agent-beacon
The cross-harness, self-improving memory layer for AI agents.
Runs with mockssource: GitHubhomepageGoMITcommit 7e47847cf18f
Go, MIT licensed. The project labels itself: agent ai cli, agent harnesses, agent security, browser extension, ci, claude code, cloud and codex.
agent-beacon runs, with stand-ins for the services it depends on. An Argusic agent installed it in 8 minutes and hit 3 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
Go 1.24.13 (auto-proxied to Go 1.25.0), Node 22.14.0, and Bun 1.4.2 are installed as user tools. All Go modules build and all test suites pass. All plugin and SDK npm/bun tests pass. Browser extension tsc check and 177 unit tests pass. The beacon-sandbox end-to-end scenario remains ungated because it requires real Modal and Anthropic credentials which cannot be mocked.
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 92 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.
- Go 1.24+ not installed on system1 minute
- Node.js v18 too old for browser-extension (needs >=22)1 minute
- bun not installed and installer requires unzip (not available)1 minute
- Install time
- 8 minutes
- Cold machine to finish
- 9 minutes
- Errors hit and fixed
- 3 hit, 3 fixed with no human help
- How the result was proved
- All 6 Go test suites passed (cli/beacon, cli/beacon-hooks, collector-builder/exporter/beaconjsonexporter, pkg/asymptoteobserve, beacon-sandbox, plus cli/beacon internal/endpoint -race), SDK npm test 22 passed, browser-extension npm test:unit 177 passed, all 7 bun plugin test suites passed (92 total tests)
- Model tokens used

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
- Behaviour against real services
- this run was verified against stand-in services only
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
- `plugins/pi-beacon`: 12 passed - `plugins/omp-beacon`: 23 passed - `plugins/openclaw-beacon`: 17 passed - `plugins/prime-beacon`: 15 passed - `plugins/omo-beacon`: 16 passed 7. **Packaging scripts** — `test-endpoint-scripts.sh` passed (Safari packaging checks ok); `smoke-e… 8. **Beacon sandbox** — `go run ./cmd/beacon-sandbox doctor` reports 2 unfixable items: `modal_auth… **Errors encountered and fixed:** - Go not installed → downloaded binary (no root) - bun installer needed `unzip` → downloaded zip + extracted via Python3 - Node 18 too old → downloaded Node 22 binary - No root → all tools installed as user binaries
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
- Installed in 8 minutes.
- Recovered from all 3 errors without a human stepping in, which says the failures are documented well enough to solve.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
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-beacon)Questions
- Does agent-beacon run?
- agent-beacon runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 8 minutes, hitting 3 errors on the way, and recorded the session.
- How did Argusic test agent-beacon?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 7e47847cf18f. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test agent-beacon?
- The run that produced this verdict cost $0.09: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does agent-beacon take to install?
- 8 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-beacon need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing agent-beacon?
- 3 things broke in the recorded run, and 3 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for agent-beacon?
- 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.
