Session Diagnose

Diagnoses Claude Code session bloat — token count, context-window usage %, and what's eating your context.

UtilitiesBeginner★ 372⑂ 36AI score 7/10Last updated: Jul 3, 2026

What it does

Runs cozempic current --diagnose to profile your current Claude Code session:

  • Weight: total session bytes and message count
  • Tokens: exact token count from usage data, or a heuristic estimate
  • Context bar: visual percentage of the detected 200K or 1M context window
  • Vital signs: progress ticks, file-history snapshots, system reminders, thinking content, signatures, tool results
  • Breakdown by message type plus the top 10 largest messages
  • Estimated savings for each prescription: gentle / standard / aggressive

When context usage exceeds 60%, it recommends /cozempic:treat with a level matched to session size (under 5MB → gentle, 5–20MB → standard, over 20MB → aggressive).

Who it's for

  • Claude Code users with long sessions that keep filling the context window
  • Anyone tracking token consumption to control cost
  • Anyone who wants to see what's bloating a session before compacting it

Examples

  1. Ask "how big is this session?" → get token count and context percentage immediately.
  2. Context hits 78% → the skill suggests /cozempic:treat standard.
  3. Responses feel sluggish → inspect the top 10 largest messages to find the offending tool output.
