fix: revert claude review trigger to pull_request#2152
Merged
Conversation
Reverts the pull_request_target trigger back to pull_request. The pull_request_target trigger was introduced in #2145 to support fork PRs, but Anthropic's OIDC token exchange endpoint does not accept tokens from pull_request_target events, causing 100% failure rate on all reviews since March 9th. This is a known upstream issue: anthropics/claude-code-action#713 Until Anthropic adds pull_request_target to their OIDC allowlist, we revert to pull_request which works for same-repo branch PRs.

Problem
The Claude Code Review workflow has been failing on every single PR since March 9th with:
Root Cause
PR #2145 changed the trigger from
pull_requesttopull_request_targetto support fork PRs. However, Anthropic's OIDC token exchange endpoint does not accept tokens frompull_request_targetevents — it only allowlistspull_requestin the OIDCevent_nameclaim.This is a known upstream bug: anthropics/claude-code-action#713
Fix
Revert to
pull_requesttrigger, which restores working automatic code reviews for all same-repo branch PRs.Tradeoff
Fork PRs will not get automatic Claude reviews until Anthropic fixes the upstream issue. This is acceptable since the majority of PRs to this repo come from same-repo branches.
