agent-purge
One persona, many coding agents. Replace or inject system prompts across codex, claude, opencode, grok, omp, hermes, pi, zcode - with a local web console.

agent-purge runs. An Argusic agent installed it in 5 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
agent-purge CLI is functional from source checkout: all 8 subcommands (help, status, ls, use, mode, matrix, detect, web) work correctly, web server serves UI on port 7788 returning HTTP 200, and 70 test assertions pass. Added missing neutral.md persona template so first-run persona auto-generation works.
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.

What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- Missing lib/templates/personas/ directory - neutral.md starter persona not auto-generated on first run3 minutes
- npm install -g requires root permissions (EACCES)1 minute
- Install time
- 5 minutes
- Cold machine to finish
- 4 minutes
- Errors hit and fixed
- 2 hit, 2 fixed with no human help
- How the result was proved
- npm test exited 0 (70 assertions passed); node bin/agent-purge.mjs web served HTTP 200; node bin/agent-purge.mjs --help printed usage; node bin/agent-purge.mjs codex --dry-run output correct launch command; node bin/agent-purge.mjs status printed 12 harnesses

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.
- Recovered from all 2 errors 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.
What did not, or is not known
- Took 5 minutes to install, slower than the median of the 19 comparable projects Argusic has measured.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
Of the 20 claude-code projects Argusic has installed and timed, agent-purge was the 12th fastest to reach a running state, and 19 of 20 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 5 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/agent-purge)Questions
- Does agent-purge run?
- Yes. agent-purge runs. Argusic installed and launched it on a clean machine in 5 minutes, hitting 2 errors on the way, and recorded the session.
- How did Argusic test agent-purge?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 629494c706b6. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test agent-purge?
- The run that produced this verdict cost $0.06: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does agent-purge take to install?
- 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 agent-purge need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing agent-purge?
- 2 things broke in the recorded run, and 2 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does agent-purge compare with the alternatives?
- Of the 20 claude-code projects Argusic has installed and timed, agent-purge was the 12th fastest to reach a running state, and 19 of 20 reached one at all.
- Where is the evidence for agent-purge?
- 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.
