What it is
A DSH plugin that intercepts bash/pwsh tool calls before they run, judging whether a command will irreversibly delete or overwrite real data. Built for DSH users who want a hard interception rather than a model nudge.
How it uses Jev
After offline L0 static rules and a read-only pre-screen, Jev answers one yes/no question: will this command irreversibly delete or overwrite the user's real data? Two thresholds split the probability into allow, revise, or block; escalate handles hard-rule 'always ask' cases and spent retry budgets.
Primitives:choice
Technique worth stealing
Anchor dangerous-command rules at command position only, so mentions in arguments are not false positives and buried commands are not missed.
Try it
dsh plugin --profile web add github:7starsseeker/dsh-jev-guard, then node bin/guard.mjs selftest
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
