitty need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing spec-kitty?
- 1 thing broke in the recorded run, and 1 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does spec-kitty compare with the alternatives?
- Of the 9 agentic-coding projects Argusic has installed and timed, spec-kitty was the 2nd fastest to reach a running state, and 8 of 9 reached one at all.
- Where is the evidence for spec-kitty?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
