Cctrace | Agent Skills Atlas

About this skill

Trace, inspect, and replay Claude Code's HTTP traffic with cctrace — a TLS-intercepting tracer with a live web UI. Use this skill whenever the user wants to see what Claude Code sends over the wire (system prompts, tools, token usage, cache hits, cost, usage limits, errors), debug a Claude Code session ("why did it do that", "what did the agent see", "why is my cache hit rate low", "how much did that session cost"), capture API traffic for a bug report, replay or share a captured session, work with saved .jsonl traces (view, clean, merge, compress), or find which port a running cctrace instance is on. Also use it when the user mentions cctrace, trace files in a .cctrace/ directory, MITM-capturing Claude traffic, tracing a third-party ANTHROPICBASEURL provider, or tracing the codex / grok / kimi CLIs.
