Update the Codex tool mapping so Claude Code 'Task returns result' maps to the current Codex spawned-agent result tool, wait_agent. Also clarify that older Codex builds exposed spawned-agent waiting as wait, while current bare wait is the code-mode exec/wait surface for yielded exec cells.
Verified with Drill:
- codex-tool-mapping-comprehension fails against dev with task_returns_result=wait
- codex-tool-mapping-comprehension passes against this PR with task_returns_result=wait_agent and exec/wait scoped correctly
- codex-subagent-wait-mapping passes against this PR with spawn_agent -> wait_agent -> close_agent and PR963_OK returned
Maps all Claude Code tool names to Gemini CLI equivalents (read_file,
write_file, replace, run_shell_command, grep_search, glob, write_todos,
activate_skill, etc.). Notes that Gemini CLI has no subagent support.
Updates using-superpowers to reference GEMINI.md in instruction priority
and link to the new gemini-tools.md reference alongside codex-tools.md.
