ralph-claude-code

Autonomous AI development loop for Claude Code with intelligent exit detection

Runssource: GitHubShellMITcommit e8533cc3f009

Shell, MIT licensed. The project labels itself: ai, ai agent, ai agents, ai development, ai development tools, claude code, claude code cli and development tools.

ralph-claude-code runs. An Argusic agent installed it in 0.5 minutes and hit 2 errors on a clean machine with no GPU, and the whole session was recorded.

Ralph is installed globally with 7 CLI commands, all 1319 tests pass, project setup works, and dry-run mode simulates loops without API calls.

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 90 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.

Time lost to each failure while testing ralph-claude-code, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

  • ralph-setup requires git user.name/user.email to be configured (non-interactive git commit fails without them)1 minute
  • ralph-setup --help treats --help as a project name instead of showing help

How the result was proved
npm test via 'bats tests/unit/ tests/integration/' and 'bats tests/e2e/', 1000 unit + 279 integration + 18 e2e + 13 + 9 standalone = 1319 tests, all passing. ralph --help shows full docs. ralph --dry-run --calls 2 simulates 2 loops successfully.

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.

**Tests**: Ran the full test suite with `bats` from `node_modules/.bin/bats`:
- **Unit tests**: 1000/1000 passed
- **Integration tests**: 279/279 passed
- **E2E tests**: 18/18 passed
- **Standalone scripts**: `tests/test_error_detection.sh` — 13/13 passed; `tests/test_stuck_loop_de…
**Verification**:
- `ralph --help` shows full documentation
- `ralph --status` reports "No status file found" (expected — never ran a real loop)
- `ralph-stats` returns JSON error about no metrics (expected)
**Issue**: `ralph-setup --help` misbehaves (treats `--help` as project name). This is a pre-existin…
**Project setup** (after configuring git user name/email): `ralph-setup testproject` successfully c…
**Dry-run**: `ralph --dry-run --calls 2` within the test project correctly simulates loops 1 and 2,…

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 0.5 minutes, faster than the median of the 52 comparable projects Argusic has measured.
  • 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

  • Hit 2 errors during setup, 1 of which were not solved.
  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Of the 53 ai projects Argusic has installed and timed, ralph-claude-code was the 6th fastest to reach a running state, and 40 of 53 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.

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 ralph-claude-code run?
Yes. ralph-claude-code runs. Argusic installed and launched it on a clean machine in 1 minutes, hitting 2 errors on the way, and recorded the session.
How did Argusic test ralph-claude-code?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit e8533cc3f009. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test ralph-claude-code?
The run that produced this verdict cost $0.04: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does ralph-claude-code 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 ralph-claude-code need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing ralph-claude-code?
2 things 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 ralph-claude-code compare with the alternatives?
Of the 53 ai projects Argusic has installed and timed, ralph-claude-code was the 6th fastest to reach a running state, and 40 of 53 reached one at all.
Where is the evidence for ralph-claude-code?
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.
