Conversation
claude-verify only reports on auto-merge-labeled prs; requiring it as a branch-protection check would block every normal unlabeled pr from merging. the label flow still gates on it via the arm-needs-verify job dependency in auto-merge.yml, so the veto holds without blocking manual merges.
drop the author_association==OWNER guard so the owner can authorize a contributor PR by labeling it, not just their own PRs. the trusted-labeler check becomes the primary authorization gate and now strips the label if an untrusted actor applies it, so a stray label cannot persist and bypass the check on a later synchronize event.
a push to a labeled pr previously re-entered the pipeline on synchronize without re-checking the labeler, so a contributor could get a benign commit labeled and then push malicious code that verify would check out and run with the anthropic key + write token (pull_request_target rce). now synchronize only runs a deauthorize job that disables auto-merge, removes the label, and comments — it never checks out head. verification re-runs only on a fresh owner label. also scope permissions per job (deny-all default; verify gets no contents:write since untrusted code runs there) and pin verify to the labeled head sha.
learned from openclaw/openclaw's pr-merge tooling and applied the transferable practices: - pin every third-party action to a commit sha (checkout, setup-python, claude-code-action) so a moved tag cannot inject code. - add a workflow-lint gate running zizmor (security) + actionlint (correctness) on every workflow change, openclaw's signature practice. - annotate the deliberate pull_request_target / workflow_run triggers with justified `# zizmor: ignore[dangerous-triggers]` comments. - set persist-credentials: false on the untrusted-head checkout in the verify job so contributor code cannot read the token from .git/config. - add concurrency/supersede on auto-merge so a newer event cancels an in-flight run. - .github/zizmor.yml disables the pin/permissions-migration audits repo-wide (same stance as openclaw) so the gate does not require migrating every older workflow at once; labeler + release get justified inline ignores.
…eset - extract verify + arm into a reusable pr-verify.yml shared by the label path and the new slash-command path (avoids github label-recursion). - #2 environment gate: the verify job runs behind a pr-verify environment with a required-reviewer rule, so untrusted head code and the api key are gated on the owner per-run approval. the key is passed explicitly to the handler, not inherited. - #3 comment-command.yml: the owner authorizes a pr by commenting /auto-merge or /verify (owner-gated), as an alternative to the label. - #1 setup_repo_guards.sh replaces setup_branch_protection.sh: creates a branch ruleset (pr + code-owner review + ci/trust-gate checks, org-admin bypass) plus the pr-verify environment and the labels. - deauthorize-on-push now runs on every synchronize (unconditional disarm).

Require claude-verify in the auto-merge ruleset
gh pr merge --auto can still merge the current head after a new push unless claude-verify is a required check. scripts/setup_repo_guards.sh:59-62 only requires test (py3.11/py3.12/py3.13), build sdist + wheel, and trust-gate, so the deauthorize-on-push workflow still leaves a race. Add claude-verify to the required status checks for auto-merge PRs.

zizmor 1.27.0 --persona regular CLI help docs
💡 Result:
Zizmor is a static analysis tool for GitHub Actions designed to identify and fix security issues within CI/CD configurations [1][2]. As of version 1.27.0, the tool does not feature a "--persona" command-line option [3][4]. The standard CLI usage for zizmor involves auditing local directories, specific workflow files, or remote repositories [3]. You can access the official help documentation by running the following command in your terminal: zizmor --help For detailed usage information, including input collection, operating modes, and configuration, you can refer to the official documentation at https://docs.zizmor.sh/ [5][6]. The current version, 1.27.0, was released in July 2026 [7]. If you were looking for specific functionality related to how the tool audits your files, you may want to use the --collect option to specify which input kinds (such as workflows, actions, or dependabot configurations) should be analyzed [3][4].
