Headroom Daily: Cache Misses and False Savings Fixes
Compression in the OpenClaw plugin was defeating prompt caching at thousands of times the cost of tokens saved, while cost reports showed zero dollars or silent defaults. Today's activity centers on cache-stable compression, honest pricing, and new IDE connectivity.

Hello and welcome to Headroom Daily for Sunday, September 27th, 2026.
Today's central theme is making savings real. Compression work was breaking prompt caching at massive scale, while cost reporting was quietly guessing.
First, cache stability in the OpenClaw plugin. PR 3811 found the system prompt addition changed every compressing turn because it embedded the per-turn tokens-saved count. Since the system prompt anchors the cached prefix, that small notice caused a roughly 93-thousand token cache miss on Bedrock, about four…
Second, honest pricing. PR 3821 fixes the savings tile, which was pricing nothing and displaying the absence as zero dollars because the cost estimator had no provider to work with. PR 3825 stops silent defaults for unknown models — you'll now get a once-per-model warning naming the fallback tier, plus a flag so…
Finally, connection completeness. PR 3817 adds native Google Antigravity IDE integration using the proxy-only wrap pattern, plus automatic install into the global M C P config. PR 3816 closes a gap on the direct chat path, which now answers the retrieve tool locally instead of forwarding it. Small reliability wins…
What's next: watch cache hit rates…
