Tam Nhu Tran 179fa338b8 hotfix(ci): increase max-turns to 30 and enforce Write tool for review output
- Increase --max-turns from 20 to 30 (large PRs with 31 files need ~25 turns)
- Explicitly instruct Claude to use Write tool (not Edit/python3 fallback)
- Add READ-ONLY constraint to prevent source code modifications
- Previous run hit error_max_turns at turn 21 despite successfully writing review

# AI Code Review Workflow
# Uses anthropics/claude-code-action with GLM routing via GitHub App tokens
# Same-repo PRs stay on the self-hosted cliproxy runner; external PRs use ubuntu-latest
#
# Triggers:
# - Automatically when PR is opened, receives new commits, or is reopened
# - Manually via /review comment on PR
# - Manually via workflow_dispatch
#
# Note: Concurrency group cancels in-progress reviews when new commits arrive.
# This prevents wasting resources on outdated code reviews.

# Smart concurrency: Prevents self-cancellation when bot posts review comment
#
# Problem: When the bot posts a review comment, GitHub fires an issue_comment event.
# This new workflow run joins the same concurrency group and cancels the in-progress
# run BEFORE job `if` conditions are evaluated - causing "operation was canceled" error.
#
# Solution: Non-actionable triggers (bot comments, comments without /review) get a
# unique per-run group, while legitimate triggers share the PR-based group for proper
# cancellation of outdated reviews.

## IMPORTANT: Writing the Review
After completing your analysis, use the `Write` tool to write the final review markdown to `${{ env.REVIEW_OUTPUT_FILE }}`.
Do NOT use `Edit` tool — use `Write` tool directly to create the file in one shot.
Do NOT post any GitHub comments yourself. The workflow will publish the saved file.
Do NOT modify any source code files — this is a READ-ONLY review.
End your review with:
> 🤖 Reviewed by `${{ env.REVIEW_MODEL }}`
IMPORTANT RULES:
- Use `Write` tool to overwrite `${{ env.REVIEW_OUTPUT_FILE }}` with the complete review
- Do NOT use shell operators like || or && in bash commands
- Do NOT use heredoc (<<) syntax in bash commands
- Use simple, single-purpose bash commands only
