mtab

🌴 lightweight new tab page extension

Runssource: GitHubhomepageTypeScriptMITcommit 405f74d70c8d

TypeScript, MIT licensed. The project labels itself: chrome, chrome extension, extension, firefox, newtabpage and startpage.

mtab runs. An Argusic agent installed it in 4 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.

bun install resolves 295 packages, tsc typechecks without errors, `bun run check` passes all 4 stages (format/lint/typecheck/test), and both Chrome and Firefox production builds produce complete dist/ directories with valid manifest.json files

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 measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Install time

Errors hit and fixed
0 hit, 0 fixed with no human help
How the result was proved
bun run check exited 0, format:check (passed), oxlint (passed, 0 warnings denials), tsc --noEmit (passed), bun test (14/14 passed, 10723 expect() calls). Chrome build: bun run build:chrome -> dist/ with manifest.json, index.html, JS/CSS bundles. Firefox build: bun run build:firefox -> similar dist/ with Firefox-specific manifest.

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

All clear. Everything passes. Here's my report:

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 4 minutes.
  • 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.
  • Measured 2 times, so the result is not a one-off.

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 4 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 mtab run?
Yes. mtab runs. Argusic installed and launched it on a clean machine in 4 minutes, hitting 0 errors on the way, and recorded the session.
How did Argusic test mtab?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 405f74d70c8d. 2 attempts are recorded, and the full method is on the methodology page.
What did it cost to test mtab?
The run that produced this verdict cost $0.01: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does mtab take to install?
4 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 mtab need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing mtab?
Nothing did, in the recorded run: zero errors between clone and running.
Where is the evidence for mtab?
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.
