Intro

AgentSight is an MIT eBPF tool that records LLM/agent traffic without SDK changes, helping you observe Claude Code or Gemini CLI interactions locally.

Best for: developers who want local, low-overhead observability for agent tools without changing app code

Works with: Linux hosts with eBPF support, sudo privileges, Claude Code / Node / Python agent processes

Setup time: 10-15 minutes

Key facts (verified)

  • GitHub: 318 stars · 49 forks · pushed 2026-04-22.
  • License: MIT · owner avatar + repo URL verified via GitHub API.
  • README-verified entrypoint: docker run --privileged --pid=host --network=host \.

Main

  • Use it when instrumentation is too expensive: eBPF captures behavior at the system boundary without modifying your agent code.

  • Start by recording one process name (claude/node/python) and validate you can correlate events with failures or regressions.

  • Treat the trace as evidence: use it to debug latency spikes, unexpected network calls, or policy violations.

Source-backed notes

  • README states “Zero Instrumentation Required” and focuses on observing at the system boundary using eBPF.
  • README includes command examples to record Claude Code and gemini-cli processes via agentsight record -c ....
  • README suggests a local web UI at http://127.0.0.1:7395 for viewing recordings.

FAQ

  • Does it require code changes?: No—README emphasizes zero instrumentation.
  • Where does it run?: README examples target local processes on a host with sudo permissions.
  • Is it cross-platform?: It’s eBPF-based, so Linux support is the primary path (check README).
