7979Run [`/insights`](/docs/en/commands#all-commands) for a report on how you work rather than how many tokens you've used. It analyzes your recent sessions on this machine and writes an HTML report covering what you work on, friction points such as misunderstood requests or buggy code, and suggestions for using Claude Code more effectively. A single run analyzes up to 200 sessions it hasn't seen before and skips very short ones. When sessions are left out, the report header shows the analyzed count with the total in parentheses, for example `200 sessions (412 total)`.

81When [auto mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) is available to the session and your recent sessions mostly ran without it, the report can also include an estimate of how many permission prompts auto mode could have handled across those sessions.

8183Claude Code writes the latest report to `~/.claude/usage-data/report.html` and saves a timestamped copy of each run in the same directory, so earlier reports aren't overwritten. Claude Code deletes reports on the same schedule as the rest of your session data: at startup, it removes files older than [`cleanupPeriodDays`](/docs/en/claude-directory#cleaned-up-automatically), 30 days by default.

8385You can run `/insights` on any plan and with any provider. The analysis runs through the same provider and account as your regular sessions, and the tokens count against your plan or API usage. Sessions from other devices and claude.ai aren't included.
