Environment
- roborev: v0.54.1 (downloaded by
roborev init gh-action generated workflow)
- claude-code: tried v2.1.128 (native stable channel), v2.1.139 (npm), v2.1.140 (native latest) — all fail identically in CI
- Runner: GitHub Actions
ubuntu-latest (24.04)
- Local (working): macOS arm64, claude-code v2.1.139 native install, same roborev v0.54.1
Symptom
roborev ci review --comment running inside a pull_request Actions workflow fails for every review job in <2 seconds with no surfaced stderr:
2026/05/12 22:19:13 ci review: running agent=claude-code type=security ref=...
2026/05/12 22:19:13 ci review: running agent=claude-code type=default ref=...
## roborev: Review Failed (`...`)
All review jobs in this batch failed.
- **claude-code** (default): failed
- **claude-code** (security): failed
Both jobs die before claude could plausibly produce output. roborev --verbose doesn't change anything. There are no per-job log files in /tmp/roborev, ~/.roborev, $RUNNER_TEMP/roborev, $GITHUB_WORKSPACE/.roborev, or /var/lib/roborev — verified by post-failure dump step.
What works in CI (sanity-checked in the same workflow run)
claude --version → emits versionecho "hi" | claude --print --output-format=text --dangerously-skip-permissions → returns Hi! What would you like to work on? (real API response)echo "review this: console.log('hi')" | claude --print --output-format=json --dangerously-skip-permissions → returns a valid JSON result block in 4s
So claude-code is installed correctly, ANTHROPIC_API_KEY is valid, network reaches Anthropic.
What fails identically in CI AND locally
echo "..." | claude --print --output-format=stream-json --dangerously-skip-permissions → exits 1 with stderr:
Error: When using --print, --output-format=stream-json requires --verbose
This is a claude-code v2.1.x behavior across multiple versions tried.
What works locally
roborev ci review --ref <base>..<head> --gh-repo ... --pr ... runs to completion and emits a real multi-finding review. Same roborev v0.54.1 binary, same .roborev.toml, same claude-code (v2.1.139 native). The local run takes ~25 seconds vs <2 seconds in CI.
So roborev does pass --verbose to claude in the daemon-less ci review path locally (otherwise local would fail with the same error). But something differs in CI — most likely path-of-execution, Linux vs macOS code path, or non-TTY handling — and the --verbose flag is not reaching claude in CI, OR something else fails before that point.
Confirmed NOT the cause
CLAUDECODE env var (forced empty via unset CLAUDECODE — same failure)- claude-code version: tried v2.1.128 (stable), v2.1.139 (npm), v2.1.140 (latest native); all same
- Install method: tried
npm install -g @anthropic-ai/claude-code AND curl claude.ai/install.sh | bash; all same
ANTHROPIC_API_KEY validity (sanity check confirms it works)- App token issues (
actions/create-github-app-token mints successfully; GH_TOKEN is well-formed)
What would unblock this
Surfacing the captured claude stderr in the failure-case output (the binary contains claude exited: %w (stderr: %s) per strings, but the message doesn't reach Actions stdout or any log file we can find).
If ci review is supposed to pass --verbose to claude when using --output-format=stream-json, that flag isn't making it through on Linux/Actions.
Repro workflow

https://github.com/Fantasy-Interactive/ix-myagent2webmcp/blob/chore/roborev-gh-actions-setup/.github/workflows/roborev.yml
Workaround request
Is there a roborev config option to pass extra agent flags through (--verbose), or a way to force ci review to use --output-format=json (non-streaming) which works in this CI environment?
