Axiom LiftTHE CONTEXT LOSS TEST

Compacting conversation…

How much of your work does your AI remember?

When a conversation fills up, Claude Code swaps it for a summary. Your own Claude reads your sessions and shows what each compaction dropped. Axiom Lift keeps it.

Paste in the terminal where you use Claude Code
curl -fsSL "https://www.axiomlift.ai/install.sh?test=amnesia" | sh
  • Installs Axiom Lift (free) and finds every compaction on your computer.
  • Say yes to using your own Claude Code (in the background: no tools, nothing saved), pick how many sessions to test, and make your free account right there. Your report opens in your browser.
  • Every future session is reported automatically.

On your phone?

It reads your Claude Code history, so it runs on the computer where you code. We'll email you the command.

THE FOUNDER'S REPORT (ONE SESSION, 3 COMPACTIONS)

75%

kept, as his own Claude judged it. 9 of 36 decisions, rules and dead ends didn't make it into the summaries. Axiom kept all 36.

Press it. Watch what Claude keeps.

A sketch of one of the founder's sessions. The three rules that turn red are real ones his Claude summaries dropped.

CLAUDE'S SUMMARY

Empty for now: Claude has the whole conversation. Press ▶ Compact and it swaps it for a summary, here.

Survived
–

What Claude forgot, from the founder's own sessions

His own instructions. Gone.

"DO NOT silently merge inconsistent baselines."A rule he gave. Not in Claude's summary.
"Do not prematurely redesign it because a sparse version is weak."A rule he gave. Not in Claude's summary.
"Never interrupt an actively running foreground command."A rule he gave. Not in Claude's summary.
How it's checked

Your own Claude reads it

For each compaction, the conversation before it and the summary Claude kept go to your own Claude Code, on your computer. It lists the decisions, rules and dead ends that mattered and says which the summary still carries, quoting it. Rephrasing counts.

What it uses

Only with your yes

Your Claude runs in the background with no tools and saves no session; it uses a little of your allowance. Your reports go to your private Axiom account with your sessions, like any install. Privacy
