agent-trace-lite records simple agent spans and events to JSONL and summarizes durations and errors.

• Trace summaries now include first timestamp, last timestamp, and wall-clock runtime.
• summary --format markdown emits a paste-ready Markdown table for issues, PRs, and release notes.

python -m pip install .

agent-trace-lite start trace.jsonl plan
agent-trace-lite event trace.jsonl tool_call --message "ran command"
agent-trace-lite end trace.jsonl SPAN_ID --status ok
agent-trace-lite summary trace.jsonl --format json
agent-trace-lite summary trace.jsonl --format markdown

Record types:

• span_start: span id, name, timestamp, optional parent id
• event: name, timestamp, level, optional message and span id
• span_end: span id, status, timestamp, and duration when the start record is present
