README

Excerpt

Session Metrics

Runs scripts/session-metrics.py against the Claude Code JSONL log to produce a timeline-ordered cost summary with per-turn and cumulative totals.

Dispatch — how to route this invocation

First positional argument received: $ARGUMENTS[0] Full argument string: $ARGUMENTS

Read $ARGUMENTS[0] above and match it by literal equality against the table below. Claude Code already tokenized the arguments shell-style, so no parsing is required — just compare strings.

This is the opening of the README. Read the full README on GitHub.
