protect-test-integrity

v0.0.2

Blocks a commit that turns tests green by weakening them instead of fixing the code: a deleted test file, a net loss of assertions across the change, or a vacuous assertion (assert True, expect(true).toBe(true)) added in place of a real one. Covers Python, JS/TS, Go and Java test layouts. Mechanised slice of agent-discipline's never(fix_test_by) rule; added skips are block-test-skips. Enforced at commit and at agent tool-use (an edit that weakens a test is judged against the file on disk, the turn's end against HEAD; Edit and Write cannot delete a file). A reviewed exception carries 'chock: allow test-integrity' on an added line of the test file; a waiver is honoured at commit only, never in the agent. [Session-enforced via PreToolUse and Stop hooks; needs git and a Python 3.11+. PreToolUse judges the file a tool call would write; Stop re-reads what the turn actually left on disk, so a file written through a shell heredoc is judged too. With no working Python the hook exits 2; without git, fail-open clients allow silently. A gate that cannot reach a decision refuses rather than allowing one it never judged. Enforcement at every commit and in CI still needs chock installed in the repo. Codex requires a one-time trust review per hook -- the plugin is ADVISORY until you approve its hook, and a plugin update voids that trust until re-approved.]

trigger: edits without reading, unverified completion claims, weakened tests, dead code. avoid: skipping verification, deleting assertions, leaving unused code.

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.
