Add a PreToolUse hook that blocks any GitHub or Jira comment posted by Claude Code whose body is missing the "via Claude Code" attribution. Covers gh pr comment, gh issue comment, gh pr review, gh api comment calls, and the Jira addCommentToJiraIssue MCP tool. Broaden the AGENTS.md attribution rule to name GitHub PRs and issues, not just Jira, and point to the hook as the enforcement mechanism. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Purpose of this pull request
Every comment Claude Code posts is supposed to end with the
via Claude Codeattribution, but theAGENTS.mdrule was scoped to Jira only and is a soft instruction, so GitHub PR and issue comments were attributed only intermittently.This PR makes it deterministic:
.claude/settings.json(new, team-wide) registers aPreToolUsehook onBashand the Jira comment MCP tool..claude/hooks/require-claude-attribution.sh(new) blocksgh pr comment,gh issue comment,gh pr review,gh apicomment calls, andmcp__atlassian__addCommentToJiraIssuewhen the body does not containvia Claude Code(case-insensitive), and tells Claude to repost with the marker. File-body (--body-file) calls pass through since the content is not visible; malformed hook input fails open.AGENTS.mdattribution rule broadened to cover GitHub PRs and issues, pointing at the hook as the enforcement mechanism.The hook is run by the Claude Code harness, not the model, so it fires every time.
