The score comes from our model.

• Show HN: An agent harness for long-running pentests and code audits · score 7.5

  Vigil is an AI harness that coordinates agent clients like Claude Code and Codex to perform long-running security audits and pentests. It orchestrates multi-pass investigations, maintains findings across sessions, and includes runtime reproduction and evidence tracking. The project demonstrates real-world utility, having been used to reach top ranks on HackerOne.

• Show HN: Friday, an open-source harness for coding agents that work as a team · score 7.0

  Friday is an open-source harness that orchestrates multiple coding agents (Claude Code, Codex, Cursor, Gemini CLI, Copilot, and others) as a team within a shared session. Agents collaborate via a task board, message each other, work in isolated repo copies, and hand off tasks when usage limits hit, with a human review step before changes land. It's interesting for treating heterogeneous AI coding CLIs as cooperating workers rather than isolated tools.

• Show HN: Hlock – an agent harness lockfile and performance resolver · score 7.0

  hlock is a lockfile and performance resolver for AI agent harnesses, pinning models, MCP servers, skills, and config into a portable harness.lock that can be versioned and rehydrated anywhere. It also benchmarks and optimizes your agent stack against eval packs to find the best combination of success rate, cost, and latency. The project stands out by treating agent setups as reproducible dependencies, similar to package managers but for the entire agent harness.

• Show HN: Endo – A Higher-Order Harness · score 7.0

  Endo is a higher-order harness that composes multiple AI agents (Codex, Claude Code, Antigravity, Grok) into unified workflows using existing subscriptions. It enables mid-thread agent switching, parallel fan-out, and persistent sessions, making it a flexible desktop tool for agent orchestration.
