Summary

The installers pinned resq-software/crates at d84cd961, which predates crates#206. A user who installs hooks without resq on PATH (the default path on a fresh machine) still gets the old blanket guard, [ -n "$GIT_HOOKS_SKIP" ] && exit 0. So GIT_HOOKS_SKIP=audit looks selective but disables every check, the secret scan included. The bats suite tested crates master rather than the pin, which is why CI passed for behaviour the installer never shipped.

This PR changes:

  • Repin install-hooks.sh, install-hooks.ps1 and the install-resq.sh cargo fallback to 72e0ae49 (resq-cli-v0.5.2, on crates master), with new hook digests. The digests were checked against both the git objects and the raw endpoint.

  • Tests run against what ships. tests/hooks/helpers.bash now reads the pin from install-hooks.sh.

    • Only the pinned SHA is cached across runs, and every cached file is checked against the installer's digests, so a stale, half-written or tampered cache is refetched.
    • Moving refs such as master, and custom raw bases, are fetched fresh per run.
    • RESQ_HOOK_SRC_DIR (local template dir) is used as-is.
    • A new schedule/dispatch-only bats-upstream job keeps testing crates master, so drift shows up before the next pin bump.
  • tests/hooks/git-hooks-skip.bats (35 cases) covers:

    • every token and separator;
    • the fail-closed and inert-token cases;
    • the exact flags passed to resq.

    The fake resq stub now matches plain-mode run_plain, which has no versioning step, and records its argv. 30 of the 35 cases fail against the old pin.

  • Docs and help text:

    • The granular token list is documented.
    • The installer message said hooks "soft-skip" without resq. At this pin pre-commit fails closed and refuses the commit, so that message would have told every first-time user the opposite of what happens. It's corrected in install-hooks.sh, install-hooks.ps1 and AGENTS.md.
    • The docs note that prepare-commit-msg does not parse GIT_HOOKS_SKIP at this pin.
  • VERSION 0.4.6, re-stamped with bin/stamp.sh.

Merging this is a release: the VERSION change makes release.yml tag v0.4.6 and open the pin-bump PR. get.resq.software changes only when that PR merges.

Behaviour changes for users

  • Without resq on PATH, git commit is refused instead of soft-skipping. The deliberate opt-outs are GIT_HOOKS_SKIP=all and git commit --no-verify.
  • GIT_HOOKS_SKIP=audit (and every other token) now skips only that check, and says so in a banner.

Test plan

  • sh tests/run_all.sh: installers 5/5, lib 12/12, hooks 68/68, worker 81/81, stamp in sync
  • RESQ_HOOK_REF=master bats tests/hooks/: 68/68
  • Mutation check: git-hooks-skip.bats against d84cd961, 30/35 fail as intended
  • Tampered cache file is refetched and re-verified; a local RESQ_HOOK_SRC_DIR is left untouched
  • shellcheck (repo-wide, install.sh as POSIX sh); both .ps1 files parse under pwsh 7.6; zizmor and actionlint clean on hooks-tests.yml
  • CI required (pin/digest checks against the live endpoint)
  • windows-smoke on the PowerShell installers
  • After merge: confirm the auto-opened pin-bump PR and worker-live agree

Follow-ups (not in this PR)

  • install-resq.sh hardening:
    • fail on API errors instead of falling back to a cargo build;
    • choose the version properly over per_page=100;
    • add gh attestation verify;
    • write an install receipt.
  • crates: prepare-commit-msg should adopt the shared GIT_HOOKS_SKIP parser. Plain-mode resq pre-commit never runs versioning.
  • Consumer repos still carry the blanket guard in 5 of 6 hooks. That needs propagation PRs from crates.

Summary by CodeRabbit

  • New Features
    • Hook checks can be skipped selectively with named values in GIT_HOOKS_SKIP. Values are case-insensitive and can be separated by commas, colons, or spaces.
  • Bug Fixes
    • Pre-commit now refuses to proceed when resq is unavailable. Unrecognized skip values also fail closed, and secret scans cannot be skipped individually.
    • Hook installation now uses compatible embedded hooks or falls back to verified templates.
  • Documentation
    • Updated the bypass guidance, including --no-verify, all-off values, and exceptions for prepare-commit-msg.
  • Release
    • Updated the release version to 0.4.6.

…_HOOKS_SKIP

The installers pinned resq-software/crates at d84cd961, which predates
crates#206. Users installing without resq on PATH therefore still got the
blanket guard `[ -n "$GIT_HOOKS_SKIP" ] && exit 0`, so a selective-looking
GIT_HOOKS_SKIP=audit disabled every check, the secret scan included. The bats
suite fetched crates master instead of the pin, so CI passed for behaviour the
installer never shipped.

