 ### Subagent capabilities
 
 Subagents have: file operations, shell (for local git, tests, builds), read-only GitHub queries, and upload_file. They do NOT have: \`git\`, \`checkout_pr\`, \`push_branch\`, \`create_pull_request\`, \`create_pull_request_review\`, \`report_progress\`, \`create_issue_comment\`, \`reply_to_review_comment\`, \`resolve_review_thread\`, \`delegate\`, \`ask_question\`, or any dependency/remote-mutating tools. All GitHub-write and state-mutating operations are your responsibility.
