Feature request: support viewing Claude Code session logs

[ddhjy]

Summary

Euphony currently supports Harmony conversations and Codex session JSONL files, but it does not appear to support Claude Code session logs yet.

From the current codebase and README:

• The README advertises Harmony and Codex session viewing.
• Session detection is wired through a Codex-specific parser.
• The parser recognizes Codex event shapes such as session_meta, response_item, event_msg, and turn_context.

Because of that, Claude Code session files seem likely to fall back to raw JSON rendering instead of the structured session timeline that Codex logs get.

Request

Please consider adding support for Claude Code session display, ideally with the same kind of structured timeline / conversation view that Codex sessions already have.

Why this would help

• Many people compare or debug workflows across multiple coding agents, not just Codex.
• Euphony already has a nice session-viewing UX, so extending that to Claude Code would make it more broadly useful.
• Even a basic first pass (messages, tool calls, tool outputs, timestamps) would already be very valuable.

Possible implementation direction

• Add a Claude Code session detector alongside the existing Codex detector.
• Normalize Claude Code events into the same internal conversation/message model used by the existing viewer.
• If possible, keep the session adapter layer generic so future agent/session formats can plug in more easily.

If helpful, I can also provide a sample Claude Code session file format for testing.

I found the euphony today and still exploring how it can be setup in my local machine to trace Codex sessions

For Claude Code, I have built the tracer for myself but somehow it got many stars, you can use https://github.com/delexw/claude-code-trace as an option

Claude Code session fields are significantly more complex than Codex's, so I wouldn't expect OpenAI to merge or implement this anytime soon.

I've had this exact need for a while — I previously used Poirot to inspect sessions and distill them into my own notes. But today, inspired by this project, I thought: why not build my own version?

If you're interested, here's what I've put together so far — features are still limited, but I'll be iterating on it over time: https://github.com/dawushi97/Prism
