README

time-blame

A Claude Code mod that answers one question after every turn: was Claude slow, or was it your `npm test`?

It splits each turn's time by cause and shows it under the answer: in the terminal as a coloured line in place of Claude Code's "Worked for" line, elsewhere as a dim log line. `/blame` opens a panel with the whole session's split as a coloured bar. Claude never reads any of it, and nothing leaves your machine.

![time-blame in a real Claude Code session: after the answer, the line shows Claude 15s and npm test 27s, then /blame opens the panel](site/assets/time-blame-demo.gif)

A real run on Claude Code 2.1.302, in a small demo project whose test suite takes about 13 seconds. The waits are shown at 6× speed, as the clip says. Of the 47 seconds, Claude took 15 and `npm test` took 27. [Watch it as a video](https://timeblame.aidojo.si/#watch).

The same two outputs in plain text, from an earlier live session. This is what you get outside the terminal, or where nothing can draw a panel:

⏺ time-blame: 26s · Claude 8.0s (7.2s before output) · sleep 4.7s · you 12s · other 0.3s

⏺ time-blame: this session, this machine · 1 turn · 26s of turn time
⏺ time-blame: Claude     8.0s   31%  before output 7.2s, writing 0.8s
⏺ time-blame: tools      4.7s   19%  sleep 4.7s
⏺ time-blame: you         12s   49%  approvals 12s
⏺ time-blame: other      0.3s    1%  not attributed: hooks, local work, gaps
⏺ time-blame: longest turn 26s. Times are summed waits measured in this session, not server speed.

Both blocks are copied as text from that session, where a permission dialog was left open for 12 seconds before it was approved.
