Read and search Codex CLI and Claude Code chat history from the terminal.

agent-chat-reader

Read and search Codex CLI and Claude Code chat history from the terminal.

Useful for AI agents that need to recall what was discussed or decided in past sessions, without manually parsing noisy JSONL files.

Install

uv tool install agent-chat-reader

Or for development:

git clone https://github.com/alik-git/agent-chat-reader
cd agent-chat-reader
uv sync --extra dev
uv run agent-chat-reader --help

Usage

List recent sessions (both Codex and Claude Code, sorted by recency):

agent-chat-reader --list

Search across all sessions for a keyword:

agent-chat-reader --find "sim2sim"
agent-chat-reader --find "policy_interface" --source codex

Read a specific session by UUID prefix:

agent-chat-reader 019eaecb
agent-chat-reader 1bfc739b --verbose     # include tool call summaries
agent-chat-reader 019eaecb --tail 5      # last 5 user turns only

What it filters out

The raw JSONL files are very noisy. This tool extracts only:

• Codex: user_message events, agent_message events, and full response_item assistant text. Guardian/subagent sessions (auto-approval bots) are hidden by default.
• Claude Code: real user turns (not tool-result carriers), and assistant text blocks (not thinking blocks or tool calls). Sidechain sub-agent turns are hidden by default.

Use --include-subagents to see everything.
