Project ideas from Hacker News discussions.

Show HN: Geiger – See every AI agent on your machine and what it can touch

📝 Discussion Summary (Click to expand)

Theme 1 – Sandboxing/isolating AI agents is essential to avoid system damage
- “If this tool is returning even a single hit from this, you're probably using these agents wrong. You really want to run these in a way so they cannot touch your system drive/general filesystem that you use to do real work on.” – embedding-shape
- “≈nobody is sandboxing their agents/harnesses in practice. Or at least, a good majority isn’t.” – msdz
- “I run it on a physically dedicated machine … I don't do it for security reasons, I just want it to run when my laptop is closed …” – Muromec

Theme 2 – Human fatigue leads to weakening security controls over time
- “You start really locked down… you stop reading as closely… you start feeling silly… you slowly start to give your agents more access with fewer review steps.” – cortesoft
- “I know plenty of frontend engineers that without blinking run 'npm install' on random 3rd party projects … but then again, I also know people … who have unprotected sex with prostitutes, so maybe something makes me slightly biased here.” – embedding-shape (illustrating disregard for safety)
- “There are a ton of people who are stupid enough to disregard all kind of safety precautions. That doesn't mean the safety precautions are invalid though.” – bigstrat2003

Theme 3 – Practical mitigations and observations help reduce risk
- “The trick is not go to that limit, but stay under 50% or even better 25% of context length. But backups are a smart thing anyway.” – lukan
- “Wes McKinney has a project for agent visibility: https://www.agentsview.io/” – dpflan (monitoring tool)
- “I've never had any of the GPT models do anything of the sorts when using the higher reasoning efforts… sometimes when I play around with local models … they forgets/misses to define $ID then do 'rm -rf data/$ID'.” – embedding-shape (model/reasoning effort matters)

AgentScope Inventory CLI

Summary

  • Scans the host for AI agents, MCP servers, plugins, extensions and lists them with metadata such as version, last activity, and sandbox status.
  • Provides read‑only observability to surface shadow AI usage and reduce manual approval fatigue.

Details

Key Value
Target Audience Developers, DevOps, and security teams running local AI agent harnesses
Core Feature Discover and inventory AI components via filesystem/introspection, output as JSON or table
Tech Stack Rust (or Go) for fast, safe scanning; optional SQLite for caching
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters asked for “One read-only command that inventories every AI agent, harness, MCP server, plugin, and AI extension on a machine” (embedding‑shape).
  • Enables governance and shadow‑AI detection, sparking discussion on observability tools for AI workloads.

AgentSandbox Manager

Summary

  • Launches AI agents in lightweight sandboxed environments (containers/user namespaces) with restricted filesystem access.
  • Provides a just‑in‑time approval UI to reduce manual fatigue while maintaining security.

Details

Key Value
Target Audience AI developers and power users who run agents locally
Core Feature Policy‑driven sandbox creation (Firejail/bubblewrap/gVisor) plus an approval workflow UI
Tech Stack Electron/Tauri desktop UI, backend in Go/Rust, OCI runtimes for sandboxing
Difficulty High
Monetization Revenue-ready: Subscription per user tier

Notes

  • Commenters expressed frustration with manual approval cycles and a desire to sandbox agents (cortesoft, embedding‑shape).
  • Offers a concrete solution to reduce fatigue and prevent accidental destructive commands, likely to generate discussion on security UX.

AgentMood Dashboard

Summary

  • Real‑time visual dashboard showing each agent’s state, mood (emoji), resource usage, and alerts for risky actions like file deletions.
  • Integrates with agent harness logs to surface behavior and provide early warnings.

Details

Key Value
Target Audience AI developers and operators seeking visibility into agent behavior
Core Feature Aggregate logs, display emoji faces, metrics, and risk alerts in a UI
Tech Stack React frontend, Node.js/WebSocket backend, log storage via Loki or Elasticsearch
Difficulty Medium
Monetization Hobby

Notes

  • Muromec wanted a pixel‑display to show emoji faces of agents; this fulfills that desire.
  • Provides intuitive feedback that could reduce oversight fatigue and spark conversation about agent transparency.
