Agent Sync
Coordinate concurrent coding agents with expiring claims, race-free ids and a durable run journal.
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 SECRETS_PATH_DOTENV OBFUSCATION_FILE_OVER_READ_CAP
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
bin/agent-sync.js, line 243
fs.rmSync(SHADOW, { recursive: true, force: true }); - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.

curl -sS --config - <<EOF - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.gitignore, line 14
# untracked-but-unignored .env at a sibling's repo root, one `git add -A` - OBFUSCATION_FILE_OVER_READ_CAP Note
A file was over the read cap and was not fully read.

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.
