Adds cachemiss to the CLI Utilities section, as suggested in #1804.

cachemiss reads the same ~/.claude/projects/**/*.jsonl transcripts ccusage does and lists every prompt-cache rebuild with its reason (the message.diagnostics.cache_miss_reason field when present, otherwise inferred and marked as such), the tokens rewritten, and the write premium over a cache read, grouped by session, agent, and model. Cold starts are priced separately from rebuilds. It is a diagnostic for why a cache was rebuilt, complementary to ccusage's accounting; it has no dependencies and is on PyPI as cachemiss.

One line added, no other changes.


Summary by cubic

Adds cachemiss to the community projects CLI Utilities section. It lists every prompt-cache rebuild from Claude Code transcripts with the rebuild reason (from message.diagnostics.cache_miss_reason when present, otherwise inferred and marked as such), tokens rewritten, and the write premium over a cache read, per session, agent, and model. One line added, no other changes.

Written for commit 64e1757. Summary will update on new commits.

Summary by CodeRabbit

  • Documentation
    • Updated the cachemiss CLI utilities guide to explain that it uses the reported cache-miss reason when available; otherwise, it infers the rebuild reason and identifies it as inferred. The guide also notes that cachemiss reports prompt-cache rebuilds, their causes, rewritten tokens, and cache-write premiums by session, agent, and model.
