Harness²
Google Research
Google Research's open-source framework for recursive agent harnessing that refines an agent's prompts, tools and memory per task.
Key features
- Task-Level Recursion: A contrastive Propose-Probe-Compose step proposes edits, probes their effects on the same task and composes a refined harness without ground-truth feedback.
- Harnessing-Level Recursion: A persistent improvement harness is updated with adopted harnesses and evidence-supported lessons from each task.
- Eight Editable Components: Exposes system prompt, guardrails, memory, tool guidance, subagents, skills, scripts and plugins as tunable parts.
- Parallel and Sequential Modes: Scale the task-level recursion budget by exploring candidates in parallel or refining sequentially.
- Multiple Executors: Run refinement with OpenCode and Codex executors.
- Built-In Benchmarks: Setup and run commands for JobBench, LAB (legal work) and WorkBuddy Bench (office, web and code).
- Credential-Free Demo: A local demo with deterministic editors runs both recursion modes without model credentials.
Best for
- Agent Harness Research: Study how contrastive harness edits affect agent performance across benchmarks.
- Improving Base Agents: Raise results of models such as GLM 5 and Gemini 3.5 Flash over their default harnesses.
- Professional Task Evaluation: Evaluate agents on legal, office and coding tasks using bundled benchmark guides.
- Tuning Coding Agents: Refine system prompts, skills and subagents for OpenCode or Codex executors.
- Reproducible Experiments: Run, judge and report benchmark experiments with resume support.
Pip
Pip
Voice-driven AI buddy for macOS that sees your screen and points at exactly where to click in any app.
Key features
- On-Screen Pointing: Circles the exact button, panel or menu to click, so you stop hunting through menus.
- Voice Questions: Hold a key, ask out loud and let go; Pip answers in one spoken sentence with natural voice.
- Click-by-Click Guidance: Follows you through multi-step tasks, finding each next step locally on your Mac.
- Works in Any App: Reads the screen like you do, so it needs no per-app plug-in for settings, browsers, editors or design tools.
- Terminal Help: Shows the exact command to type and explains what it will do before you press return.
- Quick Mac Actions: Handles requests like timers, volume, dark mode, window layout, reminders, calendar and texts, confirming before sending or deleting.
- Terminal Voice Typing: Pro plan lets you talk to Claude Code or Codex in the terminal instead of typing.
- Privacy by Design: Only looks at the screen when you ask, and screenshots are not stored.
Best for
- Learning Pro Software: Getting hands-on guidance inside DaVinci Resolve, Photoshop or Figma while you work.
- Terminal Troubleshooting: Asking in plain words how to fix errors like a busy port and getting the command to run.
- Everyday Mac Help: Finding hidden settings or export options without searching documentation.
- Hands-Free Coding Input: Dictating prompts to Claude Code or Codex in the terminal.
- Onboarding Less Technical Users: Helping family members or new employees navigate unfamiliar apps.
- Personal Quick Tasks: Setting reminders, timers and window layouts by voice.
