Agent Link
Two coding agents, on two different machines, talking to each other directly.
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
link/client.py, line 256
def spawn_daemon() -> subprocess.Popen: - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
link/daemon.py, line 1546
# inbox fetch (and so the hook), or the human never hears the answer.
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
