── AI DEEP ANALYSIS ──

reviewed by: nvidia/nemotron-3-super-120b-a12b

psc is a CLI tool that uses eBPF iterators to scan processes and file descriptors with Google CEL for filtering. It provides container context for processes by integrating with Docker, containerd, CRI-O, and Podman runtimes. The architecture is modular with separate packages for BPF data unmarshaling, container management, CEL filtering, and output formatting (table/tree). Key strengths include its efficient kernel-level access via eBPF, expressive CEL-based filtering, and intelligent container context propagation to child processes.

── KEY FINDINGS: REUSABLE CODE ──

The LLM identified 3 files worth highlighting for reuse:

A reusable CEL-based filtering system that registers Go types with CEL expressions, provides field extraction via reflection, and implements a MatchResult concept to track which file descriptors caused a process match. Demonstrates sophisticated use of the cel-go library and clean separation of concerns.

file: pkg/filter/ ↗ | tags: #cel-filtering #expression-engine #reflection-based-schema

A unified container runtime manager that abstracts over Docker, containerd, CRI-O, and Podman. Its standout feature is PID propagation to child processes, ensuring container context is visible for all processes in a container (not just the main process). Shows strong interface design and problem-solving.

file: pkg/containers/manager.go ↗ | tags: #container-abstraction #pid-propagation #runtime-agnostic

A clean implementation of a process tree data structure with printing capabilities. Well-integrated with container information and filtering capabilities. Demonstrates good tree algorithms and presentation logic.

file: pkg/tree/ ↗ | tags: #process-tree #hierarchical-display #container-integration
