Summary

  • move Codex and legacy OpenCode setup behind explicit review-agent profiles
  • keep shared PR eligibility, diff integrity, sandbox execution, cleanup, and artifact handling in the common wrapper
  • make the OpenCode path a removable legacy profile without changing behavior
  • cover the profile contract in the PR review tests

Validation

  • go build ./...
  • go vet ./...
  • CGO_ENABLED=0 go test ./...
  • make test-suite
  • bash -n and shellcheck for changed shell scripts
  • actionlint for review workflows

Summary by CodeRabbit

  • New Features

    • Added support for selecting Codex or OpenCode profiles for automated pull request reviews.
    • Review profiles now manage setup, validation, credentials, workflows, and result collection.
    • Codex reviews can automatically create temporary review environments using workflow-provided credentials.
    • OpenCode reviews support existing or temporary workspaces with supported provider configuration.
  • Documentation

    • Updated review documentation and CI guidance for available profiles and temporary workspace setup.
  • Tests

    • Added coverage for profile capabilities, bootstrap setup, cleanup, and result handling.

Walkthrough

The PR moves Codex and OpenCode configuration, setup, validation, workflow selection, and output extraction into agent profiles. The shared wrapper delegates these operations. Workflow inputs, tests, and documentation support Codex bootstrap and profile-based review execution.

Changes

Review agent delegation

Layer / File(s) Summary
Agent profile lifecycle
scripts/review/agents/codex.sh, scripts/review/agents/opencode.sh
Both profiles now implement configuration, credential checks, workspace setup, workflow and validator selection, and output extraction.
Shared wrapper integration
scripts/pr-review.sh
The wrapper sources the selected profile, delegates runtime operations, and cleans up created Codex and GitHub provider resources.
Codex bootstrap workflow wiring
.github/workflows/*.yml, docs/ci.md
The workflows pass Codex bootstrap settings and the API key to the wrapper. The CI documentation describes ephemeral workspace and provider setup.
Validation and documentation
test/pr_review_test.go, scripts/review/README.md
Tests cover profile loading, lifecycle functions, workflow wiring, and successful Codex bootstrap cleanup. Documentation describes profile ownership and review requirements.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to e04d3

A malformed local bootstrap setting can run against the configured workspace instead of creating an ephemeral one. Reject invalid values before merging or explicitly accept this bounded configuration risk.

Reject invalid CODEX_BOOTSTRAP values.

Local direct-target runs invoke scripts/pr-review.sh with environment configuration. Any value other than exact lowercase true sets configured_target=true, skips bootstrap setup, and passes codex_workspace to the task runner. A typo or TRUE can redirect a Codex run to the configured pre-provisioned workspace. Accept only true and false, and return an error for other values.
