…(LSA-191) Lefthook - Add lefthook.yml with a piped pre-commit hook - Skip the hook during merges and rebases - Ignore lefthook-local.yml for personal overrides PHP check job - Run php -l on each staged PHP file, then phpcs on the staged files - Errors block the commit, warnings do not - Skip build/ and vendor/ files - Fail with a clear message if php or phpcs is missing Build job - Run npm run build when files in src/ or webpack.config.cjs are staged - Stage the whole build/ folder, as webpack runs with clean: true - Stop if src/ has unstaged changes or untracked files - Block git commit <file>, which drops staged files from the real index - Fail with a clear message if npm or node_modules is missing PHP ruleset - Add phpcs.xml.dist for PHP files only, skipping vendor, node_modules and build - Switch off 13 auto-fixable formatting sniffs the existing code breaks - Report 8 judgement-call findings as warnings - Keep security sniffs on, excluding two false positives for one file each - Existing code now has 0 errors and 70 warnings Composer and dependencies - Point the phpcs and phpcbf scripts at the ruleset, fixing the out-of-memory crash - Add lefthook as a devDependency and update package-lock.json Docs - Add .github/reports/lefthook-setup.md with install, usage, bypass, limits and verification - Add the CHANGELOG entries under Unreleased Verification - 24 real git commit scenarios in a scratch worktree: valid, blocked and edge cases - A pure rebuild gives no difference from the committed build/ - composer run phpcs, phplint, plugin:validate, schema:validate and security:scan pass - npm audit is unchanged at 122 findings

The ruleset scans PHP files, excludes generated and dependency directories, configures WordPress checks, and separates warnings from security errors. Composer scripts use the default ruleset discovery. Existing PHPCS suppressions document handled output and sanitization cases. |
Pre-commit validation and build staging lefthook.yml, package.json, .gitignore, .github/reports/lefthook-setup.md, CHANGELOG.md |
Lefthook runs staged PHP checks and guarded build generation. The package adds Lefthook, .gitignore excludes local override files, and the documentation and changelog describe setup, guards, bypasses, verification, and removal. |

The hook can skip rebuilding when a commit only deletes source files, which can leave outdated generated files in build/. This is a bounded developer-workflow inconsistency, not a runtime failure. Consider fixing it before or shortly after merge.

- Around line 41-44: Update the build job in lefthook.yml to remove its glob
filters and guard execution with a cached-diff check for src and
webpack.config.cjs, exiting successfully when neither has staged changes so
deletions still trigger the clean webpack build. Remove the outdated limitation
documentation and add a commit test covering a source deletion.
Review comments at @phpcs.xml.dist:
- Around line 85-89: Replace the file-wide exclusions for render.php and
class-permalinks.php with precise inline suppressions at only the existing
documented false-positive statements, and correct the
ValidatedSanitizedInput.InputNotSanitized sniff name for class-permalinks.php.

41-44: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winRun the build job for deletion-only commits.
Lefthook filters deleted paths out of the file list before it applies
glob. A commit that only deletes files undersrc/can skip thebuildjob. Withclean: true, stale output for the deleted source can then stay inbuild/. The setup doc (lines 51 and 107) says deletions trigger the job. Theglobfilter may contradict this claim.Run the job without
glob. Exit early when the staged diff has no changes undersrcorwebpack.config.cjs. This keeps behavior for other commits the same.Proposed change
- name: build - glob: - - "src/*" - - "src/**/*" - - "webpack.config.cjs" run: | + if git diff --cached --quiet -- src webpack.config.cjs; then + exit 0 + fiTest with a deletion-only commit. This is a duplicate of an earlier review comment.

@brandonmarshal i took at look and i approve. I see the data-wp-context outputs dont need to be sanitized but product a false positive.

@krugazul yes, those two lines output markup that WordPress already escapes, so PHPCS flags them by mistake. I’ve marked just those two lines with a short ignore and a reason, the same way the taxonomy-filter block already does, so the rest of the file is still checked. 🙂 |

Part of Linear LSA-191 (Set up Lefthook validation for the theme and plugin). This PR covers the plugin's first two checks only. The theme's matching PR is lightspeedwp/ls-theme#128. The remaining validation categories in LSA-191 are still open, so this PR does not use a closing keyword. There is no GitHub issue for LSA-191 in this repository.
Summary
Git hooks are not set up in this repo.
build/is committed and is what PHP loads, so a source change can be committed with stale built output, and PHP can reach a PR with syntax or coding-standard errors. Lefthook now runs apre-commithook with two jobs. It is installed as an npm devDependency, sonpm installsets the hook up for every contributor.The hook
lefthook.ymldefines onepre-commithook. Its jobs run in order (piped) and are skipped during merges and rebases.src/skips both.Job 1:
php-check*.php(notbuild/orvendor/). It runsphp -lon each staged file, thenvendor/bin/phpcson the staged files. Errors block the commit; warnings do not.phpis not on thePATHorphpcsis not installed.Job 2:
buildsrc/**orwebpack.config.cjs. It runsnpm run build, then stagesbuild/, so source and built output are committed together.webpack.config.cjssetsclean: true, sobuild/is entirely generated and the whole folder is staged, including files the build no longer produces. A rebuild with no source change gives no difference from the committedbuild/.src/(orwebpack.config.cjs) has unstaged changes, or when there are untracked files undersrc/.npm run buildcompiles the whole working tree, so otherwisebuild/could be staged with output from a file that is not in the commit.git commit <file>(and--only). Git runs hooks for those against a temporary index, so the stagedbuild/would be committed and then dropped from the real index, leaving a staged revert. Plaingit commit,-a,--includeand--amendwork.PHP ruleset (

The old command also read JavaScript and CSS, including the 154 KB minified Swiper bundle inassets/, and ran out of memory (128 MB limit). The whole repo now checks in about 1.5 seconds.

Worked around in the ruleset. Fixing the comment would be a source change.Scope and exclusions
pre-pushhook.build/file.package-lock.json(184 lines added, 42 removed) is excluded from the count, leaving 7 reviewable files and 294 added lines (114 of them the setup report). This is within the preferred budget of about 15 files / 400 lines.Screenshots / video
None. There is no visible or UI change; the only output is terminal messages from the hook.
