# coding.sh blame

git blame with the agent session that wrote each line. Every option of coding.sh blame, from its own --help.

coding.sh blame --help

```
coding.sh blame <PATH[:LINE[-END]]> [options]

  git blame with the agent session that wrote each line

Arguments
  path[:line[-end]]  A file in the repo, optionally one line or a range (src/app.ts:40-60)

Options
  --rev <REV>     Blame the file as of this commit (default: HEAD)
  --repo <DIR>    A directory in the git repository (default: the current one)
  --since <WHEN>  Match only commits after this time (default: the first captured session in the repo)
  --fresh         Wait for every pending capture to be ingested (default: answer after 1.5 s)

Examples
  coding.sh blame src/app.ts
  coding.sh blame src/app.ts:40-60
  coding.sh blame src/app.ts --json

Notes
  Each line shows the commit that last changed it and, when a captured session wrote that line, the session and agent; '-' means no session did. Matching works as in coding.sh attribution.
  --json: {root, rev, path, unattributed, sessions, lines: [{line, commit, text, sessionId?, agent?, model?, confidence?, method?}]}.
```
