claude-tap is a local proxy and trace viewer for AI coding agents. Run your CLI through it, or listen to local app transcripts, then inspect the real API traffic and agent context: system prompts, conversation history, tool schemas, tool calls, streaming responses, token usage, and request diffs.

Built with claude-tap

      Phistory archives versioned system prompt snapshots from agent CLIs such as Claude Code, Codex, Kimi, opencode, and Pi. It uses claude-tap's capture-only prompt export to preserve raw HTTP trace evidence and generate comparison-friendly prompt snapshots.

Why use it

- 👀 See the exact context: inspect prompts, messages, tool definitions, tool calls, tool results, reconstructed streaming responses, and token usage.
- 🔎 Debug behavior with evidence: compare adjacent requests and pinpoint which prompt, message, tool, or parameter changed.
- 📦 Share one portable artifact: each run writes a local trace session that can be exported to a self-contained HTML viewer for review or archiving.
- 🔒 Keep traces on your machine: no hosted dashboard is required, and common auth headers are redacted before recording.
- 🧩 Use one workflow across clients: trace Claude Code, Codex CLI, Codex App, Gemini CLI,…
