block-curl-pipe-sh

v0.0.5

Best-effort guard against piping a download into a shell or interpreter: curl, wget, lynx, aria2c, iwr/irm and similar fetchers piped into sh/bash/zsh/dash/ksh/fish/python/perl/ruby/node, bare, path-qualified or quoted, in a subshell group or behind sudo/exec/env/xargs/nohup/timeout; also bash -c "$(curl ...)", bash <(curl ...) and PowerShell `| iex`. Saving to a file, or piping into jq/tar/grep, is allowed. Bypasses: aliases, variables, obfuscation. Friction only.

block-destructive-commands

by chock-core

Best-effort guard against destructive commands, read as parsed commands (bash -c and cd chains included, echo excluded): rm -rf on absolute, home ($HOME/~) or root-adjacent paths (and PowerShell Remove-Item -Recurse); git push --force (not --force-with-lease), reset --hard, clean -f; kubectl delete; terraform destroy; aws s3 rm --recursive / rb --force; dropdb; helm uninstall/delete; docker volume rm/prune and system prune; gcloud ... delete; find -delete / -exec rm; shred; truncate; wipefs -a. git branch -D asks first. Verbs are matched position-aware, so a bucket or object NAMED like a verb is allowed, and a relative path in the working tree stays allowed. sudo, doas and pkexec are transparent. A pre-push hook refuses any non-fast-forward push -- force, +refspec or lease alike; a human escapes with git push --no-verify. Known bypasses: aliases, an unusual value-flag, interpreters and scripts. Friction, not a security boundary.

block-invisible-unicode

by chock-core

The mechanizable slice of prompt-injection defense, enforced at two points: at commit (the git hook, over staged changes) and at agent tool-use (over a tool call's arguments, as the agent writes) -- invisible and direction-override Unicode. Bidi controls make code read differently than it parses (Trojan Source, CVE-2021-42574); Unicode tag-block characters smuggle instructions that are invisible to a human reviewer but fully legible to the agent reading the file. Zero-width joiners and bidi marks (ZWJ/ZWNJ/LRM/RLM) are deliberately NOT matched -- they are legitimate in emoji sequences and in Persian, Arabic and Indic text -- so ordinary internationalised content passes; only the override/embed/isolate controls and the tag block, which have no honest use in a source tree, are blocked. Escape: 'pragma: allowlist invisible-unicode' on the same line.
