Troubleshooting — I see no data

Run the built-in diagnostic:

Visit http://localhost:7842/api/debug in your browser after starting TokenWatch. It checks:

• Whether your Claude Code log directory exists
• Whether session files are present
• Whether the log format is readable
• What the most recent session contains

Common fixes:

Problem	Fix
"No .jsonl files found"	Run claude in a project folder first, then refresh
"Claude projects directory not found"	Claude Code hasn't been used yet on this machine
Dashboard shows $0.00	Your session has no usage data — check the diagnostic
Numbers look wrong	Click ↺ Refresh on the prices panel to fetch live rates

How it works

Claude Code writes JSONL session logs to ~/.claude/projects/<project>/<session>.jsonl. TokenWatch watches that directory with OS-native file events, reads new entries within 300ms, and streams cost updates to the dashboard via Server-Sent Events.

Costs = token counts × live Anthropic prices (fetched from LiteLLM's community-maintained price list).
