This is part three of a series about pointing an append-only audit log at things that count tokens. Part one found that a single missing model line was half my AI agent overspend. Part two found two accounting bugs in splitrail, both of which undercounted — one hid 54% of my messages.
This one points the other way. The target is claude-code-templates — 30.1k stars, 3.3k forks, the largest Claude Code template repo — and its analytics over-counted my tokens by 2.35×.
The part that changed how I wanted to write this up: while drafting the report I went looking for whether the behaviour was documented anywhere. It is. Anthropic's own SDK documentation has a warning box about it, and ships a reference implementation of the fix. The bug was not hiding. Four separate mechanisms surrounded this code and none of them closed the loop, and the reason they didn't is the actual subject of this post.
The fix has now been open for ten days. Two AI reviewers approved it. No human has replied. More on that near the end, because the silence turned out to carry information too.
(Part four is the stated-vs-revealed routing analysis I promised at the end of part two. It got bumped. This was worth the detour.)
