aster-review-ci

name	aster-review-ci
description	Run aster code reviews non-interactively in CI, GitHub Actions, or from another agent. Covers `aster review --pr`, `--json`, `--stream`, `--comment`, diff-from-stdin, token handling, and filtering findings. Use when wiring aster into a pipeline, posting PR comments, or parsing review output programmatically.

Aster review in CI and automation

aster review reads a diff, hypothesizes defects, verifies them against the indexed repo, and reports findings. Everything is flag-driven; nothing requires a terminal.

Picking the diff

aster review                          # current branch vs its base
aster review --range main..HEAD       # explicit git range
aster review --diff changes.patch     # a saved diff file
git diff main... | aster review --diff -   # diff from stdin
aster review --pr 123                 # fetch a GitHub PR's diff

--pr needs a token: --token, else GITHUB_TOKEN, else the one stored by aster login. The repo defaults to the origin remote; override with --repo owner/repo.

Machine-readable output

aster review --json                   # findings as one JSON array
aster review --stream                 # NDJSON progress events, one per line

Use --json in CI and pipe it to aster fix or your own tooling. --stream is for editors and UIs that want live progress. --tui is the interactive browser; never use it headless.

Posting to the PR

aster review --pr 123 --comment       # post findings as inline PR comments

--comment implies --pr. Run it only when you intend to publish; the plain run is read-only.

Scoping and thresholds

aster review -i "src/**/*.rs" -x "**/generated/**" --min-confidence 0.7

• -i/--include overrides include from aster.yaml; -x/--exclude adds to it. Both repeatable.
• --min-confidence <0.0-1.0> drops weak findings; falls back to aster.yaml.
• --no-index skips the symbol index for speed, at the cost of weaker verification. Prefer keeping the index in CI.
• --repo-root <DIR> points evidence retrieval at a checkout other than the cwd.

Minimal GitHub Actions shape

- run: aster review --pr ${{ github.event.pull_request.number }} --comment --json > findings.json
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    ASTER_API_KEY: ${{ secrets.ASTER_API_KEY }}

The API key comes from ASTER_API_KEY (never from aster.yaml). An aster.yaml committed to the repo supplies models, analyzers, and filters; aster init -y writes a default one.
