zero

The coding agent that answers to you, your model, your machine, your rules.

Runssource: GitHubhomepageGoMITcommit 99721c762f37

Go, MIT licensed. The project labels itself: ai, ai agent, anthropic, cli, code assistant, coding agent, developer tools and gemini.

zero runs. An Argusic agent installed it in 2 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.

Zero v0.9.0 builds from source, passes all 87 test packages, passes go vet, format check, vulncheck, smoke test, and answers all CLI commands (help, models list, providers list, doctor) on linux/amd64.

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).

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.

**Build verification** (`go run ./cmd/zero-release build`): produced `./zero` (version 0.9.0, linux…
**Smoke test** (`go run ./cmd/zero-release smoke`): `zero smoke check passed (0.9.0)`.
**Tests**: `go test ./...` — 87 test packages all passed (0 failures).
**Formatting** (`make fmt-check`): clean.
**Vet** (`go vet ./...`): clean.
**Vulnerability check** (`make vulncheck`): No vulnerabilities found.
**Diff hygiene** (`git diff HEAD --check`): clean.
**Functional commands exercised**:
- `./zero --help` — listed all 30+ available commands.
- `./zero models list` — returned all known models (gpt-4.1, claude-sonnet-4.5, gemini-2.5-pro, etc…
- `./zero providers list` — returned `(none)` (expected — no API keys configured).
- `./zero doctor` — ran and reported on config, sandbox, LSP status (all expected warnings for a fr…

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 2 minutes, faster than the median of the 96 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 97 ai projects Argusic has installed and timed, zero was the 16th fastest to reach a running state, and 67 of 97 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 2 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.

Questions

Does zero run?
Yes. zero runs. Argusic installed and launched it on a clean machine in 2 minutes, hitting 0 errors on the way, and recorded the session.
How did Argusic test zero?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 99721c762f37. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test zero?
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 zero take to install?
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 zero need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing zero?
Nothing did, in the recorded run: zero errors between clone and running.
How does zero compare with the alternatives?
Of the 97 ai projects Argusic has installed and timed, zero was the 16th fastest to reach a running state, and 67 of 97 reached one at all.
Where is the evidence for zero?
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.
