        ## Upstream Sync Required

        Our \`main\` branch is **${BEHIND} commits behind** upstream (\`anthropics/claude-code-action\`).
        We are **${AHEAD} commits ahead** (our Forgejo-specific changes).

        ### New upstream commits (latest ${BEHIND}, max 30 shown)

        \`\`\`
        ${COMMIT_LOG}
        \`\`\`

        ### Files changed

        \`\`\`
        ${DIFF_STAT}
        \`\`\`

        ### How to merge

        \`\`\`bash
        git fetch upstream main
        git merge upstream/main
        # Resolve any conflicts in the 3-4 modified files (run.ts, tag/index.ts, etc.)
        bun test
        git push origin main
        \`\`\`

        ### Conflict-prone files

        These files have Forgejo modifications and may conflict:
        - \`src/entrypoints/run.ts\`
        - \`src/modes/tag/index.ts\`
        - \`src/mcp/install-mcp-server.ts\`
        - \`action.yml\`
