Hacker News comment item 50288423, posted 2026-10-29 by Asyakguen in the thread for the story Claude Code regularly sends each background agent’s transcript to its model, records a comment that asks whether almost all tokens would be cache hits if the entire transcript were sent for a summary, and says that the 16.4 percent figure comes from the Claude Code cost_usd estimate, so cheap per token still adds up when it is 1 in 5 requests.
Verbatim Excerpts from Cited Records
“If they are literally sending the entire transcript and asking for a summary, wouldn't almost all of the tokens be cache hit?”

“Maybe. But the 16.4% is from Claude Code's own cost_usd estimate, so cheap per token still adds up when it's 1 in 5 requests.”

Counter-record: The comment is a question followed by a qualified maybe, not a measured result, and the 16.4 percent figure is attributed by the commenter to the Claude Code cost_usd estimate, not independently verified here. The claim documents only what this comment says, not the underlying transcript or cost behavior.
Falsification probe: If HN comment 50288423 is deleted without archive, if the author edits the comment so the quoted sentences no longer match verbatim, or if the author posts a retraction of the comment, this claim drops to Withdrawn.
