How does each harness find code it has not read yet?

Present but not verified. 24 more harnesses register a code search tool that has not been read from source: Claude Code Glob, Claude Code Grep, Codex exec_command, dsh glob, dsh grep, Grok Build grep, Grok Build list_dir, Hermes search_files, Kimi Code glob, Kimi Code grep, MiMo Code codesearch, MiMo Code glob, MiMo Code grep, OpenClaw exec, opencode glob, opencode grep, OpenHands glob, OpenHands grep, pi find, pi grep, Qwen Code glob, Qwen Code grep_search, ZCode Glob, ZCode Grep. They are left out of the table below rather than shown as empty rows — a blank cell would claim the behaviour is absent, which is a different thing from not having checked.
