Use organization Actions variables for Codex and Claude model/effort selection and CODEX_CLI_VERSION for the Codex npm release (latest or an exact version). Missing configuration fails before provider execution; review headings follow the configured model and effort. Review jobs use ubuntu-24.04-arm.

Claude action integrations use maintained anthropics/claude-code-action@v1 and its own CLI installer. Existing specialist routing, trust checks, tool restrictions, completion checks and publication remain in place.

Replace the removed Codex --full-auto option with the supported --sandbox read-only review option. Build/test jobs retain their existing runners.

Validation: Actions lint and git diff --check passed. Provider settings and invocation changes were inspected. Hosted execution of trusted-base workflows will exercise the new implementation after merge.

Summary by CodeRabbit

  • Chores
    • Updated automated pull request checks to use a newer runner environment and configurable review settings. The checks now validate review settings and CLI versions before running, and automated code review runs in read-only mode. These updates affect development workflows only; no user-facing product behavior has changed.

📝 Walkthrough

Walkthrough

The workflow adds repository-configured Claude and Codex model and effort settings, validates the values used by the review jobs, and moves all eight AI-review jobs to ARM runners. Codex jobs also use a configurable CLI version and read-only sandbox mode.

Changes

AI review workflow

Layer / File(s) Summary
Workflow settings and runners
.github/workflows/pr-ci.yml
The workflow adds repository-variable settings for Claude and Codex models and effort, plus a Codex CLI version. All eight AI-review jobs move to ubuntu-24.04-arm.
Claude review configuration
.github/workflows/pr-ci.yml
Each Claude review validates and passes the configured model and effort to the action. The action reference changes from a pinned SHA to @v1.
Codex review configuration
.github/workflows/pr-ci.yml
Each Codex review validates model and effort patterns and accepts only latest or a numeric three-part CLI version. It uses the configured values and --sandbox read-only instead of --full-auto.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~15 minutes

Change: Feature

Merge Risk: 🟡 Moderate · up to 8e5b5

The AI review jobs now load the Claude action through a movable version tag while holding an OAuth credential. If that tag is changed upstream, the jobs would run the new code with the credential. Restore the commit pins before merging. Codex review headings also do not show the configured model and effort; this is a smaller issue.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 8e5b5

Review automation will run mutable third-party code with credentials and repository write permissions. Existing eligibility checks reduce exposure, but cannot prevent compromised release code from accessing those credentials.

Retained concerns

  • Medium · security · observed: Credential-bearing review executables lose a fixed-identity guarantee. Four Claude jobs now resolve mutable @v1 instead of a reviewed SHA, allowing upstream release changes to alter secret-consuming code without a repository change. Codex has the same conditional exposure when CODEX_CLI_VERSION is configured as latest; its current value is unknown.
Security review details

Security Blast Radius

  • inferred — Control of the shared Claude release reference can affect up to four eligible review jobs in this repository, exposing their supplied provider credential, checked-out source, and repository issue/pull-request write authority. The id-token permission is visible, but downstream cloud access is not established. Provider-account and cross-repository reach remain unknown.

Security Findings and Attack Paths

  • inferred — The retained finding identifies a mutable action consuming an explicitly supplied OAuth credential. An attacker able to replace code selected by @v1 could execute it during an otherwise eligible review run and obtain credentials or alter review results. This newly weakened action identity is confirmed against base; it does not require bypassing the fork gate and does not demonstrate an actual compromise.

Trust Boundaries and Controls

  • observed — As written, the eligibility gate blocks fork PRs, missing credentials, and changes to review automation paths. Claude retains restricted model tools and Codex adds read-only sandboxing. These controls constrain eligibility and model activity, rather than the third-party implementation that receives credentials.

Resilience and Maintainability Implications

  • inferred — Per-PR cancellation and 20-minute job timeouts bound continued execution, but cannot recover a credential already read by compromised code. Explicit session-file cleanup or token revocation was not identified; this lifecycle dependency predates the PR, and external teardown guarantees remain unverified.

Hardening Proposals

  • proposed — Preserve immutable action revisions and use exact CLI releases for credential-bearing review execution, updating them through reviewed changes. Assess transitive installers separately; pinning the wrapper alone does not establish their integrity.

The description explains the main workflow changes and validation results, but it does not follow the required template and omits explicit sections for scope, change type, risk and rollout, breaking changes, assumptions, exceptions, workarounds, linked issues, and reviewer notes.

Resolution

Rewrite the description using the repository template. Complete the required headings and check applicable scope, change type, risk, breaking-change, validation, and rollout items. State assumptions, exceptions, workarounds, linked issues, and reviewer focus, or explicitly mark them as not applicable.

P1 Badge Restore the immutable Claude action pin

Pin each Claude review job to a full commit SHA rather than the mutable @v1 tag. If that tag is moved to an incompatible or compromised release, these jobs will immediately execute unreviewed third-party code with CLAUDE_CODE_OAUTH_TOKEN, pull-request/issue write permissions, and an OIDC token; the adjacent comment and previous value show that the SHA pin specifically protected this boundary. Update to the desired v1 release's immutable SHA instead.

Include the configured model and effort in Codex review headings.

These four publication steps still emit fixed headings. Changing the configured model or effort does not change the published heading. Reviewers cannot distinguish the configurations from these headings.

Add $CODEX_REVIEW_MODEL and $CODEX_REVIEW_EFFORT to all four Codex headings.

Example correction for the contracts heading
-            echo "## Codex Review - Cairo/Starknet Contract Review"
+            echo "## Codex Review ($CODEX_REVIEW_MODEL, effort=$CODEX_REVIEW_EFFORT) - Cairo/Starknet Contract Review"

Based on PR objectives, review headings must follow the configured model and effort.

CWE: CWE-829 — Inclusion of Functionality from Untrusted Control Sphere

Restore immutable pins for all four Claude action references.

If an attacker compromises an upstream maintainer account and retargets v1, subsequent review jobs execute the replacement action with CLAUDE_CODE_OAUTH_TOKEN. The replacement action can steal that credential. The PR trust checks and --allowedTools do not restrict the action implementation. GitHub documents this risk for mutable action tags. (docs.github.com)

Pin the reviewed release to its full commit SHA at Lines 509, 752, 995, and 1239. Keep the release version as a trailing comment.

Based on learnings, third-party actions must use full immutable commit SHA references.
