From 01f9fb2a4ad6110def531ead16b370c818e8ee81 Mon Sep 17 00:00:00 2001 From: Adam Malczewski Date: Mon, 19 Oct 2026 17:02:40 +0900 Subject: feat(chat): cache timer for Claude Code subscription models Per-step and per-turn timers for the gaps between model requests (the Claude prompt cache expires after 5 min idle). A step gap runs live under the executing tools from step-complete until its last tool result (or the next step's output), then is stamped on that step's metrics line beside its cache badge. A turn gap runs live on the turn's metrics line from done/error until the next message is sent, then is stamped there. Counts m:ss up to 10 min, then '10+ min'; colour tracks the 5-min TTL. Gated on claude/. Pure reducer in core/metrics/cache-timer.ts; the turn gap is seeded from an idle conversation's lastActivityAt so it survives a reload. Stamps are in-memory only. --- src/app/views/ChatPane.svelte | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/app/views') diff --git a/src/app/views/ChatPane.svelte b/src/app/views/ChatPane.svelte index 636cd7c..31e719e 100644 --- a/src/app/views/ChatPane.svelte +++ b/src/app/views/ChatPane.svelte @@ -7,13 +7,18 @@ * preservation, the ScrollToBottom affordance, and the empty-state * watermark.
