Documentation describes features not implemented in the script.
The documentation mentions "Issue/PR テンプレート有効化" (line 21), "Code scanning alerts 有効化" (line 25), and "Secret scanning 有効化" (line 26), but the script does not configure these features. The script only enables vulnerability alerts and automated security fixes, with a comment noting that code/secret scanning requires GitHub Advanced Security.

.claude/commands/setup-team-protection.md lines 21-27: the doc lists "Issue/PR
テンプレート有効化", "Code scanning alerts 有効化", and "Secret scanning 有効化" but the script
only enables vulnerability alerts and automated security fixes; either update
the documentation to accurately reflect what the script does (remove or mark
those three items as not implemented and note that code/secret scanning require
GitHub Advanced Security and that Issue/PR templates must be added to
.github/ISSUE_TEMPLATE and .github/PULL_REQUEST_TEMPLATE), or implement the
features in the script (add steps to create template files for Issue/PR
templates and call GitHub APIs to enable code & secret scanning if running under
an org with GitHub Advanced Security). Make the change by editing the markdown
to state the current implemented features and clearly mark unimplemented items
with guidance on how to enable them and prerequisites.

Missing input validation for --reviewers argument.
The --reviewers value is used directly without validating that it's a positive integer. Invalid values (e.g., negative numbers, non-numeric strings) would cause confusing API errors later.

In script/setup-team-protection.sh around lines 50 to 53, the --reviewers branch
assigns REVIEWERS="$2" without validating it; add input validation immediately
after the assignment to ensure REVIEWERS is a positive integer (e.g., check with
a regex like '^[1-9][0-9]*$' or use a numeric comparison), and if the value is
invalid print a clear error to stderr and exit with a non-zero code so invalid
inputs are rejected before any API calls.

Hardcoded assumption that main branch exists for creating new branches.
When --create-branches is used, the script always derives the new branch from main (line 169). If the repository uses a different default branch (e.g., master), or if main doesn't exist yet, this will silently fail due to || true.
🔎 Proposed fix - use repository default branch
if [[ "$CREATE_BRANCHES" == "true" ]]; then
warning "Branch $branch does not exist. Creating..."
+ DEFAULT_BRANCH=$(gh api "repos/$REPO" --jq '.default_branch' 2>/dev/null || echo "main")

In script/setup-team-protection.sh around lines 162 to 175, the code assumes
"main" exists when creating new branches; instead fetch the repository's default
branch (gh api repos/$REPO --jq '.default_branch'), use that branch's tip SHA as
the base when creating refs, and remove the silent "|| true" so failures
surface; if determining the default branch or fetching its SHA fails, emit a
clear error and return non-zero.

GitHub REST API branch protection PUT endpoint allow_force_pushes schema
💡 Result:
Short answer:
-
Request (PUT /repos/{owner}/{repo}/branches/{branch}/protection) body: allow_force_pushes — boolean or null. Set true to permit force pushes, false or null to block them. Default: false. [1]
-
Response (GET /repos/{owner}/{repo}/branches/{branch}/protection) schema: allow_force_pushes is an object with an enabled boolean, e.g. "allow_force_pushes": { "enabled": true }. [1][2]
Sources: [1] GitHub Docs — REST API: Branch protection (Update/Get branch protection). [2] Example response schema (branch protection) showing allow_force_pushes object.

Fix branch protection API payload schema: allow_force_pushes, allow_deletions, and required_linear_history should be booleans, not nested objects.
Lines 203–205 use the GitHub API response schema format ({"enabled":false}) but the PUT request expects direct boolean values (false). This will cause the API call to fail or behave unexpectedly.
Update:
"allow_force_pushes":false(not{"enabled":false})"allow_deletions":false(not{"enabled":false})"required_linear_history":false(not{"enabled":false})
Additionally, consider using jq instead of manual string concatenation to make JSON construction safer and less error-prone.
🤖 Prompt for AI Agents
In script/setup-team-protection.sh around lines 203 to 206, the branch
protection JSON currently uses nested objects like
"allow_force_pushes":{"enabled":false} etc., but the PUT API expects direct
boolean values; change those entries to "allow_force_pushes":false,
"allow_deletions":false, and "required_linear_history":false. Update the string
concatenation that builds protection_config accordingly (or replace the manual
construction with a jq-based JSON build to avoid quoting/escaping errors) so the
final payload contains the boolean fields directly rather than objects.
