Fix tri-* CLI: pipe diff via stdin instead of argument - #26
Merged
Conversation
$(cat /tmp/diff.txt) as a CLI argument hits shell ARG_MAX on large diffs,
producing empty output. Both Codex and Gemini support stdin:
- Codex: stdin appended as <stdin> block when prompt also provided
- Gemini: stdin appended to -p prompt
Changed to: cat diff.txt | codex/gemini -p "{prompt}"
This was the root cause of empty Codex/Gemini output in tri-reviews
this session — not a Gemini bug.
