agentsight CLAUDE.md

agentsight CLAUDE.md is an instructions file for Claude Code from eunomia-bpf/agentsight. It costs 2,524 tokens per session, scanned D, original, MIT.

Repository instructions for AgentSight, an eBPF-based monitoring system that observes AI-agent traffic and processes on Linux.

In plain words
What is it for?
Use them when changing AgentSight, especially when building eBPF programs, the Rust collector, the frontend, or their tests.
Why use it?
They give coding agents the project context and the commands needed to build and test its kernel, Rust, and frontend components.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

agentsight CLAUDE.md scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

sudo ./agentsight record -- claude

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

How it starts

The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to coding agents working in this repository. AGENTS.md is a symlink to this file so Claude Code and other agents share the same repository instructions.

Overview

AgentSight is an eBPF-based observability framework for monitoring AI agent behavior through SSL/TLS traffic interception and process monitoring. It captures unencrypted request/response data at the kernel level without requiring any code changes to target applications.

Build & Test Commands

# Full build (eBPF + Rust collector + frontend)
make build

# Individual components
make build-bpf                          # eBPF C programs only
cd collector && cargo build --release   # Rust collector only
cd frontend && npm install && npm run build  # Frontend only

# Tests
cd bpf && make test              # C unit + runtime tests
cd collector && cargo test       # Rust tests
cd frontend && npm run lint      # Frontend linting

# Run a single Rust test
cd collector && cargo test test_name

# Debug builds with AddressSanitizer
cd bpf && make debug
cd bpf && make sslsniff-debug

# Install system dependencies (Ubuntu/Debian)
make install

Running

# Live agent sessions
./agentsight top

# Launch and record a command
sudo ./agentsight record -- claude

# Record Claude Code (requires --binary-path for statically-linked BoringSSL)
sudo ./agentsight record -c claude --binary-path ~/.local/share/claude/versions/<version>

# Record Python AI tools
sudo ./agentsight record -c python

# Record with NVM Node.js (statically-linked OpenSSL)
sudo ./agentsight record -c node --binary-path ~/.nvm/versions/node/v20.0.0/bin/node

# Direct eBPF program usage
sudo ./bpf/sslsniff --binary-path <path>
sudo ./bpf/process -c python

# debug trace needs --server.

Documentation Hygiene

  • Keep the README Quick Start stable. Do not update Quick Start unless the primary onboarding command or first-run flow changes.
  • Put details about mode-specific behavior, persistence paths, storage formats, and operational caveats in Usage, FAQ, or dedicated docs sections instead of Quick Start.
  • When changing user-facing CLI behavior, update the focused reference docs and examples that describe that behavior, but avoid broad README churn.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agentsight CLAUDE.md is an instructions file published in the GitHub repository eunomia-bpf/agentsight (666 stars, last pushed yesterday), licensed MIT. It adds 2,524 tokens to every session, about $0.0126 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