- Repin install-hooks.sh, install-hooks.ps1 and the install-resq.sh cargo
  fallback to 72e0ae49 (resq-cli-v0.5.2) with the new hook digests.
- Test the pinned commit by default. Only the pinned SHA is cached across runs,
  and each cached file is checked against the installer's digests; moving refs
  are fetched fresh per run. A weekly bats-upstream job keeps testing master.
- Add tests/hooks/git-hooks-skip.bats covering every token, separator, the
  fail-closed and inert-token cases, and the flags passed to resq. 30 of its 35
  cases fail against the old pin.
- Document the token list. Correct the installer message that said hooks
  soft-skip without resq: pre-commit now refuses the commit. Note that
  prepare-commit-msg does not parse GIT_HOOKS_SKIP at this pin.
- VERSION 0.4.6, re-stamped.

The changes update hook release pins to version 0.4.6, document GIT_HOOKS_SKIP token rules, add regression tests, and configure scheduled or manual hook tests against master.

Changes

Hook Skip Rules and Release Updates

Layer / File(s) Summary
Update hook release and template selection
VERSION, install.ps1, install.sh, scripts/install-hooks.ps1, scripts/install-hooks.sh, scripts/install-resq.sh
The release version changes to 0.4.6. The installers update hook digests and revision pins. They select embedded hooks only when the reported resq version is parseable and at least 0.4.3. The prepare-commit-msg digest remains unchanged.
Document skip-token and fail-closed rules
AGENTS.md, README.md, scripts/install-hooks.ps1, scripts/install-hooks.sh
The guides and installer messages describe named skip tokens, separators, case handling, fail-closed behavior, and bypass rules. They also describe pre-commit behavior when resq is unavailable.
Test hook selection and skip behavior
tests/hooks/helpers.bash, tests/hooks/git-hooks-skip.bats, tests/hooks/install-hooks.bats, tests/hooks/post-checkout.bats, tests/hooks/pre-commit.bats, .github/workflows/hooks-tests.yml
The test helpers select and validate hook sources and provide a fake resq backend. Bats tests cover skip-token behavior and embedded-template version selection. The workflow adds scheduled and manual runs against master.

This pull request introduces significant security and reliability enhancements to the developer onboarding and Git hooks process. After a thorough review, I have found no new vulnerabilities, bugs, or performance issues. Instead, the changes effectively address and mitigate several potential risks.

Here is a summary of the improvements:

  • Supply Chain Security: All scripts and Git hooks fetched from external sources (like the resq-software/crates repository) are now pinned to specific commit SHAs and their integrity is verified using SHA-256 checksums. This is a major improvement over the previous method of pulling from a mutable master branch and prevents the execution of untrusted code.

  • Safer Hook Bypassing: The GIT_HOOKS_SKIP mechanism has been completely redesigned to be more secure and intuitive. It now requires specific tokens to skip checks, fails closed on unrecognized input, and provides clear feedback to the user about which checks are running. Critically, it prevents the accidental disabling of the secret scan.

  • Increased Robustness: The installer scripts are more robust, with better error handling, improved signal trapping, and atomic file operations to prevent corrupted hook installations. Several platform-specific bugs, especially for PowerShell 5.1, have also been fixed.

  • Comprehensive Testing: A new, thorough test suite has been added to verify the behavior of the GIT_HOOKS_SKIP functionality, ensuring these security improvements are maintained.

Overall, this is an excellent pull request that significantly hardens the security posture of the project. The changes are well-executed and demonstrate a strong commitment to security best practices.

I approve of these changes.

the hook’s other behavior.

Review comments at @scripts/install-hooks.sh:
- Around line 80-89: Gate both hook installers’ preferred resq path on version
v0.4.3 or newer, and route older or unversioned binaries through the existing
verified-template fallback; leave the hook digests and CRATES_COMMIT unchanged.

Review comments at @tests/hooks/helpers.bash:
- Around line 69-75: Update the RESQ_HOOK_SRC_DIR validation in the hook source
setup so any supplied directory missing one or more required hooks is rejected
before creating the cache or fetching files. Allow the curl loop to run only
when no local source directory was supplied, and never write fetched hooks into
RESQ_HOOK_SRC_DIR.

install-hooks.{sh,ps1} took path 1 for any resq on PATH, and path 1 writes the templates embedded in the binary. A resq older than 0.4.3 therefore installed hooks with the blanket GIT_HOOKS_SKIP guard. Below the floor, or when the version cannot be read, the installers now use the pinned, digest-verified templates and say why. 0.4.3 through 0.5.2 embed templates byte-identical to the pin. Covered by tests/hooks/install-hooks.bats; 3 of its 5 cases fail without the floor.

Also: tests never fetch into a user-supplied RESQ_HOOK_SRC_DIR, and the prepare-commit-msg docs now state which commit sources it skips. Addresses review on #97.

Under ErrorActionPreference=Stop, a resq that cannot start (wrong architecture, corrupt file) threw from the --version probe and aborted the installer. It is now treated as an unreadable version, so the verified fallback runs. Addresses review on #97.
