Built a skill today that reviews my pi agent sessions over any date range. Ran it on Feb 1–16. Here is what came out.

The Numbers

~360 messages a day. One terminal. 65 different projects. Client work, infrastructure, personal tools, finance, content.

This is only my pi agent. Not counting my OpenClaw instance, not counting Codex sub-agents. Just pi.

Where Time Goes

I spend almost as much time building skills (616) as building features (1,023). Every skill I build saves hours the following week. The system keeps building itself.

Feb 6

One day. 529 messages. 13 projects. 157 context switches.

• Built an analytics platform from scratch (Wachturm), deployed it
• Set up Tailscale private infrastructure, security reviewed
• Built a lead gen pipeline for a client. Apify scrapers into Supabase into Slack
• Cleaned up 1,500+ Readwise articles with auto-tagging
• Drafted client emails in German about invoice matching
• Analyzed December spending, migrated expense tracking to a new skill
• Deleted 20+ old GitHub repos
• Built 3 new skills
• Logged hours, posted weekly updates, did code reviews

One terminal. No app switching.

The Skill

About 400 lines of JavaScript. Parses the .jsonl session files that pi stores in ~/.pi/agent/sessions/, extracts user messages, computes stats: daily breakdown, project distribution, hourly activity, work categories, skill usage, message lengths, first and last message of each day.

Going to run this weekly now. Partly to see where time actually goes vs where I think it goes. Partly for content.
