It's September 23rd, 2026, and this is Headroom Daily.
The lead today is cost honesty. A customer benchmark showing just over double the cost with Headroom in front of Claude Code drove half a dozen fixes across tool handling, caching, and savings reporting.
First, tool schema deferral. The root cause was upstream: Claude Code turns off its own tool search when pointed at a proxy, inlining about sixteen thousand tokens of schema every turn. Headroom's response, in PRs 3739, 3745 and 3746, was to make its own deferral safe to run alongside clients. It now clears both…
Second, cache and accounting. PR 3735 stops description and system compaction from rewriting text the provider has already cached, which had flipped cheap cache reads into full-price writes. PR 3744 removes the floor that clamped losses to zero, so a losing deployment now reports negative savings with throttled…
Third, a parallel security sweep to fail closed. PR 3723 disables remote code execution in tokenizer loading and allow-lists known repositories. PR 3724 refuses binary downloads without a hash pin instead of installing with only a log line.
What's next: expect dashboards to show losses that were previously hidden…
