FrontierAgent
🧩 FrontierAgent, our agent framework, open-sourced alongside it, native command-line TUI, ReAct and Agent Team modes, one command on macOS and Linux, no preinstall, no hard Docker dependency.
Runs with mockssource: GitHubhomepagePythonApache-2.0commit a3c1be339c24
Python, Apache-2.0 licensed. The project labels itself: agent orchestration, agentic ai, agentic framework, ai agents, harness, multi agent, terminal agent and tui.
FrontierAgent runs, with stand-ins for the services it depends on. An Argusic agent installed it in 0.1 minutes and hit 4 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
FrontierAgent 0.1.0 installs cleanly with `uv sync --frozen --extra sandbox --extra document-readers --extra eval --extra dev`. The CLI binary prints version and full help output. The test suite passes with 1614 passing tests across 6 test groups covering the core agent engine (ReAct/Agent Team workflows, streaming, tool calls, compaction, sandboxing, session/run management, error recovery, provider configuration).
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.
- CLI --print mode failed to reach a standalone mock server due to asyncio httpx IPv6 resolution order and background process lifecycle in this shell; the project's own in-process MockLLMServer (used in test_hf_space_runtime.py) works correctly.10 minutes
- uv not in PATH at start0 minutes
- TUI tests (apodex/tests/test_tui.py, 170 tests) need a real Textual terminal
- test_a_slow_endpoint_fails has an intentional 90s mock-server delay, hangs outside its 120s timeout on single run
- Install time
- under a minute
- Cold machine to finish
- 40 minutes
- Errors hit and fixed
- 4 hit, 4 fixed with no human help

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.
=== Verification === The test suite exercises the real React and Agent Team workflows via MockLLMServer (a threaded HTTP mock Argusic endpoint) in test_hf_space_runtime.py. No API key, GPU, or network egress required per test architecture. Now I have all the data needed for the final report. Let me clean up: exec /bin/sh -lc 'pkill -f "mockd.py" 2>/dev/null; echo "done"' in /work/repo exited 143 in 0ms: I have all the information needed. Here is the comprehensive report of what I did and found. tokens used 186,340 I have all the information needed. Here is the comprehensive report of what I did and found.
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 0.1 minutes, faster than the median of the 4 comparable projects Argusic has measured.
- Recovered from all 4 errors without a human stepping in, which says the failures are documented well enough to solve.
- Licensed Apache-2.0, 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.
Of the 5 agent-orchestration projects Argusic has installed and timed, FrontierAgent was the 1st fastest to reach a running state, and 4 of 5 reached one at all.
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/frontieragent)Questions
- Does FrontierAgent run?
- FrontierAgent runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 0 minutes, hitting 4 errors on the way, and recorded the session.
- How did Argusic test FrontierAgent?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit a3c1be339c24. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test FrontierAgent?
- The run that produced this verdict cost $0.18: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does FrontierAgent take to install?
- 0.1 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 FrontierAgent need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing FrontierAgent?
- 4 things broke in the recorded run, and 4 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does FrontierAgent compare with the alternatives?
- Of the 5 agent-orchestration projects Argusic has installed and timed, FrontierAgent was the 1st fastest to reach a running state, and 4 of 5 reached one at all.
- Where is the evidence for FrontierAgent?
- 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.
