Consolidate or clarify the dual pytest invocations.
Line 38 already runs the full test suite, which would include tests/test_gh_cli.py. Line 43 repeats just that file with -q, making the check list slower without clear benefit. Either remove line 43 if the full suite covers it, or add a brief comment explaining why the focused run is needed (e.g., "quick smoke for gh_cli changes").
If kept, consider swapping order so the faster targeted run comes first.

Handle missing gh on the --fix path.
_run_gh still lets FileNotFoundError escape, so --fix will raise a traceback instead of the standardized missing-gh RuntimeError that the new shared helper returns for live read-only commands.

Add a timeout regression for the new helper.
run_gh has a dedicated TimeoutExpired → RuntimeError path, but this suite never exercises it. That leaves one of the new negative paths unproven. As per coding guidelines, "Add or update tests for changed behavior." As per path instructions, "Focus on whether tests prove the changed behavior and include negative, replay, boundary, or regression cases where relevant."

This still does not implement the stated shared-helper scope. The PR body says it adds scripts/gh_cli.py and tests/test_gh_cli.py, but the current diff only rewrites scripts/check_bounty_issue_states.py, scripts/check_live_bounty_closing_refs.py, and scripts/pr_queue_health.py; there is no shared helper module or targeted helper test. The changed scripts still keep local subprocess.run wrappers, and the hosted quality/readiness check is failing.
Please add the shared read-only gh helper and its tests, then migrate the scripts to call that helper with a focused diff.

Reviewed current head 8e0fa266e1058b277dc1ca95f8133dc5109ab95f. This still needs changes before merge.
The focused tests pass, but the current diff does not satisfy #1140's stated acceptance scope yet:
-
No existing maintenance script adopts the new helper on this head. The diff only adds
scripts/gh_cli.py,scripts/public_json_fetch.py,scripts/source_args.py, and two test files. The issue asks for "a shared helper" plus "at least some current duplicated maintenance scripts adopt it". Current source still has local wrappers in representative scripts such asscripts/check_bounty_issue_states.py,scripts/check_live_bounty_closing_refs.py,scripts/pr_queue_health.py,scripts/claim_inventory.py,scripts/proposed_work_triage.py,scripts/review_bounty_candidates.py, andscripts/submission_quality_gate.py. -
The read-only guard is incomplete for
gh api.gh apiswitches toPOSTautomatically when parameters are added, and GitHub's own help givesgh api repos/{owner}/{repo}/issues/123/comments -f body='Hi from CLI'as a comment-posting example. On this head,assert_read_only_gh_command()still allows these mutating forms:
['gh', 'api', 'repos/x/y/issues', '-f', 'title=test']['gh', 'api', 'repos/x/y/issues', '--field', 'title=test']['gh', 'api', 'repos/x/y/issues', '--raw-field', 'title=test']['gh', 'api', 'repos/x/y/issues', '--method=POST']['gh', 'api', 'repos/x/y/issues', '-XPOST']
It only rejects the split-token form --method POST. A shared read-only helper should either reject payload-bearing gh api flags unless --method GET is explicit, and handle combined method forms, or avoid advertising the helper as read-only enforcement.
Validation run:
python -m pytest tests\test_gh_cli.py tests\test_public_json_fetch.py -q-> 11 passed.python -m ruff check scripts\gh_cli.py scripts\public_json_fetch.py scripts\source_args.py tests\test_gh_cli.py tests\test_public_json_fetch.py-> passed.python -m ruff format --check scripts\gh_cli.py scripts\public_json_fetch.py scripts\source_args.py tests\test_gh_cli.py tests\test_public_json_fetch.py-> passed.git diff --check origin/main...HEAD-> clean.
Please migrate a small representative set of existing scripts to the helper, and tighten the gh api read-only enforcement/tests before merge.

🔒 Security & Privacy | 🔴 Critical | 🏗️ Heavy lift
Enforce gh command prefix and allowlist read-only shapes.
assert_read_only_gh_command does not verify that the executable is gh. Calling run_gh(["rm", "-rf", "/"]) executes successfully because it bypasses the narrow blocklist.
Additionally, the blocklist approach has two major flaws:
- It misses mutating commands outside the
issueandprscopes (e.g.,gh repo delete). - It incorrectly scans all arguments, meaning safe read-only queries like
gh issue list --label closewill crash because"close"is inargs.
Require args[0] == "gh" and validate the subcommand structure against a strict allowlist.

Restrict URL scheme to HTTP(S).

Handle UnicodeDecodeError from invalid payloads.
If the endpoint returns a payload with invalid UTF-8 bytes, .decode("utf-8") will raise a UnicodeDecodeError that escapes the current exception-handling blocks and crashes the script. Pass the raw bytes directly to json.loads (which natively handles byte decoding) and catch UnicodeDecodeError alongside JSONDecodeError to properly wrap the error.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Maintain strict whitespace validation contract.
As shown in scripts/review_bounty_candidates.py (Context Snippet 1), the upstream contract explicitly errors if leading or trailing whitespace is present, rather than silently stripping it. Silently dropping this strictness in the shared helper changes the behavior and relaxes the existing validation.
Caching the stripped value also avoids a redundant .strip() call.
Proposed fix
def _require_non_empty(
parser: argparse.ArgumentParser, value: str | None, *, label: str
) -> str:
- if value is None or not value.strip():
- parser.error(f"{label} must not be empty or whitespace-only")
- return value.strip()
+ if value is None:
+ parser.error(f"{label} must not be empty or whitespace-only")
+ stripped = value.strip()
+ if not stripped:
+ parser.error(f"{label} must not be empty or whitespace-only")
+ if stripped != value:
+ parser.error(f"{label} must not include leading or trailing whitespace")
+ return stripped📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Leverage argparse native mutual exclusivity.
Re-implementing mutual exclusivity and required-group logic manually bypasses argparse.add_mutually_exclusive_group(required=True). Using the built-in feature automatically formats the CLI --help text to show the (--input | --repo) constraint and handles these validation errors natively before reaching this helper function.
If the parsers in the calling scripts aren't already using mutually exclusive groups, consider configuring them there and removing this redundant check.

Test the TimeoutExpired exception path.
The TimeoutExpired exception handling in run_gh remains untested. As per coding guidelines, "Add or update tests for changed behavior", and as per path instructions, focus on proving changed behavior including "negative... cases where relevant".

Complete negative-path coverage for the helper.
The suite does not exercise CalledProcessError, malformed JSON, or run_gh_json_list/run_gh_json_object rejecting the wrong top-level shape. Add focused tests that assert the wrapped exit code/stdout/stderr and the expected JSON validation errors.
As per coding guidelines, “Add or update tests for changed behavior”; as per path instructions, focus on negative and regression cases where relevant.

Cover UTF-8 decoding and header overrides.
The success payload is ASCII-only, so it does not prove UTF-8 decoding. Add a non-ASCII payload using ensure_ascii=False, and assert custom accept and user_agent values reach the request.

Reviewed current head ce921a2. Changes are still required before merge: scripts/gh_cli.py does not require args[0] == 'gh', so run_gh can execute an arbitrary non-gh program, and its narrow blocklist still permits mutating shapes such as gh repo delete, gh workflow run, and gh api parameter flags that default the request to POST. The new commits are formatting/import-order changes and do not close this read-only enforcement gap. Please replace the blocklist with a strict allowlist for supported read-only gh command shapes and add regression coverage for non-gh executables, mutating top-level commands, parameterized API calls, repeated method flags, and safe option values such as --label close.
